Notes: [Original title: Sarikamis (Kars)'ta Titrek Kavak (Populus tremula L.)'ta zarar yapan bocek turlerinin tespiti ve bunlardan bazi onemli turlerin biyolojisi uzerinde calismalar.] Eighteen insect pests belonging to different orders and families were determined as pests on aspen (Populus tremula) in Sarikamis (Kars), Turkey during 1996-97. The forests in this region are composed of Scots pine (Pinus sylvestris) mixed with aspen constituting individual native groups. Among the determined species, Chaitophorus tremulae, Chionaspis salicis, Lepidosaphes ulmi, Chrysomela collaris, Crepidodera aurea, Byctiscus betulae and Phyllonorycter apparella were the most important and abundant pests, with a widespread distribution. Poecilonota variolosa, Cerambyx (Mesocerambyx) scopoli, Hylotrupes bajulus, Leptura quadrifasciata [Strangalia quadrifasciata], Rhagium bifasciatum, Saperda (Anacrea) carcharias, S. (Argalia) perforata and Xylotrechus rusticus were rare and had low population densities. Biological characteristics are described.
