JAPANESE BEETLE INVESTIGATIONS 
Loren B. Smith, in Charge 
Dr. F. W. Pettey, senior entomologist of the Department of Agricul-— 
ture of South Africa, visited the Japanese beetle laboratory on June ll. 
Herbert Osborn, Jr., formerly of the Hawaiian Sugar Planters' Ex— 
periment Station, visited the Japanese beetle laboratory on June 17 ae 
study methods of shipping and handling parasites. 
D. M. Daniels, of the Geneva, N. Y., Agricultural Experiment Sta— 
tion, recently spent two weeks at the Japanese beetle laboratory in an 
endeavor to transfer parasites of the oriental peach moth from New Jer— 
sey to New York. 
At the present time five species of Oriental parasites of the Jap— 
anese beetie are established in New Jersey, there being two species of 
Tiphia and one each of Centeter, Dexia, and Prosena. Tiphia vernalis 
was recently recovered for the first time from a colony that was estab— 
lished two years ago. The same species has been recovered from three 
colonies established last year. Dexiaventralis has been recovered, in. 
both this year and last year, from the first colony established. Twenty— 
three thousand Tiphia cocoons have been received this year from India, 
and a shipment of 3,000 adult Tiphia vernalis from Japan arrived in good 
conditicn, with 42 per cent alive. Five thousand Prosena sibirita were 
received from Japan on parasitized grubs. 
The miscible carbon disulphide developed in 1927 has given excel— 
lent results under varied commercial conditions during the spring of 1928. 
C. H. Hadley reported at Riverton, N. J., June 15. Upon the sepa— 
ration; July 1, of the quarantine and research phases of the Japanese 
beetle project, Mr. Hadley will assume direction of the quarantine work.

laboratories. 
Allison Lee, of Earlham College, Richmond, Ind., is assisting for
