A NEW SPECIES OF CISTALIA FROM BRAZIL
AND COMMENTS ON SYSTEMATIC CHARACTERS IN THE
LETHAEINI (HEMIPTERA: LYGAEIDAE)1

ABSTRACT
Cistalia micans a new species from Brazil, is described and figured. The
highly modified nature of the sperm reservoir in the Lethaeini is discussed.
The potential importance of sperm reservoir morphology in understanding
phylogenetic relationships within the tribe is noted. The iridescent head
patches of Cistalia are discussed in relation to other genera and to sperm
reservoir modifications. Figures of the sperm reservoir, clasper, genital cap-
sule, and SEM photographs of the iridescent head patches are included.


The genus Cistalia StAl is a small genus of chiefly Neotropical lygaeids.
The systematics of the genus has been reviewed by Slater and Baranowski
(1973). Recently a striking new species from Brazil has become available
for study. The male phallus of this species is so strikingly different from
those of other lethaeines with which we were familiar that we were led to
investigate representatives of several additional genera in an effort to
better understand the position of Cistalia within the tribe.

semierect to decumbent hairs; antennal segments clothed largely with de-
cumbent pubescence, several upright hairs present but these shorter than
diameter of an antennal segment.
Head moderately convex across vertex, non-declivent anteriorly; tylus
evenly rounded, not quite attaining middle of first antennal segment; lat-
eral margins of juga carinate. Compound eyes large, touching antero-
lateral margins of pronotum. Length head 0.75 (all measurements in milli-
meters), width head 0.92, interocular space 0.52. Pronotum with transverse
impression shallow, obsolete; posterior lobe distinctly punctate, more
heavily so than anterior lobe, calli impunctate; scattered punctures pres-
ent near anterior pronotal margin; lateral margins evenly narrowing an-
teriorly, carinate; posterior margin shallowly concave. Pronotum 1.02
long, 1.60 wide. Scutellum shallowly rugose, distinctly and evenly punc-
tate, ecarinate. Scutellum 0.92 long, 0.85 wide. Claval commissure 0.45
long.
Hemelytra with lateral corial margins feebly sinuate, nearly straight,
tapering posteriorly; clavus with 4 distinct rows of punctures; corium with
cubitus strongly elevated above surface, membrane extending to or
slightly beyond end of abdomen; distance apex-clavus to apex-corium 1.05;
distance apex-corium to apex-abdomen 0.75. Metathoracic scent gland au-
ricle nearly straight or slightly curving caudad distally, apex subtrun-
cate; evaporative area large, occupying ventral 2/3 of metapleuron, the
lateral (dorsal) margin truncate but sloping ventrad posteriorly. Fore
femora slightly incrassate, armed below with 2 short stout spines distally
and several elongate prominent hairs proximal to these on ventral sur-
face; middle and hind femora mutic. Labium extending posteriorly to meta-
coxae, first segment reaching base of head; length labial segments I 0.70,
II 0.70, III 0.55, IV 0.38. Antennae moderately stout, first segment some-
what enlarged on distal 1/2; segments 3 and 4 slightly fusiform. Length
antennal segments: I 0.80; II 0.98; III 0.82; IV 0.92. Total length 4.90.
This species is closely related to Cistalia binotata Slater and Bara-
nowski and will run to binotata in Slater and Baranowski's (1973) key.
Three species of Cistalia (alboannulata Stal, binotata S. & B., and micans
n.sp.) form a distinct group within the genus because of the nearly straight,
evenly narrowed lateral pronotal margins. C. binotata and micans are the
only Cistalia species that have the outer portion of the corium polished and
shining and the inner half a strongly contrasting dull pruinose.
C. micans can readily be distinguished from binotata by having a pol-
ished and shining rather than pruinose scutellum, by lacking prominent
white spots near the posterior end of the corium and distally on the clavus,
by having an appreciably longer first antennal segment and by having the
shining area of the corium extending further mesad.
The sperm reservoir of Cistalia micans is so highly modified from the
generalized lygaeid type that morphological relationships are difficult to
understand.

SPERM RESERVOIR RELATIONSHIPS

The generalized condition in the Lygaeidae is of a sperm reservoir with
a bulb, the ventral portion of which is cup-shaped and strongly sclerotized
(sclerotized cup) with a pair of "wings" projecting from the membranous

dorsal portion of the bulb (Fig. 2, 3). From the base of the sclerotized cup
arises a large strongly sclerotized ejaculatory duct (=seminal duct) that
passes ventrad of the sclerotized cup (Fig. 3) and continues distally through
the aedeagus (see Slater and Harrington 1970 for a definition of terms and a
more detailed discussion of function).
In Cistalia the sclerotized portion of the "bulb" appears to have become
greatly enlarged and to be continued distad of the membranous area of the
bulb as a complete tubular or cylindrical structure (Fig. 7, 8). Within this
large heavily sclerotized "cylinder" lies a coiled tube that emerges dis-
tally from a large opening in the sclerotized "cylinder." This coiled tube
appears to arise near the base of the bulb. The sclerotized wings are reduced
to small strips (Fig. 8) that curve ventrad around the sclerotized portion
of the bulb. Ventrad of the bulb and attached to the bulb near the base is a
peculiar sheath-like, somewhat corrugated structure that becomes evanes-
cent distally. This structure definitely does not carry a tubular connection
to the distal portion of the aedeagus.
The sperm reservoir of Cistalia is so modified that it is difficult to un-
derstand the relationship of the ejaculatory duct to that of the generalized
condition. It is our belief that the ejaculatory duct has become incorporated
within the enormous "cylinder" which actually seems to have been formed
from an enlargement of the sclerotized cup and an enlargement of a basal
ventral sclerotized "spur" (see below). It is tempting because of its basal
connection to view the peculiar sheath-like ventral structure as the non-
functional original ejaculatory duct. We do not believe this to be the case.
Not only is there no evidence of a tubular duct associated with this corru-
gated structure but more importantly such an interpretation would neces-
sitate the development of a completely new duct within the sperm reservoir
whereas the corrugated sheath-like structure could be developed merely
by modification of already existing membranes in the phallus.
A structurally similar modification of the sperm reservoir area occurs
in Cryphula and in Petissius.
In species of the Lophoraglius guttulatus "complex" (Old World
Tropics) the sperm reservoir area is very different (Fig. 5), yet it, too, is not
of the generalized lygaeid type. In this complex the ejaculatory duct in-
stead of curving ventrad "below" the sclerotized "cup" curves in exactly
the opposite direction so that it passes above or "in front of' (dorsad of) the
membranous portion of the bulb. Since these structures are completely and
rigidly sclerotized at their point of basal attachment, this cannot result
from merely a "flipping over" of the ejaculatory duct to enable it to run
on the opposite side of the bulb from the plesiomorphic position. It is pos-
sible that the sclerotized cup portion of the bulb has developed in these
insects on the opposite side from where it originally was, and that the orig-
inally sclerotized area has become membranous. Some support for this
hypothesis might appear to come from the "wings" which in many lygaeids
curve around the sclerotized cup toward the ejaculatory duct below. In the
Lophoraglius complex the wings extend strongly from the membranous
bulb toward the ejaculatory duct. Attractive as this hypothesis might be,
there does not seem to us any evident adaptive advantage for such a drastic
structural modification.
In many Lygaeinae and some Blissinae the sclerotized basal area from
which the bulb and ejaculatory duct arise is enlarged and often has a ven-

tral sclerotized spur. It is possible that the guttulatus-type modification
has been achieved by the reduction of the cup so that the bulb arises directly
from the basal sclerotization. The peculiar position of the wings (Fig. 5)
would seem to support this hypothesis. If this is so it will also account for
the modifications found in Cistalia where the spur-like ventral develop-
ment of the basal area of the sperm reservoir presumably enlarges, sur-
rounds the ejaculatory duct, and becomes fused with the cup. The above
interpretation seems to us to be the most parsimonious explanation for the
striking modifications of the sperm reservoir area found in these lethaeines.
From a systematic viewpoint the most important considerations are
these: (1) The Lophoraglius type of sperm reservoir also occurs in species
of Valtissus, Xestocoris, and Lipostemmata, all of which are Western
Hemisphere genera. (2) The "Cistalia-type" and the "Lophoraglius-type"
reservoirs are both highly apomorphic conditions. (3) Neither of these types
of sperm reservoir modifications can be directly derived from the other.

Slater and O'Donnell: New Cistalia Species


Ashlock (1964) notes that 6 New World genera of Lethaeini have a syn-
apomorphic feature at the base of the head dorsally. The 6 genera have a
single median iridescent area whereas in other genera 2 iridescent areas are
present. It is significant that all 3 genera with a single iridescent area that
we have investigated have the Cistalia-type sperm reservoir (Cistalia, Cry-
phula, Petissius), further evidence that a holophyletic group is involved.
We have made a few preliminary observations on the nature of the
"double iridescent head patches" as compared to thoracic lethaeine irides-
cence. The iridescence of these 2 surfaces is very different. SEM photographs
(Fig. 9, 10) of the head patches show that they are formed of a series of fine
corrugations arranged in 4 rows to form a circle: only a semicircle is visible
when the head is intact. The pronotal iridescence by contrast is formed by a
field of minute pegs scattered across the cuticular surface (Fig. 11, 12).
The corrugated rows that form the iridescent head patches are visible
under high power of a good light microscope. We have not been able to de-
tect these corrugations in species with a single median basal iridescent head
patch. As with the sperm reservoir these iridescent areas appear to offer val-
uable characters for a more mature understanding of phylogenetic rela-
tionships within the Lethaeini.

