MONTHLY LETTER OF THE BUREAU OF ENTOMOLOGY
UNITED STATES DEPARTMENT OF AGRICULTURE

Number 174

October, 1928

DEATH OF DOCTOR SCHWARZ

To the great loss of the science of Entomology, Dr. E. A. Schwarz
died on October 15th, The Entomological Society of Washington has spread
the following statement upon its minutes:

"The Entomological Society of Washington appreciates to the full-
est degree that in the passing of Dr. Eugen Amandus Schwarz it has lost
its most learned member, its most loyal and generous supporter and the
kindliest and most helpful of friends. The Society points with pride to
the facts that Doctor Schwarz was one of its founders, that he held in
the course of the years every office in which he could serve, and that
the title Honorary President was created especially for him.

"The Society feels that American entomologists should be grateful
that this great soul has lived among them for more than fifty years,
constantly in his quiet way influencing their trend of thought towards
the very best methods and towards sound scholarship."

INSECTS AFFECTING MAN AND ANIMALS
F. C. Bishopp, in Charge

On October 3 this office received a visit from three Russian en-
tomologists, A. P. Adrianov, Senior Specialist, Bureau of Plant Protec-
tion, V. V. Nikolsky, Entomologist, Interdepartmental Quarantine Commis-
sion, and J. A. Parfentier, Entomologist, Insecticide and Fungicide
Laboratory, all of the U. S. S. R. They were interested in basic in-
formation about the pink bollworm, to be used for its bearing on the
quarantine against the pink bollworm in their own country.

On October 22 D. C. Parman left Uvalde, Tex., for Thermal, Calif.,
where he spent the remainder of the month in a study of control measures
for the gnat Hippelates flavipes .

E. C. Cushing spent the month of October in making a mosquito
survey of northern Florida.

BEE CULTURE INVESTIGATIONS
James I. Hambleton, in Charge

Dr. Everett Oertel has been appointed an Assistant Apicultur-
ist to fill a vacancy in the Southern States Bee Culture Field Labora-
tory, recently established at Baton Rouge, La. He will devote his time
largely to the study of floral sources of nectar, manipulation of
bees, and other factors closely related to the production of honey.

Dr. Warren Whitcomb, Jr., of the Southern States Bee Culture
Field Laboratory, Baton Rouge, La. , attended the meeting of the Geor-
gia State Beekeepers' Association at Macon, Ga. , on Sept. 19, where
he outlined the work of that laboratory.

R. S. Kifer, of the Bureau of Agricultural Economics, visited
the Bee Culture Laboratory on Oct. 2 to confer with members of the
staff previous to his departure for the Intermountain States, where
he will continue the studies on the cost of producing honey and meth-
ods of apiary management upon which E. L. Sechrist, of the Bee Cul-
ture Laboratory, has been engaged during the past summer. Mr. Kifer
will make the final visit to all cooperators and close the work for
the season.

The American Honey Producers' League sponsored an exhibit of
honey which was shown at the annual convention of the American Die-
tetic Association, which met October 29 to 31 at the Willard Hotel.
The success of the exhibit was in large part due to Dr. E. N. Cory,
Secretary of the Maryland State Beekeepers' Association, who detailed
members of the association to take care of the display. The colored
poster advertising honey, published by the Bureau of Entomology, was
conspicuously displayed, and the staff of the Bee Culture Laboratory
assisted in the arrangements.

In the July News Letter mention was made of the fact that at
the time granulated honey was discovered in the apiary of the Bee Cul-
ture laboratory the bees were found to be working largely on sweet
clover. Since that time it has been determined that the granulation
of the honey was due to the presence of melezitose, one of the rare
sugars, and it is quite evident now that the bees had finished working
the true source from which the melezitose was derived, which was probably
the scrub pine, a tree occurring in abundance in this part of the
country. For this reason it has been impossible to determine defin-
itely whether the melezitose was derived directly from an exudation
of the scrub pines, or from honeydew collected from aphids.

