DECIDUOUS-FRUIT INSECTS 
A. L. Quaintance, in Charge 
On August 26 Dr. Herbert Osborn, of Ohio State University, and 
Dr. F. W. Poos, in charge of investigations of forage-crop insects at 
Arlington, Va., made a brief visit to the field laboratory at Vincennes, 
Ind., and later to that at Bentonville, Ark. 
John Gray has been appointed Entomologist, pending certification, 
and assigned to the study of the ecology of the oriental fruit moth, 
with headquarters at Moorestown, N. J. Dr. Gray was formerly Professor 
of Entomology and Plant Pathology at the University of Florida, and has 
recently received a doctor's degree from Cornell University. 
Dr. H. W. Allen and Dr. John Gray recently visited the Dominion 
Parasite Laboratory at Belleville, Ontario. 
B. E. Montgomery, J. T. Creighton, R. C. Newton, Earl Lott, A. J. 
Warren, and Stanley Slater have been appointed temporary Field Assistants 
and assigned to the work on the oriental fruit moth. 
Approximately 35,000 adults of the parasite Macrocentrus ancyli-— 
vora have been reared and distributed from the oriental fruit moth field 
laboratory at Moorestown, N. J., in this season. They were liberated 
in 70 colonies in important peach-growing centers east of the Missis- 
sippi River in which this parasite had not previously been found. In 
this program, and in supplementary projects undertaken by the Canadian 
government and by several States, this laboratory has worked in close 
cooperation with a number of others. The entomological services of 
those States have cooperated actively in the work of distribution and 
recovery. Several States have undertaken mass rearing of this valuable 
parasite from parasitized material collected in New Jersey. To meet 
the demand, an additional 400,000 parasitized larvae have been collected 
and shipped from this center under the supervision of this laboratory. 
Numerous recoveries have been made and the results to date seem very 
promising. 
G. J. Haeussler, who is investigating parasites of the oriental 
fruit moth, with headquarters at Antibes, France, reports that several 
parasites of this insect are present in southern Europe, but are rela— 
tively lacking in abundance. He has begun mass rearing of a species of 
Pristomerus for shipment to the United States. 
Contributions from the Japanese-Beetle Laboratory 
On August 5 E. J. Hoddy, Agricultural Agent for the Louisville & 
Nashville R. R., visited the Japanese-Beetle Laboratory to confer with 
Dr. W. &. Fleming and J. W. Lipp concerning carbon-disulphide emulsions 
used in the control of larvae of the Japanese beetle and their possible 
use in the control of root aphids.
