Technical Abstract: Aerosol insecticides can be important components of insect management plans for mills, food warehouses, and processing plants. In the United States, synergized pyrethrin insecticide is used alone or combined with an insect growth regulator (IGR) insecticide, either methoprene or hydroprene. The presence of food material can result in increased survival of adult red or confused flour beetles exposed to synergized pyrethrins, but larvae appear to be more susceptible than adults. Results of field trials with the IGRs methoprene and pyriproxyfen indicate residual persistence of IGRs. The red flour beetle is more susceptible than the confused flour beetle to IGRs, but combination of pyrethrin with the IGR may produce an additive effect on the confused flour beetle. These results will help mill and warehouse managers optimize use of aerosol insecticides for insect control.
