AN ENTOMOPHTHORA ATTACKING CITRUS RED MITE
FRAN. E. FISHER 1
Florida Citrus Experiment Station, Lake Alfred
One of the most serious pests of Citrus in Florida is the
citrus red mite, Paratetranychus citri (McG.), which is com-
monly known in this state as the purple mite. Although this
mite has been known in Florida since before 1885 [Riddle (5)],
only during the past two decades has it assumed major import-
ance in all of the citrus areas in this state. Because red mites
have a short life cycle and are small in size, heavy infestations
can build up quickly and rather inconspicuously. Mites may
be found at almost any season of the year, but the damage they
cause is negligible until they become abundant. These pests
attack the leaves, young twigs, and fruit causing an injury which
is grayish in color. This damage is difficult to measure or esti-
mate unless there is a leaf drop. During the fall, winter, and
spring months, the injury caused by heavy infestations has, at
times, resulted in a heavy leaf drop in many groves.
In 1944 Thompson (14) pointed out that sulfur sprays had
been effective in upsetting the natural balance of control of red
mites, and that reinfestations of these mites were frequently
more severe following a sulfur spray than in adjacent non-
sprayed control plots. Previously, Thompson (13) had reported
that red mites became more abundant following copper sprays
than where no copper had been applied. In 1948 Thompson and
Stearns (15), in a comparison of two post-bloom sprays, showed
that the amount of copper deposited from a copper-wettable
sulfur spray was, on the average, 1.8 mcg/cm2 whereas a copper-
oil spray resulted in an average deposit of 3.4 mcg/cm.2 Six
months after these sprays the red mite infestations were 8 per-
cent and 59 percent respectively. He suggested (14) the possi-
bility that fungicidal sprays retarded the effectiveness of any
entomogenous fungi that might be present.
Although a survey of the available literature has failed to
show that a specific fungus has been found to be associated with
red mites, the mites have been reported to disappear during the
summer and early fall months (6, 14). These epizootics have
in the main been attributed to high temperatures (6, 14) or to
The writer is indebted to Dr. R. M. Pratt for valuable suggestions and

