Abstract

Heliothis spp. larvae were parasitized by Microplites croceipes (Cresson) to varying degrees throughout the study. Parasitism was not significantly greater in larvae collected from the Okra leaf cotton (open canopy), but Spicaria rileyi (Farlow) Charles infection was significantly greater in larvae collected from Delta Pine cotton (closed canopy). A decline in parasitism throughout the study was observed.
