Abstract

Larvae of the common sooty wing, Pholisora catullus, and pupae of the yellow-collared scape moth, Cisseps Fulvicollis, were collected in corn plantings containing different manipulated, indigenous weed communities to determine if these Lepidoptera had parasitoid species in common with the European corn borer, Ostrinia nubilalis. Pholisora catullus larvae were collected from lambsquarter, Chenopodium album, and redroot pigweed, Amaranthus retroflexus, whereas pupae of C. Julvicollis were obtained from corn. Four parasitoid species were reared from P. catulIus: Cotesia pholisorae, Oncophanes americanu (Hymenoptera: Braconidae), Gambrus ultimus, and Sinophorus albipalpus (Hymenoptera: Ichneumonidae). Of these, O. americanus and S. albipalpus represent new host records. Gambrus ultimus, however, was probably parasitizing a primary parasitoid of P. catullus. Itoplectis conquisitor and Vulgichneumon brevicinctor (Hymenoptera: Ichneumonidae) were reared from C. fulvicollis; V. brevicinctor had not previously been associated with this host. Both species reared from C. fulvicollis and Gambrus ultimus have been reported from O. nubilalis.
