Collection of Fall Armyworm (Lepidoptera: Noctuidae) Using Selected Pheromone Lures and Trap Designs

Abstract

Two trap designs and three sources of commercially-produced pheromone lures were used to capture fall armyworm, Spodoptera frugiperda (J. E. Smith), males in silage corn and peanuts in north-central Florida. Unitraps baited with Trécé and Scenturion lures captured more moths than Scentry-baited traps. Gas chromatographic detection of the pheromone blend suggested no differences in acetate component ratios among lures. Unitraps collected more moths than Heliothis cone traps. Behavioral observations at night showed that equal percentages of moths were initially collected in both traps but that moths were able to escape from cone traps.
