Four new species of Hypoaspis (Laelaspis) are described and illus-
trated. These are: H. moseri from a laboratory culture of Anuroyryllus
muticus (DeGeer), Louisiana; H. picketti from citrus litter, Florida; H.
johnieae from sand pine litter, Florida; and H. mumai from citrus and
sand pine litter, Florida. Thirteen identifiable species are now known
from North America and Mexico. A key to the females of these species
is included.

Evans and Till (1966) list Laelaspis Berlese, 1903, as one of nine
subgenera of Hypoaspis Canestrini. The Hypoaspis mites from the nearc-
tic, tropical and subtropical regions have not been studied as thoroughly
as those from the palaearctic regions of the world. Collection and
study of species from these areas are needed to clarify the status of these
subgenera. Although we feel the subgeneric placement of some of the
Hypoaspis groups may be tentative, we are following the classification
proposed by Evans and Till (1966) and considering Laelaspis as a sub-
genus of Hypoaspis.

Nine species of Hypoaspis (Laelaspis) have been recorded from North
and Central America (Hunter 1961 and 1964, Hunter and Davis 1962).
Seven species have been taken from or in association with ants, a total of
six known genera of ants being represented. To date only two mite
species, pauli Hunter and Davis from Georgia and brevichelis Hunter from
Kansas, have been recorded from the same ant genus-Crematogaster.
Other ant genera from which Laelaspis mites have been collected are:
Aphaenogaster, Myrmica, Eciton, Neivamyrmex, and Iridomyrmex. To
date piloscutuli Hunter is the only species reported from two genera of
ants (see Hunter 1961). Two mite species have been recorded from non-
ant associations; these are longipilis Hunter from a lumber foundation
and lundi Hunter from Polianthes bulbs. We have taken vitzthumi, one of
the more commonly collected species in Georgia, from numerous Berlese
samples of litter containing ants, but a definite ant association has not
been made at this time.

Four new species are described below bringing the total number of
identifiable species from North America to 13. A key is given to females
of known species.

muticus (DeGreer). All specimens with same data. Holotype, female
paratype and 2 male paratypes USNM; female, male and deutonymph
paratypes USFS; remaining type material UG.
COMMENTS. Superficially this species is similar to vitzthumi (Womer-
sley), particularly in the type of dorsal setae. The female of the new

70 The Florida Entomologist Vol. 51, No. 2

species is readily separated from vitzthumi by the genito-ventral plate,
the exopodal plate and the relative length of the peritremal compared to
the exopodal plate (see key above and Fig. 21). Reticulation of the
genito-ventral plate of the two species is also distinct. The males are
readily separated by the chelicerae and the spermodactyl. In vitzthumi
the spermodactyl curves towards the fixed digit apically, rather than
away as in the new species and the movable digit is apparently endentate.
The leg setae of the new species are distinctly heavier than in vitzthumi.

Hypoaspis (Laelaspis) johnieae n. sp.
Fig. 3A-C
This species, known only from the female, is distinct in having no
dorsal or ventral pilose setae and in having the median dorsal plate
setae, including J5, with a small lateral knob just above the setal base.
FEMALE. Shape oval, evenly rounded anteriorly and posteriorly. Dor-
sum. Fig. 3A. Dorsal plate (525u X 364g-average of 4 specimens)
covering all of dorsum; surface bearing reticulations as illustrated; dorsal
plate bearing 39 pairs of setae plus 3 unpaired setae between J rows; one

Roland F. Hussey. 1896-1967. Photo by Frank W. Mead, Div. Plant
Industry, Fla. Dept. Agr.


To me has come the sad duty of making known the death of Roland
Fountain Hussey, my good friend. Although his eyesight was begin-
ning to fail, his death was sudden. He died of a heart attack at his home
in Gainesville on the 19th of August, just at the time of his retirement
from teaching and at the very beginning of his long-awaited opportunity
to devote his fulltime to research on Hemiptera.
Born in San Francisco, California, 16 November 1896, Dr. Hussey first
attended the University of Michigan in 1915 where he earned his A. B.
degree in 1918. He thcn did graduate work at the University of Minne-
sota (1918-1920), but later earned his M. S. degree (1921) and Sc. D.
(1923) at Harvard University, each with a major interest in Entomology.
Upon graduation, Dr. Hussey accepted an appointment as Instructor in
Biology at New York University (Washington Square College) where he
remained until 1926.
During these early years as student and teacher he maintained an
active interest in the taxonomy of Hemiptera and published regularly

but in 1926 he left the academic field and for the next 20 years held real
estate and mortgage management positions with the New York Academy
of Medicine and various administrative positions with Doctors Hospital.
The only relief from his duties during these years was an entomological
reconnaissance in Paraguay during the Summer of 1931-32. He published
little during this period but outstanding is his monograph of the family
Pyrrhocoridae which appeared in 1929 as Fascicle 3 of the General
Catalogue of Hemiptera.
In 1947, he married the genial and sociable Karlene Cozart and
accepted a teaching position at Florida Southern College at Lakeland.
Then began the happiest and most productive period of his life. He was
back in his element of teaching and research. At this time he began the
monumental task of bringing the Van Duzee Catalogue of American
Hemiptera up to date and extending coverage to all of the Americas.
In 1953 he accepted a position as Assistant Professor with the Depart-
ment of Biology at the University of Florida and rose to Professor of Bi-
ology, Professor of Biological Sciences and Professor of Entomology. He
was justly proud that he was to have been retired Professor Emeritus of
Biology, the first in the history of the University of Florida.
Dr. Hussey was Associate Curator of Insects at the University of
Michigan Museum of Zoology during the summers of 1950, 1952, 1953, and
1956. He was a member of Sigma Xi, Entomological Society of America,
Entomological Society of Washington, Florida Entomological Society,
and Kansas Entomological Society; formerly, when he was resident in
the respective areas, he was a member of the Cambridge (Mass.)
Entomological Club, New York Entomological Society, and the Brooklyn
Entomological Society. For the last 10 years he was Editor of the
Annals of the Entomological Society of America.
Roland was a quiet man with great tolerance for the views of others,
yet he stated his own opinions forcefully and clearly. His unassuming
demeanor was sometimes mistaken for aloofness when actually he was a
most heartwarming gentleman. He was always ready to help his col-
leagues untangle a taxonomic problem or to collaborate on a research
Project. As a guest in his home, I soon discovered that he was very
fond of cats, classical music, and conversation. He had a keen sense of
humor and almost always had a new anecdote to tell.
His research was carried out with great enthusiasm and thorough-
ness. He wrote few extensive articles and seldom attempted comprehen-
sive monographic treatments, probably because he lacked continuous spare
time. He chose his subjects well and rarely failed to make some definite
and essential contribution. He published 58 papers, many dealing with
his favorite group, the aquatic and semi-aquatic Hemiptera.
It is indeed unfortunate that Roland left unfinished what would have
been undoubtedly his greatest contribution, a catalogue of the Heteroptera
of the Americas. At Mrs. Hussey's request, I have assumed the responsi-
bility of maintaining this uncompleted work and have agreed to make an
effort to complete it. According to Dr. Hussey's own wishes, his excellent
Hemiptera collection has been deposited in the Museum of Zoology at
the University of Michigan. Mrs. Hussey has given his fine library to the
University of Florida.
In addition to his wife Karlene, Roland is survived by two sons and
two daughters by two former marriages.

