摘　　要：中国梨木虱是目前梨树生产中主要的防治对象,鉴于夏型梨木虱虫态多且世代重叠严重,而冬型梨木虱虫态单一,针对性强,且防治时期在果树休眠期,对寄主植物更安全。本试验以冬型梨木虱为靶标,研究了6种药剂对其的室内触杀效果。45%毒死蜱效果最好致死中时为4.57 d,30%石硫·矿物油效果次之,致死中时为8.714 d,99%矿物油也有效果,致死中时为9.588 d。30%石硫·矿物油和99%矿物油为矿物源农药,对环境友好,不易产生抗性,适合用于防治推广。At present winter-type pear psylla is the main control object in pear production.In view of the variety number of summer paylla and the serious overlapping of generations,and the singleness and pertinence of winter-type pear psylla,and the control period is in the dormant period of the fruit tree,safer for the host plant.The contact killing effect of 6 insecticides on psylla was studied in this experiment.The result showed that 45%Chlorpyrifos had the best lethal effect in 4.57 days,followed by 30%Sulfur mineral oil,8.714 days in the lethal period,99%Mineral oil also had the best lethal effect in 9.588 days in the lethal period.30%Sulfur mineral oil and 99%Mineral oil were mineral pesticide,which were friendly to environment and not easy to produce resistance.
