Özet
The present study was conducted to determine adult emergence period and changes in population density of the pest Lyristes plebejus (Scopoli) in cherry orchards in Izmir province between 2005 and 2008. Studies to determine adult population density were conducted in each of 3 orchards where population changes were monitored in Kemalpaşa county by placing wooden cases 160x25x10 cm in size covering an area of 0.4 m2 with 7 wells covered with mosquito net under ten trees. In these cases, adult emergence under projection of petal of the tree was directly monitored by checking once every week. In the same orchard, ten trees were marked before the first adult emergence and last-stage nymph skin of the emerged adults were counted and removed after checking sub-petals, bodies and branches of the marked trees one to two times in a week. Thus, information was obtained indirectly on adult density. At the end of the present study, it was found that the most emergence of the adults of Lyristes plebejus in Izmir province was at late June and early July and that the adults were observed until early August. It was also determined that adult density varied annually and from one garden to another.
