REGULATION OF ADULT DIAPAUSE IN COCCINELLA-SEPTEMPUNCTATA SEPTEMPUNCTATA AND C-SEPTEMPUNCTATA BRUCKI FROM 2 REGIONS OF JAPAN (A MINIREVIEW)

In similar climatic conditions of central/northern Europe and Hokkaido , Japan, both subspecies of Coccinella 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 M ulsant shows a different life cycle: short-day photoperiodic response leads to the induction of summer diapause while overwintering is quies cence. All populations show an important variation in photoperiodic re sponse.
