Excerpt from the report: In the search for more effective, safer, and less costly insecticides for protecting food, feed, seed, and other agricultural commodities against insect infestation, the Stored-Product Insects Research Branch of the Agricultural Research Service conducts a program of basic evaluation of insecticides to compare the effectiveness of new compounds against representative species of stored-product insects. Sixty-eight candidate insecticides were evaluated for direct-contact, residue, and vapor toxicity to red flour beetle adults, Tribolium castaneum (Herbst), and black carpet beetle larvae, Attagemis megatoma (F.).
