INSECTS AFFECTING MAN AND ANIMALS

F. C. Bishopp, in Charge

August, 1928

On August 4 W. E. Dove and Frank Adams were the victims of a tragic
'accident which resulted in the death of Mr. Adams. They were returning
to their station at Uvalde, Tex., from a trip in an automobile to a near-
by mountain canyon. In crossing what is usually a dry stream bed they
encountered a sudden rush of water caused by a cloudburst higher up in
the mountains. Both men and the car were swept down stream by the force
of the water. Mr. Dove, by great good fortune, managed to lay hold of the
branches of a tree, and some hours later was rescued from this position.
Mr. Adams was not seen alive after the water struck the car. His body
was found the next day, some distance below the river crossing.

Mr. Adams was a temporary field assistant at the time of his
death, and was assisting Mr. Dove in studies of goat lice. He held the
degree of Master of Science from the Southern Methodist University,
located at Dallas, Tex. He was a careful and conscientious worker and
showed great promise as an entomologist.

On August 29 F. C. Bishopp and Dr. Marion Imes, of the Bureau of
Animal Industry, left Washington on a trip to points in New York State,
to investigate possible sites for cooperative work on control of cattle
grubs, to be shared by the Bureau of Entomology and the Bureau of Animal
Industry.

Wesley G. Bruce has accepted an appointment as Assistant Entomol-
ogist, and will be assigned to work on cattle grubs, with headquarters at

Fargo, N. D.

R. A. Roberts has accepted a temporary appointment as Field As-
sistant, and will be assigned to the field laboratory at Uvalde, Tex.

C. E. Abbott, a Junior Entomologist at the Dallas, Tex., labora-
tory, has resigned, effective August 31.

This Division was represented at the Fourth International En-
tomological Congress at Ithaca by F. C. Bishopp and W. V. King, both of
whom presented illustrated papers. The title of Mr. Bishopp 's paper was
"The cattle-grub (Hypoderma) problem from an international point of view."
Doctor King's paper was entitled "On the development of malaria parasites
in the mosquito host."

DECIDUOUS-FRUIT INSECT INVESTIGATIONS
A. L. Quaintance, in Charge

G. F. Moznette, in charge of the pecan insect laboratory at Al-
bany, Ga., spent August 1 to 4 at Spring Hill, Ala., near Mobile, con-
ducting control experiments with the black aphid of the pecan, Myzocallis
fumipennellus Fitch, which has been causing serious damage to pecan trees
in the vicinity. The feeding of this aphid leads to defoliation.

G. F. Moznette reports that the two recent tropical disturbances
which swept through Georgia did considerable damage to the pecan crop.
The loss per tree will average from 1 to 4 pounds, depending on the age
of the tree. Under some large trees from 500 to 600 nuts have been gath-
ered from the ground.

John F. Fayne . pilot of the Tallulah, La., field laboratory, spent
Aiugust 8 and 9 in airplane dusting of pecan trees at Albany, Ga. , in co-
operation with G. F. Moznette.

During the week of August 6 to 11 H. S. Adair, in charge of the
pecan insect field laboratory at Brownwood, Tex., visited Houston, Tex.,
and collected some pecan material there, finding that damage by the nut-
case bearer had been unusually heavy. The laboratory at Brownwood re-
ceived some material from there earlier in the season, and a number of
hyperparasites were reared. These insects may account for the heavy
infestation in the vicinity of Houston in the present season. One grower
estimated his loss at about 90 per cent of a full crop, and similar
damage was reported by others. On his return trip from Houston to Brown-
wood, Mr. Adair stopped at the Texas A. « M. College, College Station,
and conferred with the Experiment Station entomologists and extension
workers who are especially interested in pecans.

C. H. Phipps, Associate Entomologist, Dr. H. C. Hildreth, Hor-
ticulturist engaged in blueberry investigations, and Robert Chandler,
Assistant Horticulturist, all of the Maine Experiment Station, Prof. K.
H. Salman, of the Department of Entomology, Massachusetts Agricultural
College, Warren Pettigrew, of the Maine State Department of Agriculture,
and C. W. Collins, of the Gipsy Moth and Brown-tail Moth Investigations,
Bureau of Entomology, visited the blueberry maggot field laboratory,
Cherryfield, Me., late in July and early in August.