The use of sterile males to control a cage population of a laboratory
strain of Anopheles quadrimaculatus was not successful, even though 80
to 90% of the females laid sterile egg clutches. At the ratio of sterile
males to normal males being used, complete sterility should have been
quickly achieved. Subsequent studies of the survival and sexual vigor of
these sterile males indicated that only a small number, about 5%, of the
released males were actually competing with normal males for the unin-
seminated females. Thus, until a more hardy and sexually vigorous male
A. quadrimaculatus can be reared in the laboratory, the use of the
sterile-male technique to control this insect seems impractical.

Research was begun several years ago to adapt the technique of
releasing sterile males to the control or eradication of mosquitoes. Davis
et al. (1959) showed that doses of 8,865 to 12,000 R applied in the adult
or pupal stage caused complete sterility in males and females of Anopheles
quadrimaculatus Say. However, in the laboratory, males sterilized by
gamma irradiation were not as competitive as normal males in inseminat-
ing females, although at high ratios of sterile to fertile males (6:1 and
10:1) production of viable eggs decreased more than 80%. In contrast,
Weidhaas et al. (1962) were unsuccessful in either suppressing natural
populations of A. quadrimaculatus or in causing a significant degree of
sterility in wild females by the release of males sterilized by gamma
irradiation. Also, when Dame et al. (1964) studied the behavior of
released sterile A. quadrimaculatus from the laboratory colony and that
of wild mosquitoes in the field, they concluded that the behavioral de-
ficiencies of colony males prevented them from effective sexual competition
for wild females though they were capable of mating effectively with
released colony females.
To gain a better insight into the problems associated with the release
of sterile male mosquitoes, we decided to release sterile males into a
population of A. quadrimaculatus breeding in a large outdoor cage. By
using the caged population, we could study both the efficacy of the
induced sterility and also the behavior and survival of a strain exposed
to semi-natural conditions. The regular Gainesville laboratory colony of
A. quadrimaculatus was used as a source of the sterile males and to
start the cage population since it was difficult to establish a wild strain
in the cage (several attempts had little success).


The cage used for the experiment was 40 x 16 ft, and 12 ft high, and
consisted of an aluminum frame covered by 20-mesh plastic screen. It

78 The Florida Entomologist Vol. 51, No. 2

was located in a wooded area near the Insects Affecting Man Laboratory,
Entomology Research Division, Agricultural Research Service, U. S. De-
partment of Agriculture, Gainesville, Florida. A wooden shed, 12 x 8 ft by
7 ft high, was built within the cage, and a calf stabled in this shed
throughout the experiment as a blood source for the female mosquitoes.
The shed also served as the main resting area for engorged females,
which made it relatively easy to estimate the adult female population.
Cotton pads soaked in honey and water were placed in the cage and
changed weekly to provide nutrient for the males. Also, 2 plastic-lined
ponds (5 x 6 x 2/3 ft), a stainless steel tank (4 x 3 x 2/3 ft), and three
wooden trays (3 2/3 x 1 1/2 x 1/4 ft) filled with water were installed
to serve as oviposition and breeding sites. In addition, about 2 inches
of soil was put on the bottom of each of the two plastic-lined ponds, and
about five clumps of grasses and reeds obtained from a nearby swamp
were planted in the soil. A small amount of soil and leaves was added
periodically to the stainless steel tank to act as infusion media in the tap
water. Although the females readily laid eggs in these containers, larval
development was poor. Therefore, periodically throughout the experiment,
a mixture of dried liver extract and brewer's yeast was added to the ponds
with the daily supplement of finely ground laboratory chow. Despite
this, larval production remained so poor that only about 1% of the
progeny from these eggs ever reached adulthood. It became apparent
after 2 months that the colony strain of A. quadrimaculatus could not
maintain itself at a high level under these conditions. Moreover, the
number of larvae decreased after the first few generations, indicating
that something was being depleted from the water or that unfavorable
elements were accumulating that prevented development.
To increase production, we set the three wooden trays on a rack under
a leanto on the back side of the calf shed and added distilled water infused
with liver extract and yeast. The female mosquitoes rarely oviposited in
these trays, but larvae placed in them developed readily with little
mortality. As the larvae matured, finely ground laboratory chow was
sprinkled on the surface of the water as a supplemental food source.
The trays had several advantages over the ponds, among them the in-
creased production of adult mosquitoes and the ease with which pupae
could be counted; also, these pupal counts permitted us to make a more
accurate estimate of the daily adult emergence. The trays could be
easily washed, and, since they were set up at staggered intervals, they
could be cleaned after each generation and set up again without greatly
interfering with overall adult production. Therefore, the best method of
achieving a workable population of A. quadrimaculatus for this study was
to use the two plastic-lined ponds and the stainless steel tank primarily
for egg deposition and the trays for rearing the larvae to adults. We
gathered the eggs daily by using a common water dipper (running it along
the rim of the ponds and tank) and then transferred them to the trays.
As noted, the laboratory colony of A. quadrimaculatus also served as
the source of sterile males for release in the cage. These larvae were
reared on a diet of dried liver extract, brewer's yeast, and finely ground
Purina laboratory chow. The pupae were held in waxed paper cups in
cages, and cotton soaked in a 2.5% sugar solution provided food for the

