Abstract
In a previous investigation on the effects of sublethal doses of fenitrothion (O,O-dimethyl-O-(3-methyl-4-nitrophenyl)phosphorothioateo)n the tobacco hornworm,Manduca sexta(L.), it was found that the treated larvae developed asynchronously, required more time to reach the pupal stage, and had larger bodyweights than the control larvae (Stewart and Philogène 1983). Regressive moults, faster pupal development, and shorter longevity of the adults were also observed. The impact of sublethal doses of insecticides on subsequent generations of insects has, however, received limited attention. We now present experimental evidence that the progeny of treated insects can also show some of the characteristics described above, an observation that may have significant consequences in the field.Keywords