On August 14, Fred E. Brooks, in charge of the field laboratory,
at French Creek, W. Va., visited Washington on business relating to his
work on nut insects.

C. T. Blanz, a resident of Washington, D. C., has been given tem-
porary appointment to assist in investigations and control of nut weevils
in the government chestnut orchard at Bell, Md.

Prof. Bernard Trouvelot, entomologist at the Institut des Recher-
ches Agronomiques, at Versailles, France, visited the field laboratory at
Yakima, Wash., on August 27 and 28.

In the codling moth work at the Yakima field laboratory during the
years 1922 to 1928, inclusive, 180 laboratory tests of ovicides have been
made, using a total of more than 50,000 codling moth eggs. In the same
period 900 laboratory tests of larvicides have been made, using 4,500
apples and 45,000 hatched larvae.

Dr. A. L. Quaintance attended the Fourth International Congress
of Entomology, at Ithaca, N. Y. , and read E. J. Newcomer's paper on
"Codling Moth Conditions in the Northwest," Mr. Newcomer not being able
to be present.

Dr. Lon A. Hawkins, Physiologist, of the Bureau of Plant Industry,
visited the field laboratory at Yakima, Wash., August 10. A. Lloyd
Ryall, Junior Pomologist, working under the direction of Dr. Hawkins, is
quartered at the Yakima field laboratory for cooperative work in connection
with the problem of spray residues.

B. E. Montgomery, who has been serving as Field Assistant at the
field laboratory at Vincennes, Ind. , during the summer, resigned August
31. He has accepted a graduate assistanship at the Iowa State Agricultural
College, at Ames, and is to work there for his doctorate.

Dr. B. A. Porter, of the Vincennes, Ind., field laboratory, at-
tended the International Congress of Entomology, held at Ithaca, N. Y.,
August 12 to 18, and presented a paper discussing the problem of the
codling moth, as it exists in America at the present time.

Dr. B. A. Porter also attended the summer meeting of the Indiana
State Horticultural Society at Evansville, Ind., August 2, and the meeting
of the Kentucky State Horticultural Society at Henderson, Ky., August 3.
At the latter meeting the oriental peach moth, which has recently ap-
peared in southern Indiana and western Kentucky, was informally discussed.

Contributions from the Japanese Beetle Laboratory

On August 14 Loren B. Smith presented a paper on the Japanese
beetle at the meeting of the Fourth International Congress of Entomology
at Ithaca, N. Y.

C. H. Ballou, of the Japanese Beetle Laboratory, served as official
Spanish interpreter at the Fourth International Congress of Entomology.

Centeter cinerea Aldrich, the introduced tachinid parasite of the
adult Japanese beetle, was released in large numbers during July and
August at Bridgeport, Conn., Harrisburg, Pa., and Noble, Pa. Following
the release of the flies many beetles were recovered upon which eggs had
been deposited.

The colony of the Japanese wasp Tiphia popilliavora Rchwer, estab-
lished near Riverton, N. J., has more than maintained its vigorous condi-
tion. During August sufficient adults were present to permit the release

- 4 -

of 18 additional colonies. A total of 28 subcolonies in all have been
released from the parent colony. A recent check-up of the points where
colonies of this insect were set free in 1927 revealed the fact that the
10 subcolonies are all well established.

Conditions in the central portion of the area heavily infested by
the Japanese beetle indicate a slight reduction in the population of the
beetle, as compared with conditions during the last four or five years.

