Female cabbage loopers, Trichoplusia ni, were crossed with males irradiated with 20 krad of gamma irradiation. Eggs were collected, flxed, and stained for microscopic examination after females showed no sign of embryonic development. Thus, a major cause of nonhatching eggs may be failure to fertilize. Eggs that were fertilized with irradiated sperm showed slower early embryonic development that those which were fertilized by untreated sperm. No chromosomal abnormalities were apparent, and virtually all embryos developed into well-formed larvae that failed to hatch. The absence of early acting lethals may be characteristic of radiation studies with lepidopteran males. (auth)
