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

Nt-mber 110 June, 1923

FRUIT INSECT INVESTIGATIONS
A. L. Quaintance, Entomologist in Charge

Dr. D. T. Fullaway of Hawaii has been appointed specialist in para-
sites of white grubs and has sailed for Yokohama, Japan, where he will be
associated with C. P. Clausen in the Bureau's search for parasites of the
Japanese beetle. Dr. J. F. Illingworth also is now in Japan for the
purpose of searching for parasites of this beetle.

0. I. Snapp, in charge of peach insect investigations at Fort Valley,
Ga., reports that specimens of Conotrachehis amglyptieiis Say and C. cribricollis Say
are being taken occasionally when jarring for the plum curculio, C. nenuphar
Hsrbst. C. anaglypticus breeds in peach, and the life cycle is very similar to
that of C. nenuphar.

Adults of the first generation of the plum curculio started to emerge
June 7. They were leaving the soil in numbers during the 10 days following,
as indicated by an increase of over 100 per cent in the number collected
during that time by jarring. On account of the lateness of the peach crop
this year, it is believed that the Hileys as well as the Georgia Belles and
Elbertas will be attacked by second-generation larvae.

Parasites of Conotrachelus nenuphar are in evidence this year. Chief among
these are Triaspis curoulionU Fitch. Some boxes containing larvae of C. nenuphar
show T. curculionis parasitism as high as 14 per cent.

Fred E. Brooks, of the French Creek, W. Va., station, was in Washing-
ton during the week of June 10 for a conference regarding control of nut
weevils in the Department's experimental chestnut orchards at Bell, Md. He
also visited nut-tree nurseries and orchards in Dinwiddie County, Va., where
there has been a serious outbreak of the hickory twig-girdler , Oncideres cingulata
Say.

Dr. E. D. Ball, accompanied by Dr. A. L. Quaintance, recently visited
the boll weevil statibn at Florence, S. C., being conducted by the Bureau
of Entomology in cooperation with Clemson College. A visit was also made
to the extensive plant-breeding farms of David R. Coker at Hartsville, S. C.

SOUTHERN FIELD-CROP INSECT INVESTIGATIONS
J. L. Webb, Entomologist Acting in Charge

Doctor Hunter spent a few days in Washington during the month conferring

with the Federal Horticultural Board* and attending to various Bureau matters,
including the airplane dusting experiments in Louisiana.

R. C, Gaines, of the boll weevil force, accompanied Doctor Hunter to
Washington to confer with the ste,tist icians of the Bureau of Agricultural
Economics who are cooperating with the Boll Weevil Laboratory in working
up statistics relating to the boll weevil and its depredations.

E. C, Bishopp, in charge of the Dallas, Tex., Laboratory, recently
made a trip to Middieto^m, N, Y, , in connection with ox-warble investigations.
He was in l^ashington June 29 and 30 conferexices with several Department
officials.

Temporary employes have been added to the field force as follov/s:

THUCK-CROP INSECT INVESTIGATIONS
J. E, Graf, Entomologist Acting in Cliarge

David E, Fink, Riverton, N, J. , visited Washington en route to Norfolk,

Va, , whore he investigated the value of ladybirds in controlling various
apbids affecting tiuck crops in that region. This work was undertaken to
check up results obtained from the introduction of ladybirds by the Bureau
of Entomology in I912-I914, Mr, Fink reports that ladybirds were found
abundantly in all fields.

S, G. Smyth reports from Guatemala that he has not yet found any
specimens of the Mexican bean beetle, although a few adults of Enilachna
borealis Fab. have been noted on cucurbits in the field. He states tbiat
throughout a large part of northern Guatemala beans are blooming, so that
it may be reasonably ejcpected that E. corrirpta Muls, will soon be in evidence.
According to Bxologia Centralia-Americana, this species was collected both
at Guatemala City and at Duenas in Guatemala. Mr, Smyth is especially interested
in an effort to obtain parasites of the eggs and pupae of this insect.

C. H , Popenoe is engaged at Sligo, Md, , in a study of chemotropism,
with especial attention to the discovery of attractants or repellents for the

1

more important track-crop insects. Preliminary investigations will cover tests
with synthetic aromatic chemicals in the hope that compounds of immediate use
in practical insect control may he determined.

