EVALUATION OF INSECTICIDES FOR CONTROL OF STORED-PRODUCT PESTS IN TRANSPORT VEHICLES1
Thirty-three insecticides were evaluated over a 6 year period for their effectiveness against three species of stored-product insects: the confused flour beetle, Tribolium confusum Jacquelin duVal; the black carpet beetle, Attagenus unicolor (Brahm); and a warehouse beetle, Trogoderma glabrum (Herbst). The tests were conducted in transport trailer vans or sea-going cargo containers. The insecticides were formulated for application as aerosols or dusts or both. Dusts generally caused greater mortality than aerosols. Pyrethroids were more effective than other classes of insecticides tested. Cyfluthrin and S-cyano-(3-phenoxyphenyl)- methyl (1 R-cis-3-(l,2-dibromo-2,2-dichloroethyl)-2,2-dimethylcyclopropanecarboxylate were the most promising pyrethroids. The most effective organophosphate aerosol was O-(3- chloro-l-methyl-1H/-pyrazol-5-yl) O-ethyl O-methyl phosphorothioate. Generally, carbamates had very limited toxicity, as did other miscellaneous insecticides.