Recent visitors at the Bee Culture Laboratory included Dr. W.
W. Alpatov, of the University of Moscow; Mr. Victor M. Buck, of the
Presbyterian School, Ebolowa, Cameroun, West Africa; and Dr. J. A.
Nelson, of Mt. Vernon, Ohio, who was formerly connected with the
laboratory.

- 3 -

Prof. H. F. Wilson, head of the Department of Entomology at the
University of Wisconsin, Madison, and also custodian of the Dr. C. C.
Miller Memorial Library located there, visited the Bee Culture Labo-
ratory on October 23. After looking over the library of the Division
of Bee Culture Investigations he deplored the fact than many valuable
and almost unobtainable books were housed in such an inflammable
building. Noticing many of the gaps in the volumes of bee journals,
he generously offered to transfer some duplicate material from the
Miller Library to that of the Bee Culture Laboratory, as he fully
agrees that the Department of Agriculture should possess the best
possible beekeeping library.

CEREAL AND FORAGE INSECT INVESTIGATIONS
W. H. Larrimer, in Charge

The alfalfa weevil field laboratory at Salt Lake City was
visited early in September by Dr, Filippo Silvestri, Portici, Italy,
and Professor Felipjez, Leningrad, Russia.

On September 15 Dr. J. C. Hamlin and M. M. Darley, of the
alfalfa weevil field laboratory, returned to Salt Lake City after a
ten-day study of conditions prevailing in alfalfa meal mills in west-
ern Nevada.

On September 21 L. Dean Christenson terminated his appoint-
ment as Junior Entomologist at the alfalfa weevil field laboratory,
to take up graduate studies at the University of Minnesota.

On September 17 Geo. I. Reeves and I. M. Hawley conferred with
Dr. P. V. Cardon, Dr. H. J. Frederick, and Dr. William Peterson,
Director, all of the Utah Experiment Station, at Logan, on matters
relating to arsenic poisoning.

W. H. Larrimer, in charge of Cereal and Forage Insect Inves-
tigations, spent October 25 to 30 at the field laboratory at Arling-

Lake City and Logan, Utah, October 18 to 22, and conferred with Feder-
al entomologists regarding the alfalfa weevil, and with Dr. B. L.
Richards, of the Utah Experiment Station, concerning a new and seri-
ous disease of potatoes, apparently transmitted by a psyllid hereto-
fore of little economic importance.

On October 4, at the request of Nevada State officials, S. J.
Snow investigated severe injury to corn, caused by the red spider, at
Hiko, Nev. He also spent much time investigating the presence of
alfalfa weevils on the premises of the meal mill at Fallon, Nev,

COTTON-INSECT INVESTIGATIONS

B. R. Goad, in Charge

The latter part of October marked the completion of a research
expedition to the Laguna District of Mexico which was started about
the middle of August. It was undertaken primarily for the purpose of
studying the flight habits and possible migration of the pink boll
worm. The expedition included two airplanes equipped for insect col-
lection and, as personnel, B. R. Goad, F. A. Fenton, P. A. Glick, G.

C. Berrier, G. C. McGinley, R. L. Mitchell, and R. G. Long. Con-
trary to previous belief, it was found that there is a distinct mi-
gratory period for these moths toward the end of the season. Indi-
viduals were collected at various altitudes up to 3,000 feet, and
were traced northward in the direction of the cotton areas along the
Rio Grande. After the studies in Mexico were completed, air-current
surveys were made by plane throughout the territory between Marfa,
Tex., and Tucson, Ariz. Trap-crop and similar records, made at the
same time along the American side of the border, showed the arrival
of a heavy migration of moths.

On the whole, the expedition was very successful, but was
marred by one unfortunate accident. It proved impossible to se-
cure suitable aviation gasoline in the portion of Mexico where the
majority of the flying was done, and, rather than fail to secure the
needed records, flying was continued with gasoline of very low
grade, the flyers realizing fully that the venture was exceedingly
hazardous. As a result, one plane was crashed in a forced landing
near Tlahualilo, Durango, with serious injuries to Pilot G. C.
McGinley and Entomologist P. A. Glick. Fortunately, both are now
well on the road to complete recovery.

