Abstract

Aerosol insecticides can be important components of insect management plans for mills, food warehouses, and processing plants. In the United States, synergized pyrethrin is used alone or combined with an insect growth regulator (IGR), either methoprene or hydroprene. The presence of food material can result in increased survival of adult Tribolium castaneum (Herbst) or Tribolium confusum Jacquelin du Val exposed to synergized pyrethrins, but larvae appear to be more susceptible than adults. Results of field trials involving methoprene and pyriproxyfen indicate residual persistence of the IGRs. Tribolium castaneum is more susceptible than T. confusum to IGRs, but combination of pyrethrin with the IGR may produce an additive effect on T. confusum.
