Aphid species (Hemiptera: Aphidoidea) and their natural enemies on forest trees in Isparta province

The study was carried out to aim aphid fauna in Anatolian black pine [Pinus nigra Arnold. subsp. pallasiana (Lamb.) Holmboe.], brutian pine (Pinus brutia Ten.), Taurus cedar (Cedrus libani A. Rich.), Taurus fir [Abies cilicica (Ant. & Kotschy) Carr.], juniper (Juniperus spp.), oak (Quercus spp.) and black locust (Robinia pseudoacacia L.) forests in Isparta province in 2018-2021. As a result of systematic and random sampling, 9 252 individuals belonging to 69 species (14 of them were at genus level) were collected in 2018-2020. It has been determined that Appendiseta robiniae (Gillette, 1907) is a new record for the aphid fauna of Turkey. Although the fifty-six species were detected in 2019, fifty-six species were detected in 2020 with systematic sampling. The species with the highest number of individuals were Myzocallis boerneri (16.04%), Cinara cedri (10.42%) and Eulachnus tauricus (9.51%) in 2019. In 2020, the species with the highest number of individuals were Appendiseta robiniae (9.27%), Cinara orientalis (7.21%) and Aphis craccivora (6.49%). The highest number of aphid species was detected in Pinus nigra in all three (2018-2020) years. The highest species number was found in Quercus coccifera in 2018 and 2020, and Pinus brutia in 2019 after P. nigra. In the study, 38 natural enemy species were determined from the Coleoptera (21), Neuroptera (6), Raphidioptera (1), Diptera (1), Hemiptera (5) and Hymenoptera (5) in 2019-2020. Species with the highest number of natural enemies in 2019; Oenopia lyncea (19.0%), Harmonia quadripunctata (11.3%) and Adalia decempunctata (7.7%). In 2020, the species with the highest number of individuals were Harmonia quadripunctata (16.3%), Coccinula quatuordecimguttata (14.3%) and Hippodamia (Hippodamia) variegata (10.2%). The number of natural enemies was highest in Pinus nigra (15 species) and Cedrus libani (13 species).