D. A. Isler, Agent, with the Plant Quarantine and Control
Administration, has been assigned to this division for cooperation
in investigations of the pink bollworm in western Texas, in an
attempt to improve methods of plowing as a measure for winter con-
trol. This work is being conducted in cooperation with the Division
of Agricultural Engineering, Bureau of Public Roads.

F. M. Koler has been employed as Mechanical Engineer and
assigned to the pink bollworm project, to study improved methods
of disposal of gin waste. This work is also being done in coopera-
tion with the Division of Agricultural Engineering.

Norman S. Pearse, Assistant Secretary, International Federa-
tion of Blaster Cotton Spinners' and Itonufacturers ' Associations of
Manchester, England, was a visitor at the field laboratory at Tal-
lulah on October 27. Mr. Pearse was especially interested in the
problem of the pink bollworm.

- 5 -

Dr. W. E. Hinds, State Entomologist of Louisiana, while on a
tour of the State to investigate the present status of the boll wee-
vil, spent October 15 at Tallulah.

On October 4 R. G. Long, Airplane Mechanic, and P. A. Glick, of
the field laboratory, returned to Tallulah from Tlahualilo, Durango,
Mexico.

V. V. Williams, who has been conducting experimental work on
control of the boll weevil in Oklahoma during the past season, in co-
operation with the State Experiment Station and the Oklahoma Exten-
sion Service, returned to Tallulah on October 27.

R. W. Moreland, who has been conducting experimental work on
control of the cotton boll?/orm in the vicinity of Bryan, Tex. , during
the recent season, returned to Tallulah October 1.

The appointment as temporary field assistants of John S.
Graham and C. C. McCall expired in October.

S. W. Simmons and J. W. Yates were appointed in October as tem-
porary field assistants.

STORED-PRODUCT INSECT INVESTIGATIONS
E. A. Back, in Charge

In September George W. Ellington secured over 100,000 eggs of
Sitotroga cerealella for shipment to the Barbados Department of Ag-
riculture, for use in rearing Trichogramma parasites of Diatraea
saccharal i s . These eggs were taken to New York by Dr. R. T. Cotton,
and placed on the S. S. Voltaire, which sailed September 15. On
October 24 R. W. Tucker, Government Entomologist, notified Dr.
Quaintance that about 75 per cent of the eggs had hatched success-
fully. The eggs were laid between small strips of heavy paper, in
accordance with the method used by Simmons and Ellington during their
investigation of Sitotroga cerealella at Sligo, Md.

The Cappell Upholstering Company, of Dayton, Ohio, through
the National Association of Upholstered Furniture Manufacturers,
wrote this office on October 29 requesting 1,000 reprints of the
paper entitled "Tobacco Beetle as a Pest of Furniture." During the
past three years the tobacco beetle has been sent to the Bureau of
Entomology, as a pest of overstaffed furniture, from nearly every
State in the Union.

During the months of September and October Messrs . Larson and
Fisher, of the bean weevil field laboratory at Alhambra, Calif.,
have been overloaded with samples of beans taken from warehouse re-
ceipts in Merced and Stanislaus Counties. Warehousemen take no action
until a report on the status of the samples as regards the bean weevil
has been made by the laboratory. The Bureau is receiving excellent
cooperation from persons growing and warehousing beans in this region.

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

At the request of the Forest Service and the Southern Pacific
Railway, Dr. H. E. Burke made an examination in the latter part of
September of a severe defoliation on Douglas fir caused by a species
of Ellopia on the Cloudcroft reserve in the Sacramento Mountains in
New Mexico. The possibility of spraying or dusting 500 acres to pro-
tect this timber is under consideration.

F. P. Keen has completed a regional survey of the barkbeetle
infestation in the Klamath region of southern Oregon and on the Modoc
National Forest, California. About October 15 he undertook the super-
vision of the work of marking the infested timber on 15,000 acres
within the Modoc Forest, belonging to the Forest Service and a large
timber-holding corporation. The private operator has purchased gov-
ernment timber, and will begin a salvage logging program on both his
timber and that of the Government. This operation was planned not
only to salvage very severe losses that have already been incurred,
but also to attempt control by logging as rapidly as possible the in-
fested and susceptible trees on a considerable area.
