FOREST INSECT INVESTIGATIONS

F. C. Craighead, in Charge

Dr. F. C. Craighead spent three days in Denver, Colo., in the
latter part of April, conferring with J. M. Miller and J. C. Evenden .
Plans were arranged for the conduct of investigative work for the com-
ing summer and for the carrying on of certain projects in cooperation
with the Forest Service. As a result of the increase in appropriations
for the Division of Forest Insects for the coming fiscal year, a new
field laboratory will be established at Portland, Oreg. , with F. P.
Keen in charge.

At the present time considerable interest is manifested in the
widespread destruction being wrought by termites to the foundations
and interiors of buildings in all parts of the country, especially in
the Central and Southern States. A recent survey of the buildings in
Memphis, Tenn., by city officials, indicates that from 60 to 70 per
cent of them are infested by termites. Similar reports are being re-
ceived from New Orleans, La., and other cities in the Southern States.

Officials in the various cities are cooperating with the Bureau
of Entomology in effecting the control of termites in buildings. In
most instances the entrance of the subterranean type of termites into
foundations is due to improper methods of construction. To rectify this
situation the bureau is recommending brief suggestions for inclusion in
mandatory city building codes.

Recent visitors to the Gipsy-Moth Laboratory have been William
H. Thorpe, Demonstrator in Entomology, Zoological Laboratory, Cambridge,
England, April 2, and H. B. Peirson, Forest Entomologist of Maine, R. L.
Taylor, graduate student, Bussey Institution, Forest Hills, Mass., and
W. A. Baker, Bureau of Entomology, European Corn Borer Laboratory, Mon-
roe, Mich., April S.

A shipment of approximately 30,000 cocoons of the oriental moth,
Cn idee amp a flavescens Walk. , reached the Gipsy Moth Laboratory on April
23. These were collected in Japan by T. R. Gardner, of the Japanese
Beetle Laboratory, Yokohama, through the cooperation of Dr. A. L. Quain-
tance and Mr. L. B. Smith. The oriental moth is well established in
Boston, Mass., and vicinity, having been first observed there in 1906.
Rather large collections of larvae and pupae made in recent years have
indicated that parasism there is negligible; and the shipment of cocoons
from Japan was made as an attempt to establish where needed in this
country parasites that attack it in the Orient, especially a tachinid,
Chaetexorista ,i avana B. & B.

script on the effects of rainfall and temperature on the winter survival
and spring emergence of the Mexican bean beetle at various altitudes and
in different life zones. En route to Estancia he visited the field lab-
oratory for the study of cotton insects at Tallulah, La.

R. E. Campbell, in charge of the field laboratory at Alhambra,
Calif., reported that during the period April 8 to 15 G. A. Dean, F. C.

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

0. I. Snapp, in charge of peach-insect investigations at Fort
Valley, Ga., writes that the present curculio infestation in the Georgia
peach belt is the heaviest in eight years. A vigorous campaign of sup-
pression is being waged in order to control the second generation, v/’nich
will attack the matured fruit. A heavy infestation was anticipated, on
account of the quantity of wormy peaches left in the orchards last year,
and the low mortality of adults during hibernation.

Contributions from the Japanese-Beetle Laboratory

W. A. Baker, of the field laboratory at Monroe, Mich., for the
study of the European corn borer, visited the Laboratory on April 21 to
study the various methods used in rearing parasites of the Japanese
beetle .

Lead arsenate, in the form of a top dressing, applied to turf
for the control of Japanese beetle larvae, is being extensively used in
the infested area this spring. On the Lansdowne, Pa., golf course the
putting greens were treated with it in the autumn of 1928 and again in
the spring of 1329. Lead arsenate was applied at the rate of 3 pounds
to 1,000 square feet for each treatment. Examination of the turf on
April 30 revealed no living larvae. The degree of infestation in the
autumn of 1928 was more than 35 larvae to each square foot.

Loren B. Smith was recently elected President, and C. W. Bailey
Secretary-Treasurer, of the Federal Business Association of Camden, N. J.
This Association has jurisdiction over all Federal activities located in

TROPICAL, SUBTROPICAL, AND ORNAMENTAL PLANT INSECT INVESTIGATIONS

A. C. Baker, in Charge

In company with Dr. C. L. Marlatt, Dr. A. C. Baker left Wash-
ington, D. C., on April 9 to confer with officials of the Florida State
Plant Board concerning the recent outbreak of the Mediterranean Fruit
Fly. Dr. Baker is now giving special attention to investigations which
are necessary in the program of eradication.

On April 16, during the noon hour, E. A. McGregor spoke over
K F I at Los Angeles on the subject "The Citrus Thrips and Its Control."
This is probably the most powerful broadcasting station on the Pacific
Coast, and the reception was clear at least as far as Lindsay.

During the latter half of April The Western Dusters, a commercial
company, have been cooperating with E. A. McGregor in applications of
sulphur by airplane for the possible control of the citrus thrips. The
preliminary calculations of the expected destruction of citrus thrips by
this method seem to give considerable promise.

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

Carl Heinrich, of the Taxonomic Unit, sailed from New Orleans
on April 12 for Guatemala, to investigate reported occurrence of the
European corn borer in that country, and to study related species of
Pyrausta and their parasites. He will be absent about ten weeks.

