Parasites Attacking Fall Armyworm Larvae, Spodoptera Frugiperda, in Late Planted Field Corn
Abstract
Parasites emerged from larvae of the fall armyworm, Spodoptera frugiperda (J. E. Smith), collected from (1) under the husks of corn ears, (2) exposed surface areas of corn plants, and (3) broadleaf signalgrass, Brachiaria platyphylla (Griseb.) Nash. Mortality was highest among larvae collected from the signalgrass and lowest among those gathered from the surface areas of the corn plants. Eight species of parasites, representing the Braconidae, Eulophidae, Ichneumonidae, and Tachinidae were collected. Chelonus texanus Cresson caused the highest mortality followed by Meteorus autographae Muesebeck and Euplectrus platyhypenae Howard.Downloads
