Abstract/Contents:"During 1920's and early 1930's USDA entomologists imported Tiphia vernalis Rohwer from Korea and Tiphia popilliavora Rohwer. (Hymenoptera Tiphiidae) from Japan for Japanese beetle control. Numerous wasp releases were made throughout the northeastern U.S. Releases of T. vernalis were made between 1936 and 1949 in six of Connecticut's eight counties and T. popilliavora was released in 5 counties between 1921-1940. The primary target of these releases was the Japanese beetle. However, T. vernalis and T. popilliavora are parasitoids of the Oriental beetle as well. These parasitoids feed on the larvae with T. vernalis attacking the 3rd instars during spring and T. popilliavora attacking 2nd or 3rd instars during late summer. The objectives of this study were: 1) to determine the parasitism rates of T. vernalis on Japanese and Oriental beetle larvae; and 2) to determine if T. popilliavora wasps were present in the state. Parasitism rates on Japanese beetle larvae reached on average 55% across twelve sites around the state. Parasitism rates on Oriental beetle on average reached 17%. T. vernalis can be a significant source of mortality for the Japanese beetle and it should be integrated with other management tactics. T. popilliavora wasps were found in six counties. The wasp is active during August and it is found until early September. The wasps collected readily oviposited on Japanese or Oriental beetle larvae. The public is generally unaware of these Tiphia wasps and integrated pest management guidelines need to suggest methods to conserve and enhance their populations."
