INSECTS AFFECTING MAN AND ANIMALS

F. C. Bishopp, in Charge

The principal activities of this division in the field for the month
of February have been concerned with investigations of cattle grubs, R. W.
Wells left Washington February 8 for Galesburg, 111., to make observations
near there on seasonal abundance and stages of development of the cattle

grubs.

W. G. Bruce, assigned to the Fargo, N. D., field laboratory, ar-
rived there February 13 and took up his duties. The district, in the Red
River Valley of the North, where this laboratory is located is free from
cattle grubs, although grubby cattle have on various occasions been shipped
in. Mr. Bruce's problem is to determine what the factors are which apparent-
ly prevent the establishment of Hypoderma there, and his work is being
done in cooperation with the North Dakota Agricultural College. Prof.
J. A. Munro, of the Department of Entomology, Prof. J. E. Chapman, Depart-
ment of Agronomy, Dr. A. F. Schalk, Department of Veterinary Science, and
Prof. J. H. Shepperd, Department of Animal Husbandry, and others, of the
staff of the North Dakota Agricultural Experiment Station, have shown great
interest in the problem.

H. S. Peters left Dallas, Tex., February 3 by automobile for Ter-
re Haute, Ind. , and arrived there February 7, after making observations
on cattle grubs en route. After making stops in Columbus, Ohio, and Pitts-
burgh, Pa., he returned on February 17 to the field laboratory at Belts-
ville, Md., to which he is now assigned.

F. C. Bishopp left Washington February 8 to make observations at
various points on cattle grubs and to supervise the work of assistants in
the field. His first stop was Terre Haute, Ind.; from there he drove over-
land to Galesburg, 111., stopping en route at Urbana on February 11 for a
conference with Doctors Flint, Metcalf, and Graham, of the staff of the
Illinois Agricultural Experiment Station. On this date, at the request of
Dr. Graham, he gave a talk before the Illinois Veterinary Conference, which
was in session. Other points visited by him were St. Paul, Minn., Fargo,
N. D., and Lamar, Colo. At the place last named conferences were held with
officials of the Bureau of Animal Industry who are conducting there an
experiment in control of the cattle grub. Mr. Bishopp returned to Washing-
ton February 22.

Dr. L. 0. Howard addressed the New Jersey Mosquito Extermination
Association at Atlantic City, N. J., February 13, presenting his annual
summary of world-wide mosquito work.

EEE CULTURE INVESTIGATIONS
James I. Hambleton, in Charge

George H. Rea, who was formerly a special field agent of the Bee Cul-
ture Laboratory, recently stopped at the laboratory on his way to New Eern,
N. C., where he intends to engage on an extensive scale in queen rearing
and the production of package colonies of bees.

Prof. L. M. Bertholf, of Western Maryland College, Westminster, who
has been engaged in research at the Eee Culture Laboratory for several re-
cent summers, stopped at the laboratory on February 23 to complete some
work relating to a number of manuscripts which he is preparing for publi-
cation. While in Washington Professor Bertholf also consulted with mem-
bers of the scientific staff of the Bureau of Standards about his work
dealing with the response of honeybees to light of various wave lengths,
which he expects to resume at the Bee Culture Laboratory in the coming
summer.

Jas. I. Hambleton attended the meeting of the Southern States Beekeep-
ing Conference held at Baton Rouge, La., February 7, 8, and 9, where he
discussed the package-bee and queen-rearing industry. The meetings were
held in Agricultural Hall of the University of Louisiana, where the South-
ern States Bee Culture Field Station of the bureau is located. It was one
of the best meetings ever held by the Southern Conference, and beekeeping
representatives from most of the Southern States, as well as from a few of
the Northern States, were in attendance. One of the principal aims of the
Conference was to bring about, if possible, the standardization of packages
of bees. In order to expedite the establishment of standards the confer-
ence voted unanimously to leave the matter entirely in the hands of Doctor
Whitcomb and Doctor Oertel, of the Southern States Bee Culture Field Sta-
tion, who, after consulting with shippers and buyers of packages of bees,
are to draw up specifications which will be submitted to the trade for ap-
proval before being recommended as standard.

Mr. Hambleton also visited the bureau's Gulf Coast Laboratory, at New
Orleans, La., and the Texas Apicultural Laboratory, located about 15 miles
from San Antonio, where he discussed with H. B. Parks, the director of the
laboratory, various matters pertaining to beekeeping in the South, particu-
larly matters relating to honey-plant surveys. Mr. Parks has made a very
comprehensive study of the honey flora of Texas, and is considered the out-
standing authority on honey plants in the Southern States.

