Abstract
A survey of gall-inducing aphids on elm and poplar trees was carried out during 2017 in Razavi Khorasan province, NE Iran. As a result, 15 species of gall-inducing aphids from 5 genera, all belonging to the subfamily Eriosomatinae, were recorded on 6 host plant species. The collected species included the genera Eriosoma, Kaltenbachiella, Pemphigus, Tetraneura and Thecabius. Pemphigus passeki Börner (Hemiptera: Aphididae) and Pemphigus populinigrae (Schrank) (Hemiptera: Aphididae) on Populus nigra var. italica (Salicaceae) were new records for the Iranian aphid fauna. Both new recorded species belong to the tribe Pem-phigini, subfamily Eriosomatinae. Among the identified species, 8 aphid species were new records for Razavi Khorasan province.