Patterson: Control by Use of Sterile Male Mosquitoes 79

emerging adults. Two days after emergence, these mosquitoes were in-
activated in a cold room and sexed, and the males were sterilized by dust-
ing with apholate. The dusting was accomplished by placing about 100
males in an 8-oz waxed paper cup and sprinkling about 1 g technical
apholate over them. The cup was gently rotated at an angle to insure an
even distribution of the material on all the insects, and then removed from
the cold room and placed in a small cage in a room at 85F and 60 relative
humidity. Once the males had recovered, a cup containing a 2.5% sugar
solution on cotton was placed in the cage. The sterilized males were held
in the laboratory for 24 hr to check for any excessive mortality. Nor-
mally little mortality occurred.
The releases of the sterilized males were usually made daily in the
late afternoon. First the cloth sleeve of the small cage was turned back,
and the waxed paper cups containing the technical apholate and the sugar
solution were removed. Then the cage was placed just above the rearing
trays under the leanto. By morning, all the live males had left the
smaller cage and migrated to resting areas around the calf shed. Gen-
eral observations on total numbers of males present at any given time in
the cage indicated that the majority probably did not survive more than
2 to 3 days. Since these sterile males were 3 days old at the time of
release and were released near newly emerging females, they should have
had ample opportunity to mate.
Population estimates were made by daily counts of all engorged rest-
ing females and pupae present in the rearing trays. The three ponds
normally averaged 20 pupae per day throughout the experiment; however,
pupae were extremely difficult to locate in the ponds. The ratio of sterile
to nonsterile males was established each day from the count of pupae
divided by four (about 48 hr is required for pupae to mature and half
the newly emerging adults are females).
Weekly, as many as 3 dozen engorged females were taken from the
calf shed with an aspirator and placed individually in 10-dram vials con-
taining 5 ml of distilled water. A waxed paper ring about 1/8 in. wide
and the same diameter as the vial was floated on the water surface to
prevent surface tension from pulling the eggs up the sides of the vial
where they would dessicate. After a week, the percentage of hatched eggs
was determined. As a check on the handling procedures, engorged fe-
males obtained from the laboratory colony were placed in vials, and the
viability of their eggs was determined in the same manner. Also, peri-
odically throughout the program, sterile males were removed from the
holding cage and placed with control virgin females. After 4 days, these
females were blooded on a guinea pig, and their eggs were also assayed
for sterility.
As noted previously, most males survived only a few days, but no
facilities were available to evaluate the effect of this factor on the results.
In addition, the experiment had to be discontinued before it was com-
pleted because of cold weather. We therefore found it advisable to
develop a technique for determining the actual longevity of the sterilized,
released males at comparable conditions. Twelve outdoor cages, 4 x 8 x
6 ft, were each stocked with 100 three-day-old sterile males and 50 three-
day-old virgin females from the laboratory colony of A. quadrimaculatus.

80 The Florida Entomologist Vol. 51, No. 2

Each cage contained a black resting box, 2.5% sugar solution, and a pan
of water. After 24, 48, and 72 hr, all the live mosquitoes were collected
with a small hand battery aspirator from four cages, the number was
recorded, and the females were dissected and their spermathecae were
checked for sperm, indication of successful insemination.

Table 1 summarizes the data. So many outside factors obviously
affected the population that it was almost impossible to evaluate suppres-
sion of the population (short of almost complete eradication). Any vari-
ation in the care and handling, for example, the number of eggs trans-
ferred to the trays or the amount of food used, influenced the number of
larvae that survived. Also, the test was conducted during September and
October, and the cool weather undoubtedly affected the survival of the
adults. The removal of as many as 3 dozen females each week from a
fairly small population may have influenced the size of the total popula-
tion, especially since complete sterility was never nearly achieved for any
length of time. Thus, the number of females that laid sterile egg batches
was the only true indication of the effectiveness of the sterile males, but
because the method of inducing sterility was not always 100% effective,
the percentage of sterile females could only be based on the number of
females laying normal free-floating egg clutches in which less than 10% of
the eggs hatched. Many clutches from sterile females contained fewer
eggs than the nonsterile clutches.
Between the second and fifth weeks of the test while the ratio of
sterile to nonsterile males ranged from 10:1 to as much as 40:1, the
percentage of females that laid sterile eggs ranged from 40 to 65. For
the first 2 weeks after the ratio was increased to 100:1, the percentage
remained about the same (62 to 67%), but the last 3 weeks of the test, it
increased to better than 80%. At the release rate of 100:1, the theoretical
number of sterile females should have been 99% if the sterile males had
been competing favorably. Obviously they were not, even though they
were sexually mature at the time of release (3 days old). Indeed, at this
rate, even if only half the released males were competing adequately,
almost all the egg clutches should have been sterile.
No positive explanation of the results can be offered, but the male
survival tests conducted after the release experiment indicate that the
lack of hardiness of the colony-reared males is the logical cause. In these
survival tests, only 50% of the males and 78% of females survived 24 hr,
7% of the males and 48% of the females survived 48 hr, and less than 1%
of the males and 4% of the females survived 72 hr. After 24 hr. only 3%
of the surviving females were inseminated. Then since only 7% of the males
were surviving after 48 hr and less than 1% after 72 hr, the number of
additional females that could have been inseminated was low. If we
assume a value of 5% insemination, only 5% of the males released in the
cage could have been competitive with normal males. The theoretical
ratios of sterile:nonsterile males based on this figure have been computed
and are reported in the table. The degree of sterility obtained (based on
these figures) was close to the theoretical value (83% theoretical vs. 80 to

90% actual during the last 3 weeks of the experiment when the ratio of
sterile to nonsterile males was 5:1).
A check cage of sterile males and nonsterile female mosquitoes was
held in the laboratory for 3 days while the survival tests were made. Of
these, 69% of the sterile males survived for 3 days and 82% of the females.
Thus, the poor survival in the outdoor cages was undoubtedly caused by
the rearing conditions for the larvae in the laboratory and the handling
of the adults before they were placed in the outdoor environment.
Tests made during the experiment to verify the effectiveness of the
apholate treatment showed that more than 97% of the females mated to
apholate-dusted males laid sterile egg masses. Natural sterility in fe-
males from the laboratory colony was checked each week and found to
range from 0 to 33% with an average of 8%.

Eggs of the Geometridae have very few features typical of all species.
The great majority are oval in shape and deposited on their sides. The
eggs of a few species are vertical or at a 45' angle when deposited in
clusters. As a rule they are not spherical or cone shaped as in Arctiidae
and Notodontidae, or distinctly depressed and scale lke with radiating
ridges as in Noctuidae, or very flat overlapping masses as in Pyralidae
and Tortricidae. One fact of significance is that eggs of species in a given
genus usually resemble each other rather closely.

