Effect of kaolin particle film treatment on winterform oviposition of the pear psylla<Emphasis Type="Italic">Cacopsylla pyri</Emphasis>

Laboratory and field experiments were conducted to evaluate the efficacy of kaolin particle film on winterform oviposition of the pear psyllacacopsyllapyri (L.) (Hemiptera: Psyllidae). Kaolin particle film (kpf) treatment significantly reduced winterform oviposition rates in both choice and no-choice tests in the laboratory. In choice tests, overwintered females laid 11 times more eggs on water-treated dormant shoots than on shoots treated with particle film, within 21 days after treatment. In no-choice tests, kpf treatment also significantly reduced egg numbers compared with water-treated controls. The results of field trials carried out in southwestern Turkey (Antalya) during the late winter — early spring of 2004 and 2005 showed very good efficacy of kpf treatment in comparison with water-treated control. Kpf treatment (just before egg laying, during the dormant-postdormant period) delayed egg-laying activity in overwintered females for up to 3 weeks from the beginning of the experiment and continued to suppress oviposition significantly in comparison with watertreated control up to 4 weeks. Our overall results suggest that kpf treatment may be useful in pear psylla management programs by decreasing winterform oviposition, particularly in conjunction with other control tactics.