treatment of endopterygote insects has been changed so that the 9 Panorpoid
orders are together. Each volume has an extensive, independent index.
Bibliographies follow each chapter and have occasional citations as recent
as 1974-76, though in general the research preparation for this edition seems
to have wound down in 1970-71. A quick survey of the references of 4 chapters
in Vol. 1 revealed a mean increase of 118% with a mean of 64% published
since 1957.
"The tenth edition of this standard reference text, covering all aspects of
entomology, has been revised and extensively rewritten, reflecting the
broader scope of entomology today while retaining the features responsible
for its past success ... the structure and physiology of the insects are treated
in a series of general chapters, each describing a major organ-system and
incorporating the results of much recent research. Where the advances in
our knowledge have been the greatest, as in the chapters on the cuticle,
nervous-system, sense-organs and glandular structures, large sections have
been rewritten ...."
A general textbook of entomology is almost if not impossible to write
today. With over 8,000 publications (Imms' count) on the subject each year,
who could claim to be sufficiently knowledgeable in all areas to synthe-
size and summarize them, to bring each up to date and keep them there
while writing other sections? I think it amazing that anyone would try,
but of course these authors were not starting from scratch. Updating and
following the format of a classic old book could be worse than doing a
fresh one: the key to the new Imms' is that it is still a classic old book,
constructed along the same lines, with much of the old core, and dominated
by things rather than ideas. For example, while more than a page is given
to a discussion of reproduction in aphids, and special terminology and life-
cycles are given, nothing is said of the biological significance of sexual
and asexual phases, or the possibilities for research on evolutionary phe-
nomena, or of the use of certain theoretical considerations for making pre-
dictions to guide further study. While there are more than 90 pages on the
Hymenoptera, and several pages indexed for "social life", nothing is said of
the more than 10-year discussion and development of kin selection which
has altered thinking and direction in the field considerably, and the dis-
coverer W. D. Hamilton (one of their guys) isn't even mentioned. The index
gives no entry for "sex ratios"-I note also that it gives only 1 for sex
pheromones. "There are about 1700 species (actually 1891 as of 1966) of
"glow-worms" and "fire-flies" (note the quaint quotation marks and hy-
phens) and 2 are British" (The European Continentals who have done far
more research on the 2 species than the British, don't know they are British.)
Although an extensive study was made on the 2 in Germany by Schwalb
(1960), the new Imms' cites Newport (1837; should be 1857). I note "Lloyd
(1971) has reviewed communication by means of light-signals", but I might
add that he did more viewing than reviewing, none of which got mentioned,
alas. There is no chapter dealing with behavior (or ecology for that matter),
not even a descriptive one, or even one on insect ethology, Tinbergen him-
self being cited but once (1951). The "new" Imms' may be a necessity for
any entomological library, but if you wish to use it as a core text for an
entomological program it must be supplemented extensively, and students
will need a government subsidy to buy it in hardback. JEL

ATTRACTION OF EUPHASIOPTERYX OCHRACEA',
CORETHRELLA SP.2 AND GRYLLIDS TO BROADCAST
SONGS OF THE SOUTHERN MOLE CRICKET3'4

JOHN R. MANGOLD
Department of Entomology and Nematology, University of Florida,
Gainesville, Florida 32611

ABSTRACT
Females of the parasitic tachinid Euphasiopteryx ochracea (Bigot), the
culicid Corethrella wirthi Stone or ally, and 7 gryllid species were at-
tracted to broadcast calling songs of the southern mole cricket, Scapteris-
cus acletus Rehn and Hebard, in Florida. A 14 month study of E. ochracea
attraction to S. acletus calling song indicated E. ochracea was attracted
from May through December, with greatest numbers attracted in September,
October, and early November.



Soper (1974) and Soper et al. (1976) first showed that a parasite can find
its host by sound; the sarcophagid Colcodamyia auditrix Shewell can lo-
cate its cicada host, Okanagana rimosa (Say), by the male cicada's song.
The tachinid Euphasiopteryx ochracea (Bigot) has also been attracted to
the calling song of males of its host, Gryllus integer Scudder (Cade 1975).
Female flies of both species larviposit on their hosts, usually adult males.
On 29 May 1975 Dr. T. J. Walker, Department of Entomology and
Nematology, University of Florida, collected an E. ochracea female 1 h
after sunset from the speaker of a tape recorder broadcasting the calling
song of Scapteriscus acletus Rehn and Hebard in Alachua Co., Florida.
The host(s) of E. ochracea in Alachua Co., were unknown-i.e., Alachua Co.
is outside the range of Gryllus integer (Nickle and Walker 1974). Also, no
parasites of S. acletus, an important agricultural pest, are known; a simi-
lar fly, E. depleta (Wied.), has been reared from the Changa mole cricket,
S. vicinus Scudder in Brazil (Wolcott 1940, 1948). A study was made to con-
firm auditory attraction and to determine the seasonal attraction of E.
ochracea to S. acletus calling song.


METHODS AND MATERIALS
Recordings of the natural calling song of S. acletus males at 250C soil
temperature were broadcast using equipment like that described by Ula-
garaj and Walker (1973). At this temperature S. acletus calling song has a
pulse rate of 60 pulses/sec, a carrier frequency of 2.8 kHz, and an intensity
range of 42-106 dB as measured 15 cm above the male burrow entrance (Ula-
garaj and Walker 1973, Ulagaraj 1976).

scissa indicate weeks of no observations. Lack of significant monthly differ-
ences at the 5% level of error based on Duncan's multiple range test at site
2 are indicated by same letter underneath a month.


Two test locations were used: (1) from 9 July 1975 to 3 September 1975,
a pasture surrounded by mesic hammock near Gainesville, NW 1/4, Sec.
31, T9S, R19E, the site of the fly captured by Walker, (site 1) and (2) from
16 September 1975 to 16 September 1976, SE 1/4, Sec. 23, T9S, R19E, 1.6 km
NE of site 1 (site 2). The second site was a residential yard bordering mesic
hammock; it was selected because more E. ochracea were collected here
than at site 1.
To determine whether E. ochracea could be attracted to broadcast song,
a 0.5 m X 0.5 m white cloth was placed under the speaker and a cylindrical
electric grid, described by Mitchell et al. (1972), was placed over the
speaker. An identical apparatus including a speaker was not connected to
calling song output and served as a check. The electrical grid and speaker
combination used to broadcast calling song was alternated with each suc-
cessive test date. The speakers were modified by removal of the flared-horn
end and were placed on their sides, 3 m apart. Broadcasts began ca. 30 min
after sunset. Both grids and ground cloths were inspected with a flashlight
for an equal length of time every 30 mih for the first 1 and 1.5 h after sunset
at sites 1 and 2, respectively. The intensity of the broadcast songs was main-
tained at ca. 96 dB and 105 dB as measured 15 cm from the speaker front, at
sites 1 and 2, respectively, using a sound level meter (General Radio Model
No. 1551-B). Broadcasts were made at least 3 times monthly, except for 2

Mangold: Tachinid Attraction to Gryllid Songs 59

E. ochracea attraction observations to sound source at site 2; the data were
transformed to /x + 0.5 for analysis.

RESULTS AND DISCUSSION
Euphasiopteryx ochracea-A total of 97 E. ochracea females was collected
from the broadcasting apparatus. No E. ochracea were collected from the
check. E. ochracea females were sometimes observed flying to the broad-
casting speaker at the beginning of a broadcast. On some occasions these
tachinids were collected on evenings when no Orthoptera were taken. E.
ochracea were attracted in significantly greater numbers during September,
October, and November than other months, although the number attracted
in September was not significantly different from the number attracted in
November (Fig. 1). These results agree with Sabrosky's (1953) report that
E. ochracea adults apparently fly in late summer through fall. Lower
temperatures at broadcast time during the winter probably did not con-
tribute to an absence of attracted tachinids since Cade (1976) found E. och-
racea in Texas flew to Gryllus integer calling song at temperatures as low
as 10.6C.
As a preliminary test of the host suitability of S. acletus and the south-
ern field cricket, Gryllus rubens Scudder, for E. ochracea development, lar-
vae dissected from a female E. ochracea abdomen were placed on males of
these crickets by touching cricket abdomens to larvae.
E. ochracea successfully developed to adulthood on 1 of 5 S. acletus
males and on the 1 G. rubens male artificially infested. Since there are nu-
merous examples of parasites developing on factitious hosts (Simmonds
1944), the rearing of E. ochracea on S. acletus does not prove that the latter
is a natural host. The rearing of 5 E. ochracea adults from an adult Gryllus
sp. collected on 22 October 1976 (J. R. Mangold unpubl.) may indicate that
Gryllus spp. are important hosts in the fall.
The reduction in Gryllus spp. calling song activity during the peak period
of E. ochracea attraction to S. acletus calling song may indicate that the
seasonal patterns of Gryllus calling songs in north central Florida are in-
fluenced through parasitism by E. ochracea. Directional or disruptive se-
lection against Gryllus calling during September to November caused by
E. ochracea parasitism may be partially responsible for reduced calling
during this period. Calling by G. rubens males is most frequent during Jan-
uary to April in Alachua Co. (T. J. Walker unpubl.), but the greatest num-
bers of adults are found in the fall in north Florida (Veazy et al. 1976).
Similarly, Veazy et al. (1976) found 2 peaks of G. firmus Scudder adults,
June to mid-August and September to November, but calling males were
present in peak numbers only during June to late August (T. J. Walker
unpubl.). Calling males of G. fultoni (Alexander) are heard throughout the
year except for October to mid-December (Walker 1974). Furthermore G.
ovisopis Walker, the only Gryllus sp. known to lack a calling song, occurs
as an adult from September to mid-December (Walker 1974) which is during
the time E. ochracea is attracted to S. acletus calling song in greatest num-
bers.
Gryllidae-The following 7 species of crickets were collected from the
broadcasting speaker apparatus: Neonemobius nr. mormonius, N. cubensis
(Saussure), Oecanthus niveus (De Geer), 0. celerinictus Walker, S. acletus,













The Florida Entomologist


S. vicinus, and G. rubens. Ulagaraj and Walker (1973) previously reported
the latter 4 cricket species and N. cubensis have calling songs similar to
S. acletus and were attracted to S. acletus calling song. Eighteen female
and 12 male 0. niveus and 2 female and 1 male N. nr. mormonius were
found at the broadcasting speaker; 3 female and 3 male 0. niveus were
found at the check. Neonemobius nr. mormonius and 0. niveus also have
calling songs similar to S. acletus (T. J. Walker pers. comm.).
Corethrella Species-On 2 September 1975 I noticed small midges on and
within 20 cm of a broadcasting speaker after the normal broadcast period.
These flies were later identified as females of Corethrella wirthi Stone or
ally, culicids of the subfamily Chaoborinae. On the following night and on
9, 17, 23, 31 July and 15 September 1976 ca. 4-30 midges were observed at the
broadcasting speaker at 1.5 h after sunset, while no midges were observed
at the check.
Recently, McKeever (1977) reported Corethrella brakelyi (Coquillet)
and C. wirthi females feeding on 3 species of tree frog, Hyla spp. in Georgia
and presented circumstantial evidence of their attraction to host (frog)
calls. It seems plausible that Corethrella sp. were attracted to mole cricket
calling song because of its similarity to tree frog calls.

