Popis:	Normal and irradiated laboratory-reared Heliothis zea (Boddie) moths were released in screened field cages and in fields of tobacco and cotton. The nocturnal activities and incidence of mating of laboratory-reared and wild moths were observed. Laboratory-reared moths irradiated with 10 krad and released in field cages were competitive with nonirradiated laboratory-reared moths. The competitiveness of irradiated moths was not altered by the time interval (5 and 30 h) between irradiation and release, the mating status of the male, or by the time interval (24 and 48 h) between mating and release. Normal and irradiated, laboratory-reared males released in the field in either the presence or absence of laboratory-reared females were not significantly different in their nocturnal behavior and mating competitiveness. The interaction of wild and laboratory-reared moths was largely limited to wild males mating with laboratory-reared females.
