Radioisotopes have been used with great success in tracing particular
elements. The need for effective markers in ecological studies has led to
the use of radioactive materials as markers of individual animals in dis-
persal studies, measurement of population densities, and behavior exam-
inations. Tagging with radioisotopes rather than conventional pigments
and dyes has definite advantages. Pigments may rub off, fade, or be elim-
inated during molting. Examination of large groups of insects for spe-
cially colored individuals can be a tedious task. Radioisotopes administered
internally either by feeding or injection provide an internal tag that will
not rub off and that permits rapid counting of large populations.
There are several disadvantages to the use of radioisotopes. Toxicity
to individuals can be a problem if a high level of radiation is present since
it will not only reduce the number of labelled insects but also cause errors
in interpretation of results. Another possible disadvantage is change in
behavior of the labelled insect contrasted with the unlabelled one.
The recent monograph by O'Brien and Wolfe (1964) includes the most
comprehensive review of work utilizing radioisotopes in entomology.
Studies on foraging intensity of honey bees by Lee (1965) utilized P3
and I1'. A dose of 1 me of P" per colony (1 mc/2 quart solution) pro-
duced a significant effect on distribution of foragers from the hive. An
effect was also shown with a 1.5 me dose of I"'. Hassett and Jenkins (1949)
reared larvae of Aedes aegypti (L.) in water containing 1 pc P"/ml and
produced adults having counts up to 10,000 per minute. Third and fourth
instars were successfully tagged, younger larvae were too sensitive, and
pupae absorbed too little phosphorus. The effects of tagging with P3"
were studied by comparing stage, age, and P32 concentrations. Since con-
centrations of P32 greater than 1 fc/ml were harmful from the standpoint
of life history, it was hypothesized that higher concentrations also affected
Although careful studies of life cycles, longevity, and reproduction have
been made, there appear to be no significant reports on behavior of tagged
mosquitoes. The purpose of this study was to determine if varying levels
of radiophosphorus (P32) had any effect on the light response of tagged
A. aegypti larvae.

Aedes aegypti larvae were chosen because they are characteristically
negatively phototaxic. Prior to each of three replications, 400 mechanically
separated third instar larvae were obtained from the laboratory colony at
the USDA Laboratory for Insects Affecting Man and Animals, Gainesville,
Florida. One hundred larvae were manually separated into a 400 ml glass
beaker for each of the four treatments. Each beaker contained 250 ml. of
distilled water.
The four treatments were HIO, 0.1 uc P"/mI, 5 uc P"/ml, and 1 ml of
0.5 N HPOa. The desired amount of P2 (P-32-P-Processed, Carrier Free,

as POI in weak HC1, a 0.5 N solution) was calculated and added to two treat-
ments. The volumes added for the 0.1 uc/ml dosage were 25, 28, and 30
u liters. Those for the 5 Mc/ml dosage were 1250, 1370 and 1540 p liters.
Prior to each of the three replications, correction was made for radio-
decay. The P32 was produced and assayed by Union Carbide which operates
the Oak Ridge National Laboratory, Oak Ridge, Tenn., under contract to
the Atomic Energy Commission. The larvae were kept in the radioactive
solution for 24 hours. At the end of this period they were transferred to
fresh water. Each group was fed about 25 mg of crushed dog food.

For observing response to light, a cylinder equipped with a trap funnel
was used (Fig. 1). The cylinder and funnel were made of cellulose acetate
and were then mounted on a 6-inch plastic freezer dish. The cylinder was
18 inches deep and the bottom of the funnel was 12 inches from the top.
The funnel plug was a truncated cone of plastic, the top of which was ringed
with a 1/2-inch strip of sponge rubber to provide a good seal. The floating
plug was manipulated with a string through the drain plug.
At the beginning of the observation the cylinder, which was lighted
from below, was filled with water and the funnel was plugged. The larvae
were poured from a beaker into the top of the cylinder. All of the treat-
ments were tested in a random sequence. After the larvae quieted, the
funnel plug was floated up and the bottom light turned out. A pause of a
few seconds was allowed and the top light was turned on for 20 seconds.
The funnel was again plugged at the end of this timing. Fig. 1 shows the
plug positions during the test. Each treatment was conducted in a dark
laboratory with the investigator well away from the apparatus. Water

and mosquitoes from the top of the apparatus were siphoned off. The drain
plug was pulled and the water and mosquitoes in the bottom of the appa-
ratus were collected. The larvae from the top and bottom were counted.
For counting of radioactivity, eight larvae were taken from the top and
bottom of each replication, placed in 2-inch aluminum planchets, and dried
under infra-red lamps. A Packard Scaler-Ratemeter, Model 150, with a
Nuclear Chicago Geiger-Mueller tube having a 1.4 mg/cm2 mica window
was used for counting. Counts were taken at one-half inch from the tube
The data for the three replications are given in Table 1. The larvae,
top and bottom, from each of the treatments, were counted for radioactive
content to determine if there was any variation in the level at which they
had absorbed the isotope. The paired t test on these data showed no sig-
nificant difference between the radioactivities of the larvae in the top in
relation to those in the bottom. Also tested was the dosage variation in
tagging levels throughout the replications. No significant difference was

This study indicates that a concentration of radiophosphorus .1 gc/ml

activity must have caused the variation in response and not the phos-
Since radioisotopes are being used so commonly as labelling tools, it is
important to understand that their use might alter behavioral patterns
and lead to unreliable information. A behavioral change in the larvae of
A. aegypti does not mean there would be a behavioral change in the adult,
but it does open the area to further study.
Tagging mosquitoes for the release-recapture method of population
sampling requires that the adults merely be radioactive enough to be de-
tected. This may allow use of concentrations of isotopes below the dele-
terious levels. Many tagging techniques require the use of very high
concentrations of radioactive material. For this reason, the reactions of
the specific insect to the chosen radioisotope should be thoroughly studied
with relation to behavior and life history prior to any organized research
I am indebted to B. G. Dunavant, Assistant Director of Nuclear Sciences,
and Gordon Renshaw, Nuclear Technician, for permitting the use of the
radiation laboratory facilities and equipment. I also express my gratitude
to William Yearian for his suggestions and valuable statistical assistance.

