Updated feeding preferences of Leiopus Audinet-Serville species in Turkey with new host plants for endemic longicorn beetle Leiopus syriacus abieticola Sama & Rapuzzi (Coleoptera: Cerambycidae: Lamiinae)

Abstract :

Host plant associations are given and updated for all species-group taxa of Leiopus Audinet-Serville (Cerambycidae: Lamiinae) in Turkey. We have found two new host plants for the longicorn beetle Leiopus syriacus abieticola Sama & Rapuzzi, 2010 in South Turkey in the city Kahramanmaraş. The adults emerged from stems of the herbs Viscum album abietis and Viscum album austriacum (Loranthaceae) where larvae were found. The diet of Leiopus syriacus abieticola is broader than previously thought and a larger diversity of host plants can probably enable them to occur in more diverse habitats. On this occasion, all Turkish species-group taxa of Leiopus Audinet-Serville are firstly reviewed and evaluated with their body length, adult period, host plants, provincial and regional distribution in Turkey, and the range in the world. Consequently, the members of Turkish Leiopus Audinet-Serville on the base of feeding preferences are determined for 13 deciduous plant families and one coniferous plant family. The most preferred host plant families of them are reported as Fagaceae, Juglandaceae, Moraceae and Rosaceae respectively. On the other side, Viscum album L. as host plant has been reported only four longicorn beetle taxa with newly recorded Leiopus syriacus abieticola Sama & Rapuzzi among the cerambycid taxa known all over the world up to now. Accordingly, these taxa which are distributed in Turkey each, are proposed as possible biological control agents for a semi-parasitic herb Viscum album L., which causes damage to forests and fruit trees of economic importance in Turkey and in the world. In addition, provincial and regional distribution patterns in Turkey are given onto a mapping figure for each taxon with the present new records. Moreover, an identification key for the taxa of Leiopus Audinet-Serville in Turkey is also provided.
