ALFRED C. MORGAN 
A. C. Morgan, Entomologist, in charge of tobacco insect investi- 
gations, with headquarters at Clarksville, Tenn., died at his home in 
Clarksville, July 28. Mr. Morgan graduated from Cornell University in 
i904, and entered the Bureau of Entomology the same year, being asso— 
ciated with the. division known then as the Southern Field Crop Insect 
Investigations. Soon after entering the Bureau he was assigned to in- 
vestigations of tobacco insects and worked in this capacity up to the 
time of his death. 
Through the death of Mr. Morgan the Bureau has lost one of its 
most valuable workers. He was recognized as an outstanding authority 
on tobacco pests and was also a specialist on Thysanoptera. His con-— 
tributions to entomological literature consist mainly of economic pa-— 
pers on tobacco pests. He has, however, described several new genera and 
species of thrips. 
DECIDUOUS-FRUIT INSECTS 
During the present season 106 colonies of Macrocentrus ancyli- 
vora Rohwer, having an average of about 400 adults each, have been reared 
at the Moorestown, N. J., laboratory and distributed in the principal 
peach—growing areas east of the Mississippi River. The parasites have 
been shipped to their liberation points in iced containers with a re- 
markably small loss through mortality in transit. 
At the request of Dr. Paul Marchal, of the French Ministry of Agri- 
culture, three shipments of Macrocentrus ancylivora, the important orient— 
al fruit moth parasite of the Eastern States, have been prepared at the 
Moorestown, N. J., laboratory and shipped to southern France. They have 
been received by G. J. Haeussler, of the oriental fruit moth parasite 
sublaboratory at Nice, and M. Balachowsky, of the French Ministry of Ag— 
riculture. The first two shipments arrived in good condition and nun- 
bers of adults have emerged in France. 
H. G. Butler, in charge of the oriental fruit moth investigations 
at Harriman, Tenn., states that the number of moths taken in traps at 
the Harriman orchard was considerably less than that anticipated from 
the records of 1930. This may be due to a year of fewer insects, a sea— 
son slightly later than that of 1930, or the fact that the larger number 
of traps results in a lower catch per trap. The last factor, however, 
would not be sufficient to explain the difference between the anticipated 
and the actual catches.