GREENHOUSE EVALUATION OF FOLIAR MITICIDES FOR
CONTROL OF BROAD MITE ON CITRUS-(Note).' Sulfur is the
only material currently recommended for control of the broad mite,
Polyphagotarsonemus latus (Banks), on citrus in Florida (J. R. King 1960:
Ann. Rep. Fla. Agr. Exp. Sta. p. 200). Since its repeated use against this
pest is contrary to the program of reduced sulfur advocated by citrus pest
management specialists, a miticide less harmful to beneficial insects is
desirable.
Alternative compounds were sought among 13 candidates tested in the
fall of 1974 for efficacy against broad mites infesting immature foliage
of 'Key Lime' seedlings, Citrus aurantifolia, grown in the Research Center's
greenhouse.
Seventy seedlings, naturally infested with broad mites, were removed
from the greenhouse and randomly assigned to 14 groups of 5 plants each.
Tender terminals of each plant were inspected under 30X magnification to
determine pre-treatment mortality for the first 20 adult or nymphal forms
encountered on each plant. Per cent mortality was determined in a similar
manner 1, 5, and 14 days after treatment to assess performance of test
compounds and an untreated check.
The plants were inverted and immersed for 10 sec in 5 gal of treatment
solution. Control plants were immersed in tap water. After treatment,
plants were positioned on the center bench in a 2nd greenhouse in a ran-
domized block design.
No moribund or dead individuals were found in the pretreatment search
of tender terminals. One day after treatment, mite death due to the follow-
ing 4 compounds (tested at the indicated grams AI/378 liters) had exceeded
the 90% mortality level arbitrarily considered acceptable for initial kill
and effective control: 357 g DS-20630 (12% tetranactin + 30% 2-secondary-
butylphenyl-N-methyl carbamate), 170 g MalonobenTM (3, 5-di-t-butyl-4-
hydroxybenzylidenemalononitrile), 226.8 g dicofol, and 93.7 g PGP-102
(trihexyl(phenylsulfonyl)stannane). Two weeks after treatment, only
Malonoben, dicofol, and PGP-102 were effective enough to suggest that a
single application would suffice for control of field populations.
Tricyclohexylhydroxytin 85 g, 113.4 g chlordimeform, 56.7 g chloro-
benzilate, 119.3 g propargite, 113.4 g azinphosmethyl, 181.8 g dialifor,
226.8 g phosalone, 56.7 g oxamyl, and 51.1 g formetanate were not effective
at the rates tested.
Hamlen (1974:J. Econ. Ent. 67:791-2) reported significant reduction of
broad mites within 2 weeks with 2 applications of oxamyl in his green-
house study. Several compounds in the current test might, if applied twice,
provide control comparable to Malonoben, dicofol, and PGP-102. How-
ever, the current strategy in citrus pest management is to reduce further the
number of sprays applied to the crop, thereby favoring materials that would
control the pest with a single application.
When Malonoben was applied as a "clean-up" spray in the greenhouse
at the completion of the experimental work, it was found to be phyto-
toxic to foliage of 'Etrog' citrons (Citrus medical var. etrog).-R. C. Bullock,

HEMOCYTES OF MOSQUITO LARVAE1

D. W. HALL2 AND S. W. AVERY3

ABSTRACT
Plasmatocytes, oenocytoids, and granular hemocytes inside the anal
papillae of larval Culex tarsalis Coquillett, Psorophora ciliata (F.),
Aedes aegypti (L.) and A. atlanticus Dyar and Knab were described follow-
ing examinations by light and electron microscopy. Observation of these
hemocytes is a convenient method of monitoring changes in hemocyte num-
bers in vivo.


Most hemocytes of mosquitoes are sessile and adhere to other tissues,
thus making counts and histological studies of them difficult (Jones 1953,
1962). Amouriq (1960) described the hemocytes of Culex hortensis Ficalbi
from panchrome-stained smears. Bhat and Singh (1975) obtained hemocytes
of Aedes albopictus (Skuse) by rupturing the heart and applying pressure to
the abdomen. Jones (1958) reported that the hemocytes of 4th-instar larvae
of Aedes aegypti (L.) could be readily observed in vivo by light microscopy
through the thin transparent cuticle of their anal papillae. In this paper we
describe the types and structure of the hemocytes found in the anal papillae
of 4 species of mosquitoes.

MATERIALS AND METHODS
The hemocytes of larvae belonging to all 4 species of mosquitoes were
examined by light microscopy. Two species, A. aegypti and Culex tarsalis
Coquillett, were obtained from laboratory colonies maintained at the In-
sects Affecting Man Research Laboratory, Gainesville. The other species,
Aedes atlanticus Dyar and Knab and Psorophora ciliata (F.), were col-
lected from the field. Hemocytes of A. aegypti and A. atlanticus also were
examined by electron microscopy.
For light microscopy, larvae were narcotized in a 1% solution of pro-
caine-HC1 and the anal papillae were examined with phase-contrast. For
electron microscopy, anal papillae were excised and fixed overnight in cold
Karnovsky's fixative. They were then post-fixed in 1% Os0, in 0.1M cacody-
late buffer for 1 h, dehydrated and infiltrated with either epon or Spurr's
low viscosity medium (Spurr 1969). Prior to polymerization, each papilla
was examined by light microscopy, and those containing few hemocytes
were discarded. Papillae containing numerous hemocytes were then em-
bedded 1 per block and oriented so they could be sectioned in the longitudi-
nal plane. Thin sections were stained in uranyl acetate and lead citrate
(Reynolds 1963).
Fourth instar A. aegypti were exposed to 100 ppm of neutral red, and
the hemocytes were examined for concentrations of the dye as an indicator
of lysosomes.

RESULTS AND DISCUSSION
Three classes of hemocytes were observed: plasmatocytes, oenocytoids,
and granular hemocytes. Only plasmatocytes and oenocytoids were ob-
served in A. aegypti (Fig. 1). Granular hemocytes were observed in some
specimens of A. atlanticus (Fig. 2), P. ciliata and C. tarsalis.

Plasmatocytes are by far the most common hemocytes in mosquitoes.
Those in the anal papillae are usually fusiform and are found adhering to
the papillar epithelial cells or to tracheae. The ultrastructure of these
cells is similar to that of plasmatocytes of other insects as described by
Arnold (1974). They have a relatively large nucleus, and the cytoplasm
contains numerous mitochondria and ribosomes (Fig. 3).
Most plasmatocytes and oenocytoids rapidly sequestered neutral red
in vivo, which suggests the presence of lysosomes (Allison and Young 1969,
Holtzman 1976). Some plasmatocytes contain numerous membrane-bound
phagosomes, and are presumably phagocytic (Fig. 4).
Oenocytoids are hyaline, ovoid to spherical cells which are highly re-
fringent when viewed with phase-contrast microscopy (Fig. 1). They are char-
acterized by the presence of numerous microtubules and a few mitochondria
and Golgi elements (Fig. 5).
Granular hemocytes differed slightly in appearance in the different spe-
cies examined, primarily in the size and appearance of the granules. Granu-
lar hemocytes of A. atlanticus contained large lipid droplets. Granular
hemocytes and oenocytoids were relatively uncommon in mosquito larvae
when compared to plasmatocytes.
Counting the hemocytes of the anal papillae of mosquito larvae is a
convenient method of monitoring the hemocyte condition of living larvae.
Anal papillae may also be excised in fixative, and hemocytes counted at
leisure. Andreadis and Hall (1976) have utilized this method to estimate
changes in total hemocyte numbers and changes in dopaoxidase-positive
hemocytes of A. aegypti larvae parasitized with a neoaplectanid nematode.

JUVENILE HORMONE ANALOGUES: EFFECTS OF ZR-777
ON LIRIOMYZA SATIVAE AND ITS ENDOPARASITE-(Note).
Several authors (Wright, J. E., and G. E. Spates. 1972. Science 178: 1292-3;
Wilkinson, J. E., and C. M. Ignoffo. 1973, J. Econ. Ent. 66:643-5) have found
that juvenile hormone analogues (JHA) adversely affect host insects, with-
out disrupting the development of internal parasites. Others (Vinson, S. B.
1974. J. Econ. Ent. 67:335-6; Granet, J., et al. 1975. Ent. Exp. & Appl.
18:377-83; Riviere, J. L. 1975. Entomophaga 20:373-9) have reported adverse
effects on host as well as parasite when parasitized hosts were treated
with JHA. S.L. Poe (1974. Fla. Ent. 57:415-7) reported that ZR-777, at high
rates, not only greatly reduced adult emergence of Liriomyza sativae
Blanchard, but also suppressed Opius dimidiatus (Ashmead) emergence.
The experiment reported here was conducted to determine if the effects of
ZR-777 were sustained at lower doses on L. sativae and 0. dimidiatus.
Insects for treatment were obtained from a greenhouse colony on bean
plants. Parasites were confined, for 24 h, with caged plants containing
3-day-old host larvae. Then the plants were removed from the "parasitiza-
tion cage", and host larvae allowed to grow in leaves for 2 days after
parasitization. Leaves were excised and placed in paper cartons in which
host larvae pupated. Pupae were collected and brought to the laboratory
where they were treated with the JHA ZR-777 (Pro-2 ynyl 3, 7, 11- trimethyl
- (2E, 4E) 2, 4 dodecadienoate) Ent. No. 70531, synthesized by Zoecon
Research Laboratory.













The Florida Entomologist


The JHA was used at 1,000, 1,250, 1,500, 2,000, and 3,000 ppm. Pupae
were divided into 6 groups, placed on separate paper towels, and sprayed
with 5 dosages (Table 1) of JHA with a small hand sprayer. The 6th
group was sprayed with water. After treatment, pupae were placed in paper
cartons and kept in the laboratory (temperature 20-250C, RH:46-74%). The
experiment was replicated 3 times.

