Abstract

Fall armyworm larvae, Spodoptera frugiperda (J. E. Smith), were collected from volunteer corn at Homestead, FL from April through August and from Bermudagrass, Cynondon dactylon (L.), and paragrass, Brachiarie mutica (L.), in August and September at Belle Glade, FL. Chelonus insularis Cresson, Temelucha sp., and Apanteles marginiventris (Cresson) parasitized 44, 11, and 5% of all larvae collected, respectively. The principal parasite in volunteer corn was C. insularis and A. marginiventris was primarily found in Bermudagrass. Larvae collected from corn were the most frequently attacked with 78 and 72% of the 3rd and 4th instars parasitized, respectively. Larval abundance and parasitization rates in corn were greatest during the months of June and July.