Foreign visitors in August at the headquarters of the work on the
Japanese beetle, at Moorestown, N. J., included J. C. F. Fryer, of the
Ministry of Agriculture, and Dr. A. D. Imms, of the Rothamstead Experi-
ment Station, Harpenden, Herts, England; Dr. Bernard Trouvelot, Institut
des Recherches Agronomiques, Paris, France; Dr. Filippo Silvestri, Regio
Institute Superiore d ' Agricoltura, Portici, Italy'; Dr. Martin Schwartz,
Director Biologische Reichsanstalt fur Land- und Forstwirtschaft, Berlin-
Dahlem, and Dr. K. W. Baunacke, Abteilung fur Pf lanzenschutz der Stat-
lichen Landwirtschaftlichen Versuchsanstalt, Dresden, Germany; Dr. Jar-
omir Samal, of the University of Prague, Czecho-Slovakia; and Dr. Karl
Knechtl, Zoological Laboratory, University, Bucharest, Rumania. From
Ontario were C. S. Thompson, of the Ontario Department of Agriculture,
and A. B. Baird, of the Entomological Branch, both from Chatham. Visi-
tors from the United States included S. M. Dohanian and D. W. Jones, of
the laboratory for corn-borer research at Arlington, Mass., Mr. and Mrs.
B. D. Van Buren, Department of Agriculture and Markets, Albany, N. Y. ,
Don C. Mote, of the State Agricultural Experiment Station, Corvallis,
Oreg., S. E. Flanders, Saticoy, Calif., and 0. H. Swezey, Honolulu,
Hawaii .

Members of the Fourth International Congress of Entomology made
an official trip to the headquarters of the work on the Japanese beetle,
at Moorestown, N. J., Monday, August 27. Upon arriving at the laboratory
the guests were shown informally the work in progress under the several
projects. Especial interest was shown in the constant-temperature ap-
paratus used in connection with the studies of soil insecticides. Two
hot-water baths were in operation, each having a capacity of 300 gallons,
and arranged for automatically maintaining constant temperatures. Of
particular interest also were a vacuum and pressure tank used in studying
problems relating to fumigation, chemical laboratories for special prob-
lems, the parasite cellars, where the temperatures and. the humidity are
made to correspond to the temperatures and moisture of the soil, electri-
cal traps, and other equipment. Unfortunately, the delegates had to en-
train for New York shortly after noon, and it was therefore impossible
for them to spend more than a very brief time on any particular phase of
the work. About 32 delegates were present. Those who registered from
abroad included Dr. Bledowski, of Poland, Dr. Vayssiere and Dr. Regnier,
of France, Dr. Stellwaag and Dr. Skwarra, of Germany, Dr. G. Fox Wilson,
of England, Dr. N. A. Kemner, of Sweden, Dr. Streda, of Hungary, Dr.
Damph, of Mexico, Dr. Efflataun, of Egypt, Dr. Thomsen, of Denmark, Dr.
Roepke, of Holland, Dr. N. M. Rimsky-Korsakov and Dr. Saitzev, of Russia,

- 5 -

and Dr. and Mrs. Saalas, of Finland. From our own country were registered
W. W. Chapman, Miss A. Franklin, and S. C. Harris, Philadelphia, Pa.,
Prof. H. J. Quayle, Riverside, Calif., and I. L. Ressler, New York City.

FOREST-INSECT INVESTIGATIONS
F. C. Craighead, in Charge

Dr. F. C. Craighead attended the Fourth International Entomological
Congress, held at Ithaca, N. Y., from August 12 to 16. He presented a
paper on "The organization and activities of the division of forest in-
sects," and also a summary of J. M. Miller's paper on "Barkbeetle epidemics
in relation to windfalls."

William Middleton also attended the Congress from August 14 to
IS, and presented a paper entitled "Factors influencing the activity of
shade-tree insects and the utilization of these in control work."

Dr. T. E. Snyder likewise attended the Congress from August 12
to 18. He presented a paper entitled "Termites modify building codes,"
at the sessions of the section of forest entomology. A fairly large
representation of the workers on termites of the world were in attendance
at these meetings.

Dr. S. A. Graham, of the University of Michigan, an agent of this
office, also attended the Congress, and presented a paper on "The larch
sawfly in forestry."

Another attendant at these meetings was H. J. MacAloney, of the
field laboratory at Amherst, Mass.