Wireworms became a very serious problem on potatoes in south Florida,
beginning about 1940 and they remained serious until the use of chlordane
began about 1949. Chlordane, aldrin, and heptachlor were used successfully
for about a decade on the species Melanotus communis Gyll. Now, however,
these insecticides are not as effective as in previous years. A Conoderus
sp., possibly C. falli Lane, is currently present in the shallower marl and
rockland soils, and may be spreading to the deeper soils. More complete
drainage of the area and a series of seasons with less than average rainfall
may have changed conditions to permit the Conoderus sp. to live and de-
velop in the deeper marl soils. Where Conoderus sp. is involved it is not
unexpected that a control problem exists since Reid and Cuthbert (1956)
and Norris (1957) reported the species was resistant to the chlorinated
The Perrine marl soils which are used for potato production are very
finely divided calcareous particles, and range in depth from a few inches
to several feet. They overlie oolitic limestone and range in pH from about
7.8 to 8.3. Such high alkalinity may accelerate decomposition of many
otherwise effective insecticides.

Experiments initiated in 1946-47 (Wolfenbarger, unpublished data) in-
dicated that 65 pounds of DDT per acre gave 50% reduction of wireworm
injuries. The soil fumigants D-D and EDB gave less than 60% control.
Benzene hexachloride offered promise of control but contaminated the
tubers. In 1947-48, chlordane and lindane were first tested; also, cleanly
cultivated plots, and plots planted to sesbania, velvet bean, buckwheat, and
sesbania mixed with velvet beans as cover crops gave measures of control.
Chlordane and aldrin (the latter first used in 1948-49), however, gave the
most effective results. Preplanting soil treatments were more effective
than post-harvest (spring) applications. It was found that although fer-
tilizer-insecticide combinations were effective, broadcast methods were more
effective. These recommendations were practiced by growers who reported
few or no wireworm injuries until 1961. In 1962, 1963, and 1964, wireworm
injuries again reduced the grade of some lots of potatoes.
Some differences are recognized in control of wireworms affecting corn
and potatoes. Wireworms begin feeding on sprouted corn, and within a
few days to a month after planting have killed or damaged the plants.
Although wireworms damage sprouting potatoes and feed on the seed-
pieces, the most damaging part of the feeding is on the new potatoes. Such
feeding is done on developing tubers and extends until harvest. Control

Wolfenbarger: Control Experiments on Potatoes

of wireworms on corn must occur before or immediately after the seed is
planted. Control of wireworms affecting potatoes need not begin until a
few weeks after planting and protection must be maintained until harvest.
Corn is not planted as deeply as potatoes and may be protected by shallow
application as contrasted with potatoes.


Tests were made usually in commercial plantings in cooperation with
growers. Plots ranged in size from single rows 100 feet long to four rows
each 25 feet long. There were four replications of each treatment. In the
broadcast method, insecticides were scattered by hand over the plots, then
worked in the top 21/2 inches of soil with disk or tiller. Granulated ma-
terials applied in the row were placed in a furrow about 21/2 inches wide
and 2 inches deep, and covered. By the drench method, emulsion or wet-
table powder formulations were applied in 1 foot wide bands with a sprin-
kling can with water at the rate of 500 gallons per acre. Seed was planted
the next day or soon thereafter in the above methods. Phorate was omitted
from the Experiment Station tests because it was used by the grower all
around the test plots. The grower applied granulated phorate with the
seed pieces at planting time. Planting was done in November or early
December by the grower. Cultivating and spraying were done according
to grower practices and were the same over all plots. Sample tubers, 100
or more from each plot, were harvested by hand digging in February or
March, and washed for examination. Corn plants were counted periodically
to a month after planting, although the data presented in Table 2 were
taken a month after planting.
Proprietary materials used in the tests are as follows:

3-yl-methyl] dithiophosphate

In the 1962-63 season, broadcast and in-the-row applications gave results
indicating no or indefinite control. Broadcast and disked-in applications of
the following amounts per acre gave results which were little different from
the checks: diazinon, 10G, 40 lb.; phorate, 10G, 30 lb.; heptachlor, 4E, 1
gal.; Di-Syston 10G, 30 Ib.; Kepone, 5% on corn meal, 50 lb.; parathion,
10G, 20 lb.; aldrin, 4E, 1 gal.; Isolan 2/2G, 160 lb.; and Telodrin 5G, 120 Ib.
Chlordane formulations of 40W, 40G, and 8E applied to give 6 Ib. tech-
nical material per acre gave mean values of control that were essentially
equal, and were significantly less than the check mean.

The Florida Entomologist

Fewer broadcast treatments and more in-the-row treatments were made
in the 1963-64 season. Results of wireworm tests on potatoes are given
in Table 1.
Thirty pounds of 10G phorate per acre, applied in the furrow with the
seed pieces, gave the most satisfactory control. Aldrin, chlordane, and
heptachlor, previously satisfactory in control, were comparatively ineffec-
tive, and are unsatisfactory in grower practices.
Parathion never controlled wireworms in the experiments, possibly be-
cause it was decomposed by the highly alkaline soils.
Results of wireworm control on corn are given in Table 2. More corn
plants grew in soil treated with phorate and Kepone than with any other
treatment, although there were no significant differences between treat-
ments. Chemically treated plots had more plants than the untreated ones.


