oa Journal of the Entomological Society of Southern Africa - Susceptibility of Locustana pardalina (Walker) to nine insecticides by topical application



The object was to find an insecticide to replace BHC for control of L. pardalina. Gamma-BHC and eight other insecticides were applied topically to adults and hoppers. DDVP, cidial, S2957 and naled were more toxic and faster-acting than BHC. The acute toxicities of diazinon and fenitrothion were similar to that of gamma-BHC, but both acted faster than BHC. Carbaryl and mercaptothion were less toxic than BHC but had the same speed of action.
