Regulation of adult diapause inCoccinella septempunctata septempunctata andC. septempunctata brucki from two regions of Japan (A Minireview)

In similar climatic conditions of central/northern Europe and Hokkaido, Japan, both subspecies ofCoccinella septempunctata L. have similar life-cycles: long-day photoperiodic response ensures the induction of winter diapause. In the mild climate of Honshu, Japan,C. s. brucki Mulsant shows a different life cycle: short-day photoperiodic response leads to the induction of summer diapause while overwintering is quiescence. All populations show an important variation in photoperiodic response.