The chlorinated hydrocarbons aldrin, chlordane, dieldrin, and heptachlor
are ineffective, so other insecticides are needed for control of wireworms.
Phorate, an approved material at 3 pounds technical material per acre on
potatoes and 1 pound on corn (although more material would give better
control), is currently recommended for wireworm control. In order to be
effective, however, it must be placed in the furrows with the seed or seed

Two of the phytoseiids described in this paper belong to the genus
Cydnodromus Muma, 1961. This genus has 6 pairs of dorsal setae, 3 pairs
of median setae, 8 pairs of lateral setae, most of them short and simple,
2 pairs of sublaterals setae on the interscutal membrane, 3 pairs of sternal
setae and 3 pairs of preanal setae. Leg IV may have 1 or no macrosetae
(Muma 1961). Most of the species that belong to this genus are found
in litter or on low growing plants but are found occasionally on plants sev-
eral feet above ground level. Living mites are off-white to very light tan
and small in size. Most phytoseiids are thought to be predaceous, but the
food habits of these 2 species are unknown.
Two of the species belong to the genus Amblyseius Berlese, 1914. This
genus has 6 pairs of dorsal setae, 3 pairs of median setae, 8 pairs of lateral
setae, some elongate and weakly plumose, 2 pairs of sublaterals setae on
the interscutal membrane, 3 pairs of sternal setae, and 2 or 3 pairs of pre-
anal setae. Leg IV has 3 macrosetae (Muma 1961). The species in this
genus may be found in litter, on low growing plants, and on plants several
feet above ground level. The food of these species is unknown, but they are
probably predaceous on small arthropods. The live mite is medium size
and off-white in color.
The modified Garman system of setal designation, except in the case of
the median setae, is used in this paper. If a pair of setae on the middle
third of the dorsal scutum, L5 of authors, lies distinctly mesad to a pair
of marginal lateral setae, it is considered median; if only 1 pair of setae
is present or it is not distinctly mesad, it is considered lateral. The above
characters refer to females; data on males are incomplete for many species.
All drawings and measurements were made with a phase contrast com-
pound microscope at 1200 magnifications for leg IV and 800 magnifications
for all other illustrations.

The devastating damage to citrus trees caused by extremely low tem-
peratures in December 1962 resulted in a near failure of the 1963 citrus
honey crop (Robinson 1963). It has been generally believed that citrus
nectar flows are adversely affected for two years following severe freeze
damage to the trees, and many Florida beekeepers were quite pessimistic
about the chances of making a good citrus honey crop in 1964. There was
some evidence to support this belief, since the 1958 and 1959 citrus honey
crops were rather poor after the trees in many areas had been damaged by
freezes during the winter of 1957-58. The pessimism proved to be unjusti-
fied, and 1964 turned out to be a banner year for citrus honey production.
The average production of citrus honey for the last five years by colonies
in the Experiment Station apiary located near Clermont, Fla., is shown in
Fig. 1. In 1964 the 35 colonies in the apiary had an average production
of 128.4 lb. per colony. This figure is almost 50% greater than the previous
highest yield of 86 lb., record in 1961. Although the blooming period of
the groves in the Clermont area lasted a total of 39 days, over 90% of the
honey was produced during the last half of this period. Flowers opened
very slowly during the first two weeks of bloom when fairly low tempera-
tures were experienced. Later, when the weather moderated, the flowers
opened very quickly, and the nectar flow was unusually heavy. This period
of heavy nectar flow lasted for 21 days, during which time the colonies
made gains averaging 111.4 lb. In one 48 hour period between 8:00 AM,
18 March, and 8:00 AM, 20 March, one group of colonies had an average
gain of 42 lb. Most of the other colonies in the apiary made gains of 30
to 35 lb., and the least productive colony in the apiary gained over 23 Ib.
The 1964 citrus nectar flow was not only exceptional in regard to the
amount of nectar secreted, but the quality of the honey produced from the
nectar, as measured by its color and moisture content, was the best of any
citrus honey produced in the last twelve years (Table 1).
The data regarding the moisture content of citrus honey for the period
of 1953-1962 was obtained from information published by Haynie (1962).
The Pfund scale values were derived by converting the data published by
Haynie (1962) as to the percent light transmission of citrus honey produced
in the same years. Data for the year 1964 were collected by the author.
This information shows that only in 1961 was the color of citrus honey
nearly as light as that produced in 1964. However, the 1964 honey had
almost 3% less moisture than the 1961 honey. Florida honeys are seldom
light enough to be graded water white (Pfund value of 7 or less), yet 9
of 17 samples tested from the 1964 crop were in this grade. One honey
sample produced by the colonies near Clermont showed a Pfund reading
below zero, which is about as clear as any honey can be.

The cowpea curculio, Chalcodermus aeneus (Boh.), boll weevil, Anthono-
mus grandis (Boh.), and corn earworm, Heliothis zea (Boddie), are major
pests in the Lower Rio Grande Valley. These insects are controlled by
frequent applications of highly toxic insecticides. Because it is suspected
that a tolerance may exist or develop in the near future, experiments were
conducted during the 1963-64 season to determine (1) whether insecticide-
oil combinations were more effective against these pests than insecticides
alone; (2) whether the methods of applying these insecticides and insecti-
side-oil combinations would affect control of these insects and; (3) whether
other insecticides would control these insects.
Dogger (1955) showed that isoparaffinic oils do not increase effective-
ness of toxaphene + DDT for bollworm and boll weevil control on cotton.
Wolfenbarger and Schuster (1963) and Wolfenbarger (1964) found Bidrin,
Bayer 25141, and Guthion to be effective against the cowpea curculio.

