We determined nonlethal physiological effects of hydroprene on the German cockroach, Blattella germanica L., and the effects of hydroprene exposure on German cockroach susceptibility to traditional insecticides. Live and dry weights of German cockroach adults exposed as nymphs to the juvenile hormone analog hydroprene increased significantly (6-35%) in both sexes. The change in weight was affected by hydroprene dose and time after adult emergence. Hydroprene treatment did not affect total body lipids and carbohydrates consistently. However, total body urates of males and females increased significantly. The susceptible and multiresistant German cockroach strains were significantly more susceptible to propoxur at the lower hydroprene application rate (0.697 mg per tub) than the untreated cockroaches. Hydroprene application also significantly lowered the LD•• for chlorpyrifos of the multiresistant strain at the lower hydroprene application rate. However, hydroprene failed to affect chlorpyrifos susceptibility of the susceptible strain.
