Aphidophagous coccinellid and parasitoid species determined in the Çanakkale Province with a new record for the parasitoid fauna of Turkey

Abstract

This study was conducted between 2013 - 2015 to determine aphidophagous coccinellid and parasitoid species of aphids, their diversity and tritrophic associations (parasitoid/predator-host aphid-host plant) in the Çanakkale Province. In the course of the investigations, 10 species belonging to six genera of the subfamily Aphidiinae (Hymenoptera: Braconidae) were determined, in addition to 12 species belonging to 10 genera of the family Coccinellidae (Coleoptera). Among the parasitoids, Aphidius hortensis Marshall, 1896 is a new record for the Turkish parasitoid fauna. Lysiphlebus testaceipes (Cresson, 1880) (32.9%) and Lysiphlebus fabarum (Marshall, 1896) (23.0%) were more extensively found compared to other parasitoid species. Similarly, Coccinella septempunctata Linnaeus, 1758 (35.1%) and Adalia bipunctata (Linnaeus, 1758) (22.8%) were recorded as the most common predator species. Aphis fabae Scopoli 1763 had the greatest diversity among the parasitoids (Shannon-Wiener H = 0.658), while Cinara pini (Linnaeus, 1758) had the greatest diversity among the predators (Shannon-Wiener H = 1.386). As for tritrophic associations, 18 parasitoid-aphid associations on 14 host plants and 28 predator-aphid associations on 19 host plants were determined. The A. hortensis - Liosomaphis berberidis (Kaltenbach, 1843) association on Berberis sp. (Berberidaceae) is here newly recorded from Turkey. With the present study, the aphidophagous coccinellid and parasitoid species are determined for the first time in the Çanakkale Province of Turkey.