Counts of emerged insects were made 20 days after treatment. Adult
insect emergence was relatively low in the control (Table 1) probably a
result of rearing conditions. Only at 3,000 ppm JHA, was adult L. sativae
emergence reduced significantly. Each dose of JHA significantly reduced
parasite emergence, but observed effects among doses were not significant
(Table 1). These data confirm that JHA at rates sufficient to disrupt host
development are also detrimental to natural enemies. K. M. Lema, and S.

PERICEROS (HYMENOPTERA: ICHNEUMONIDAE) IN
MEXICO, WITH COMMENTS ON INSECT DISTRIBUTION
IN THE NORTHERN NEOTROPICS1

CHARLES C. PORTER2

Department of Biological Sciences, Fordham University,
Bronx, N. Y. 10458

ABSTRACT
Xorides (Periceros), previously known from Perfi, Brasil, and Argentina,
now is reported for northeast M6xico. X. (Periceros) cerbonei n. sp. is de-
scribed from Cola de Caballo near Monterrey, and a key is given to all
Neotropic Xorides. Besides Periceros, many other insects traditionally be-
lieved restricted to tropical wet forests actually reach northern Mexico.
Zoogeographic implications of this distributional pattern are discussed.



The cosmopolitan genus Xorides, which parasitizes wood-boring co-
leopterous larvae, is well represented in most zoogeographic regions, in-
cluding, for example, 21 Nearctic species, but seems to have a meagre al-
though widely distributed and in part trenchantly distinctive Neotropic
fauna. Townes (1960:497) gives 1 Mexican record for the basically Nearctic
X. (Exomus) humeralis (Say), but no other Xorides heretofore have been
cited from Middle America. Porter (1975:51-6) reviewed the South American
species, citing X. xanthisma Porter and X. euthrix Porter from northeast
Argentina, X. plumicornis (Smith) from Amazonian Brasil and Peri, and
X. magnificus (Mocsary) from southern Brasil and adjoining Argentina.
Xanthisma is an aberrant member of the otherwise mostly Holarctic sub-
genus Xorides Latreille, while euthrix and plumicornis belong to the
specialized and endemically Neotropic Periceros Schultz, and magnificus
is the sole representative of the South American subgenus Pyramirhyssa
Mocsary.
In June 1976, during fieldwork supported by United States National Sci-
ence Foundation Grant DEB-75-22426, I collected 3 males of an unde-
scribed Periceros at Cola de Caballo in Nuevo Le6n State of northeastern
Mexico. These records not only constitute a dramatic range extension for
the subgenus but are equally surprising because the South American Peri-
ceros inhabit subtropical and tropical wet forests, while the Mexican spe-
cies was taken at the northern extreme of the Neotropics where the climate
is humid but practically warm-temperate and the flora resembles that of
the southeastern United States.
Herewith, I describe the new Mexican Periceros and adduce some ex-
amples of other distributionally similar insect taxa.

apical 1/3 smoother and more sparsely punctate; baso-lateral corner cut
off by a deep oblique groove that reaches lateral margin of tergite about
1/3 the distance to apex and that turns meso-apicad as a broader but still
strong impression that, with the basal grooves, delimits a broadly raised,
ovoid median area on basal 2/3 of tergite and this median raised area itself
subdivided into a pair of transversely rounded, anterio-lateral swellings

The Florida Entomologist


Comparison with plumicornis is tentative because we have no females of
cerbonei and no males of plumicornis, but the characters already mentioned
in the key probably hold true for both sexes. Furthermore, the oblique
epomia, smooth and polished 1st gastric tergite, and very densely and uni-
formly setose temple and mesopleuron of plumicornis likewise should
prove diagnostic with respect to cerbonei, in whose males at least the
epomia is vertical, the 1st gastric tergite strongly wrinkled, the temple
rather sparsely setose, and the mesopleuron becomes less densely setose
centrad.
On the other hand, having examined 8 males of euthrix, I find, in addi-
tion to the key characters, numerous differences from cerbonei and these
may be summarized as follows.
Last labial palpomere securiform; front with almost uniformly strong
puncto-reticulation; anterior edge of interantennal lamella sharp and
ungrooved; temple with setae throughout extensively overlapping; ocel-
lar area not definitely discrete from rest of vertex, no longitudinal groove
behind mid ocellus; vertex and occiput with numerous medium-sized punc-
tures; pronotum laterally with numerous but well separated large punc-
tures that emit long but only moderately overlapping white setae; scu-
tellum with moderately dense setae; hind coxa almost parallel-sided and
very elongate, 5.8 as long as wide at widest point; 1st hind tarsomere 1.2
as long as tarsomeres 2-5 combined; area-basalis of propodeum 2.2 as long
as wide at base, it and areola with rather regular coarse transverse wrinkles;
1st gastric tergite long, slender, and only gently expanded apicad, post-
petiole 2.0 as long as wide at apex and with moderately fine, trans-biased
reticulate wrinkling; dorsal carinae not extending onto postpetiole; dorso-
lateral carinae obsolete on petiole, becoming sharp apicad on postpetiole;
2nd gastric tergite 1.1 as long as wide at apex, its setae sparse but in part
overlapping on disc, smooth and shining with numerous but sparse small
punctures and a little restricted weak wrinkling, its sharp, oblique, baso-
lateral grooves and fainter posterio-transverse impression defining on
basal 2/3 a moderately swollen, almost circular, and scarcely subdivided
median area.
FIELD NOTES. All specimens were found in deep forest. Two were netted
from herbaceous undergrowth, while the 3rd was collected from a recently
dead tree trunk.
SPECIFIC NAME. For Mr. Anthony Cerbone of Fordham University in
recognition of his assistance during my Mexican fieldwork.

BIOGEOGRAPHIC COMMENTS
Cola de Caballo, the type locality of X. cerbonei, is a deep ravine lo-
cated about 40 km south of Monterrey at approximately 500 m altitude on
the eastern slopes of the Sierra Madre Oriental. It has a permanent stream
and, facing east to west, gets little direct sun. Further shade is provided by
the thick forest that clothes its floor and sides. These factors create a humid
micro-environment whose lush vegetation contrasts with the surrounding
sparser woods and Thorn Scrub.
The Cola de Caballo flora has many northern genera, although numer-
ous species are Mexican endemics. Conspicuous trees are Acer, Carya, Jug-
lans, Platanus, Pinus, Quercus, and Taxodium. On the other hand, subtropi-

cal epiphytes grow on these temperate trees, including not only the familiar
Tillandsia usneoides and other much bulkier "tank" bromeliads but also
orchids, ferns, and Cactaceae.
Collecting since 1974 at Cola de Caballo and other sites in Nuevo Le6n
State has yielded a complex ichneumonid fauna in which 60% of the genera
are Neotropic. Besides Xorides (Periceros), previously recorded only from
South America, I have also obtained in Nuevo Le6n Zonopimpla, Ganodes,
Rhinium, Toechorychus, Latosculum, Cestrus, Nonnus, Oedicephalus,
Cryptojoppa, Joppocryptus, Microsage, Joppa, Eurydacus, and Diacan-
tharius, taxa for the most part hitherto unknown from north of C6rdoba,
1400 km south in tropical M6xico and all of which range far into South
America. As for other Neotropic genera of the area, Epirhyssa, Bicristella,
Carinodes, Dilopharius, and Macrojoppa reach only the southern fringe
of the United States but attain Argentina on the south; whereas, A crotaphus,
Grotea, Lymeon, Polycyrtus, Cryptanura, Messatoporus, Thyreodon, Me-
topius (Peltales), Trogomorpha, and Ambloplisus have 1 or a few species
widely distributed in temperate North America, particularly in the east, as
well as a greater representation in the tropics of both Middle and South
America. In addition to the foregoing ichneumonids, some other noteworthy
"tropical" elements among the Nuevo Le6n insect fauna are the euglossine
bee genera Eulaema and Euplusia and the pseudostigmatid zygopteron
genus Mecistogaster, whose nymphs develop in water that collects at the
base of the leaves of epiphytic tank bromeliads.
It is thus apparent that many Neotropic insects occur far north (and
south) of the tropical climates with which we instinctively associate them.
For example, the average January temperature at Monterrey, M6xico is
14.60 C, and Cola de Caballo suffers numerous winter frosts and some
snow. Moreover, 40 Neotropic ichneumonid genera (23% of the total fauna)
reach as far north as Maryland or New Jersey in the eastern United States,
where they generally are represented by 1 or a few species endemic to the
Temperate Deciduous Forest. Rainfall rather than temperature thus would
appear to be the major limiting factor for much of the Neotropic entomo-
fauna, and, indeed, the Thorn Scrub and Desert of Texas and northern M6x-
ico constitute a largely effective barrier to present-day interchange be-
tween the Mexican and southeast North American Neotropic faunas.
Furthermore, most Neotropic ichneumonid genera have vast geographic
ranges. Fully 67% (116) extend, like Periceros, at least from Mexico or
Central America to Brasil. Ample distributions of this type have been
noted for diverse groups of organisms. Raven and Axelrod (1975:427) re-
ferred to them in vertebrates and angiosperm plants. Hershkovitz (1972:240)
documented them for Neotropic recent mammals and, therefore, rejected
the traditional thesis that a substantial water gap separated South from
Middle America during the later Mesozoic and all of the Tertiary until
the Pliocene. Halffter (1976:40), mainly on the basis of scarabaeid beetles,
also believed that "ideas are changing about the Central American Land
Bridge and, therefore, with regard to the possibilities of Pre-Pliocene fau-
nistic exchanges between North and South America".
Analysis of Neotropic ichneumonids in any marginal area, such as
Nuevo Le6n or even the southeastern United States, helps strengthen the
above zoogeographic postulates. One is impressed by the immense distribu-
tions of so many Neotropic ichneumonid genera and by the uniformity of












The Florida Entomologist


the present-day Neotropic fauna in all regions from M6xico to Argentina.
This assemblage certainly does not appear to have evolved for scores of
millions of years in strongly isolated South and North American tropical
land masses. Indeed, there are only 4 (out of 174) endemic Neotropic ich-
neumonid genera in all the New World north of South America. The evo-
lutionary center for the Neotropic ichneumonid fauna was and is South
America. The assemblage probably originated there during the Cretaceous
and early Tertiary and then, essentially as a unit, rapidly overspread
almost the whole New World in moist, warm Palaeocene and Eocene
times, only to be pushed gradually out of North America by post-Eocene
climatic cooling and drying and finally decimated there by the Pleistocene
glaciations. It is not and never has been a "really tropical" fauna but
rather a humid-adapted forest element capable of surviving moderate and
regular winter frost but not the really harsh cold and invernally frozen
soil of genuinely boreal climates.
It is thus easy to see why Periceros should occur both in the subtropical
forests of northeast Argentina and the mountains of north M6xico. At vari-
ous times in the Tertiary such taxa could and did cross land bridges be-
tween South and Middle America. Since Xorides is best represented at pres-
ent in the Oriental Region, we may suggest for it a Palaeotropic origin with
various invasions of the New World via the Bering Land Bridge. The highly
differentiated, warm-adapted, and endemically Neotropic Periceros and
Pyramirhyssa probably are descendants of early, perhaps Palaeocene or
Eocene invaders, while the mostly Holarctic and more eurythermic Xorides
may have reached South America later in the Tertiary during a cooler
climatic epoch.

