Abstract:Male pickleworm pupae were exposed to substerilizing gamma radiation (10, 15, 20, or 30 krads) and moths mated to untreated virgin females. Survival of F1, progeny was decreased, especially by higher doses, and at most doses developmental time was prolonged. The percentage of F2 egg hatch showed that sterility was greater in the untreated F1, males than in the irradiated P1 males and that 20 krad produced sterility in these F1 offspring. Inbred F1 pairs were more affected than outbred F1 males. Exposure of pickleworm larvae to 32°C for 8 days or longer and pupae for 2 days or longer drastically reduced egg hatch, but had little effect on larval survival and adult emergence or mating. Reciprocal crosses of untreated moths and moths that were treated for 3 days at 32°C as pupae showed that sterility persisted when treated males were outbred to untreated females.