On the same trip Mr. Hambleton stopped at the Intermountain Bee Cul-
ture Field Station, at Laramie, Wyo., and discussed the experimental work
to be done there for the coming season. He spent a day at the Colorado
State Agricultural College, at Fort Collins, where problems in beekeeping
of the Intermountain States were discussed with Professor Richmond. The
Intermountain Bee Culture Laboratory has an experimental apiary located
just outside of Fort Collins, which was visited en route.

W. J. Nolan attended the meeting of the American Honey Institute on
February 6, and the convention of the American Honey Producers' League on
February 7, 8, and 9. Both were held in Sioux City, Iowa. The meetings
of these two organizations constituted one of the best and most important
gatherings of beekeepers held in this country in recent years. The atten-
dance, which came from 19 States, taxed the hotel accommodations. A sudden
spell of cold weather, however, kept away many beekeepers who were within
driving distance. There were present representatives of many State bee-
keepers* associations, and most of the large marketing organizations, such
as the Mountain States Honey Producers’ Association, the Colorado Honey
Producers' Association, and the recently organized Preserves and Honey, Inc.
The latter is a $5,000,000 organization for the marketing of honey and for
the promotion of various commercial interests, including the American Rail-
way Express Company and the Kellogg Company, commercial bottlers of honey,
and manufacturers of beekeepers' supplies and of tin and glass containers.

The American Honey Institute was organized in March, 1928, by the uni-
ted efforts of honey bottlers and manufacturers of beekeepers' supplies, for
the dissemination of information regarding honey, in order to increase its
consumption as a food by itself, and the demand for it in baking and in the
trade, and also to obtain information as to its value in the diet and other-
wise. Membership in the Institute is now open to all, whether individuals
or organizations, who are interested in the aims here set forth.

The convention of the American Honey Producers' League was given over
to general and business sessions. Talks were given on important questions
having to do with honey and its marketing, inspection work, and work in
special research. Mr. Nolan addressed the convention on results obtained
at the Bee Culture Laboratory confirming Doctor Watson's method for the ar-
tificial insemination of queenbees, and also on conditions relating to
the exportation of honey from the United States. At one of the evening
sessions a talk on the uses of honey was given by Dr. H. E. Barnard, pres-
ident of the American Honey Institute, which was broadcast. The Bureau of
Agricultural Economics sent its market-news specialist on honey, H. J, Clay,
to attend the convention. The State bee inspectors present created a new
organisation to be known as the Association of Apiary Inspectors of America,
the object of which is to further uniform practice in apiary inspection.

TROPICAL, SUBTROPICAL, AND ORNAMENTAL PLANT INSECT INVESTIGATIONS

A. C. Baker, in Charge

Appearing on the Program of the Central California Citrus School,
held at Portersville, Calif., E. A. McGregor spoke February 8th on the
subject "The Latest Word in Citrus Thrips Control." About 200 growers
attended this meeting.

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

The Modesto, Calif., News-Herald for January 11 and 12 carried sev-
eral interesting accounts regarding control of the bean weevil in Stan-
islaus, Merced, and San Joaquin Counties, and featured illustrations fur-
nished by A. 0. Larson and C. K. Fisher. Fifty ranchers residing in Merced
County met at Hilmar on January 14 and unanimously passed a resolution
favoring the adoption of a county ordinance providing for the destruction
of sources, in storage, of development of the bean weevil. Thanks to the
hearty support given by State and county agricultural agents, the principal
bean growers of this district are solidly behind the movement to control bean
weevils. A resolution was proposed the object of which was to retain in
this district the services of Messrs. Larson and Fisher.

Perez Simmons and W. D. Reed attended the 21st annual meeting of
the Dried Fruit Association of California, held January 10 to 12 at Del
Monte, Calif. Mr. Simmons read a paper entitled "Pest Control News."

Perez Simmons inaugurated on February 7 a periodical exchange for
1929 among the laboratories of the bureau on the Pacific Coast. Four-
teen laboratories are cooperating in the exchange, which includes 441 numbers
of 33 periodicals, mostly dealing with entomology or closely related sub-
jects. Among the publications thus made available to each worker are Biolog-
ical Abstracts, Quarterly Review of Biology, Review of Applied Entomology,
and Science News Letter. Those entering magazines in the exchange are Messrs.
Blanchard, Campbell, Cole, Doucette, Elmore, Keen, Lane, Larson, McGregor,
Newcomer, Rockwood, Shirck, and Simmons.

Visitors to the Dried Fruit Laboratory at Fresno in February num-
bered 25, and included Professor W. C. O'Kane, Messrs. G. J. Morton, E.
B. Russell, and W. C. Taber, of the San Francisco office of the Food, Drug
and Insecticide Administration, Professors Ralph E. Smith, H. N. Hansen,
and I. J. Condit, of the University of California, E. P. Roleson, chemist,
California Packing Corporation, and C. E. Scott, Office of Plant Pathology,
California State Department of Agriculture.