TWO NEW SOUTHERN PHIDIPPUS
(ARANEAE: SALTICIDAE)1

G. B. EDWARDS2

Department of Entomology and Nematology,
University of Florida, Gainesville, FL 32611

ABSTRACT
Two new species of Phidippus are described, P. xeros from Florida and
P. toro from the Chiricahua Mts. of Arizona.


This paper describes and provides a name for a new species of Phidippus
as part of an ongoing study by the author into the ecology of those species
of Phidippus that occur in Florida. Also, a new species of Phidippus is de-
scribed from the Chiricahua Mts. of Arizona (reported by Jung and Roth
1974, as P. n. sp.). Another new species occurring in the Chiricahua Mts. was
recently described by Gertsch and Riechert (1976).

The Florida Entomologist


Abdominal integument red-brown, covered with long, black setae;
markings consisting of white scale patches with a few white setae; iridiscent
black scales scattered sparsely in dorsal black areas; venter brown with
dark brown central stripe, 2 rows of tan punctate dots within central stripe,
1 row of similar dots on each lateral edge of central stripe, tan dots
throughout lateral brown areas; spinnerets brown covered with black setae.
Male palpus (Fig. 2) with slightly recurved embolus.
Thirteen males ranged from 5.9-10.2 mm in length, with a mean of 7.7
mm; however, all males at the small end of the range were laboratory-
reared from field-collected immatures, and at least some were probably
smaller than normal; 5 field-collected adult males averaged 8.8 mm in
length. The only other variation observed in males was in the size of the
white scale patches on the carapace.

Edwards: New Phidippus


Female: total length 9.84 mm; carapace length 4.37 mm, width 3.44 mm;
width ALE row 2.42 mm, width PLE row 3.05 mm; PLE-PME 0.81 mm, ALE-
PME 0.47 mm, PLE-PME/ALE-PME= 1.72.
Dorsal view as in Fig. 3. Structure and color pattern similar to male
with following differences: distinctive, white spot in center of ocular area,
all other markings orange-yellow; wide band encircling abdomen except
posteriorly; iridescent black scales more numerous than on male; leg for-
mula IV, I, II, III, much more extensive scale cover on legs, covering all
except distal ends of most segments and majority of femora I, II, and IV;
clypeus covered with long, white setae medially, orange-yellow scales
laterally; 4 small hair tufts, located 1 below and 1 behind each PME.
Epigynum (Fig. 4) with small anterior openings, extensive spermathecae.
Thirteen females ranged from 8.6-11.7 mm in length, with a mean of 10.2
mm. Considerable variation in dorsal pattern was encountered: scale
patches on carapace may be joined in middle and/or may connect with cly-
peus, at extreme completely encircling ocular area; carapace scale patches
may be light gray or yellow instead of orange-yellow; abdominal band
may be red-orange, may vary in width (sometimes covering most of central
black area), and in 1 female was absent, with only a pale yellow basal
band present.
DIAGNOSIS. Small carapace scale patches that are wider than long are
found, among southeastern U. S. species, only in P. xeros and P. pulcher-
rimus Keyserling, the latter being a much redder species. Female resembles
P. insignarius Koch, but is the only eastern species with a distinctive ocular
spot like that of P. workmani Peckham & Peckham from Arizona; male
resembles small P. audax (Hentz). The genitalia also distinguish P. xeros
from the other above-mentioned species.
ETYMOLOGY. Specific epithet from Greek, masculine; xeros, meaning
xeric, referring to the xeric habitats frequented by this species.

Edwards: New Phidippus


Dorsum of carapace and abdomen as in Fig. 5. Carapace integument dark
red-brown, ocular quadrangle black; broad, horizontal ridge anterior to
PLE (Fig. 8), covered at crest with suberect, elongate, yellow scales; at
each side of crest, behind PME, is large, elongate tuft of black setae curv-
ing forward above ALE to distance equal with AME; dense covering of
short, black setae between crest and anterior eye row; anterior eyes over-
hung by many yellow and white setae of moderate length and fewer long,
black setae; anterior eyes encircled by white scales; clypeus sparsely cov-
ered with long, white setae; chelicerae with long, white setae on lateral
and medial edges and covering proximal half, distal half iridescent green-
blue; lateral edges of carapace margined with thin row of white scales, sides
covered with short, black setae, thoracic slope with moderate length black
setae appressed with tips pointed posteriorly, with a few long, white setae
pointed anteriorly.
Sternum and coxae yellow-brown, labium and endites brown with pale
anterior edges. Integument of palpi and legs red-brown; palpus with long
white setal fringes on lateral edges of patella, distal end of tibia, and dis-
tal end of cymbium, long and short yellow setae covering proximal half
of cymbium. Leg formula I, IV, II, III, femur I larger than femora II-IV;
legs sparsely covered with black setae; lateral and distal parts of femora,
patellae, and tibiae of legs II-IV covered with light yellow scales. Leg I
as in Fig. 6, all scale patches light yellow, median femoral band yellow,
subventral band white, rest of femur covered with short, black setae; long,
dense white fringe on venter of patella, tibia, metatarsus and tarsus; spina-
tion, ventral tibia 2-2-2, metatarsus 2-2, dorsal distal femur 3, dorsal sub-
distal spine on femur elongate.
Abdominal integument red-brown, covered with short, gray setae and
very long, heavy black setae; markings of elongate white scales and a few
long, white setae; basal band thin, extending half length of abdomen, may
or may not join lateral stripe, lateral stripe becomes broken line to join
3rd spot pair. Venter yellow-brown with 4 rows of pale dots. Spinnerets
red-brown, covered with black setae.
Male palpus (Fig. 7) with long, recurved embolus.
A second male was 9.5 mm in length.
Female: total length 10.39 mm, carapace length 5.00 mm, width 3.75
mm; width ALE row 2.69 mm, width PLE row 3.19 mm; PLE-PME 0.73 mm,
ALE-PME 0.48 mm, PLE-PME/ALE-PME = 1.52.
Female like male except: integumental carapace ridge lacking (Fig. 9),
crest of scales white, appressed; weak to moderate band of white scales ex-
tending posteriorly from PME; leg formula IV, I, II, III, fewer scales on
legs, femur I covered with short, black setae, but otherwise leg I like legs
II-IV.
Epigynum (Fig. 10) with large, widely separated openings.
Eight females ranged from 9.4-10.4 mm in length, with a mean of 9.9 mm.
Variation: central abdominal spot often broken in middle.
DIAGNOSIS. The modifications of the carapace and leg I in the male, and

A NEW SPECIES OF BROMELIAD LYGAEID
FROM JAMAICA1,2

ABSTRACT
A new species of Ozophora from Jamaica, West Indies is described and
figured. The immature stages are also described. This species appears to be
restricted to mature seed heads of bromeliads in the genus Hohenbergia.
This restricted habitat is unusual since most species in the Rhyparochro-
minae are litter insects that feed upon fallen seeds on the ground.


The diverse and abundant bromeliad flora of the Neotropics presents a
series of habitats to which many different animals have become adapted.
Within the Heteroptera most associated species either suck the sap from
leaves and flowers (Tingidae, Miridae etc.), are predaceous upon other in-
sects associated with bromeliads (Anthocoridae) or live on the surface of
the water present in the "cups" of many species (Veliidae).
In this paper we report a species of rhyparochromine lygaeid that lives
on the mature seed of large Jamaican bromeliads while the seed heads are
still present on the plant. This represents a marked modification of habits
as the species belongs to a genus and subfamily the majority of whose mem-
bers are litter insects that feed upon fallen seeds on the ground.

Many specimens have the posterior lobe of the pronotum much more ex-
tensively darkened than does the holotype so that it gives the appearance

of 3 large chocolate brown lobes, 1 mesal and 1 on each side laterally
with an irregular pale yellow longitudinal streak between them. Some-
times this streak is separated into a pair of maculae on the anterior portion
of the posterior lobe and a pair along the posterior margin similar to the
condition found in Ozophora burmeisteri (Guerin) and other species. In the
majority of specimens the membrane is somewhat more fumose or darkened
than in the holotype and has a conspicuous white trianguloid apex. The
number of fore femoral spines is somewhat variable and in a number of cases
the 3rd from the proximal spine is absent leaving a distinct gap.
Despite the frequently dark appearance of the pronotum, hohenbergia
is closely related to Ozophora quinquemaculata (Barber). It is readily
distinguishable, however, by the more acuminate head and especially by the
elongate labium which, in this species, reaches the 4th abdominal sternum
whereas in quinquemaculata it at most only slightly exceeds the hind coxae.
So far as is known this species is restricted to the mature seed heads of
species of bromeliads of the genus Hohenbergia. At Faith's Pen it was taken
on H. polycephala (Baker) Mez.; at Linstead it was taken on H. penduliflora
(A. Rich) Mez.; and at Mandeville on H. urbaniana Mez. Both polycephala
and urbaniana are endemic while penduliflora is also known from Cuba.
FIFTH INSTAR NYMPH (Linstead, Jamaica): Body broadened, elliptical.
General coloration light testaceous yellow with intermixed darker mark-
ings but these latter still a light brown. Head nearly uniformly yellowish
brown with a conspicuous pale stripe running through vertex to base of
tylus and a pale macula behind each epicranial arm. Pronotum yellowish
brown mesally, laterally and midway between meson and margin, these 2
latter brown markings coalescing anteriorly and becoming relatively dark
brown near antero-lateral angles but not including explanate margin.
Scutellum and wing pads variegated with yellowish brown and nearly
white testaceous. Abdomen extremely conspicuously irrorate, segments 2
and 3 not completely fumose or dark gray as in many species of Ozophora
but uniformly irrorate. Legs completely pale yellow. Antennal segments
I, II and III yellow, 1st segment slightly infuscated, distal end of II very
slightly infuscated, distal 5th of III dark chocolate brown as is distal two-
thirds of IV, a conspicuous broad white annulus on proximal 3rd of segment
IV. Body below reddish brown on pleural area except dorso-lateral edges
of metapleuron and white to pale yellow on extreme meson of vertex. Ab-
domen below also uniformly irrorate.
Form and color as in most Ozophora. Labium very elongate, usually
extending to sternum 6, tylus reaching at least to distal 3rd of 1st anten-
nal segment. Fore femora often with only 3 ventral spines present. Head
length 0.75, width 0.83, interocular space 0.48; pronotum length 0.68, width
1.28; wing pad length 1.25; abdomen length 1.93; labial segments I 0.83,
II 0.88, III 0.90, IV .45 long, respectively; antennal segments I 0.35, II 0.95,
III 0.78, IV 1.10 long, respectively; total length 4.10.
INSTAR FOUR (same): General form and color as in instar 5. Labium rela-
tively more elongate usually reaching to abdominal sternum 7 with seg-
ment 3 reaching sternum 4. Head length 0.60, width 0.68, interocular space