Six experiments were conducted during 1963-64. Plots in all experi-
ments were 1 row wide (38 inches between rows) and 30 to 50 feet in
length arranged in randomized block design with four replications. An
oil-water-insecticide combination and an aerosol were used to apply the in-
secticides in various experiments. The oil-water-insecticide combinations
were applied at 40 to 80 gallons per acre with a carbon dioxide powered
sprayer at 40 psi using three nozzles per row. The aerosols (very fine
mist) were applied with a Soloport pack back gasoline powered airblast
spray at 1/ to 2 gallons per acre through two adjustable nozzles per row.
Two emulsifier systems, designated as unstable and stable emulsion sys-
tems, were used with the oil-water-insecticide combinations applied with
the CO2 powered sprayer. The unstable emulsion system had a 1% con-
centration of B-1956 (modified phthalic glycerol alkyd resin). The stable
emulsion system used an amine soap, and was stable during the entire
period of the spray application.
Experiments were conducted for control of the cotton boll weevil and
cotton bollworm on cotton. In 1963, the plots were established to evaluate
toxaphene + DDT, Guthion + DDT, and methyl parathion + DDT alone
and in combination with various oil fractions (Tables 2, 3, 4). The oil frac-
tions were naphthenic, paraffinic, and isoparaffinic in structure. The amine
soap emulsifier system was used in these evaluations. The specifications
of the oils are summarized in Table 1. The oils were applied at the rates
at 1.5, 3.0, and 4.5 gallons per acre.

In 1964, plots were established to evaluate oils representing a naph-
thenic, paraffinic, and isoparaffinic oil fraction at 3.0 gallons per acre in
combination with toxaphene + DDT at 3.0 + 1.5 lbs. active ingredient per
acre (Table 5). The insecticide-oil combinations were compared to toxa-
phene + DDT insecticide combinations of 3.0 + 1.5 and 6.0 + 3.0 lbs. per
acre. The data for both rates are summarized because no differences ex-
isted between the rates or control of either insect. These treatments were
compared to an untreated check and toxaphene + DDT alone in four tests.
In three tests, insecticide-oil-water sprays were applied at 56 gallons per
acre. All treatments were applied with the CO2 powered sprayer. The
fourth test was designed to evaluate an aerosol application at % gallon
per acre. Treatments were evaluated by examining 50 squares or bolls per
plot for boll weevil feeding or oviposition scars and bollworm larval feed-
ing damage. Open boll counts on 50 plants per plot were made once as a
relative index of yield.

Sweet corn plots were established in the fall of 1963 and the spring of
1964 for corn earworm control. In the fall 1963, four insecticides and two
emulsifier systems for each of 3 oil fraction-DDT combinations, at equal
rates, were used. The three fractions represented paraffinic, naphthenic,
and isoparaffinic type oils. The 1964 experiments were established to use
insecticides, aerosol application of oil-DDT combinations, and oil-water-
insecticide combinations. Two oil-water-insecticide emulsifier systems were
used as in the fall 1963 experiment. The treatments (Tables 6, 7) were
evaluated as described by Wolfenbarger (1964).

In 1963-1964, insecticides and insecticide-oil combinations were used for
cowpea curculio control on southernpeas. Two emulsifier systems of the
water-oil-toxaphene combinations were evaluated and compared with toxa-
phene alone in both tests. During the spring of 1964, aerosol applications
of toxaphene-oil were made at the rate of 1.5 gallons per acre. Guthion
and methyl parathion were applied at 4 different rates and 1 to 4 times. In
both experiments, applications were initiated at first blossom. The treat-
ments were evaluated as described in Wolfenbarger & Schuster (1963) and
Wolfenbarger (1964), and the data (Tables 8, 9) are presented as larvae

The results in all experiments are expressed as per cent increase in
control over the untreated check or as indicated in the summaries in Tables
3, 4, 7, and 9. The data in Table 2 show that the 1.5 and 3.0 gallons per
acre rates of paraffinic oil-DDT- + Toxaphene combination gave control
of the boll weevil and corn earworm which was superior to the use of
DDT + toxaphene alone. This insecticide-oil combination gave better con-
trol than all other treatments and the check. The rate of oil (Table 4) in the
insecticide-oil combination did not increase insect control. The data (Table
5) show that all aerosol applied insecticide and insecticide-oil combination
applications increased corn earworm and boll weevil control over the oil-
insecticide-water applied combinations. The oil-water-insecticide combina-
tions or insecticide combinations were ineffective in controlling the boll
Data in Table 6 show that Monsanto 40273 and Monsanto 40294 gave
the best corn earworm control on sweet corn and were equal to or superior
to DDT at the 1 lb. per acre rate. Monsanto 40273 was superior to DDT
at the 2 lb. rate but equal in effectiveness at the 4 lb. rate. DDT was
equal or superior to Monsanto 40294 at 2 and 4 lbs. per acre. DDT-oil-com-
binations were not as effective as DDT alone at equal rates, when applied
as an aerosol spray at the rate of 1 and 2 gallons per acre. The stable
emulsion system was generally superior to the unstable emulsion system
(Table 7). The water applications of the oil-insecticide combinations were
superior to the aerosol applications of oil-insecticide sprays. The oil frac-
tion possessing a predominance of paraffinic type molecules gave the best
corn earworm control compared to the naphthenic or isoparaffinic type oils
(Wolfenbarger 1964). Naled and the naled-oil combinations were ineffec-
tive for corn earworm control.
The data in Table 8 show that parathion, methyl parathion, Monsanto
40273, Giegy 13005, Guthion, SD9129, and Bidrin were the most effective
insecticides for cowpea curculio control. Phosphamidon at the highest rate
offered promise for curculio control. Three and 4 applications of Guthion

were superior to 1 and 2 applications for cowpea curculio control. Three
and 4 applications of methyl parathion at each of 3 rates were superior
to 1 or 2 applications. There were no differences between 4 applications
of methyl parathion at 0.5, 1.0, or 1.5 pounds per acre, Toxaphene and
naled were ineffective for cowpea curculio control. The use of stable and
unstable emulsion systems, aerosol applications, and oil had small effects on
control (Table 9).

