Abstract
This study reports seasonal presence of Coccinella septempunctata L. (Coleoptera: Coccinellidae) in Southeast Turkey, in 2008, 2009 and 2010. Samples were collected from crops in agricultural areas at altitudes of 10 m, 800 m and 1400 m from stands of wild herbaceous plants , and at 1750 m from stone debris fields. First C. septempunctata adults were collected at the beginning of June at Tentcamp (800 m) and Tozlu (1400 m), early in July at Sarikiz (1700 m) when the mean air temperature reached 30°C. Adults became active in spring, after aestivating around Sarikiz and overwintering there under snow. First adults emerged on 2nd April in 2009 around Edremit Gulf when mean air temperature reached 14.8°C. Adult and immature stages of C. septempunctata were recorded attacking aphid populations till the end of June. C. septempunctata was present there for only one period each year during which they completed one generation. Adult individuals of this generation returned to Mount Ida to aestivate. Maximum numbers of adults present on Mount Ida in the first week of August in 2009 and 2010 were recorded. C. septempunctata adults aestivate and overwinter at Sarikiz on Mount Ida after completing their development on aphids in April, May and June around Edremit Gulf.
Highlights
Coccinella septempunctata L. 1758 (Coleoptera: Coccinellidae), is one of the most common species of ladybird in the Palearctic (Hodek, 1966) and recently spread to America (Evans, 2004)
In the area around Edremit Gulf C. septempunctata was only recorded from April to June
According to Sarospataki & Marko (1995) the maximum numbers of flying adults of C. septempunctata were recorded at the beginning of May and end of June
Summary
Coccinella septempunctata L. 1758 (Coleoptera: Coccinellidae), is one of the most common species of ladybird in the Palearctic (Hodek, 1966) and recently spread to America (Evans, 2004). 1758 (Coleoptera: Coccinellidae), is one of the most common species of ladybird in the Palearctic (Hodek, 1966) and recently spread to America (Evans, 2004). This species feeds mostly on aphids (Aphididae) (Kuznetsov, 1975; Formusoh & Wilde, 1993). According to Honek (1989) some individuals of C. septempunctata diapause under rocks and weeds when air temperature is high in August, whereas others remain active until October in Central Europe. According to Bodenheimer (1943) and Ricci et al (2005) in areas that experience high temperatures in the Mediterranean region C. septempunctata adults move to higher altitudes in June after spending early spring reproducing. C. septempunctata aggregates in Greece on Mount Kitheron from July, after actively reproducing in April and
