摘　　要：梨喀木虱1年发生6～7代,以成虫在树干裂缝、杂草、落叶中越冬,对早酥梨为害最严重;已发现天敌有多种蜘蛛及5目8科13种昆虫,在自然状态下天敌对梨喀木虱控制作用明显;不科学的化学防治是造成梨喀木虱危害加重的主要原因;用1 0%爱诺虫清3000倍液、20%梨虱霸乳油2000倍液、5%蚜虱净乳油1500倍液防治梨喀木虱效果都在95%以上,1 0%爱诺虫清是生物药剂,更宜推广。Cacopsylia chinensis occur 6～7 generation in each year and live through the winter by imago in crack of tree stem, weeds and fallenleaves, it severely damaged pear (Zhaosu) At present, its natural enemies such as various kinds of spiders and insects of 5 orders, 8 families, 13 speciesUnder natural conditions the control effect of natural enemies on Cacopsylla chinensis is obvious; nonscientific chemical control measures are main reasons caused serious damages of Cacopsylla chinensis The control effects of 10% with concentration of 3 000, 20% Lishiba with concentration of 2 000, 5% Imidacloprid with concentration 1 500 on Cacopsylla chinensis are all over 95% And the 10% Avermectins is easy popularization because it is a kind of biological medicament
