The German cockroach, Blattella germanica (L.) is an important indoor public health insect pest in the urban environment. Frequent usage and over-reliance on insecticides have led to the development of insecticide resistance in this species. Little is known on the impact of locomotory and grooming behavior of the intoxicated German cockroaches after insecticide bait exposure. Baits containing the following active ingredients were chosen and evaluated against susceptible (UCR) and resistant strains (SY and Ryan-strain): 0.05% abamectin, 1% clothianidin, 0.05% fipronil, 1% isocycloseram, and 2% hydramethylon. The effects of the insecticides on the above-said behaviors are discussed.
