New contributions to the Turkish aphid fauna and species composition (Hemiptera: Aphididomorpha) in Isparta forests

A study was conducted on the aphid fauna of Pinus nigra Arnold. subsp. pallasiana (Lamb.) Holmboe., Pinus brutia Ten., Cedrus libani A. Rich., Abies cilicica (Antoine & Kotschy) Carrière (Pinaceae), Juniperus spp. (Cupressaceae), Quercus spp. (Fagaceae) and Robinia pseudoacacia L. (Leguminosae) forests in Isparta Province between 2018 and 2020. Using systematic and random sampling, 9,252 specimens in 68 species from the families Aphididae and Phylloxeridae (14 species at genus level only) were identified between 2018 and 2020. It was determined that Appendiseta robiniae (Gillette, 1907) collected from R. pseudoacacia is a Nearctic species, which was identified as a new record for the aphid fauna of Türkiye. Fifty-five species were detected in 2019, and a further 51 in 2020 using systematic sampling. The species with the highest number of specimens in 2019 were Myzocallis boerneri Stroyan, 1957 (16.0%), Eulachnus rileyi (Williams, 1911) (12.3%) and Cinara cedri Mimeur, 1936 (10.4%). In 2020, the species with the highest number of specimens were E. rileyi (10.1%), A. robiniae (9.3%) and Cinara orientalis (Takahashi, 1924) (7.2%). The highest number of aphid species was collected from P. nigra in the three years (2018-2020). The second highest numbers were collected from Quercus coccifera L. in 2018 and 2020, and P. brutia in 2019.