The following notes include a new synonymy for Ectopsocus pumilis
(Banks), synonymic notes on Ectopsocopsis cryptomeriae (Enderlein), rec-
ords of three species of Ectopsocinae previously not known to occur in the
Western Hemisphere, and distributional records of two others. Two of
the species, Ectopsocus maindroni Badonnel and Ectopsocopsis cryptomeriae
(Enderlein) are recorded for the first time from the United States, thus
raising the number of species of Ectopsocinae known to occur in the United
States to seven. Three of these were recorded by Mockford (1959), and
references to the other four are included herein. Of general interest is a
corrected identification of the form which has been called Ectopsocus pumilis
(Banks). This species, exceedingly common in eastern United States, has
now been shown to be Ectopsocopsis cryptomeriae (Enderlein). The name
pumilis applies to another species.

Ectopsocus maindroni BAdonnel (1935: 81)
A bibliography on this species is given by Thornton (1962: 299). The
species has not previously been recorded in the Western Hemisphere. On
several occasions it has been found by U. S. Department of Agriculture
plant quarantine inspectors on materials entering the United States from
Mexico, South America, and the West Indies.

Ectopsocus ornatus Thornton (1962: 308)
This species has been recorded previously only from Hong Kong. A
single female was taken by U. S. Department of Agriculture officials in
San Juan, Puerto Rico, on vegetables originating at an unspecified locality
in Puerto Rico.
The following measurements and ratios were recorded for this speci-
men: IO/D (Pearman method), 3.36; IO/D (Badonnel method), 2.34; body
length, 1.62 mm; forewing length, 1.55 mm; distal hind tarsal segment,
0.091 mm; ratio proximal/distal hind tarsal segments, 2.32; antennal length,
1.14 mm; basal flagellar segment, 0.258 mm; hindwing length, 1.20 mm;
hind femoral length, 0.38 mm; hind tibial length, 0.58 mm; proximal hind
tarsal segment, 0.212 mm; second flagellar segment, 0.152 mm; ratio
basal/second flagellar segments 1.70.
All of the above measurements fall within the range for the species
given by Thornton, or are so close to the limits of the range that their
degree of accuracy (to 0.015 mm) cannot clearly delimit them from it.
The IO/D figure of 4 stated by Thornton (presumably using the method


Mockford: Notes on Some Species of Ectopsocinae 113

of Pearman described by Ball 1943) seems decidedly larger than that stated
above, but there is no information by which to determine whether my
figure falls within or without the range for the Hong Kong material.
The genitalia differ from those figured by Thornton in that the third
valvulae (outer lobes of the gonapophyses of the ninth segment) bear, in
addition to the three long outer hairs, only seven shorter hairs, rather
than ten.
Wing markings differ from those illustrated by Thornton in that the
pterostigma has a clear border in its apical third, and the medial stem just
distal to its junction with Rs has a clear posterior border for a short dis-
A few hairs are visible on the radial margin of the forewing at 440X,
but at lesser magnifications these are not visible.

Ectopsocus pumilis (Banks)
Peripsocus pumilis Banks (1920: 313) (nec Ectopsocus pumilis (Banks)
Chapman, 1930).
Ectopsocus ghesquierei Ball (1943: 11), new synonymy.
An examination of the holotype, a female, in the Museum of Compara-
tive Zoology, Cambridge, Mass., has shown that this is not the species which
Chapman (1930) and all subsequent North American authors have assumed
it to be. Such an error is certainly excusable in view of the fact that there
is nothing diagnostic in Banls' description of the species, and it was very
likely impossible for Chapman to make a potash preparation of the type.
Subsequent authors, including myself, have simply followed Chapman's
A comparison of the subgenital plate (Fig. 5) of this species with that
of E. ghesquierei Ball (Ball 1943, Fig. 6) shows a virtual identity in form,
details of pigment distribution, and ciliation. The type of E. pumilis lacks
a definite submarginal row of macrochaetae paralleled by a line across the
subgenital plate, but another specimen examined (from Gainesville, Fla.,
approximately 130 miles from the type locality) shows a row of six macro-
chaetae in the same position as that shown in E. ghesquierei and an inter-
nal line slightly anterior to the position of that shown in E. ghesquierei.
The tubercle on the edge of the paraproct and the surrounding hairs
(Fig. 4) of the E. pumilis specimens agree with Ball's figure (1943, Fig. 7)
as well as with his description of these features in E. ghesquierei. The
gonapophyses show a few slight differences (compare my Fig. 1 and 2
with Ball's Fig. 8). The terminal ciliation of the third valvula is subject
to a slight amount of variation. Ball illustrates a wide juncture between
the second and third valvulae. Although this does not exist in the speci-
mens which I have examined, the membrane of the second valvula is very-
thin in this region, and it would be easy to mistake an underlying structure
or a wrinkle in the cuticle for the edge of the valvula. In fact, Ball's figure
leaves some doubt about what the joining line between the two valvulae
actually does represent.
Measurements on the type of E. pumilis are as follows: forewing length,
1.30 mm; posterior tibial length, 0.52 mm; IO/D 2.7 (Badonnel Method);
width of head between eyes, 0.32 mm.