spectively; antennal segments I 0.14, II 0.26, III 0.26, IV 0.42 long, respec-
tively; total length 1.10.
We are aware of only a few references to Rhyparochrominae associated
with bromeliads. Mumford (1965) reported Ozophora concava (Distant) as
intercepted in Texas in quarantine on bromeliads and Hunt (1958) reported
a similar occurrence for Cryphula apicalis (Distant) [sic] apicata. Neither
of these establish the species as more than casually associated with bromeli-
ads. Champion (1913) in an important paper which treated many bromeliad
insects described a new lygaeid as Pamera alboannulata (now in the genus
Lygofuscanellus) which was definitely associated with bromeliads in Costa
Rica. A breeding population was present as a male, 3 females and 2 nymphs
are mentioned in the original description. Unfortunately Champion does
not mention where these insects occurred on the host plants. He did not ac-
tually collect the insects but received them from a Monsieur C. Picado of
Paris.
It is interesting that both 0. concava and L. alboannulata belong to the
tribe Ozophorini (there has been some confusion concerning 0. concava and
Mumford's (1965) record may actually refer to Peggichisme consanguinea
(Distant), also an ozophorine).
Our acquaintance with Ozophora hohenbergia began on 10 December
1970 when we were collecting along a very steep hillside 1 mi. S. of Faith's
Pen, near the base of Mt. Diablo in the interior of Jamaica. We were sur-
prised that upon striking Hohenbergia seed heads over our nets several
specimens of Ozophora dropped into the nets. Eventually we were able to
obtain several nymphs, indicating that the species was indeed breeding in
the seed heads. The insects were scarce, however, and while most rhyparo-
chromines have food preferences and some are very restricted in food utili-
zation, others are more oligophagous and occasional breeding takes place
on peripheral, almost accidental, food sources.
In July 1971 we returned to Jamaica and attempted to discover how
closely associated with bromeliads this species of Ozophora actually was.
In most habitats the giant Hohenbergia bromeliads grow high in the trees
and it is difficult to reach them. At Linstead and Mandeville as well as
Faith's Pen by climbing into the trees and throwing the seed stalks into nets
below we were able to obtain many adults and many more nymphs. The
insects were not present in "green" seed heads nor in stalks from which the












The Florida Entomologist


seeds had fallen but were restricted to relatively fresh but completely
mature heads.
Adults are very similar in appearance to many other species of Ozophora
but the nymphs are quite distinctive. The nymphs of most species of Ozo-
phora are dark chocolate brown to almost black on the head and pronotum
with a strongly contrasting variegated abdomen. The nymphs of Ozophora
hohenbergia by contrast are almost uniformly pale yellowish brown. The
"typical" Ozophora color pattern is still present but has become so pale
that the nymphs appear unicolorous to the eye in the field and are very
cryptic among the seed heads of the bromeliads. Not only is the color in-
dicative of specialization to the host plant but the latter instar nymphs
(especially the 5th instar) are noticeably more flattened dorso-ventrally
than are most species of Ozophora.
The adaptation of rhyparochromines to habitats well above the ground
will probably prove to be relatively common in tropical rainforests. We
already know of species feeding upon seeds in bird droppings on leaves, in
the leaf axils of palms, in the understory, etc. The forest floor with its high
humidity that causes fallen seeds to either germinate rapidly or be destroyed
by fungi makes the litter habitat a very temporary one for lygaeids. It is
thus not surprising that various species adapt to the abundant food supply
present on plants above the ground particularly where the plants retain
their seeds for a considerable period of time after they become mature.
Although we have examined bromeliads in several genera over the past
7 years on many of the West Indian islands we have not found any other
hemipteran associated with the seed heads.

Jamaica, Kingston Jamaica) for identifying the bromeliads, and Mrs. Kathy

FLIGHT BEHAVIOR AND DISPERSAL OF
DIAPREPES ABBRE VIA TUS'

J. B. BEAVERS AND A. G. SELHIME

U.S. Horticultural Research Laboratory, Agricultural Research Service,
USDA, Orlando, Florida 32803

ABSTRACT
From July to October 1975, marked adult Diaprepes abbreviatus (L.)
(Coleoptera: Curculionidae) were released in an isolated orange grove near
Apopka (Orange County), Florida. Specimens were recovered for 50-52 days
following each of 2 releases. Multiple sightings were made of 42% of the
released females and 34% of individually coded males. Nearly 80% of the
sightings were made within 5 days of release.


An exotic curculionid, the so-called sugarcane rootstalk borer weevil,
Diaprepes abbreviatus (L.), was first found infesting citrus near Apopka
(Orange County), Florida, in 1964. The original quarantine area of ca. 2,000
ha established in 1968 has been extended 3 times to encompass ca. 13,350
ha by 1975 (Woodruff 1968, Selhime and Beavers 1972). In 1975, an infested
area was found near Forest City (Seminole County), Florida, ca. 14 km from
the Orange County area, and an additional 2,400 ha were placed under
quarantine.
Because the 2 quarantined areas are separated by a considerable distance
and infested groves within the quarantine areas are not necessarily contigu-
ous, flight behavior and dispersal of D. abbreviatus were studied. This in-
formation would be helpful in establishing management and control pro-
grams for this relatively new pest.

METHODS AND MATERIALS
Two tests were conducted near Apopka, Florida, in an isolated 20-ha
grove of 'Hamlin' oranges; the grove consisted of ca. 2,000 3 to 4-m tall
trees in a 7.6 x 7.6 m planting. No chemical treatments had been applied
there since 1969. Adult D. abbreviatus were field-collected and coded with
enamel paints (Cross and Mitchell 1964) 1-2 days before each of the 2 re-
leases were made on calm days (wind speed less than 1.6 km/h) in July and
October 1975. Adult weevils were placed on top of a 0.3-m-high cardboard
box in the center of a row (same site for each release).
On each release date we observed the flights and measured distances
flown from the release site for as many weevils as possible. Visual searches
of the trunks and lower canopies of at least 50-150 trees around the release
site were made at various intervals during the 8 weeks following each study.
The entire grove was examined weekly for the marked weevils.
Test I. Fifty males and 50 females, each individually color-coded, were
released 14 July to determine distances flown by adult weevils during a
period when little or no new growth (the preferred food source for the


'Coleoptera: Curculionidae.

adults) was present. The release coincided also with the period when the
weevil population generally begins to increase (Beavers and Selhime
1976). First observations were made 4 h after release. Subsequent observa-
tions were made daily during the first week, 3 times in the second week, and
once per week until 3 September. Individual adults were identified by color
code and then replaced on the tree.
Test II. Sixty-one males and 61 females were released 8 August to de-
termine adult weevil flight distances during a period when considerable
new foliage was present. These adults were marked with enamel paints so
that sex could be determined without disturbing the adults; i.e., a single
spot on males' elytra and 2 spots on the elytra for females. Observations
began 5 days after the release. Data were recorded at weekly intervals for
the first 5 weeks and at 2-5-day intervals for the last 3 weeks of observa-
tions.
RESULTS AND DISCUSSIONS

Test I. A total of 82 sightings was made during the 50 days following
the July release (Table 1). Many individuals in the original group of 100
were recovered more than once; 21 females accounted for 43 observations
(Table 1), and 17 males produced 30 observations. Data from these indi-
viduals were not extensive enough to demonstrate a sexual difference in dis-
persal distances through time. Some individuals (Male "8", Female "6")
consistently stayed close, within 9 m to the release site, while others flew
either greater distances (Female "18" at 99 m) after 30 days or changed lo-
cations more frequently (Male "11" at 3 m after 4 h, 18 m at 2 days, 236 m
at 9 days and 228 m at 50 days). The numbers of adults sighted decreased
markedly by 4 days after the release (Table 1).

Test II. The adults used in Test II were coded only for sex. Observa-
tions could be made without disturbing the adults, although use of this
method meant that the movement of individual weevils could not be fol-
lowed. Since observations were not begun until 5 days after release, the
bulk of weevil dispersal activity may have occurred in the interim period.
The numbers of individuals observed and the flight distances observed are
in accord with those observed over comparable time intervals in the July
release.
In dispersing from the release site, most of the adult weevils took flight
immediately, although some first crawled a short distance away from the
box. Before flight, the posterior of the abdomen was lowered, the elytra
were elevated, and the flight wings were fully extended. Most weevils flew
directly to the nearest tree from the release site or landed on weeds around
the tree canopy. Those flying longer distances (38-45 m) flew to ca. twice
the tree height and appeared to hover a few seconds before landing.
When disturbed, some adults feigned death by dropping to the ground
and remaining motionless; others hid in the trash on the ground. Still others
dropped off the leaves and took flight before hitting the ground. They usu-
ally landed on the first weeds or tree branches contacted.
From our limited field observations, D. abbreviatus is capable of strong
flight of short duration and distance. Once they have landed, they appar-
ently will remain in one place for long periods unless disturbed. Although
the releases were made on calm days, wind could also be a potential fac-
tor affecting the distance moved.
Once they invade an area, D. abbreviatus populations probably tend to
disperse rather slowly. Major modes of dispersal could involve a series
of short flights or mechanical transport during shipment of plants, on fruit-
hauling trucks, and on grove machinery. This hypothesis is supported by:
(1) our observations on the locations of weevil-infested groves within a
quarantine area; (2) the distance separating the 2 quarantine areas; (3) find-
ing immatures in the soil of plants shipped to other areas; and (4) finding
adults clinging to tractors used in infested groves.

