Seasonal populations of Spodoptera frugiperda, S. exigua, S. eridania, Heliothis virescens, Helicoverpa zea and Pseudoplusia includens [Chrysodeixis includens] and their parasitoids, were monitored on late-season cotton in north-central Florida in 1992. The cotton was planted as a 2nd crop, following maize, in one field and as a 1st crop in a 2nd field, in which cotton had not been grown for many years. At least 12 species of parasitoids emerged from noctuid larvae collected from cotton plants. The most common parasitoids were Cotesia marginiventris, Meteorus autographae, Cardiochiles nigriceps, Netelia sayi and Copidosoma truncatellum. Cotesia marginiventris had the greatest potential as a biological control agent, as it attacks a broad range of pests including the Heliothis/Helicoverpa complex, Spodoptera spp., and Chrysodeixis includens. none
