Dermaptera species in fruit orchards in the Western Black Sea region of Turkey

Abstract :

Earwigs are sub-social species, with their females defending their eggs and young nymphs. They are omnivores feeding on decayed animal or plant waste, aphids, and other small insects. In the study, 345 earwig samples were collected from apple (48%), cherry (40%) and hazelnut (12%) trees from June/July to November in 2015 and 2016. The aphids were found as the most abundant insect in the apple orchards in June, but most red mites in cherry orchards were observed in July and August. Three species, Forficula auricularia Linnaeus, Forficula smyrnensis Serville, and Guanchia hincksi (Burr), were collected from the apple and cherry orchards in Bolu province; and F. auricularia, G. hincki, and Apterygida albipennis (Megerle von Mühlfeld) were collected from the hazelnut orchards in Düzce province. F. smyrnensis was recorded for the first time in Bolu and G. hincksi in Düzce. F. auricularia was the common species in the fruit areas of the Western Black Sea Region. This paper also discusses information on the seasonal occurrence and feeding behavior of earwigs.