unknown causes (4). Griffiths and Thompson (3) reported four
insect predators, a trash bug, an aphis-lion, and two ladybeetles,
as being predaceous on red mites in Florida. They concluded
that counts made on these predators could not be satisfactorily
correlated with increases and decreases of infestations, and that
there was apparently some other factor which played an im-
portant role in the natural control of red mite infestations.
In 1948, the writer observed fungus hyphal bodies and rest-
ing spores in red mites. However, the material was not sufficient
to determine the identity of the fungus. In August of 1950
this fungus was observed again in our laboratory by Miss Jean
Linebaugh. Since that time specimens have been numerous and
all stages of parasitism have been found. This endoparasitic
fungus attacking red mites has been identified as Entomoph-
thora sp.
The genus Entomophthora belongs to the order Entomoph-
thorales and to the class Phycomyceteae. According to Bessey
(1), "some species of this genus are called Empusa by some
writers, but since this name was used earlier for a genus of Or-
chids the next later name, Entomophthora, must be used." The
members of this genus are all parasitic within insects (1) and
were long thought to be obligate parasites. However, several
species have been grown in culture (7, 8, 9 and 10). Probably
other species will be induced to grow in culture when the proper
media and conditions are provided.
A number of species of Entomophthora are economically im-
portant. Among these are E. muscae on the common housefly,
Musca domestic Linn.; E. grylli on grasshoppers; and E. fumosa
attacking the citrus mealybug, Pseudococcus citri Risso. Speare
(11) has reported that in Florida E. fumosa was unquestionably
the major factor in the natural control of the citrus mealybug.
The species of Entomophthora attacking red mites is similar to
E. fumosa, but does not appear to be the same species.
In general, species of Entomophthora infect insects by the
penetration of the integument and the appendages (12). After
the conidium germinates and the germ tube penetrates into the
body cavity, the hypha forms thick segments which break apart
from one another. These are the hyphal bodies which multiply
and which dissolve the internal organs of the host, presumably
by enzymes which the fungus secretes (1). After the insect is
dead and the food supply depleted, the hyphal bodies may de-
velop in one of two ways. Under unfavorable environmental
VOL. XXXIV, No. 3 SEPTEMBER, 1951
conditions, the hyphal bodies may develop thick walls and form
resting spores (2). Under favorable conditions the hyphal
bodies form conidiophores which emerge through the integument
of the insect and produce conidia. As the conidium matures,
the conidiophore and the conidium absorb water. Finally a
strong pressure is developed which causes the conidium to be
violently discharged into the air. If the conidium fails to strike
an insect it may germinate forming a secondary conidium which
is, in turn, discharged. This process may take place until a
host is located or the protoplasm in the conidium is exhausted.
In some species true zygospores may be formed, but in others
the resting spores are asexually developed.
Red mites infected with Entomophthora may show one of
several external manifestations. The first indication of disease
can be determined in living mites by observing the movement
of the adult mite. In all cases, to date, mites which move slowly
in a staggering or weaving manner have been found to be in-
fected with hyphal bodies. These mites may contain from 2 or
3 long-ovoid hyphal bodies to a larger number which fill approxi-
mately one-half of the body cavity. Mites which have recently
died appear normal at first glance, but do not move when touched
with a needle. These mites have been found to be completely,
or almost completely, filled with hyphal bodies. No remaining
part of the internal organs can be distinguished, but the red
pigment is still present and is distributed throughout the body
between the hyphal bodies.
Mites killed by the fungus generally exhibit one of two ap-
pearances. If favorable development of the fungus has taken
place, the body of the mite will be somewhat distended, cheesy
in consistency, and dark red or dark purple in color, occasionally
with a grayish tinge. These mites usually show some stage of
conidiophore development. The grayish tinge if present, is in-
dicative that the fungus is mature and that conidia have been
produced by the conidiophores. Under unfavorable conditions,
mites contain resting spores, are usually very hard when cut
with a needle, and are dark purple to black in color. These
mites are generally a little smaller than normal or hyphal-body-
filled mites; rarely are they distended.
Figure 1 shows a side view of an adult, dead, red mite which
was killed by Entomophthora sp. It should be noted that the
conidia which are just outside of the integument are formed
THE FLORIDA ENTOMOLOGIST
on the dorsal side of the mite. To date the formation of directly-
ventral conidiophores and conidia has not been found.

Although this disease is more prevalent and the fungus de-
velopment is more typical in adult mites than in younger stages,
it has been found to attack deutonymphs. No visible infection
has been found in protonymphs.
This species of Entomophthora has been found throughout
peninsular Florida, south of Mount Dora to Avon Park and from
VOL. XXXIV, No. 3 SEPTEMBER, 1951 87
east of Tampa to Fort Pierce. All examinations of heavy mite
infestations in groves between these points have shown the
disease to be present. Because of this occurrence in groves
scattered over such a wide area, it is probable that the fungus
is present throughout the citrus belt.
During September and October, counts made in groves with
heavy infestations showed adult mortalities ranging from 32
to 95 percent. In October four counts were made in a Temple
grove near Tampa in order to learn more about the mortality
of the population as the various generations matured. Table 1
shows the percent infestation in this grove, the percent adults,
and the percent mortality of adult mites due to Entomophthora
sp. It is interesting to note that during the period of highest
mortality, the percent of leaves infested was the lowest. No
predators were found during this period of observation.

Additional study of this disease will be necessary in order
to determine its importance in the biological control of red mites.
The climate, Entomophthora, and the various predators un-
doubtedly have interacting effects on the red mite infestations.

