DOCTORATE CONFERRED UPON MR. E. A. SCHWARZ 
Members of the Bureau of Entomology will be pleased to learn that the 
honorary degree of Doctor of Science was conferred upon Mr. EH. A. Schwarz 
by the University of Maryland at its commencement exercises, June 10. 
Dr. Schwarz’s scientific work in the United States was begun in the 
Museum of Comparative Zoology, Cambridge, Mass., in 1873 and 1874, in the 
days of Agassiz. In 1875 and 1876, he studied Coleoptera for the Detroit, 
Mich., Scientific Association, and in 1878 was employed by Dr. John L. Le 
Conte to investigate the beetles of Colorado. While in Colorado on this 
errand he was offered a position in the Department of Agriculture by Dr. 
C. V. Riley. He accepted the position and has been connected with the 
Division (and Bureau) of Entomology continuously ever since. Dr. Schwarz 
is Honorary Custodian of the Coleoptera in the Division of Insects, U. S. 
National Museum, having been appointed to that position in 1897, after 
the death of the coleopterist, Martin L. Linell, of the Museum staff. 
FRUIT INSECT INVESTIGATIONS 
A. L. Quaintance, Entomologist in Charge 
Oliver I. Snapp, in charge of the peach insect work for the 
Bureau of Entomology at the Federal and State laboratory at Fort 
Valley, Ga., reports a large amount of thorough spraying and dust- 
ing for the control of the plum curculio in Georgia. The protection 
from attack by this insect of varieties of peaches thus far harvested 
has been most excellent. 
The varieties of peaches grown and the ripening periods have 
an important bearing on the amount of damage sustained by the 
second generation of the curculio. Thus the Hiley, a very important 
commercial sort, matures as a rule just ahead of egg laying by the 
second brood, whereas the Georgia Belle and Elberta varieties, 
ripening later, are oviposited in very freely. Daily jarring records 
during 1922 show a remarkable decrease in numerical abundance of the 
curculio as compared with conditions during 1921, amounting to a very 
important reduction since 1920. Numerous factors are doubtless con- 
cerned in this general reduction of the insect in numbers in the 
Georgia peach belt, but it is believed that one of the most important 
influences has bsen the careful attention given by orchardists to 
remedial work recommended.