This report is a continuation of a study on some eggs of moths among
the Geometridae presented in The Florida Entomologist, 1962, volume 45,
pages 109-17. Since that date eggs from many additional species of
geometrids have been seen. Most of them are presented in this publica-
The great majority of the eggs of the geometrids in this study came
from females caught at "black lights" adjacent to a white cloth or in
traps with a "black light" suspended over a metal funnel inserted in the
top of a screened walking cage or a screen covered, box-like container.
The captured females were placed in polyethylene or paper bags or in
polyethylene lined glass containers where they deposited their eggs on the
polyethylene, paper, foliage, bark, or other objects placed in the deposition
The following is a review of all eggs of the Geometridae seen to date.
All references to figures reported on in 1962 will have a 62 before each
numeral. The figures of the species and their descriptions are arranged
in the same sequence as that found in J. McDunnough's 1938. Checklist
of the Lepidoptera of Canada and the United States of America, Part 1,
Macrolepidoptera. This arrangement was not used in the 1962 report.
Eggs of most species are oval and usually deposited on their sides,
especially if the eggs are somewhat flattened (1, 8, 12, 21, 29, 37, 62-9).
Rarely are they spherical or scale-like. Some species deposit their eggs
in a vertical position (62-1, 62-22) or at a 450 angle (38, 62-2). Com-
paratively few deposit eggs in masses where they overlap (38, 39, 62-2,
Most geometrid eggs possess an external transparent adhesive coating.
Many are very adhesive and cannot be removed from the substrate to

which they are attached without breaking the chorion (21, 31, 38, 43, 62-9),
especially if the substrate is rough and dry. The strength of the ad-
hesive coating varies considerably. Many eggs, if deposited on a very
smooth surface like polyethylene, can be removed without breaking the
chorion, yet some of these eggs if deposited on paper toweling or bark
are firmly attached and will break if one tries to disturb their position.

A number of species have eggs that are completely or nearly non-
adhesive (3, 4, 6, 7, 45, 62-21).
The external texture of the chorion of geometrid eggs varies greatly.
Some possess a smooth shiny surface with no signs of tiny depressions or
reticulations (10, 12, 19, 20, 40, 62-33, 62-36). Other species are smooth
and shiny yet under considerable magnification, 25 X plus, show tiny
and very faint reticulations (15, 16, 41, 42, 44, 62-27, 62-32). Some of
these may be within the eggs and visible through the transparent or
translucent chorion. Many eggs of the Geometridae show on their ex-
terior distinct and prominent depressions surrounded by hexagonal or
irregular ridges producing a reticulated or net-like appearance. (18, 25,
29, 33, 34, 35, 62-5, 62-6, 62-11 to 17). Frequently these depressions are
distributed in longitudinal rows. A few of these species may possess
tiny, light colored, puff-like projections on the margins of the reticula-
tions (23, 29).
Among species in several genera and most species in a given genus
prominent longitudinal ridges occur between the two ends of the oval or
nearly spherical eggs. Cross striae or lines are present between the

ridges (3, 4, 6, 7, 45, 62-21, 62-22). Other eggs have a chalk-like, smooth
surface (13) or a granulated texture (12). A few eggs possess an
obtuse end (7, 23, 33, 34, 35, 38, 39, 43, 62-1, 62-2, 62-22) which may be
the top (62-1, 62-2) or the bottom (62-22). Eggs of a few geometrids
have a circular cap like top which comes off or is chewed off when the
larva hatches (39, 45-48, 62-1, 62-2).

Among the species seen and studied to date some interesting and
significant structural similarities exist. The eggs of most species among
the Xystrota (3), Scopula (4), Euphenolia (6), and Sterrha (7, 62-21)
resemble each other closely, all possessing distinct longitudinal ridges.

at one end or on a side. Among a few species there appears to be a
round cap-like top operculumm) present at one-end (39, 40, 45). Pressure
by the larva within pushes off this cap and then the larva emerges.
Hatching of Apicia confusaria Hbn. (45 to 50) has been observed several
times. During incubation the color of the egg changes from a uniform
green to a multicolored state (46). At prehatch time the near black larva
fills the entire egg (47). The larva pushes itself out of the round
opening (48). If the head comes out first the larva discards the empty
translucent egg shell quickly. If the anal end emerges first the larva has
a more difficult time to rid itself of the empty egg shell (49). Immediately
after emergence the larva increases in size shown in figure 50.

The immature stages of Trupanea actinobola (Loew), a seed-feeding
tephritid, infest the unopened and fully developed flower heads of the
daisy fleabane, Erigeron strigosus Muhl. One hundred seventeen un-
opened flower buds and fully opened flower heads contained 140 pupae
and 134 larvae. From 2 to 12 pupae may occupy a pupal chamber in a
seed head. Dead seeds or eaten achenes form the pupal chamber around
the pupae. Two hymenopterous parasites, Heteroschema punctata (Ash-
mead) and Colotrechnus ignotus Burks, family Pteromalidae, were reared
from the immature stages of T. actinobola. The study was conducted
during April and May 1967.


Foote (1960) reported that the genus Trupanea is a group of small
flies with grey pollinose bodies. These flies are characterized by wings
with a starlike pattern. Foote stated that the males and females of this
genus visit flowers of the family Compositae. The genus Trupanea
is worldwide in distribution, but has been neglected taxonomically since
it largely contains non-economic fruitflies. Foote stated that larvae are
known, from published literature, to feed within the ovaries of the com-
posite flowers.
The present report is concerned with the life history of Trupanea
actinobola (Loew) and is the result of a 2 month study during April
and May 1967, on Dodge Island, Dade County, Miami, Florida. An isolated
plant community of Erigeron strigosus Muhl. var beyrichii (Fischer and
Meyer) T. and G., a daisy fleabane, comprised the situation under which the
studies were conducted.
Our present knowledge of the biology of T. actinobola is fragmentary.
The larvae of actinobola were known to infest flowers of various com-
posites, but were not known to infest flower buds nor the tender stems
of the Compositae flowers (Benjamin 1934). Phillips (1946) stated that
larvae of actinobola live within the Compositae flowers and that a single
larva usually infests 1 flower head. Phillips suggested that pupae of
actinobola are formed within the flower heads, and he recorded Erigeron
sondbergiana (author unknown) as a host plant of T. actinobola in New
Benjamin (1934) recorded the host plants of actinobola as Aster
adnatus Nutt., A. carolinianus Walt., Actinospermum angustifolium
(Pursh), Coreopsis sp., and Hieracium sp. Benjamin said that 1 to 3 actino-
bola adults were known to have been reared from the above plants. He also

