![]() During the period of winter quiescence, arrest of ovarian development was characterized in most samples by immaturity of the ovaries in all females and, in some samples, by the presence of a few females with signs of vitellogenic resorption. Also, adults were found with enlarged fat bodies, and the median duration of preoviposition period in females transferred to the above laboratory conditions was 90 days in early July and 82 days in early August. The diapause gradually terminated from late August to late October and was followed by a period of quiescence extending from November to March of the following year.ĭuring the summer diapause, arrest of ovarian development was indicated by immaturity of the ovaries in all sampled females and the complete absence of vitellogenic resorption signs. septempunctata females were in diapause during July and August. Measurements of the duration of pre-oviposition period in females taken monthly from the summit of Mount Kitheron in central Greece (1993–1994) and transferred to laboratory conditions of high temperature (25☌), long day (16 hrs light/24 hrs), and presence of aphids, indicated that the C. septempunctata adults migrate to mountainous aestivo-hibernation sites. ![]() In the lowlands, all instars are abundant in spring becoming scarce from July until the end of the warm period of the year they are absent in winter. ![]() Coccinella septempunctata (Coleoptera: Coccinellidae) in Greece is a multivoltine species. ![]()
