MOVEMENT OF ANGOUMOIS GRAIN MOTH (LEPIDOPTERA, GELECHIIDAE) IN A SMALL-FARM ECOSYSTEM

The purpose of this study was to monitor activity and movement of Ango umois grain moth, Sitotroga cerealella (Olivier), in a small-farm ecos ystem. Moth activity was determined using sticky traps placed in bin v ents of storage bins containing shelled corn and pheromone traps place d in concentric circles across the farm with the bins at the center. M oth activity was concentrated in and around the grain bins fr om June to August and at cent plots in September and October. Mark-recapture s tudies confirmed moth dispersal from the bins to corn plots during Jul y-September. Knowledge of the spatial dynamics of Angoumois grain moth may contribute to pest management programs.
