Abstract
INDUCTION of diapause, at 65° F., in the European corn borer, Ostrinia nubilalis (Hbn.), requires that last-instar larvæ be exposed to photoperiods of 9.5 to 14 hr. of light a day for about 3 weeks; initiation of diapause is then marked by cessation of feeding, a sharp reduction in oxygen consumption, and failure to pupate when placed in an environment favouring completion of development1,2. Our interest in the physiology of diapause prompted a search for other changes associated with its induction. This communication reports differences in the amino-acid composition of diapause and non-diapause borers.
