“…Several excellent discussions of diapause have been presented and the reader is referred to these for a more complete consideration of diapause in insects (Andrewartha, 1952;Lees, 1955;decide, 1962;Danilevskii, 1965;Beck, 1968;Mansingh, 1971)• Diapause has been characterized as an endocrine deficiency syndrome (deWilde, 1962) -which in adults is manifested by physiological changes such as lack of reproductive development and reduced respiratory rates (Lees, 1956;Slama, 1964;Calabrese and Stoffolano, 1974b). In addition behavioral changes may occur in mating activity (Blondheim and Broza, 1970;Zdarek, 1970) and flight activity (Nuorteva, 1966;Bro-wn, et al, 1974). Accompanying these various behavioral changes associated with diapause is the observation that many insects show changes in their feeding behavior.…”