114 The Florida Entomologist Vol. 48, No. 2

Although there are minor differences between these measurements and
those presented by Ball for E. ghesquierei, they can scarcely be regarded
alone as delimiting distinct species.
In view of the above considerations, I regard these two species as the
same, and the name Ectopsocus ghesquierei Ball falls into the synonymy
of E. pumilis Banks.
RECORDS: United States: Florida-Gainesville; Monticello (type lo-
cality). Texas-San Antonio (plant quarantine interception from Marilia,
Sao Paulo, Brazil).
DISCUSSION: The species was recorded (under the name E. ghesquierei)
by Ball (1943) from several localities in the Congo (type locality, Eala).
A new Congo locality was added by Badonnel (1946). Pearman (1960)
recorded the species from Tanganyika, where it was collected on Rattus
rattus. Thornton (1962) recorded it from Hong Kong, where it was taken
in stored breakfast cereal in a private house. The latter author also cited
a personal communication from Mr. C. Tsutsumi of its collection in stored
products in Japan. The specimens from Gainesville, Fla., were collected
on a leather suitcase covered with mold in an apartment. The series con-
sists of thirty adult females and two nymphs. Males have never been
Thornton (1962: 298) states that the Hong Kong specimens differ from
those described by Ball in having the abdomen banded and in that the ocelli
are bordered in reddish. Although it was not possible to study these char-
acters on the type of E. pumilis "due to its condition, the specimens from
Gainesville, Fla., agree with Ball's material in these respects.
It would appear that the species has been spread rather readily by hu-
man commerce and that it is probably not native to Florida. The complete
absence of males in collections suggests the possibility of parthenogen-
Ectopsocus titschacki Jentsch (1939: 120)
Although Jentsch states in the original description that the type ma-
terial was apparently from Venezuela, no definite localities have been re-
corded for the species in the Western Hemisphere. Ball (1943: 11) indi-
cated the presence of the species in the Belgian Congo. Badonnel (1949:
44) recorded it from the Ivory Coast and described the male.
RECORDS: Brazil: Para-Belem. British Guiana: Georgetown. French
Guiana: Cayenne. Puerto Rico: Mayaguez; Rio Piedras. Surinam: Para-
maribo. Trinidad (WI): Piarco; Simla.
The above records represent field collections of the author. In addition,
the species was taken in plant quarantine at Mobile, Ala., on material
originating in Panama. The species is relatively common in the regions
indicated above in dry leaves on branches in disturbed habitats such as
botanical gardens and edges of cities.

Ectopsocus vachoni Badonnel (1945: 44)
Badonnel (1962: 223-224) has demonstrated the synonymy of this spe-
cies with E. dimorphus Mockford and Gurney, and has cited distribution
records from Morocco, France, Great Britain, southern United States, and
Argentina. Later (1963) the same author cited records from Chile. I
have taken the species from a number of Mexican localities.

Ectopsocopsis cryptomeriae (Enderlein)

Ectopsocus cryptomeriae Enderlein (1907: 100).

Thornton (1962: 294) has given a synonymy of this species complete
to its time and has indicated the likelihood of its synonymy with the spe-
cies described by Chapman (1930) as Ectopsocus pumilis (Banks), but,
as shown above, this is not the true E. pumilis (Banks). In fact, there
appear to be no differences between the species described by Chapman and
the true E. cryptomeriae Enderlein, as described in detail by Thornton
(1962), so that they must be regarded as the same. In the following ref-
erences to the species, the names indicated were used.

This species was originally described from Japan (type locality,
Kanagawa). It is frequently encountered in United States Department
of Agriculture plant quarantine inspections of material from Japan. In
view of this and the fact that there are no other known North American
species of its genus, it would seem likely that this species is not a native
of North America but may have been introduced in commerce from the
Old World. The species occurs throughout eastern United States from
Florida and Texas in the South to central Illinois and southern New York
in the North. It is established in the Monterrey region of northern Mexico
(personal observation).

The genus Kelerimenopon was erected in 1942 by Conci for K. sanfilip-
poi, described at that time for specimens taken off Pitta rufiventris, (Cabanis
and Heine). Hopkins and Clay (1952) included in the genus: (Colpoceph-
alum ciliatum Piaget 1880; Menopon griseum Piaget, 1885; Colpocephalum
longipes Piaget, 1880; and Colpocephalum minor Piaget, 1880. They com-
mented "There is greatest doubt about the group of hosts infested by this
genus, but some indications that the true hosts may be Megapodidae (see
Clay, 1949, Ann. Mag. Nat. Hist., (12), 2: 830). All the material is of very
doubtful provenance (almost all of it from museum skins) and the genus
is alleged to occur on almost as many groups of hosts as there are known
Three distinct groups of species are presently represented in the genus.
The species found on hosts of the genus Pitta have abdominal pleurites
II-VI with inner vertical projections.
The species found on hosts of the family Megapodidae have abdominal
pleurites II-V with inner, vertical projections, and abdominal pleurites
VI-VIII with inner horizontal projections. The species in this group are:
M. griseum, C. ciliatum, and C. minor.
The species found on hosts of the Psittaciformes have abdominal pleu-
rites without inner projections. The only described species in this group is
C. longipes.
There are many other differences between the groups, which suggest
that they are not congeneric. The species found on the host genus Pitta
are referred to Kelerimenopon s. str., and probably the genus should be
limited to these species. Detailed discussion of the groups found on the
Megapodidae and the Psittaciformes is deferred until more freshly-collected
material becomes available.