reported Erigeron vernus (L.) Torrey and Gray, E. quercifolius Lamarck
and Solidago sp. to be host plants of T. actinobola; however, he made no
mention of the individual flower head infestations of these plants. Foote
(1960) listed Solidago chapmanii Torrey and Gray and Solidago serotina
Retzinger as additional host plants of actinobola. According to Mr. John
Breckner (University of Florida Herbarium) S. chapmanii is a synonym
of Solidago gigantea Aiton, variety leithylla Fernald (personal corres-
pondence from Dr. Howard V. Weems, Jr.).
Foote and Blanc (1963) discussed collections of actinobola from
flowers in California and stated that actinobola represents an extremely
variable complex of North American forms needing additional study. Foote
(1960) reported that possibly a statistical study based on a much larger
number of specimens than are now available would show the presence of
several subspecies on the North American continent.


Numerous unopened flower buds and fully mature or fully bloomed
flower heads of Erigeron strigosus were collected at random in the field
and brought into the laboratory for study. A dissection needle was
used to remove larval or pupal infestations from the buds and fully
bloomed flower heads. A dissection scope was used as a visual aid in
counting the number of immature infestations and in locating the poten-
tial infestations of the buds and heads. The larval and pupal infesta-
tions were removed from the plants and placed into containers in order
to rear actinobola adults and their parasites. The container was securely
covered with a fine mesh cloth.


The female fly commonly oviposits from 1 to 12 eggs. The eggs are
laid near the center of the capitulum. The female seems to prefer the
unopened flower buds rather than the fully opened flower heads for
oviposition sites. The newly hatched larvae bore down through the
immature flowers until the seed layer has been reached. Larvae then bore
laterally through several developing seeds. As the larvae increase in
size, they feed upon more and more seeds, destroying several immature
or mature achenes. One larva devoured 32 achenes, and I estimate this to
be about 10% of the seeds within one mature flower head. Prior to pupa-
tion, a larva usually reverses its position in the seed head so that the
anterior end of the larva is oriented away from the receptacle of the flower.
The adults emerge through the dead flowers. When pupation occurs
within the unopened flower buds, the pupae may be found lying in any
position and the dead achenes or dead immature seeds do not envelop
the pupae, which lie naked and scattered within the immature disk flower
of the bud.
Fully bloomed flower heads frequently contained pupae of actinobola;
several to many pupae, usually in an upright or vertical position within
the fully bloomed flower heads, were not uncommon. Each pupa was
surrounded by and stuck to an envelope of dead achenes. The pupal
chamber or pupal cell consisted of a base of devoured achenes and an

Vol. 51, No. 2

outer margin of floral tubes around the upper surface of the group of
pupae. The number of pupae may vary from 2 to 12 adjacent to each
other and usually enveloped within a common pupal cell by the fibers of
the dead achents. The pupae were found sometimes in a horizontal
position; however, this position was not common. The dead seed cover-
ing around the pupae may afford protection from parasites for the in-
active pupae.
The flower heads of E. strigosus together with the ray flowers mea-
sured one-half inch in diameter. The flower head minus the ray flowers
measured about one-fourth inch in diameter. Indications of first and
second instar larval infestations are a greenish coloration or discoloration
on the otherwise normal disk florets of Erigeron. Fully developed larval
and pupal infestations on fully bloomed flower heads were characterized
by dead patches of disk florets. Infestations in buds prior to opening
can be detected by distorted, somewhat swollen flower buds.
Pupal infestations of T. actinobola in unopened flower buds are par-
ticularly interesting since pupal infestations of other known tephritid
flies are rather infrequent within the unopened flower buds of composites.
The unopened flower bud does not have mature achenes on which the usual
seed feeding tephritids feed, and larvae of T. actinobola are restricted to
the non-mature achenes and possibly other portions of the immature ray
and disk florets within the immature capitula. There may be several
generations of actinobola on E. strigosus in south Florida with damage
to the seeds of strigosus being extensive.

Thirty-two unopened flower buds were dissected and were found to be
infested with 70 larvae and 24 pupae. Table 1 indicates 12 unopened
flower buds were infested with 1 larva in each flower bud. The highest
number of larvae frequenting an unopened flower bud was 9. Six flower
buds contained 1 pupa in each unopened flower bud. The highest number
of pupae found infesting a single unopened flower bud was 4. In some
cases both pupae and larvae were found in a common unopened flower

Eighty-five fully bloomed flower heads were dissected and were found
to be infested with 64 larvae and 116 pupae. Twenty-one larvae and 4
pupae were parasitized. Sixteen flower heads were infested with 1 larva
per fully bloomed flower head. Twelve pupae infesting a single flower
head was the largest number found during the limited field survey.
Twenty-one fully bloomed flower heads each contained 1 pupa per flower
head. Less frequently, larvae and pupae were found infesting the same
fully bloomed flower head.

Heteroschema punctata (ASHM.):
Two females of a hymenopterous parasite, Heteroschema puncttat
(Ashmead), family Pteromalidae, were reared from the immature stages
of Trupanea actinobola in seed heads collected 6 June 1966, at Hialeah,
Florida. One specimen, USNM No. 67-386, was retained for the United

Enallnama rua n. sp., from the highlands of southern Mexico, Guate-
mala, and Honduras, is most closely related to the more northerly Enal-
lagma praevarum (Hagen), from which it differs principally by the shape
of the male appendages. The two species do not appear to intergrade
in southern Mexico.

