Abstract
Gypsy moth larvae and pupae (91,902) were collected in 1st cycle populations along the leading edge of the infestation in Pa. from 1974–1977. More than 14,600 parasites were recovered. Parasite associations with pre-culminating, culminating, and post-culminating host populations are given. B. pratensis was recovered most frequently during the pre-culmination phase, B. intermedia during the culmination phase and P. silvestris during the post-culmination phase. Relatively low rates of parasitism were observed in the pre-culmination and culmination phases. Much higher rates were detected in the post-culmination phase. Parasite effectiveness is discussed.This publication has 3 references indexed in Scilit:
