Özet
The present study aimed to explore oviposition preference and larval survival of Lobesia botrana Den. & Schiff. (Lepidoptera: Tortricidae), which is a key pest of vineyards. The study was carried out using natural population of the pest on cultivars of Yalova incisi, Flame Seedless, Sultana and Crimson Seedless in 2009 and 2010. The effect of the cultivars on the preference by the pest was evaluated according to number of laid-egg and larvae with weekly counting intervals from flowering to harvest. As a result of the study, grape cultivars impacted on egg-laying preference of females with larval survival indicating naturally parallel tendency. The most and the least cultivars preferred by the pest were Yalova Incisi (6.4 eggs, 3.7 larvae) and Flame Seedless (2.0 eggs, 1.1 larvae), respectively. After Yalova incisi, the most preferred cultivars in terms of egg-laying and larvae feeding were Crimson Seedless (4.4 eggs, 2.6 larvae). Therefore, one tried to find out if different cultivars could have any effects with the conclusion that L. botrana had to be kept under control by environmentally friendly IPM programs. Studies have been conducted on development of alternative control methods for the pest which is rather difficult to chemically control. Of all alternative methods, growth of cultivars preferred less by the pest plays an important role.