The species of Enallagma herein described has a wide distribution in
the mountainous region between southern Mexico (Chiapas) and Honduras.
It is very closely related to E. praevarum (Hagen), which ranges from
the southwestern states of the United States south to Oaxaca, Mexico.
The lowland region of Tehuantepec may effectively separate the two
species, though there might be an effective ecological barrier should they
be found to occur in the same region: E. praevarum prefers high, rather
dry regions and the new species is found in more moist habitats.

tinctly broader than high; that is, the M1 side is broader than the Rs3 side.
Wings stalked distinctly proximal to Ac.
Abdomen: Blue, except for black markings on apical half of 1; distal
third of 2, fifth of 3, half of 4, two-thirds of 5, four-fifths of 6, seven-
eights of 7; and dorsum of 10. Black of distal fifth of 3 6 extending
ventrally to lateral mid-line of segments. Superior appendage dark, elon-
gate, equal in length to the 10 segment at mid-height, slightly curved
mesally, with broad ventral projection bearing a small, raised, subterminal
pad. Inferior appendage pale with dark tip, pointed, extending two-
thirds the length of the superior.
Genitalia: Penis very similar to that of E. praevarum (as figured by
Donnelly 1963).
ALLOTYPE FEMALE: Pale color obscure brownish-green (brown in dried
specimens). Generally similar to male, except that the proximal black
color on the femora is more restricted. The dorsum of the abdomen is
black, with pale color limited to distal half of 1, proximal eighth of 4 and
5, seventh of 6, and sixth of 7. The dark color tapers on each segment
to a rounded point proximally and expands abruptly at distal fifth of 3 7.
Segments 8 10 black dorsally, with dark color narrowed very slightly
distally on 9 and 10.
Mesostigmal laminae very similar to those of male, with anterior
margin bilobed and centrally excavated, and tip curving abruptly pos-
holotype male 24 mm; allotype female, 23 mm. Hind wing of holotype
male 17.5 mm; allotype female, 18.5 mm. Abdomens of paratypes vary
from 22.5 to 25.5 mm (32 males), and from 22.5 to 25.5 mm (3 females).
Hind wings vary from 15.5 to 18 mm (32 males), and from 16.5 to 19.5
mm (3 females). There is some variation in the relative extent of dark
and pale colors: many specimens have the central spot between the pale
postocular spots reduced, and a few have this spot enlarged to connect
the postocular spots across the center of the head. Ten males have more
dark color on the abdomen, with the distal three-fifths of 4 and four-fifths
of 5 black. The four female specimens vary greatly in size but show little
color variation. One female has the dark color at the base of the 8th
segment narrowed abruptly to a rounded point.

of Arthropods. Paratypes will be deposited in the Museum of Zoology,
University of Michigan; the United States National Museum, and several
other collections.
A total of 79 S& and 9 9 9 of E. praevarum from central and southern
Mexico, as well as many from the United States, were examined. These
specimens were all borrowed from the Williamson collection at the Uni-
versity of Michigan, and are distributed approximately as follows: Speci-
mens from Oaxaca, Michoac6n, Quer6taro, Distrito Federal, and San Luis
Potosi, all collected between 1890 and 1903, principally by Deam and by
Adams; specimens from Guerrero and Guanajuato collected in 1932 by
Smith and Taylor; and specimens from Jalisco collected in 1923 by J. H.
The new species bears approximately the same relationship to E.
praevarum in the southern part of its range as does E. anna Williamson
in the north. E. praevarum is a remarkably stable species throughout a
wide range and occurs with a large variety of other Odonata species at
most of the places it is found. Both anna and rua live in marginal areas
which must be considered harsher, judged by the relatively more re-
stricted faunas with which they coexist. E. rua was found in one locality
(Santa Cruz de Verapaz) flying virtually alone, with only one speci-
men of another species (Anomalagrion hastatum (Say) ). Seen at Caldera
Lake, it was found along with Libellula foliata (Kirby), Aeshna jalapensis
Williamson, Sympetrum illotum (Hagen), and Argia fissa Selys. At Los
Aposentos it flew with A. jalapensis, Coryphaeschna luteipennis (Bur-
meister), S. illotum and Enallagma civil (Hager). At none of the three
Guatemala localities was the Odonata fauna especially rich, nor were
specimens abundant. No information is available on the Honduras and
southern Mexico occurrences.
All of the localities at which E. rua were found were at fairly high
elevations. At the Honduras locality the elevation is given as 5800 feet;
at Santa Druz de Verapaz it is about 4900 feet; at Caldera Lake, 5900
feet; at Los Aposentos, 6500 feet; at Jitotol, 5800 feet; and at San
Cristobal de las Casas, 7400 feet.
Morphologically rua and anna differ from praevarum in about the
same way. Both species have distinctly longer superior appendages then
does praevarum, though anna is a relatively stout species, with heavy
appendages, and rua is more delicate. E. rua is distinguished from prae-
varum by its longer superior appendages, with the mesal-ventral projec-
tion far less prominent in lateral view than is that of praevarum.
The lateral aspect of the appendage of praevarum is that of a blunt
appendage, as high as long, and distinctly shorter than the tenth seg-
ment. The appendage of rua is thinner and distinctly longer than high in
lateral view. The females are not easily distinguished. The mesostigmal
laminae of rua have the mesal lobe of the anterior margin more promi-
nent than that of praevarum, and the tip of the laminae less tapered
and more abruptly rounded.
Though the species rua and praevarum are obviously close, both
appeared to be internally consistent, and there was no tendency towards
gradation between the two species. The northern species anna is closer

to rua in appearance, though it is stockier than that species and is
separated from rua by the much heavier superior appendage of the male
by the different form of the mesostigmal laminae, by its yellow costa, and
by the fact that the range of the two species are separated by about
2000 miles. Very possibly both anna and rua are only slightly derived
from an ancestral form which praevarum effectively displaced in the
major part of the range of that hypothetical species.


I am grateful to Dr. Irving J. Cantrall, University of Michigan, Dr.

species is named for Miss Ruth Birkhoff who, with her cousin Garrett
Paine, was a delightful companion on some short trips in Guatemala.

Field tests were conducted with 19 insecticides against the larvae of
the house fly, Musca domestic L. Seven were effective for 1 day, 4 for
5 days, and 3 for 7 days. All the compounds were ineffective the 9th day.
Laboratory tests with diazinon made to determine the resistance of larvae
from the field strain compared with a susceptible laboratory strain showed
that at the LCso level the field strain was 75.6 times harder to kill than
the susceptible strain and 120.5 times harder at the LCo level.