CHECK LIST OF THE SYRPHID FLIES (DIPTERA:
SYRPHIDAE) OF FLORIDA
HOWARD V. WEEMS, JR.
Department of Zoology and Entomology, Ohio State University
The family Syrphidae comprises one of the few large families
of flies which, viewed from an economic standpoint, are of great
benefit to man. The larvae of a considerable number of species
are aphidophagous, destroying countless numbers of plant lice
and other injurious insects which suck the juices of plants. In
many areas syrphid larvae are a principal natural control of
aphids on truck crops and citrus. The adults commonly visit
flowers for nectar and serve an important role in effecting cross-
pollenation of plants. Only a few species accidentally introduced
into the United States from Europe are known to be harmful,
feeding on bulbs of narcissus, amaryllis and onion, and none of
these is known to occur in Florida. There are a few authenti-
cated records of accidental parasitism in man, but these are
of little significance. Certain species of syrphids have been
used by scientists in the laboratory in the study of the physiology
of insects, in genetics, and in cytology. Many are of value as
scavengers, consuming decaying animal and vegetable matter
which otherwise would be a nuisance to man.
Adult flies present a remarkable diversity of size, form, and
coloration, some resembling bees, wasps, and bumblebees so
closely that they are frequently mistaken for the latter. Many
species are brightly striped, banded, or otherwise colored with
yellow, orange, green and blue, and range from relatively smooth,
shiny species to several which are densely hairy. In some cases
even the eyes are densely pubescent.
The only check list of the Syrphidae of Florida was published
in 1913 by C. W. Johnson and included 21 genera and 56 species,
several of which were incorrectly determined. There has been
relatively little work done in Florida on this interesting family
of flies since that of Johnson. I began a study of the Syrphidae
in 1945, and have collected a sufficient number of species to
warrant publishing this list which includes 103 species, in 32
genera. Records are included from the U. S. National Museum,
American Museum of Natural History, Academy of Natural
Sciences of Philadelphia, Ohio State University Museum, Ohio
State Archaeological and Historical Society Museum, Illinois
THE FLORIDA ENTOMOLOGIST
Natural History Survey collection, Emory University Museum,
and from a survey of published records in the literature. Fur-
ther collecting, undoubtedly, will add a fair number of species
to this list. Apparently, there has been no collecting done in
northwestern Florida, and only casual collecting in other parts
of the state. Present records indicate that other species re-
corded from Cuba and the West Indies will be found on the
southern-most part of the mainland and on the Florida keys.
To attempt at this time to map the distribution of each species
would be premature, since careful collecting has been done in
only a few localities.
This list compares favorably with those for other states.
Hull (1947) lists 105 species in 45 genera for Mississippi. Brim-
ley (1938, 1942) records 128 species in 42 genera for North
Carolina, which has been intensively collected by Metcalf, Shan-
non, and others. Smith (1909) lists 132 species in 45 genera
for New Jersey. Britton (1920) lists 112 species in 41 genera
for Connecticut. Metcalf in a 1913 list, to which many species
have been added in recent years, shows 114 species in 35 genera
for Ohio. Telford (1939) lists 135 species in 52 genera for
Minnesota.
I have collected Syrphids principally in north-central Florida
around Gainesville, in south-central Florida around Sebring,
Highlands Hammock State Park, Lake Placid, and Clewiston,
and southward from Miami to Key West. Plans for the future
include concentrated collecting west of Tallahassee. At some
future time I plan to publish a key to the Syrphidae of Florida
as well as descriptions of several new species which I have col-
lected in Florida. It is hoped that this list will stimulate interest
in the family which will result in the discovery of new state
records.
Locality records for each species are listed in order beginning
with northwest Florida and proceeding eastward to Tallahassee
and Jacksonville, then southward. Specimen records for each
locality are listed in sequence, beginning with the earliest date
and proceeding to the most recent. For each specimen, all
available information is given in the following order: locality,
date, collector, host plant, determiner, number of specimens hav-
ing duplicate data, source of record (if taken from the litera-
ture), and location of the specimen(s). In each record where
the number of specimens is not given, only one is indicated.
VoL. XXXIV, No. 3 SEPTEMBER, 1951
All specimens listed were seen by me with the exception of
some specimens recorded by Johnson and Williston which are
not located now in the American Museum of Natural History,
United States National Museum, or Academy of Natural Sciences
of Philadelphia. Florida specimens in my collection total 516;
a total of 1453 specimens taken in Florida was examined in
compiling this check list.
Unless otherwise indicated, I am responsible for the identifi-
cation of any material in my collection; Dr. C. H. Curran is re-
sponsible for determination of material in the American Museum
of Natural History; Dr. R. C. Shannon, Dr. J. R. Malloch, Mr.
C. T. Greene, and several others are responsible for determina-
tion of material in the United States National Museum; Dr. R. C.
Osburn is responsible for determination of material in the Ohio
State University collections; Dr. C. L. Metcalf is responsible for
determination of material in the Illinois Natural History Survey
collection; and Dr. E. T. Cresson and others are responsible for
determination of material in the Academy of Natural Sciences
of Philadelphia. In taking the data from specimens in these
collections, I have checked determinations, and the few correc-
tions which were made have been indicated in this paper. Re-
sponsibility for determination of species records taken from
the literature lies with the authors of such publications. Many
of my specimens were sent to Curran, Fluke, and Hull for de-
termination or check on my determinations, especially where
a probable new species was involved. Where records are from
the literature, location of specimens is not known unless it is
so indicated. I have followed Hull's (1949) arrangement of
genera and subgenera. Mr. Erdman West, botanist and mycolo-
gist at the University of Florida, determined plant hosts of
numerous specimens which I took.

