Susceptibility of Blattella germanica male adults to 61 commercial insecticides was evaluated by diet dipping method. Among them three insecticides of dichlorvos, fenitrothion, and fipronil showed over 90% mortality. The insect was more susceptible to dichlorvos and fenitrothion in filter paper contact method than in diet dipping one, but fipronil was vice versa. Toxicities of the three chemicals were evaluated by application parts of the such as head, thorax, abdomen, and legs. Dichlorvos and fenitrothion were more toxic when applied to head, and flpronil was thorax.