HOLOTYPE MALE: External morphology and chaetotaxy as shown in
Fig. 2. Male genitalia (less sac) as shown in Fig. 3. Total length, 1.32
ALLOTYPE FEMALE: External morphology and chaetotaxy as shown in

Discussion: This species is closest to K. sanfilippoi Conci, 1942; but
is separated from it by differences in chaetotaxy, the male genitalia, and
size. K. thompsoni has at least three long setae on each lateral margin of
the preocular region of the forehead, while K. sanfilippoi has only one in
these locations. The gular region has four long setae on each lateral mar-

gin in K. thompsoni, and three in K. sanfilippoi. The parameres of K.
sanfilippoi are slender distally, with a short thick base, in K. thompsoni
they are slender throughout their length.
The male and female of K. sanfilippoi have a total length of 1.00 mm
and 1.44 mm respectfully; being considerably smaller than K. thompsoni.
Type host: Pitta sordida (P. L. S. Millerr.
Type material: Holotype male, allotype female, and paratypes of
both sexes were collected by Max Thompson on Balabac Island, Philippines,
19 April 1962 (Bishop Museum Number PI-2508). Holotype and allotype
are deposited in Entomological Collection of the Bishop Museum. Para-
types have been distributed to other leading museums.

Erwin, Tennessee

Many species of phytoseiids prey on phytophagous mites and a large
amount of work has been done on the group because of their possible im-
portance as biological control agents. Except for the records of Phytoseiu-
lus macropilis (Banks) and Amblyseius evansi Chant, however, the phyto-
seiids that occur in Puerto Rico are unknown. This paper deals with the
species I collected when on the island between 23 Aug. and 5 Sept. 1963.
Twenty-three species were collected, 14 of which are new to science.
Of the 9 described species, 6 also occur in Florida, and 1 each in Mexico,
Trinidad, and Tortola (a small island east of Puerto Rico). These 9 species
are listed below in this order with collection localities and plants on which
they were found:
Amblyseius (Amblyseialus) largoensis Muma: Santurce on Cocos nucif-
era, Mangifera indica, Calophyllum antillanum, and Hura crepitans; Ponce
on Spondias dulcis; Salinas on Cordia sebestina.
Amblyseius (Typhlodromips) dentilis (DeL.): Santurce on Ipomoea
Iphiseius quadripilis (Banks): Santurce on Laguncularia racemosa;
Rio Piedras on a meliaceous tree.
Phytoseiulus macropilis (Banks): Santurce on Desmodium tortuosum.
Galendromus annectens (DeL.): Santurce on Hura crepitans; Ponce
on Guazuma ulmifolia.
Typhlodromina conspicuua (Garm.): Coamo on Sterculia apetala and
Tetrazygia eleagnoides; Juanadias on Hura crepitans; Cayey Mt. (elev.
about 1800 ft.) on Cordia sulcata.
Typhlodromina adjacentis (DeL.): Coamo on Colubrina reclinata; Cayey
Mt on Myrcia splendens, Cordia alliodora, and Polypodium phyllitida; El
Yunque (elev. about 2500 ft.) on Myrcia deflexa.
Phytoseius (Pennaseius) bennetti DeL.: Rio Piedras on Congea tomen-
tosa; Cayey Mt on Osmia odorata.
?Amblyseius (Amblyseius) herbicolus Chant: Santurce on Tabebuia
sp.; Rio Piedras on Faramea occidentalis, Lagerstroemia speciosa, Lantana
involucrata, Psidium guajava, and Palicourea riparius; Sabana on Andira
inermis. Setae L5 and L6 of these specimens show considerable variation
in length. In some, on one side L5 is as long as L6, on the opposite side
L5 is shorter than L6; in some L5 is scarcely shorter than L6 (10:12) and
in others L5 is distinctly shorter than L6 (8:13).
In the descriptions, I have followed Garman (1948) when designating
setae of the body as his system for the phytoseiids is simple and brief; for
the macrosetae of the legs, I have used the symbols employed by Athias-
Henriot (1957). In several of the new species, the ventral cuticula of the

specimens either stretched greatly or tore apart in the mounting process;
in drawing these specimens the 3 principal shields are shown in their ap-
proximately normal position, but the platelets and setae of the ventrolateral
area have probably been drawn much closer to each other than is normal
for them. The descriptions and drawings are of holotype females unless
otherwise indicated, and measurements are in microns. Leg measurements
are from base of coxa to claw end of pretarsus and tarsal measurements
include the pretarsus. The services of the spermathecae are all drawn to
the same scale and the lengths given for them include the atria.

Typhloseiopsis funiculatus, new species
(Fig. 1)

Typhloseiopsis funiculatus is readily distinguished from T. theodoliticus
DeL. by having the ventrianal shield fully developed, and from the species
placed in this genus by Schuster and Pritchard (1963) by having L2-L4
minute. The male is unknown.
FEMALE: Dorsal shield practically smooth, 317 long, 190 wide with
setae arranged as shown in Fig. 1. Lengths of setae as follow: L1 36,
L2 8, L3 7, L4 8, L5 34, L6 9, L7 7, L8 66; D1 23, D2-D6 7; M2 36; S1 12;
VL1 43. Sternal shield with 3 pairs of setae, but posterior margin not
clear; ventrianal shield 94 long, 74 wide (near anterior margin); only 1
metapodal shield, 20 long. Chelicerae poorly oriented, fd about 27 long
and apparently with 2 teeth near tip, md apparently with 3 teeth. Legs
too bent to measure; tarsus I 122, IV 141; sgel 16, II 23, III 28, IV 53, sti
29, st 49. Cervix about 18 long.
Holotype: Female, Coamo, P. R., 28 Aug. 1963 (D. De Leon), on Gym-

Typhloseiopsis regulars, new species
(Fig. 2)

Typhloseiopsis regulars is distinct from all other mites in this group
in having a notch in the dorsal shield behind L6 and a very long L8.
FEMALE: Dorsal shield smooth, 332 long, 271 wide with setae arranged
as shown in Fig. 2. Lengths of setae as follow: L1 42, L2 4, L3 10, L4 5,

date and locality as for holotype.