The special sessions on forest insects were very well attended.
Sixty-five American and European forest entomologists and foresters were
there, and many exceptionally interesting papers were presented, two of
them by members of the United States Forest Service. E. N. Munns, in
charge of the Forest Service Experiment Stations, read a paper on "Sil-
vicultural practices in the control of forest insects," and Philip Wake-
ley, of the Southern Forest Experiment Station at New Orleans, La.,
presented a paper on the pine tip moth, Rhyacionia f rustrana Comst.

At the close of the last special session on forest entomology a
vote of thanks was extended to Professor Glenn Herrick for the splendid
program he had prepared and for the assistance and the many courtesies
that he had rendered those attending. A motion was carried requesting
that the special session on forest entomology be made a permanent part
of the Congress.

COTTON-INSECT INVESTIGATIONS
B. R. Coad, in Charge

On August 15 B. R. Coad, in charge of the field laboratory at
Tallulah, La., with R. E. Mitchell, pilot, took off for El Paso, Tex.,
in the newly purchased Stinson Detroiter airplane, en route to Tlahaulilo,
Mexico, where he will inaugurate studies of the migration of the moth of
the pink bollworm.

- 7 -

Another pilot and a mechanician accompanied Mr. Coad, they flying
one of the DeHaviland airplanes of the field laboratory fleet, which will
be used as an auxiliary and supply plane for the Stinson plane. The
Stinson plane is equipped with insect traps for capturing pink bollworm
moths in flight. Lieutenant pilot aviator Jose Leon, of the Mexican
Aviation Service, convoyed Mr. Coad and party in the flight from El Paso
to Tlahaulilo on August 22. Dr. F. A. Fenton and G. W. Berrier, of the
pink bollworm field laboratory at El Paso, Tex., and P. A. Glick, of the
laboratory at Tallulah, who made the trip to Tlahaulilo by train, complete
the staff of workers who will conduct the investigations of the pink
bollworm in Mexico.

Joseph E. Culpepper, Robert P. Patty, and Bertram A. Moers, tem-
porary field assistants at the Tallulah field laboratory, resigned in
August and returned to college.

At the Fourth International Congress of Entomology, held at Ithaca,
N. Y., August 12 to 18, there was a sub-section on cotton insects, of which
Prof. J. M. Robinson was chairman. Prof. J. Gray vice chairman, and Dr.
J. W. Folsom secretary. The attendance numbered 31, and much interest
was manifested. Dr. C. L. Marlatt opened the session with an informal
talk on the present status of the pink bollworm in the United States and
Mexico. Five papers were presented by their authors, as follows: F. G.

BEE CULTURE INVESTIGATIONS
James I. Hambleton, in Charge

Dr. A. P. Sturtevant, in charge of the United States Inter-moun-
tain Bee Culture Field Laboratory at Laramie, Wyo., spent several days
in the week of August 20 at the Bee Culture Laboratory, Somerset, Md. ,
conferring with members of the staff about the work of the Laramie Sta-
tion. He left to return to his station on August 27. While here Doctor
Sturtevant also made a study of septicemia, a disease of adult bees re-
cently discovered by Dr. C. E. Burnside. It is thought that this disease
also exists in the Intermountain States.

Dr. Martin Schwartz, Reichministerium fur Ernahrung und Landwirt-
schaft, Berlin-Dahlem, Germany, visited the Laboratory on August 11.

Miss Winifred S. Hull, temporarily employed as Field Assistant
at the Bee Culture Laboratory, resigned on August 25 to resume her studies
at the Medical School of Johns Hopkins University.

Apicultural Section, Fourth International Congress of Entomology

Jas. I. Hambleton, Dr. C. E. Burnside, Dr. L. M. Bertholf, and
Miss Ethel L. Coon, of the Bee Culture Laboratory, at Somerset, Md. ,
and Dr. A. P. Sturtevant, of Laramie, Wyo., attended the Fourth Interna-
tional Congress of Entomology, at Ithaca, New York, August 13 to 18.
Dr. Burnside, Dr. Bertholf, and Mr. Hambleton presented the following
papers, respectively: "A septicemic condition of adult honeybees," "Re-
actions of light in honeybees," and "Apparatus for measuring the flight
activity of honeybees."

