MONTHLY LETTER OF THE BUREAU OF ENTOMOLO 
UNITED STATES DEPAKTMENT GF AGRICULTU 





DECIDUOUS-FRUIT INSECT INVESTIGATIONS 
A. L. Quaintance, in Charge 
The Bureau of Entomology is beginning this season an intensive study 
Of the parasites of the codling moth. At the outset the work will consist 
Chiefly of a survey of the principal apple regions of the United States, 
to bring up to date and amplify our information regarding the identity, 
distribution, and relative abundance of the various parasites affecting the 
' codling moth. Some 20 entomologists in various parts of the country, in-— 
cluding many of the field men of this division, have agreed to cooperate 
and send in, for rearing, material collected in their respective sections. 
Luther Brown has been assigned to the project, which is centered at the 
field laboratory at Silver Spring, Md. 
On May 28 Dr. B. A. Porter attended a conference with entomologists 
of Virginia, Maryland, and West Virginia, at Charles Town, W. Va., to ob— 
Serve an outbreak of the pistol case bearer, and to discuss methods of con-— 
trol. While this insect is normally of very minor importance, a few or-— 
Chards in the Shenandoah Valley have developed serious infestations. One 
orchard in particular has suffered a defoliation averaging fully 50 per 
cent, in addition to considerable direct injury to the fruit. 
A. W. Morrill, Jr., a graduate of the University of California, has 
been appointed Field Assistant and assigned to duty at Yakima, Wash.. where 
he is assisting E. J. Newcomer in apple-insect investigations. 
W. P. Yetter, Jr., a graduate of the Colorado Agricultural College, 
was appointed Associate Entomologist May 9, and assigned to duty at Vincen— 
nes, ind., where he will carry on investigations of the oriental peach moth. 
R. S. Filmer, Junior Entomologist, who was associated with Dr. Camp— 
bell in orchard-insecticide investigations, resigned from the Bureau, effec— 
tive May 2, to accept a fellowship at Rutgers University. 
The botanical expedition of West Virginia University, made up of 25 
students under the direction of Dr. P. D. Strausbaugh, head of the botani- 
cal department of that University, visited the field laboratory at French 
Creek, W. Va., June 19.
