When adult Popilla japonica Newman were allowed to feed on soybean foliage sprayed with 25 candidate insecticides applied at 3 rates (4-, 8-, and 16-ounces active ingredient per 100 gallons of water), acephate caused greater mortality than the standard, carbaryl, when the residues were subjected to either very heavy or light rainfall. Also, Shell SD-9098 (O-[2-chloro-1-(2, 5-dichlorophenyl) vinyl] (O,O-diethyl phosphorothioate) caused greater mortality than carbaryl after a heavy rainfall and was about equally effective when conditions were drier; Imidan® (O,O-dimethyl phosphorodithioate S-ester with N-(mercaptomethyl)phthalimide) caused more mortality than carbaryl with relatively dry conditions; and Bay 37289 (O-ethyl O-(2,4,5-trichlorophenyl) ethylphosphonothioate), trichlorfon, Pennwalt TD-5032 (hexamethylditin), and phosalone caused more mortality than carbaryl after a heavy rainfall but were inferior at drier conditions.
