摘　　要：为克服梨木虱对单一药剂长期使用产生抗性以及高毒农药对环境的污染,研究阿维菌素与蚜虱净的混配药剂对梨木虱的防治效果。结果表明:阿维菌素与蚜虱净混配防治梨木虱,具有良好的速效性和持效性;药后1 d的防治效果为87.1%,高于各单剂和对照药剂;药后15 d的防治效果为93.2%,显著高于单剂10%吡虫啉WP 1 000倍和对照药剂40%水胺硫磷EC1 000,与1.8%阿维菌素EC 2 000倍差异不显著,但阿维菌素与蚜虱净混配扩大了杀虫谱。To overcome resistance to pesticides of Psylla chinensis because of long-term use of single agents and highly toxic pesticide pollution on environment,the control effect of mixed pesticides from avermectin and imidacloprid on psylla chinensis were studied.The results showed that abamectin mixed with imidacloprid had a good quick effect and lasting effect to control Psylla chinensis.The control effects was 87.1% after 1 d,it was higher than the single-dose and 40% isocarbophos EC 1 000 times;the control effect was more than 90% after 15 d,it was 93,2% remarkably higher than 10% imidacloprid WP 1 000 times and 40% isocarbophos EC 1 000 times,and no remarkable difference with 1.8% Avermectin EC 2 000 times,but the insecticidal spectrum was expanded.