THE FLORIDA ENTOMOLOGIST
A COMPARISON OF THE COST OF SPRAYING CITRUS
TREES UTILIZING TWO DIFFERENT SPRAY MACHINES *
H. A. THULLBERY
Superior Fertilizer Company
The spraying of citrus groves is a costly operation. Many
years of research have been spent in attempting to devise less
costly spray programs, both by altering the use of the various
materials and by changing to different kinds of equipment. In
1948 the author (1) discussed the entire cost of production prob-
lem in 33 groves which were directly under his supervision. In
that study total costs varied between 29 cents and 43 cents per
box. Of this charge, the spray program consumed between
8.1 and 11.40 per box. Approximately half of this cost was
for material and half for labor and operational cost of equipment.
During most of the 1948 operation complete cost figures were
kept for two spray machines. One was a Model JXD Speed
Sprayer with a 500 gallon tank. The second machine was a
standard hand sprayer with a 600 gallon tank.
The Speed Sprayer operation involved the use of two 500
gallon truck supply units and a tractor to pull the sprayer. The
three drivers in this operation received 80 cents per hour. The
hand machine was mounted on a truck. The driver received 80
cents and the two spray hands 70 cents per hour.
An accurate check of the gasoline and oil consumption of
all of these pieces of equipment was kept in addition to an ac-
count of all repairs. By using the standard cost accounting
procedures of the employing firm, depreciation figures on the
equipment were also available.
Table 1 presents a summary of data obtained in this study.
Several factors are outstanding. The Speed Sprayer applied
the spray at a slightly lower cost per gallon in the over-all opera-
tion; however, it was considerably cheaper when only the cost
of labor, gas, and oil were considered. It was the depreciation
and repairs on the several pieces of expensive equipment which
ran up the costs of the Speed Sprayer operation.
This study points up one of the major advantages of using
a mechanical sprayer like the Speed Sprayer. It was able to
apply two and one-half times as many gallons per hour as the
hand machine. Thus, one Speed Sprayer could do as much work

as two and one-half hand machines when three men were em-
ployed in both operations. It would do this at a slightly lower
cost, but the biggest advantage would be a saving in time. This
allows greater elasticity in planning spray operations and per-
mits the owner to time sprays properly. Also it will tend to
prevent the situation where large acreages need spraying and
there is insufficient time to do the job.
SUMMARY AND CONCLUSIONS
The costs of running a Speed Sprayer were compared with
those of a standard orchard hand spray machine for one year's
operations in citrus groves in Florida. The Speed Sprayer
applied two and one-half times as many gallons as the hand rig
at a cost of .475 cents per gallon. The cost per gallon for the
hand machine was .547 cents.

