Özet

A willow sawfly, Nematits salicis (Linnaeus, 1758) (Hymenoptera: Tenthredinidae), is a new record for the Turkish fauna and a new pest of willow (Salix spp.) in Turkey. Its developmental stages, biology, damage, and parasitoids were studied in Erzurum during 2002 and 2003. Adults appear during the last three weeks of August, and females insert eggs in groups under the cuticle of the lower surface of willow leaves starting at the leaf apex. Larvae are leaf-edge feeders and consume the entire leaf leaving only the midrib. Nematus salicis is univoltine and overwinters as prepupae in cocoons in the soil. One larval parasitoid was reared, Hyperbatus segmentator (Holmgren) (Hymenoptera: Ichneumonidae), which is new record for Turkey. One species of egg parasitoid, Tetrastichus sp. (Hymenoptera: Eulophidae) also was reared. The percentage of larval parasitism is low, but egg parasitism averages 32.8%.