The house fly, Musca domestic L., has been and continues to be a
major problem in establishments handling caged poultry since the accumu-
lation of manure under laying hens is an ideal rearing medium for the
larvae. Even with the most effective insecticides, control of larvae in
such circumstances has been difficult. The large quantity of breeding
medium cannot be thoroughly treated because application to the surface of
the manure and constant movement of the larvae through the surface
layer mixes the chemical with the medium and quickly makes the con-
centration too low to be effective. Second, the daily deposit of fresh
manure by the chickens provides the flies with a constant supply of new,
untreated medium. Finally, and a factor that needs more study, the
chemical properties of the medium cause detoxification of the insecticides.
After the house fly developed resistance to chlorinated hydrocarbons,
organophosphate insecticides were used for larval control. Most of these
organophosphorous materials are more effective than the chlorinated hy-
drocarbons in controlling larvae at the time of application, but they
lose their effectiveness much more rapidly. Also, house flies are develop-
ing resistance to these new insecticides as they become available (La-
Brecque and Wilson 1957). Consequently, the Gainesville, Florida labora-
tory of the Entomology Research Division is making a continuous search
for new and more effective chemicals, and over the past 12 years, more
than 50 chemicals have been evaluated as house fly larvicides (Wilson and
Gahan 1957, Wilson and LaBrecque 1958, 1960, Morgan et al. 1966, and
Brady and LaBrecque 1966). Because diazinon produced complete larval
control for 1-2 weeks in 1957, it has since been frequently selected as
the standard (Wilson and Gahan 1957). However, its extensive use by
poultrymen to control house fly larvae has apparently caused the house fly
to develop resistance; Morgan et al. in 1966 could obtain only 1 day
control. In this paper, we present the results of evaluations of additional
insecticides as larvicides and describe tests of resistance of house fly
larvae to diazinon.
Nineteen compounds applied as emulsions or as suspensions of wet-
table powders were evaluated against natural infestations of house fly

Each compound was applied to the surface of 10 m2 plots of droppings
at the rate of 2 g active ingredient/m2. One liter of water was used as
the diluent for the insecticide for each plot treated. A small carbon
dioxide cylinder charged to a pressure of 70,000 g/cm2 (about 1,000 psi)
was adapted to a two-liter compressed air sprayer. This cylinder was
equipped with a pressure regulator that maintained a constant pressure


Bailey: House Fly Control with Larvicides


of 3,000 g/cm2 (about 40 psi) in the spray tank. All hoses had quick-
disconnect couplings to make loading the tank easier. The sprayer was
equipped with a TeeJet 80-02 nozzle that delivered 1 liter of spray per
minute. This type sprayer had not previously been used to apply larvi-
cides, but it proved superior to hand pump sprayers and enabled us to
treat a large number of plots in a relatively short period by eliminating
the time required for pumping.
Larval density in each plot was determined by collecting a large
spoonful of manure from each of 10 locations where the heaviest infes-
tations were apparent, spreading the samples on a plywood panel, and
counting the larvae present. The effectiveness of the treatments was
determined by comparing the difference in counts made immediately
before and 1, 5, 7, and 9 days after treatment. The compounds were
considered ineffective after control dropped below 75%.
Also, a sample of adult flies was collected at the poultry farm, brought
into the laboratory, and reared to the F, generation. The resistance of
the F1 larvae to diazinon was then determined by comparing their
susceptibility to diazinon with that of the Orlando regular (susceptible)
strain as follows: technical diazinon in 50 ml water was thoroughly
mixed (in 225 g cups) with 25 g dry CSMA larval medium at concen-
trations of 3.0, 1.0, 0.3, 0.1, 0.03, 0.01, 0.003, or 0.001 mg toxicant/g med-
ium. Then 50 third-instar larvae were placed on the medium in each cup,
and a piece of organdy cloth was laid over the top and secured by a
rubber band. Each concentration and an untreated check was replicated
once for each strain of flies. The cups were held at 27 C and 50% relative
humidity until the larvae pupated and emerged as adults. Percentage
mortality was computed from the number of larvae that failed to develop
into adult flies, and the data were used to compute the LCso's and LCgo's.


The results of the field test are presented in Table 1. Of the 19 com-
pounds tested, 7 were effective for 1 day and 4 were effective for 5 days.
At the 7th day, reduction from the wettable powder suspensions of Bay
62863 and Shell SD-8447 and an emulsion of dimethoate was still above 75%
All compounds were ineffective the 9th day. Calcium arsenate, which
was being used by personnel at the poultry farm for larval control
before the test, showed only 27.2% reduction the 1st day after treatment.
This percentage was not much higher than natural reduction in the un-
treated checks (20.3%) the 1st day, but the checks then showed no reduction
during the remainder of the test.
Diazinon, which has been used for several years to control house fly
larvae and which was effective during the early years of its use, gave
57.4% reduction after 1 day. The laboratory comparison of the resistance
of larvae from the field strain with the susceptible laboratory strain is
shown in Table 2. At the LC,5 level, the field strain was 75.6 times
harder to kill than the susceptible strain, and at the LCGo level, it was
120.5 times harder to kill. Thus investigators in various parts of the
country would be well advised to evaluate the resistance in house flies to
chemicals presently recommended for their control.

The ground cover plants in banana plantations of the Ulua Valley in
northern Honduras were examined for aphids, particularly Aphis gossypii
Glover, Rhopalosiphum maidis (Fitch), and Myzus persicae (Sulzer)
which have vectored a virus disease of bananas experimentally. In addi-
tion, the following aphids were found: Aphis nerii Boyer de Fonscolombe,
A. craccivora Koch, A. spiraecola Patch, A. coreopsidis Thomas, A. illinoisen-
sis Shimer, Toxoptera aurantii (Fonscolombe), Tetraneura hirsuta (Baker),
Capitophorus eleagni (Del Guercio), Hysteroneura setariae (Thomas),
Hyadaphis pseudobrassicae (Davis), Tinocallis kahawaluokalani (Kirk-
aldy), Dactynotus verbesinae (Boudreaux), and Pentalonia nigronervosa
(Coquerel). The host plants and the place on the plant where the aphids
were found are listed under each aphid species.