W. A. Baker, of the field laboratory at Monroe, Mich., spent
April 8 to 10 at the headquarters for corn-borer research, at Arlington,
Mass.

Lowell A. Woodbury was appointed on April 2 as Field Assistant,
for duty at the field laboratory at Salt Lake City.

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

Gilbert A. Schenk, Associate Entomologist, who has been con-
ducting at Manhattan, Kans., the bureau's work on flour-mill insects,
resigned his position April 30, to engage in the ' commercial manufac-
ture of fumigants, with headquarters at Kansas City.

A business firm in California has recently written to A. 0. Larson,
of the field laboratory for dealing with bean weevils, at Modesto, Calif.,
"Please permit me to congratulate you and your able assistant, Mr. Fisher,
in the splendid work that your office has been doing in the control of
bean weevil in this country. We have not received even one complaint or
rejection from purchasers of beans on account of weevil this past season
and we deem this entirely due to your method for control at harvesting.
Many San Francisco dealers advise us the same experience. With the co-
operation, this coming season, of San Joaquin and Merced Counties we look
for much less evidence of the pest. Both of you gentlemen must have
exercised considerable diplomacy to hold the good wil? of the growers
and the assistance of warehousemen and dealers. Let the good work pro-
ceed."

BEE CULTURE INVESTIGATIONS
James I. HambXeton, in Charge

Miss Malitta D. Fischer, of the American Honey Institute, Indian-
apolis, Ind., visited the Bee Culture Laboratory on April 1 to 3.

W. D. Achord, of Findlay, Ohio, and Fitzpatrick, Ala., one of the
pioneer breeders of bees in combless packages, and a queen breeder of
note, while on his way from the South to Ohio visited the laboratory
April 26, to discuss methods of shipping bees and the standardization of
combless packages.

Richard B. Gregg, of Chestnut Hill, Mass., formerly of Simla
Hills, India, was a recent visitor at the laboratory. He has been suc-
cessful in the difficult task of importing Italian bees from England
into India. Since his return from India, however, he has received word
that these bees have been destroyed by predatory wasps or hornets, a
serious pest to bees in India. Mr. Gregg said that the production of
honey in India is very small, because the native hive bee (Apis .indioa)
stores only a few pounds of honey per colony. In order to increase the
production of honey there he is anxious to introduce the bee Apis mel-
lifica.

- 8 -

Dr. E. F. Phillips, of Cornell University, Ithaca, N. Y., spent
several days at the laboratory early in April, consulting material in
the bibliography.

E. R. Root, senior member of the A. I. Root Co., Medina, Ohio,
visited the laboratory April 18 to discuss various beekeeping matters.
He has recently made extended studies of beekeeping in California, Mexico,
and Central America.

Mr. and Mrs. Clyde V/heeler, commercial beekeepers, of Oberlin,
Ohio, visited the laboratory April 2. Mrs. Wheeler (nee Iona Fowls)
was formerly connected with the A. I. Root Co., of Medina, Ohio. Her
father was one of the pioneer beekeepers in Ohio. Mr. Wheeler produces
honey of high grade, and was awarded first prize on comb honey at the
Ohio State Fair in 1927..

COTTON INSECT INVESTIGATIONS
B. R. Coad, in Charge

On April 13 R. C. Gaines, of the field laboratory at Tallulah,
La., and T. P. Cassidy, in charge of the field laboratory at Tucson,
Ariz., conferred at Stillwater, Okla., with representatives of the Okla-
homa Agricultural and Mechanical College, on plans for cooperative work
on control of the boll weevil in Oklahoma in 1929. It was agreed that
four phases of the work should be carried on. 1. The Bureau of Ento-
mology will cooperate with the Oklahoma Experiment Station and Extension
Service in making control tests at three points in the infested area.
2. The Department of Entomology of the Experiment Station will conduct a
series of similar experiments in cooperation with local farmers in many
different counties. 3. The Extension service will conduct a large num-
ber of demonstrations of methods of control in counties where there are
infestations, using methods of control recommended by the cooperating
agencies. 4. At weekly intervals during the season the bureau will make
records of infestations through the infested territory, and the records
will be considered and analyzed by a central committee at the College.
Recommendations for control, based on these records, will be made by the
Extension Service and promptly forwarded through regular channels to the
localities concerned.

H. C. Young, of the field laboratory at Tucson, Ariz., reached
Tallulah, La., on April 22, for conference with reference to cooperative
work in Oklahoma.

On April 20 J. R. Douglass, of the Mexican Bean Beetle Field Lab-
oratory, Estancia, N. M. , visited the field laboratory at Tallulah, for
information on dusting machinery.

Dr. W. S. Hinds, Entomologist, Louisiana State Experiment Station,
visited Tallulah early in April for a conference with B. R. Goad,

Three patents and a patent on a process, all concerning the drying
of seed cotton, have been received in April at the division's headquarters
at Tallulah. The investigations on cotton drying have been carried on by
the Division of Agricultural Engineering, Bureau of Public Roads, in co-
operation with the Division of Cotton Insects of the Bureau of Entomology.
