Abstract

Oaks [Quercus spp. (Fagaceae)] are an important forest tree species on worldwide, and oak is generally the dominant species in most of the Mediterranean forests. Also, this genus is one of the most important forest trees in Turkey in terms of species richness and distribution area with about a quarter of the country’s forest area. Aphids in the family Aphididae from order Hemiptera are represented more than 5000 species belong to 510 accepted genera, and about half of them feed on different tree species in all or part of their life. Approximately 225 aphid species belongs to more than 40 genera associated with oak trees worldwide. With the study, the aphid species feed on oak trees aimed to determine in the South Marmara Region of Turkey including Çanakkale and Balıkesir Province. Aphid sampling was done between March and October from 2018 to 2020. As a result of the identification of the collected aphid samples, eight species from five genera belong to three subfamilies (Calaphidinae, Lachninae and Thelaxinae) of the family Aphididae were revealed. These oak aphids are Hoplocallis picta (Ferrari, 1872); Myzocallis (Myzocallis) boerneri Stroyan, 1957; Myzocallis (Pasekia) komareki (Pašek, 1953); Tuberculatus (Tuberculoides) eggleri Börner, 1950; Tuberculatus (Tuberculoides) maximus Hille Ris Lambers, 1974; Tuberculatus (Tuberculoides) moerickei Hille Ris Lambers, 1974; Lachnus roboris (Linnaeus, 1758) and Thelaxes suberi (Del Guercio, 1911). The obtained results show that oak trees in the South Marmara Region have a rich diversity of aphids. Also in this study, the presence and distribution of aphid species identified on oak trees in the studies conducted in Turkey were evaluated to reveal the diversity of the oak aphids in Turkey.
