Adult male pink bollworms, Pectinophora gossypiella (Saunders) 2 to 3 days old, were irradiated with 13 or 6.5 krads of gamma rays and outcrossed to untreated females. The F/sub 1/ progeny were reared and paired with untreated moths. The effects on mating and sperm transfer by F/sub 1/ males were similar to those obtained in previous studies: F/sub 1/ males mated normally but often failed to inseminate females with eupyrene (nucleate) sperm. Also, 35 percent of the F/sub 1/ females (13 krad) mated with normal males failed to receive (or store) eupyrene sperm in their spermathecae. Histological studies of 8, 24, 48, or 96-h-old eggs deposited by inseminated F/sub 1/ females mated with untreated males or by untreated females mated with F/sub 1/ males showed that most eggs were fertilized and that embryonic development proceeded until a definitive postblastokinesis embryo was formed. For example, untreated females mated with F/sub 1/ males from the 13 krad test had an egg hatch of 15.4 percent, but 86 percent of the eggs had formed a segmented embryo at 48 h and 72 percent had formed a definitive embryo after 96 h of development. Similar trends were found in the eggs produced by F/sub 1/ females mated with untreated males. This suggests that most embryonic development can be completed without some of the genetic information contributed by the male or female gamete.
