Abstract
A total of 165,810 gypsy moth larvae and pupae were collected over two field seasons, using five techniques. Three tachinid species Compsilura concinnata (Meigen), Blepharipa scutellata (Robineau-Desvoidy), and Parasetigena agilis (Robineau-Desvoidy) accounted for 77.1% of the parasites recovered; and B. scutellata comprised 50.4%. Two techniques-burlap-band/tree-species and burlap-band—yielded significantly greater numbers of certain parasites than the general technique. The 1972 and 1973 average percentage of parasitism (12 and 14% respectively) indicated that parasites by themselves, as an individual mortality factor, did not remove a significant proportion of the host population and could not function to limit the rate of increase of the gypsy moth in these areas.This publication has 1 reference indexed in Scilit:
