اولین گزارش Cacopsylla (Hepatopsylla) zetterstedti (Thomson, 1877) (Hemiptera: Psyllidae) از ایران

Jumping plant-lice or psyllids are plant sap sucking insects with about 4000 described species in the world. They are considered into as economically important pests in agriculture and forestry as vectors of serious plant diseases and as potential control organisms of exotic invasive plants. The psyllid fauna of the Middle East is poorly known, and Iran is no exception in this respect. During a faunistic survey of the jumping plant-lice in the Tehran province of Iran in spring and summer 2023, Cacopsylla (Hepatopsylla) zetterstedti (Thomson, 1877) was collected on Sea-buckthorn, Hippophae rhamnoides (Elaeagnaceae). This is the first record of the species from Iran. The examined specimens are deposited in the Department of Biodiversity, Institute of Science and High Technology and Environmental Sciences, Graduate University of Advanced Technology, Kerman, Iran. Hippophae rhamnoides, is a deciduous, dioecious shrub native to the temperate regions of Asia and Europe. Thirty-two psyllid species have been hitherto reported from H. rhamnoides. These species belong to the families Psyllidae (24 spp.) and Triozidae (8 spp.). The newly reported species is morphologically similar to but distinct from Cacopsylla nasuta (Horváth). Cacopsylla zetterstedti and the related C. nasuta, which was previously reported from Iran, are common on their host and usually occur together on the same plant. Cacopsylla zetterstedti has been reported from Central and Northern Europe, Turkey, Georgia and Tadzhikistan. With the new record from Iran, its known distributional range in Asia is considerably expanded.