On February 21 Dr. Back gave an informal talk on control of fab-
ric pests at the National Institute of Cleaners and Dyers, at Silver Spring,
Md. Men attend this institute from all parts of the country, many being
sent at the expense of the firms by which they are employed.

On January 7, at the request of a large dried-fruit packing house,
W. D. Reed was in San Francisco to attend a demonstration of a new ex-
periment for vacuum fumigation, estimated to have cost $20,000. D. B.
Mackie, of the California State Department of Agriculture, who is a col-
laborator of the bureau, and also a representative of business firms, was
present .

On January 15 to 18 W. D. Reed tested the new fumigating chamber
constructed in the San Jose plant of the California Packing Corporation.
Liquid hydrocyanic acid, ethylene oxide, and a proprietary fumigant were
used.

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

On February 19, at Spokane, Wash., E. J. Newcomer, in charge of the
field laboratory at Yakima, Wash., for investigations of the codling moth,
met with representatives of the Washington Experiment Station and the Wash-
ington State Department of Agriculture to formulate recommendations for
State control of the codling moth in 1929.

T. L. Bissell, until recently of the pecan-insect field laboratory
at Barnesville, Ga., which has been discontinued, is now in immediate charge
of pecan-insect investigations at Experiment, Ga,, where laboratory facil-
ities have been provided by the Georgia Agricultural Experiment Station.

G. F. Moznette, in charge of pecan-insect investigations, attended
the meetings of the Cotton States Branch of the American Association of
Economic Entomologists held at Houston, Tex., February 6 and 7, where he
presented a paper on "Airplane dusting experiments, and results secured
for the control of the pecan leaf case-bearer." Others present from the
Division of Deciduous-Fruit Insects were 0. I. Snapp, of the field labo-
ratory at Fort Valley, Ga., and C. C. Pinkney, of that at Brownwood, Tex.
Mr. Snapp was elected secretary-treasurer, and B. R. Coad, in charge of
the Division of Cotton Insects, chairman, of the Cotton States Branch.
After the meetings Mr. Moznette visited the field laboratory at Brown-
wood, and that at Shreveport, La,, and conferred with various men who are
working on pecan insects. Mr. Snapp, with several State entomologists,
made a trip into the lower Rio Grande Valley of Texas to observe some of
the work being done on the Mexican fruit worm and in inspection at points
on the Mexican border.

TAXONOMIC INVESTIGATIONS
Harold Morrison, in Charge

George H. Harrington, an oil geologist associated with the Standard
Oil Company, and who for several years was located in northwestern Argentina,
recently called at the National Museum and donated to it a large number of
Argentinian and Bolivian beetles which he had collected during the past
decade. Many of these were taken by him in the course of geological in-
vestigations along the Rio Beni, and consequently are an important supplement
to the collection of beetles from the same region made by Dr. W. M. Mann
cn the Mulford Biological Expedition in 1921 and 1922.

A. B. Gahan has recently been the recipient of two important ship-
ments of the C. F. Baker collection, including specimens that had been sent
by Professor Baker tc specialists for study. Dr. G. Grandi, Instituto di
Zoologia, R. Universita, Bologna, Italy, sent a number of specimens of fig
insects, among which are several types of new species described by him.
Dr. L. Masi, Museo Civico di Storia. Naturale, Genoa, Italy, returned a por-
tion of the material of the family Chalcididae. Several types of Dr. Masi's
new species were included in this consignment.

Late in February J. C. Elmore, of the Garden Grove, Calif., field
laboratory of Truck Crop Insect Investigations, consulted with Dr. A. G.
Boving and Mr. H. S. Barber regarding some of the descriptions of the stages
of species which he is considering in his manuscript on the pepper weevil,
Anthonomus eugenii.

ganization. It was very well attended by scientists and commercial shade-
tree men. A. F. Burgess, formerly of the bureau, and now with the Plant
Quarantine and Control Administration, was elected vice-president for the
year. Many interesting papers were presented, covering the subjects of case
records, callus healing, aeration of tree roots, tree injection, oil-spray
problems, fertilization of trees, and a series of papers on both insect
pests of trees and fungus growths of trees. H. J. MacAloney prepared a
paper on the white pine weevil as a pest of shade trees for presentation at
the conference.

C. W. Collins, of the Gipsy-Moth Laboratory, was in Washington Feb-
ruary 18 to 21 to confer with Dr. Craighead, and with Doctors Marlatt and
Quaintance and Mr. Graf, regarding the work of the Laboratory. After leav-
ing Washington he made a short visit to the Japanese Beetle Laboratory.
