Thirty-three species of parasites were reared from four species of lepidopterous larvae. Larvae collected from insect resistant and susceptible soybeans showed no differences in insect parasitism. Hosts and parasitism levels for 1976 and 1977 respectively were: green cloverworm,Plathypena scabra(F.), 11.2 and 8.5%; corn earworm,Heliothis zea(Boddie), 1.2 and 5.7%; soybean looper,Pseudoplusia includensWalker, 9.7 and 16.0%; and velvetbean caterpillar,Anticarsia gemmatalisHubner, 0.4 and 1.9%. The most prevalent parasite reared fromP. scabra,H. zeaandP. includenswasApanteles marginiventris(Cresson).P. includenswas a new host record forA. marginiventris.Meteorus autographae(Vier.) was the most prevalent parasite ofA. gemmatalis.P. scabrawas the only host exhibiting lower population levels in the insect resistant ED73-37l than in the susceptible soybean variety ‘Bragg’.