POTENTIAL OF RESISTANT CORN TO REDUCE CORN EAR-
WORM PRODUCTION-(Note). Resistance in corn, Zea mays L., to corn
earworm, Heliothis zea (Boddie), has been known for many years (W. W.
McMillian and B. R. Wiseman, Fla. Agr. Exp. Sta. Monogr. Ser. 2., 1972,
131 p). Wiseman et al. (J. Econ. Ent. 1972, 65:835-7) described one of the
mechanisms of resistance in 2 corns ('Dixie 18' and '471-U6 X 81-1') to be
tolerance. They also reported (Fla. Ent., 1976, 59:305-8) that the resistance
of 'Zapalote Chico #2451' was either antibiosis and/or nonpreference. Wise-
man et al. (Fla. Ent., 1977, 60:97-103) delineated the physical character-
istics of the 3 resistant corns and later studied the behavior of the corn
earworm larvae on the resistant and susceptible corns (Wiseman et al., in
press).
Dahms (M. G. Jotwani and W. R. Young (Eds.) Control of the Shoot-
fly, 1972, p. 152-167) explained the theoretical role of host plant resistance
in an integrated insect control program, demonstrating the direct and in-
direct value of all 3 mechanisms of resistance (nonpreference, antibiosis,
and tolerance), and giving examples of how resistant varieties reduced in-
sect populations. Schalk and Ratcliff (Bull. Ent. Soc. Amer., 1976, 22:7-10)
recently reported in an evaluation of programs of the Science and Educa-
tion Administration (USDA) that the use of insect-resistant cultivars has
been successful in controlling insect pests and in reducing the use of insecti-
cide. They were unable to find evidence showing reduction of earworms when
resistant corn cultivars were used. Hence this study involves a resistant
corn, Zapalote Chico #2451 and its impact on the potential population
buildup of corn earworm.
Two corn entries, Zapalote Chico #2451 (resistant) and White Cross
Bantam sweet corn (susceptible), were planted alternately in halves of
three 30 X 100-ft cages for each of 2 years, 1975-76, and in 2 cages in 1977.
At full silk (2 days past initial silk), 1 corn earworm first-instar larva
was placed on each silk, and the number of emergence holes was counted
21 days later to indicate the survival or impact of each corn entry on ear-
worm buildup. An average of 780 and 1060 plants of Zapalote Chico #2451
and White Cross Bantam, respectively, were infested each year.
In 1975, emergence holes were found in 91% of the White Cross Bantam
sweet corn ears and in 27% of the Zapalote Chico #2451 ears. In 1976,
even though the apparent corn earworm establishment was low for White
Cross Bantam, it still produced 3 times as many corn earworms as Zapalote
Chico #2451. In 1977, however, emergence holes were found in 77% of the
White Cross Bantam ears and in only 12% of the Zapalote Chico #2451.
Only 16% of the ears of Zapalote Chico #2451 produced corn earworms
over the 3-year period, whereas 66% of the White Cross Bantam ears had
emergence holes. This finding agrees with earlier data by the authors (J.
Econ. Ent. 1972, 65:835-7) in which ca. 70% of the susceptible 'Ioana' and
intermediate '409 x 20' ears were infested with corn earworms. Therefore,
the resistance of Zapalote Chico #2451 did affect the establishment and
the sustained level of the corn earworm. If we can approach this level of
resistance in the commercial corn hybrids, corn earworm problems may be
greatly decreased.-B. R. Wiseman, W. W. McMillian, and N. W. Widstrom,

INFLUENCE OF HYDROPRENE ON CARIBBEAN FRUIT
FLY1 SUITABILITY FOR PARASITE DEVELOPMENT2

P. O. LAWRENCE3, P. D. GREANY4, J. L. NATION5, AND H. OBERLANDER4

ABSTRACT
Onset of the critical period (with respect to pupation) for larvae of
Anastrepha suspense (Loew) was associated with decreased success in para-
sitization by the endoparasite, Biosteres (= Opius) longicaudatus Ashmead.
A significantly greater proportion of adults emerged from hosts parasitized
during the pre-critical period (94.1%) than from hosts parasitized during the
post-critical period (48.1%). Parasite emergence increased to 60.5% in host
larvae treated early in the 3rd instar with the insect growth regulator hy-
droprene and parasitized 2 days later, when they would otherwise be beyond
the critical period. Non-parasitized controls treated similarly with hydro-
prene pupated ca. 1 day later than usual, indicating that hydroprene de-
layed the onset of the critical period. The duration of the parasite egg stage
was 2.0 days in pre-critical period hosts and 4.1 days in post-critical period
hosts. Parasite egg duration in hydroprene-treated hosts was also 2.0 days.


Biosteres (Opius) longicaudatus Ashmead was introduced into Florida
in 1969 for control of the Caribbean fruit fly, Anastrepha suspense (Loew)
(Baranowski and Swanson 1971). Studies on the host-parasite relationship
were initiated to improve the efficiency of mass-rearing efforts intended to
supply parasites for field releases. During these studies Lawrence et al.
(1976) found that 5-day-old A. suspense larvae which were in the 1st day of
the 3rd instar were more suitable for parasite development than were 7-
day-old larvae (late 3rd instar) that were about to pupate. In many insect
species, the amount of juvenile hormone relative to ecdysone (the growth
and maturation hormone) decreases with increased age (Schooley et al.
1976). The period during which the amount of ecdysone exceeds that of ju-
venile hormone and achieves a level sufficient to initiate pupation, is re-
ferred to as the critical period (DeBach 1939). Thus, the observed change in
suitability with increased age of A. suspense larvae suggested possible en-
docrine involvement. Endocrine influences on host suitability have been
demonstrated in other host-parasite systems (Bradley and Arbuthnot 1938,
Cals-Usciati 1969, 1975, Smilowitz and Iwantsch 1973, and Smilowitz 1974).
Nenon (1972a,b) has also demonstrated that juvenile hormone and ecdy-
sone influenced the survival of embryos and larvae of an Ageniaspis spe-
cies under in vitro rearing conditions. The subject of host hormone influ-
ences on insect parasites was recently reviewed by Riddiford (1975).
The objective of the present study was to relate physiological events
occurring during maturation of 3rd (last) instar larvae of A. suspense to
their suitability for development of the parasite B. longicaudatus. The

onset of the critical period was determined as an indicator of larval ma-
turity. Success in parasitization of pre and post-critical period larvae was
evaluated. Since changes in the juvenile hormone titer are known to occur
concomitant with the onset of the critical period and host maturation (Rid-
diford 1975), we also evaluated juvenile hormone influences on host suit-
ability for successful parasite development. In the absence of authentic
host juvenile hormone, hydroprene (ethyl-3,7,11-trimethyl-2,4-dodeca-
dienoate), an insect growth regulator that mimics juvenile hormone (Staal
1975) was applied to host larvae to influence host suitability. Since earlier
work on this host-parasite system (Lawrence et al. 1976) showed that B.
longicaudatus emergence and duration of the egg stage were influenced by
the age of host larvae, these 2 factors were compared in untreated and hy-
droprene-treated hosts.

MATERIALS AND METHODS
Cultures of A. suspense and B. longicaudatus were maintained as de-
scribed by Lawrence et al. (1976) and Greany et al. (1976). Tests were con-
ducted at 26 + 20C and 60 + 5% RH under a 14:10 L:D regimen.

Determination of the Critical Period in A. suspense Larvae
About 54 A. suspense larvae (3 replicates of 14-18 larvae each) were
ligated with surgical thread posterior to the ring gland on each of the 1st
two days of the 3rd instar. Larvae were 5 and 6 days old, respectively. Simi-
lar numbers of unligated larvae of corresponding ages were used to com-
pare pupation times. Larvae were observed at least twice per day for 3 days
to count those that had pupated. Ideally, larvae ligated posterior to the
ring gland before the critical period should pupate only anterior to the
ligature while those ligated after the critical period should pupate both
posterior and anterior to the ligation (Debach 1939). These criteria were
used to determine the critical period of A. suspense.

Effect of Host Maturity and Hydroprene Treatment
on Successful Parasite Development
Each A. suspense larva was topically treated with 2 ul of an acetone-
hydroprene solution that provided 2.8 ug active hydroprene/g of larval
weight. Applications were made twice, on the 1st day of the 3rd instar (5
days old) and again 12-15 h later. This technique was used to maintain host
hormone levels despite possible enzymatic inactivation, as noted by Gil-
bert and Schneiderman (1958) for other species. No deleterious effects due to
solvent applications were observed in the controls. All larvae were anaes-
thetized with CO, for 2 min prior to treatment.
Two groups of larvae were utilized. These consisted of hydroprene-
treated larvae and their untreated counterparts. Each group initially con-
sisted of 3 replicates of 130-190 larvae per replicate. From each of these
groups, 50-80 larvae per replicate were removed to determine time of pu-
pation. When the remaining larvae in both groups were 7 days old, they
were exposed for 24 h to 5 to 6-day-old female parasites at a host: parasite
ratio of 30:1. A third group of untreated 5-day-old larvae was parasitized
similarly to facilitate comparison of data from untreated 5-day-old and

7-day-old larvae with data from hydroprene-treated individuals. A total
of 52,131, and 58 parasitized larvae were removed at random from the un-
treated 5-day-old, 7-day-old and hydroprene-treated groups, respectively.
These samples were dissected to determine the duration of the parasite egg
stage. We determined earlier that a host:parasite ratio of 30:1 usually re-
sulted in 1 parasite egg/host. Only those 1st instar parasites that were lo-
cated were used to determine egg duration. The latter was based on the oc-
currence of 1st instars in samples taken 0-8 days after parasitization. Re-
maining hosts were held for up to 21 days after parasitization for emergence
of adult parasites.

