Özet:

About 5100 aphid (Hemiptera: Aphidoidea) species that feed on different host plants have spread all over the world. About 5000 aphid taxon feed on different plant species. Aphids are small, soft-bodied and one of the sap-feeding insect groups and also can damage almost all plants. Some aphid species are specific to only one host plant, while some feed on numerous host plants. In this study, aphid fauna and host plants of aphids were deter-mined in Büyükada islands of İstanbul was determined in this study. Aphid species were distributed from cultivat-ed plants, wild trees and shrubs in the area. During these study, 150 aphid samples were collected in the area. Apterae and alatae individuals of aphid samples were collected as much as possible from aphid colonies on culti-vated and ornamental plants. 43 aphid taxa including two new records Turkey aphid fauna (1 family, 6 subfami-lya, 6 tribus ve 23 genus) were determined on 46 different plant species at the end of the study. Malva neglecta, Nerium oleander, and Pinus spp. are the most sampled plant species. Aphis craccivora, Aphis fabae, and A. spiracola are the most determined aphid species in the area. All defined aphid species are the first records for the Büyükada island. Findings of the presented study and other recent studies showed that with the detailed studies, Turkey aphid fauna will be substantially increased thanks to the more detailed local studies.