H, L, Weatheroy, for a number of summers connected v;ith Txuck—Crop
Insect Investigations as special field assistant, has received temporary
appointment to assist h, P. Hov;ard in experiments against the Mexican bean
beetle at Birmingham, Ala.

Guy Fletcher has been temporarily appointed junior entomologist
to assist C, E, Smith at Baton Rouge, La., in 'Truck-Crop Insect Investigations,

Tif, V, Reed, I. J, Condit, and G. E. Riley, for a number of years
connected with this Bureau as collaborators, are now engaged in commercial
y/ork,

b'. Vif, Porter, agent, engaged in eradication of the sv/eet— potato
weevil in Mississippi in cooperation with the State Plant Board, has resigned.

BEE CULTURE DPTESTIGJ'iTIOES

E, F, Phillips, Apiculturist in Charge

The Maryland State Beekeepers* Association will hold their regular
midsummer meeting at the Bee Culture Laboratory, Somerset, Md, , on Saturday
afternoon, July 28, All who e,re interested are invited to attend.

FOREST INSECT INVESTIGATIONS
T, E, Snyder, Entomologist Acting in Charge

Beginning July 1, Dr. A, D, Hopkins, Forest Entomologist in Charge
since Ju.ly 1, 1902, is to devote all of his time to research in connection
with bioclimatics.

Dr, P. C. Craighead, formerly engaged in Forest Insect Investigations,
who has been doing forest insect work in Canada, is to assume duties as
Forest Entom^ologist in Charge in September or October of this year.

On July 1, S. A. Rohwer was transferred from the Forest Insect
Investigations to the miscellaneous fund for duty in the U. . S, National Museum,

In response to a request from, the National Park Service, J, C, Evenden
left the Forest Insect Field Station at Coeur d'Alene, Idaho, June 6, to
ma.ke an examination of serious defoliation apparently caused by the spruce

"budv/orra in the vicinity of the Tower Jails and Camp Roosevelt section,
Yellowstone National Park. On his return Mr, Evenden will make an examination
of a Dendroctonus control project near Boise, Idaho, which is being conducted
by means of logging, and also an area defoliated by the white pine butterfly.
The Dendroctonus control project on the Helena National Forest was completed
May 26, Approximately 5OO trees y/ere treated.

MISCELLANEOUS

(Items from the National Museum contributed by S, A, Rohwer)

U* S. Fisher has practically completed a manuscript dealing v;ith
the West Indian beetles of the family Buprestidae, In connection with his
studies on the species of this family Mr, Fisher has had an opportunity to
examine not only the material in the National Collection but also material
from the British Museum of Natural History, the l\/tuseum of Comparative Zoology,,
the American Museum of Natural History, the Carnegie Museum, and the Poey
Collection in the Philadelphia Academy of Sciences, Besides this he has had
an opportunity to study material from the collections of private workers, and
many thanks are due to some of these, especially Professor Uickham and Pjrof .

S, C, Bruner, for the generous donations they have made to the National
Collection,

Mr, Heinrich has visited the collections of the American Museum,

New York, to study the Kearfott types of microlepidoptera, and also the
collections at the academy of Natural Sciences, Philadelphia, to study the
Clemens types,

Mr, Rohwer spent a few days comparing specimens in the collections in
the American Museum of Natural History, New York, and in the Philadelphia
Academy of Natural Sciences,

On June 22 Miss Isabel Cooper, scientific assistant of the Williams
Galapagos Expedition, brought to Washington for identification the Heterocera
and Hymenoptera secured by this expedition. It is understood that the
types of all the new species are to be retained for the National Collection.
These collections will be studied by Mr, Schaus and Mr. Rohwer,

At the same time Miss Cooper took away several thousand Lepidoptera
which had been secured by William Beebe while v;orking at the British
Guiana Experiment Station, These specimens had been identified by Mr, Schaus
and are being returned to the New York Zoological Society for their collections.
The work at the British Guiana Experiment Station and also the work done by
the Vifilliams Galapagos Expedition is carried on under the direction of
William Beebe, with headquarters '.-at the New York Zoological Gardens.