Dr. Lloyd R. Watson, formerly of the Bee Culture Laboratory, but
now with the Genetics Department, Cornell University, gave several demon-
strations of the artificial insemination of honeybees, which were very
well attended by members of the congress.

A paper presented by Dr. A. G. Lochhead, Central Experimental
Farms, Ottawa, Canada, on "Studies on the Etiology of European Foulbrood,"
aroused much interest. Dr. Lochhead shewed that cultures of Bacillus
alvei under certain conditions transform into a symplasm from which
develop colonies of bacteria to all appearances identical with Bacillus
pluton . This strongly indicates that Bacillus alvei and Bacillus pluton
are the sa,me organism, and if Dr. Lochhead succeeds in infecting healthy
colonies of bees with a growth of Bacillus pluton which he secures from
his cultures of Bacillus alvei there will be no doubt that the two or-
ganisms, heretofore considered entirely distinct, are one and the same.

- 9 -

Doctor Burnside's paper on septicemia brought out the interesting
and rather unusual fact that the causative organism named by him. Bacillus
apisepticus , enters the bee through the respiratory system, and not through
the alimentary tract.

S. H. Skaife, of the Department of Public Instruction, Capetown,
Union of South Africa, gave an interesting account of beekeeping in South
Africa. He stated, among other things, that their two common races of
honeybees are not the same as those occurring in the United States. He
emphasized the precautions that are being taken in South Africa to pre-
vent the entry of American foulbrood. This disease does not occur there
at the present time, and for this reason all foreign importations of honey
and bees are prohibited.

A number of excellent papers by Russian investigators were pre-
sented, among which may be mentioned those of Dr. W. W. Alpatov, of the
University of Moscow, on "Variations in honeybees from the theoretical
and practical points of view," Prof. A. F. Gubin, Odinzowo, Moscow, on
"The work of the Moscow Apicultural Experiment Station," and A. Skorikov,
of the State Institute for Experimental Agronomy, Leningrad, on "The
employment of Caucasian bees in the fertilization of red clover." In
this paper was reported the finding of some Caucasian bees with tongues
considerably longer than the tongues of the average Italian or German
bees .

Ethel Ronzoni and Dr. George H. Bishop, of the Washington Univer-
sity School of Medicine, St. Louis, Mo., presented a paper on "Sugar
metabolism in honeybee larvae."

Doctor Bertholf, in his paper on "Reactions of light in honey-
bees," showed that the stimulating efficiency in the spectrum for honey-
bees is almost the same as that for humans, reaching its maximum in the
yellow-green. In the shorter wave-lengths the efficiency for bees is
considerably higher than for humans. The converse is true for long waves.

Dr, Louis Bahr, Bakteriologisk Laboratorium, Ratin, Copenhagen,
brought up for discussion the establishment of an international be-e-
journal, to record research in the field of apiculture, both from the
scientific and the purely practical points of view. Another matter
brought up for discussion was the advisability of the affiliation of the
Apis Club, an international apicultural organization, with the Interna-
tional Congress of Entomology. If this were done the Club would still
continue to hold its annual meetings in England, as in former years, but
in addition would hold an international meeting at each time and place
that the Congress meets.

One of the special social features of the Congress for those in-
terested in apiculture was a picnic for the Section of Apiculture, ar-
ranged by Dr. E. F. Phillips and his students, which was held on Thursday
evening in the rear of Roberts Hall. About sixty persons were in attend-
ance .

ington August 20, after spending six months in Peru. Mr. Shannon will be
in the Museum about six weeks, working up some insects collected in con-
nection with his investigations of verruga fever— a disease known only in
Peru.

The members of the Taxonomic Investigations who attended the Fourth
International Entomological Congress at Ithaca, N. Y. , August 12 to 18,
were Dr. H. Morrison, Dr. A. G. Boving, Dr. C. E. Mickel, August Busck,
A. B. Gahan, Carl Heinrich, Miss Grace Glance, and Miss Louise Russell.