Amblyseius (Euseius) subalatus, new species
(Fig. 9)
Amblyseius (E.) subalatus is distinct from any other member of this
group in having S2 on the dorsal shield and in having the dorsal shield
abruptly narrowed at S2. In the type specimen S1 also appears to be on
the dorsal shield as indicated in the drawing; in the paratype specimen the
position of the setae is not clear, but they appear to be situated just off
the dorsal shield. The male is unknown.

an almost fully developed larva.

Amblyseius (Ricoseius) loxocheles, new sub-genus and new species
(Fig. 11)

This mite does not fit any of the established sub-genera because it has
3 pairs of setae lateral of the ventrolateral setae and leg IV with a macro-
seta on tibia only. The long setae of the dorsal shield, many of which are
capitate, and the very heavy chelicerae are also distinctive. Ricoseius is
proposed as a name for mites with these general characters with A(R.)
loxocheles as type.

Paraphytoseius santurcensis, new species
(Fig. 12)
Paraphytoseius santurcensis resembles P. multidentatus Swirski and
Shechter very closely; it differs from the description and drawing of that

Hibiscus tiliacea. Paratypes: 3 males, 6 females collected with holotype;
1 female on Hura crepitans, other data as for holotype.
These mites were common on H. tiliacea with 10 or more per leaf (the
leaves are large-about 7 inches across) and no other mites were seen on
the leaves. A pair appeared to be mating with the male on the back of the
female for a period of about 30 seconds and then the male left the female;
before this period the male clung to the female, struggled to get on her
back and appeared to be aggressive, after this period the male ignored her.
With the pairs of Amblyseius and Phytoseius that I have seen and thought
were mating the male was beneath the female and ventral side up.

Phytoseius (Phytoseius) woodburyi, new species
(Fig. 13)
Phytoseius woodburyi resembles P. macropilis (Banks) as redescribed
by Chant and Athias-Henriot (1960), differing from their description
chiefly in the relative lengths of the setae of the dorsal shield and in the
size and shape of the macrosetae. The male is not known.
FEFMALE: Dorsal shield 280 long, 147 wide with setae of the following
lengths: L1 32, L2 14 (smooth), L3 29, L4 10 (smooth), L5 117, L6 73,

Plantation Field Laboratory, Fort Lauderdale, Florida

A new fungicide mixture was observed to control tropical sod web-
worms in No-Mow bermudagrass, Everglades-1 bermudagrass, Tifgreen
bermudagrass, and Bitter Blue St. Augustinegrass in South Florida.
The initial observation was made on 11 June 1964, following the termi-
nation of a test of fungicides for control of Helminthosporium-Curvularia
infection of Tifgreen bermudagrass which was conducted at the University
of Florida Plantation Field Laboratory, Ft. Lauderdale, Florida. The treat-
ments could not be rated for disease control because the grass was eaten
off by tropical sod webworms, Pachyzancla phaeopteralis Guenee, in all
plots except those sprayed with PFL-64, which is a mixture of 3 parts 50%
Captan (M trichloromethyl thiotetrahydrophthalimide), 2 parts 53% Tri-
basic copper sulfate, and 2 parts 75% PCNB (pentachloronitrobenzene), and
those treated with Experimental Turf Fungicide-64, a mixture of 3 parts
65% Thiram (tetramethylthiuramdisulfide), 2 parts 53% Tribasic copper
sulfate, and 2 parts 75% PCNB.
Both these mixtures had been applied at the rate of 7 lb. per 100 gal-
lons of water per 1000 sq ff of turf. No sod webworms were found in the
grass in any of the replications of either of these treatments. There was
an average count of 20 webworms per sq ft of turf in all replications of
the other 13 treatments in the test. The color, ground cover, and over-all
appearance of the PFL-64 plots were outstanding, and the grass in the
Expt. Turf Fungicide-64 plots was almost as good.
To check on these observations, five additional tests were run on web-
worm infested plots of No-Mow bermudagrass, Everglades-1 bermudagrass,
and St. Augustinegrass. Single spray applications of PFL-64 at dosage
rates of 1%, 1%, 312, and 7 lb. of PFL-64 per 1000' sq ft of turf were
applied. Expt. Turf Fungicide-64 was not tested further as it was diffi-
cult to keep in suspension and to apply.
At all dosage rates, sod webworms were controlled for from four to
six weeks. A single application of PFL-64 at 11/ pounds per 1000 sq ft
on each of the three bermudagrasses, gave protection from sod webworms
for six weeks. At all dosage rates the grasses showed signs of new growth
within three or four days after treatment, and recovery continued through-
out the periods of observation.
Individual components and combinations of two components of PFL-64
were tested but did not give as effective control as did the complete
Further study of the effect of PFL-64 at smaller dosage rates is neces-
sary in order to learn the minimum effective dosage of this mixture for
the control of sod webworms in South Florida turfgrasses.