THE FLORIDA ENTOMOLOGIST
NOTES ON NORTH AMERICAN SPECIES OF PTEROBOSCA
O. A. JOHANNSEN
Cornell University
In the December number of the Florida Entomologist (33:
141-144, 1950) mention is made of two defective specimens of
Pterobosca from Puerto Rico that were not described. Recently
I was fortunate enough to find in the Cornell University col-
lection two more specimens in good condition of the same species
and from the same locality. The species, named P. incubans by
Macfie, was originally recorded from British Honduras. It is
a small form chiefly black in color, the feet without claws, the
fourth tarsal segment somewhat shorter than the fifth, and
with but a single spermatheca.
To Macfie's description (Proc. R. Ent. Soc. London, 6:111,
1937) may be added:
The eyes are sparsely and short haired; the palpi are a scant 0.1 mm.
in length, the last three segments having lengths in proportion to each
other of 7 5 6, the third segment swollen and with a large sense pit,
last segment slender and tapering, terminating in a few long hairs. The
antenna is 0.3 mm. in length, the ratio of the length of segments 10 to
15 combined to length of segments 3 to 9 combined is about 2.4; the latter
segments disc-like, transverse. Wing length 0.7 to 0.9 mm., width 0.3 to
0.35 mm. Hind basitarsus averages 3.5 times longer than the second seg-
ment. The empodium is large, three-fourths as long as the fifth segment,
complex, with 10 or 11 rays, resembling that of P. aeschnosuga, as figured
by Macfie (Tijdschr. v. Ent. 75:268. 1932). Length of insect 1.4 mm.
Macfie's statement that the eyes are bare is incorrect. Speci-
mens in the U. S. National Museum that were collected in Mexico
and determined by Macfie as P. incubans have pilose eyes, the
pile visible under a magnification of 400 to 500 diameters,
especially distinct when the specimen is first treated with
caustic potash.
The type described by Macfie was found on the wing of
Argia ulmeca. Specimens examined by me were collected by
Dr. J. G. Needham at L. Tortuguero, Puerto Rico, on February
10 and March 21, 1935, and from Leres, P. R., in March, 1935.
the hosts are Erythrodiplax umbrata and Lepthemia vesiculata.
For the privilege of examining the Mexican specimens men-
tioned above, I am indebted to Dr. W. W. Wirth of the U. S.
National Museum.

Pterobosca floridana Joh. Fla. Ent. 33: 143, 1950.
Dr. W. W. Wirth of the U. S. National Museum called my
attention to the fact that the species described by Coquillett
under the name of Ceratopogon fusicornis is a Pterobosca and
pointed out that P. floridana Joh. and probably also P. macfiei
Costa-Lima are synonymous with fusicornis. It appears that
the degree of variation in the antennal and tarsal ratios among
individual specimens is too great to warrant the use of these
ratios as diagnostic specific characters.
Since the publication of the account of this species in the
December number of this journal I have found on the wings of
dragonflies in the Cornell University collection three more speci-
mens in better condition which enable me to add the following
data:
The antennal ratio is 3.1, the same as for the specimen described in the
above mentioned article. Both the thorax and the abdomen are sparsely
beset with black bristles of varying lengths. The spermathecae, short
oval in form, are two in number. The basistyle of the hind leg is about
three times as long as the second tarsal segment. The dragonflies upon
which these specimens were found were collected by Dr. J. G. Needham.

Pterobosca sp.
A Puerto Rican species taken from the wing of Lepthemia
vesiculosa resembles the African P. mollipes Macfie in size, in
lacking claws, in having two spermathecae, and in having a sense
pit on the third palpal segment, but differs in antennal and
palpal proportions, and somewhat in wing venation. The speci-
men is broken and lacks most of its legs but the attention of
collectors is called to it because of its habitat. It may prove
to be but a variant of P. mollipes. The most striking differ-
ences are the relative lengths of the last three palpal segments
(7- 6 9.2), the greater antennal ratio (2.5), and in the wing
venation, the anterior branch of the media ending before the
wing tip.
The dragonfly host was collected by Dr. J. G. Needham at
L. Tortuguero, Puerto Rico, March 21, 1935.

BOOK NOTICES
A FIELD GUIDE TO THE BUTTERFLIES OF NORTH AMERICA,
EAST OF THE GREAT PLAINS, by Alexander B. Klots. xvi + 349
pages, 8 figures, 40 plates. 1951. Houghton Mifflin Company, Boston.
Price $3.75.
This most recent addition to Houghton Mifflin's Field Guide
Series is the outgrowth of many years of study of the Lepidop-
tera by Dr. Klots. The author has applied the Field Guide
system to his treatment, bring the butterfly taxonomy up to
date, and includes much information on distribution and life-
histories. Of the species treated, 247 are illustrated by color
paintings and 232 are shown in black-and-white photographs.
There are sections on collecting and preserving specimens, the
butterfly and its environment, life histories and growth, classi-
fication, and identification. Three appendices include some prin-
ciples of classification, butterfly literature and collections, and
a checklist of butterflies and skippers. The book admirably ac-
complishes its purpose of putting pertinent information into a
form that will be most useful to the novice as well as to the
more advanced student. Dr. Klots' book is well written and
beautifully illustrated.-L. B.
