Abstract:

Blattella germanica (L.) males succumbed to two consecutive sublethal doses of hydramethylnon (an amidinohydrazone) spaced up to 6 days apart. The same effect was not observed with a carbamate (propoxur) or organophosphate (chlorpyrifos) insecticide. Radiotracer analysis revealed presence of 14C residues inside cockroaches for at least 21 days following topical application with 14C-labeled hydramethylnon. A direct relationship between temperature and hydramethylnon toxicity was observed. Cockroaches unaffected by hydramethylnon at 16°C died when temperature was increased to 28°C 3 days later, but moribund individuals recovered when temperature was lowered from 28 to 16°C for 10 or more days.