In 1955, Dr. C. W. Wardlaw found a virus disease in commercially
grown Giant Cavendish bananas in the Aguan River Valley near La Ceiba,
Honduras. By 1957 the virus, infectious chlorosis, began to appear in
Gros Michel bananas in plantations in the Ulua Valley over 100 miles
from the first discovery. The virus was transmitted between bananas
experimentally by Aphis gossypii Glover, Rhopalosiphum padi (L.), R.
maidis (Fitch), Myzus persicae (Sulzer), and Acyrthosiphom pisum (Har-
ris) (Waite 1960). In addition, the virus produces mosaic symptoms on
Physalis sp., Isotoma longiflora (L.) Presl., Ricinus communis L.,, Cucumis
sp., Cucurbita sp., Crotalaria sp., and Pueraria sp., plants found in or near
banana plantations.
In 1961, an outbreak of infectious chlorosis prompted a study to
determine all the aphid species and their host plants in banana farms.
This study was begun by Dr. E. R. Willis now at Illinois State Normal
University, Normal, Illinois. The host plants were determined by Mr. J.
D. Dickson, Division of Tropical Research, La Lima, Honduras. The
aphids were identified by Miss L. Russell, USDA Entomology Research
Division at Washington, D. C., Dr. M. E. McGillivray, Can. Dep. Agr.,
Fredericton, N. B., Dr. Clyde F. Smith, N. Carolina State College,
Raleigh, N. C., and Dr. J. O. Pepper, The Pennsylvania State University,
University Park, Pa.

The banana farms surveyed were situated along the Comayagua, Ulua,
and Chamelecon Rivers, north and south of La Lima, Cortes, Honduras.
The area is approximately 40 miles long and 5 to 10 miles wide.
The plants in 14 2-acre stations were examined for aphids every
month for one year, then at intervals when time permitted. All aphids

collected were preserved in alcohol. There was no definite system of
plant inspection. Usually a team of three surveyors worked in each
station for approximately one hour. Every plant encountered was ex-
amined. Specimens of plants hosting aphids were collected in plastic
bags and identified.
There are undoubtedly more aphid species and host plants still to be
collected in the banana plantations. In fact, five unidentified aphids were
collected in addition to those presented below. The aphids are listed in
order of approximate abundance, the most frequently found aphids listed
first. Where possible, the common and scientific names follow the approved
list of the Entomological Society of America.

Adults and nymphal stages of Pseudoparasitus thatcheri n. sp., a mite
associated with beetles occurring under bark of southern pine trees in
Louisiana are described. Generic placement of the species is discussed.

At present authors disagree on the generic limits of Pseudoparasitus.
The species described here shows characters of both Pseudoparasitus and
Hypoaspis, as defined by Evans and Till (1966). Evans and Till would
exclude it from Pseudoparasitus for the following characters: apotele
2-tined; tectum smooth; podal plate not strongly enlarged posterior to
coxa IV; para-anals not at anterior level of anal opening; and seta av1 on
femur II not spinelike in the female or spurlike in the male. Hunter
(1966) broadens Pseudoparasitus to include some species from the Nearc-
tic area which have podal plates not strongly developed, para-anals not
at the anterior level of the anal opening, and seta av, not spinelike in the
female. A study of material from other areas of the world is needed to
determine if these characters are variable in this genus. We have chosen
to place the species described below in Pseudoparasitus.

Description and measurements based on a series of 5 females, 5 males,
3 deutonymphs, and 1 protonymph. Holotype (female) data: in boring
dust from loblolly pine (Pinus taeda L.) containing Dendroctonus fronta-
lis Zimm. and wood borers; 16 June 1966: John Moser, coll.; Elizabeth,
Louisiana. Data for all slides same as for holotype. Holotype, male
and d-utonymph paratypes deposited in U. S. National Museum, Washing-
ton, D. C. Remaining specimens (paratypes) deposited with Department
of Entomology, University of Georgia, Athens.
P. thatcheri was discovered as a part of a larger study by R. C. Thatcher
(for whom the mite is named) to determine the seasonal variations in
activity of Dendroctonus frontalis Zimm. in Pinus taeda L. at Elizabeth,
Louisiana. This investigation was similar to another in east Texas
(Thatcher and Pickard, 1964).
Between 1 January 1966, and 17 April 1967, bolts were cut from trees
every 2 weeks at various heights of infestation, and the bark beetle
galleries examined for mites. When all beetles had emerged (about 30
days after the bolts were cut) galleries were again investigated, as well
as the boring dust.

Hunter: Pseudoparasitus thatcheri n. sp.

During the 16-month period, P. thatcheri was found 6 times in bolts
cut 16 May, 30 May, 14 June, 26 July, 5 September and 3 October at
heights of 16, 34, and 51 feet. Relative abundance was infrequent 4 times,
common once, and rare once. Adults were always seen, and occasionally
nymphs and larvae were collected. The mite was found only after beetles
had emerged from bolts, and usually was present in dry boring dust.
D. frontalis and cerambycid(s) infested trees on all 6 dates, but Ips
spp. on only 3 dates. Hence the former appear to be more likely carriers.
The species was always in association with 6 to 20 other species of mites.
No observations were made on its feeding habits.

PRINCIPLES OF INSECT PATHOLOGY. Edward A. Steinhaus (University of
California, Irvine, California). Reprint of 1949 edition. Hafner
Publishing Company, New York and London. 1967. 757 pp. $15.75.

It is of interest that this fine text has been reprinted in its original state
and is again available. The Hafner Publishing Company, by providing a
new source for this book, demonstrates a concern for the continued demand
for comprehensive literature in the field of insect pathology. The original
edition, printed in 1949 by another publisher, was the first book in English
to assemble and review the widely scattered literature on the subject.
The introductory chapter of the book outlines the relation of insect
pathology to other branches of entomology, briefly reviews the historical
aspects, and discusses techniques. Chapters 2 and 3 consider the effects of
mechanical, physical, and chemical injuries and abnormalities due to nu-
trition and metabolism. An 83 page discussion of the intracellular and
extracellular microbiota of healthy insects is followed by chapters dealing
with epizootiology, resistance, and immunity. Chapter 8, devoted to symp-
toms and pathologies of various types of infections, is especially useful as
a reference for those not trained in pathology who occasionally observe
diseased insects in field collections.
Chapters 9 through 13 deal with diseases caused by bacteria, fungi,
viruses, protozoa, and nematodes, respectively. As would be expected, these
chapters comprise the major portion of the book and provide excellent sum-
maries and discussions of work in these areas to the time of first publica-
tion. The final chapter covers applied insect pathology and biological con-
trol. References are given at the end of each chapter, and an 8-page
author index is included just before the complete subject index.
A more recent two-volume advanced treatise on insect pathology edited
by the same author covers the basic studies in more detail and presents new
areas of research. This tremendous proliferation of studies in insect path-
ology may explain why the book in review is still so necessary as a standard
text and reference. It will continue to be useful to entomologists, micro-
biologists, and all those who want fundamental information about this rela-
tively new science. Hopefully, the present review will serve as a recom-
mendation for its use by those unacquainted with its contents.
