AB - AbstractBackcross (BC) progeny resulting from interspecific hybridization ofH. subflexa(Guenee) females ×H. virescens(F.) males and backcrossed toH. virescensmales eight times (BC8) entered physiological diapause, survived the winter, and emerged the following spring at the same time asH. virescens.Heliothis subflexamoths from diapausing pupae also emerged at ca. the same time asH. virescens.Diapausing BC andH. virescenspupae reacted similarly to all treatments with low temperatures in the laboratory. Diapausing BC andH. virescenspupae, in the absence of other factors such as free water, etc., withstood extremely low temperatures in the laboratory for short periods of time.Subsequent Be moth generations were collected after an initial release and also the following spring during the spring emergence period ofH. virescens. When infused into the naturalH. virescenspopulation, BC moths carrying the sterile male trait entered diapause, survived the winter, and emerged the following spring.
