Stored-product insects associated with eight feed mills in the midwestern United States
Journal of Economic Entomology 101 (3), 998-1005
Abstract: Commercial food- and pheromone-baited pitfall traps and pheromone-baited sticky traps were used during 2003 to survey stored-product insect adults in eight participating feed mills in the midwestern United States. Across the eight feed mills, 27 species of beetles (Coleoptera) and three species of moths (Lepidoptera) were captured in commercial traps. The red flour beetle, Tribolium castaneum (Herbst), was the most abundant insect species captured inside the eight mills. The warehouse beetle, Trogoderma variabile (Ballion), was the most abundant insect species outside the mill and in the mill load-out area. The Indianmeal moth, Plodia interpunctella (Hübner), was the most abundant moth species inside the mill and in the mill receiving area. The Simpson's index of species diversity among mills ranged from 0.39 (low diversity) to 0.81 (high diversity). The types of species found among mills were different, as indicated by a Morisita's index of <0.7, for the majority of mills. The differences in the types and numbers of insect species captured inside, outside, in receiving, and in load-out areas could be related to differences in the types of animal feeds produced and the degree of sanitation and pest management practiced.