RESULTS
Determination of the Critical Period of A. suspense Larvae
The results (Table 1) indicate that the critical period occurred during
the 6th day of development for most of the A. suspense larvae observed.
The data indicate that 5-day-old larvae were in the pre-critical period stage,
while 7-day-old larvae were in the post-critical period stage. Lawrence et
al. (1976) noted a decline in the suitability of A. suspense larvae for de-
velopment of B. longicaudatus when hosts were older than 5 days. These
data correlate well with the onset of the critical period.

on Successful Parasite Development
The data in Table 2 show that the suitability of untreated A. suspense
larvae was related to their maturity at the time of parasitization. Parasite

period host larvae (Table 2). These data are in agreement with the findings
of Lawrence et al. (1976).
Most of the hydroprene-treated larvae pupated when they were 8 days
old while the majority of untreated larvae pupated at 7 days of age (Fig.
1). Hydroprene treatment also affected parasite emergence and the duration
of the parasite egg stage in treated hosts (Table 2). The mean duration of the
parasite egg stage was the same in hydroprene-treated larvae and untreated
5-day-old, pre-critical period larvae, but was significantly (P< 0.05) longer
in untreated 7-day-old, post-critical period hosts (Table 2). Dissections re-
vealed that hydroprene-treatment did not affect acceptance of hosts for
parasitization, as equivalent numbers of parasite eggs were found in treated
and untreated parasitized hosts. Thus, hydroprene-treated hosts were more
suitable for egg development than were untreated, 7-day-old, post-critical
period larvae.
Comparison of mean parasite emergence rates from untreated 7-day-old
hosts and hydroprene-treated 7-day-old hosts showed that hydroprene treat-
ment improved parasite emergence from 48.1% in the former to 60.5% in the
latter (Table 2). However, untreated 5-day-old larvae were still the most
suitable of all hosts used in the experiment, yielding 94.1% emergence
(Table 2).

DISCUSSION
These studies show that the onset of the critical period coincided with
decreased host suitability for parasite development. The latter may be re-
lated to hormonal, nutritional or other host mechanisms. Although hor-
mone levels in the host were not measured, it is significant that hydroprene-
treated larvae took longer to pupate than untreated controls and yielded
parasite egg duration and adult emergence results similar to those observed
in young, pre-critical period larvae. Normally, pre-critical period larvae

of many insect species have a relatively high juvenile hormone content
(Schooley et al. 1976). We do not know whether hydroprene treatment al-
tered juvenile hormone levels of the larvae. The improvement in parasite
emergence due to hydroprene treatment may be attributable to increased
egg hatch (Lawrence et al. 1976, observed < 50% egg hatch in untreated 7-
day-old hosts) concomitant with the normalization of parasite egg develop-
ment times. Although treatment of the host with hydroprene affected para-
site development, it is not yet known whether the host's own juvenile titer
in the hemolymph at the time of parasitization is critical for proper devel-
opment of the parasite. The mechanisms by which hydroprene or host hor-
mones affect the parasite's development deserve further investigation. Since
Nenon (1972a,b) observed that juvenile hormone and ecdysone are impor-
tant for embryo development of certain parasitic species, in vitro studies
might be useful in elucidating the role of hormones and the times during

EGGS AND OVIPOSITION OF THE STICK INSECT PARA-
BACILLUS COLORADUS (PHASMATODEA: HETERONEMII-
DAE)-(Note). The eggs of Phasmatodea have historically attracted in-
terest by their bizarre shapes and alleged seed mimicry. Oviposition in
most species is simply the dropping of single eggs in a seemingly random
manner, or propelling them some distance by a flick of the abdomen,
although several species glue their eggs to substrates (Bedford, 1978, Ann.
Rev. Ent. 23:125-49). In Parabacillus coloradus, egg laying is atypical and
egg form unusual.
Three female nymphs were obtained from the arid grasslands of Berna-
lillo Co., New Mexico, and raised to maturity in the laboratory (in the
absence of males) on the foliage of the shrub Dalea scoparia (Leguminosae).
Eggs are relatively large, e.g., those produced by a 55 mm female av-
eraged 6.2 mm by 1.2 mm, and gray shading to white in the region of the
micropylar plate. General appearance is similar to a smooth fusiform grass
seed. (Nymphs and adults can be found on grasses as well as herbs and
shrubs.) Oviposition occurred at night.
Eggs were frequently found lodged in the wire cage screening. Accidental
insertion is improbable. Eggs in the screening and those on the cage floor
often had an adhesive on them that made removal without rupture difficult.
After 3 months, 1 of 14 eggs kept indoors in a closed petri dish hatched,
demonstrating "accidental" parthenogenesis, a common phenomenon in the
Phasmatodea (Bergerard, 1962, Endeavour 21:137-43).
A female with 2 eggs adhering to the abdominal tip is deposited in the

REPORT OF THE ENTOMOLOGY IN ACTION COMMITTEE
The Entomology in Action slides were used by only 2 individuals this
past year: by Dr. David Reed, Vincennes, Indiana and Dr. Daniel Wojcik,
Gainesville, Florida.
The Committee used the slides and the Caramate projector at the 1977
meeting of The Florida Entomological Society. The slide presentation and
the 2 exhibits of Biological Control and Entomology in Florida were on
display in the mezzanine of the Cape Coral Country Club Inn.
The slides, Caramate projector, and exhibits are available for use by
any member for presentation before any type of group. In addition to the pre-
pared slide presentation, the Committee plans to develop a set of slides
depicting insects in natural settings. These types of slides interspersed in
an informal presentation create much more interest especially among
children. If anyone can donate duplicates of such slides to the Committee,
we will catalogue them so that they may be used by the membership.

The exhibits and slides will be displayed at the Southeastern Branch
Meeting in January 1978. If anyone wishes to add a display for that meeting
please contact Frank Mead or any member of the Committee.

NECROLOGY REPORT
Dr. Mohammad G. Rabbani (1945-1977). On 2 February he died at
Manaus, Brasil of acute renal failure following a severe infection of mixed
Plasmodium falciparum and P. vivax The infection was acquired while he
was doing research on Anopheles darlingi for the Instituto Nacional de
Pesquisas da Amazonia. He would have been 32 on the 15th of March. He
was a native of Bangladesh. In 1974 he obtained his Ph.D. at the University
of Illinois under the direction of Prof. J. B. Kitzmiller. Mosquito cyto-
genetics was his field of specialization, and he was considered an outstand-
ing researcher and teacher. Obituaries have been published in the June 1977
issue of the Florida Entomologist 60(2):96 and the June 1977 issue of Mos-
quito News 37(2):308.
Dr. Milledge Murphey (1912-1977). On 15 February he died from leu-
kemia at the age of 64. He was a native of Georgia and had been a Professor
of Entomology at the University of Florida, Gainesville, for 30 years. Nu-
merous awards and honors had come his way. He was a Past President of

while visiting friends in Vincennes, Indiana. Dr. Steiner was especially well
known for his knowledge of fruit flies developed when he was Leader of
the USDA Hawaiian Fruit Flies Laboratory. Techniques based upon his
research were used to eradicate the Mediterranean fruit fly in Florida
and Texas and have been adapted for world-wide applications. He was a
native of Ohio and in 1967 received an honorary Doctor of Science degree
from Ohio State University, his Alma Mater. For further information see

REPORT OF THE PUBLIC RELATIONS COMMITTEE
This report is given by the Public Relations Committee whose primary
responsibilities are to promote the Florida Entomological Society and the
profession of entomology.
One prime activity of the Committee during 1977 was to survey the
members concerning their efforts in public relations. A 2-page questionnaire
was sent to the entire Florida membership for this purpose. Our first as-
sessment of the 1977 questionnaires indicates a wide range of promotional
efforts. The 1976 questionnaires have been analyzed and results from both
years will be published soon in The Florida Entomologist.

CERTIFICATES OF APPRECIATION
For the Certificate of Appreciation, this year we depart from the usual in
that tonight we express Society Appreciation not to an individual, but to a
couple. This couple, displaced from New Jersey to Florida about 1966, has
contributed to numerous Society functions in many ways. They have served
separately as well as together on various committees and have for the 2
past years worked tirelessly on local arrangements to perfect every de-
tail of our Society meeting. Their work in the Society has earned for them
this recognition.
The Honors and Awards Committee presents this Certificate of Apprecia-
tion which reads, "To Daniel and Bernie Wojcik for services rendered in
the field of Entomology" (Fig. 2).

REPORT OF THE STUDENT PAPERS AWARDS COMMITTEE
(Report and presentations were made at the banquet)
In this year's competition there were 9 papers submitted by student au-
thors. The Committee commends these students for their efforts.
Before reviewing the prizes and this year's winners, I would like to out-
line the procedure that committee members followed. In early August,
2 general information sheets and a copy of the judging form were mailed
to each competitor; these items were intended to help in the student's final
preparation for his presentation. The sheet that was returned to the judges
was not only a confirmation of the student's interest in competition but
also an update on his current mailing address. The student's presentation
was independently judged by the 3 committee members; points were awarded
for organization, delivery, and poise. The total points for each student were

tallied after competition and the top 3 scores were awarded prizes. Again
this year we plan to mail each student his scores as well as a summary of
his competitors' scores. We hope these scores and comments will be useful
to the student in preparation for later presentations.
The prizes are supposed to be used by the student for purchasing books
and supplies useful to his research. We thank "Industry" for contributing
the following prize money.
FIRST PRIZE $50.00
SECOND PRIZE $30.00
THIRD PRIZE $20.00
The winners in this year's competition are:
THIRD PRIZE: T. H. Atkinson, "Pheromone baited live traps for sampling
southern pine beetle adult populations to estimate the incidence of selected
pathogens."
SECOND PRIZE: M. A. Altieri. "Insect prevalence in maize (Zea mays)
and bean (Phaseolus vulgaris) polyculture systems in tropical Colombia."
FIRST PRIZE: G. Dodson and C. Kleyla. "A field study on the calling
behavior of mole crickets."
Congratulations to these winners and thanks again to all of those who
competed.
