Newly emerged adult Pectinophora gossypiella (Saunders) , when exposed to 25 or more krad of gamma irradiation and allowed to mate with untreated insects of the opposite sex. produced no fertile adult progeny. First and 2nd-filial-generation adults from adults treated with 5-18 krad exhibited varying degrees of sterility. This feature was not so pronounced in the 3rd.filial-generation adults. Irradiation of mated females at 10 to 30 krad gave results similar to those of mating of males and females irradiated at these dosages prior to their mating.
