摘　　要：[目的]明确9种生物杀虫剂桶混迈丝对苹果绣线菊蚜的田间防治效果及对苹果树的影响。[方法]采用常规喷雾法进行试验。[结果]10%吡虫啉可湿性粉剂、20%啶虫脒可溶粉剂、1.8%阿维菌素乳油、6%鱼藤精微乳剂桶混迈丝对苹果绣线菊蚜防效高,速效性好,药后1、7 d的防治效果分别达92.02%~96.22%和96.97%~99.61%;0.3%印楝素乳油、0.5%藜芦碱可溶液剂、1.3%苦参碱水剂桶混迈丝防效高,速效性较好,药后1、7 d的防治效果分别为83.05%~87.93%和96.94%~99.85%;25%噻虫嗪水分散粒剂桶混迈丝防效较高,速效性较好,药后1、7 d的防治效果均在84%左右;1.5%天然除虫菊素水乳剂桶混迈丝防效差,药后1、7 d的防治效果分别为23.97%和-90.65%。桶混迈丝可显著提高10%吡虫啉可湿性粉剂的速效性,药后1 d防治效果由未桶混迈丝的59.45%提高至94.62%。药后1 d至苹果成熟期,各药剂处理对苹果生长发育均无明显影响。[结论]筛选出的生物杀虫剂在试验剂量下桶混迈丝喷雾对苹果绣线菊蚜防效理想,对苹果安全,可大面积推广。[Objective]To determine the field control effect of 9 kinds of biological insecticides mixed with Maisi against Aphis citricola and its influence on apple trees.[Method]Field efficacy was measured by using foliar spraying method.[Result]Imidacloprid 10%WP,acetamiprid 20%SP,abamectin 1.8%EC,rotenone 6%ME barrel mixed with Maisi had high control and quick-acting effect.Efficacy reached 92.02%-96.22%and 96.97%-99.61%on 1 and 7 d after treatment,respectively.The control effect of azadirachtin 0.3%EC,veratrine 0.5%SL and matrine 1.3%AS mixed with Maisi were 83.05%-87.93%and 96.94%-99.85%on 1 and 7 d after treatment,respectively.The control effect of thiamethoxam^(2)5%WG mixed with Maisi was about 84%at 1 and 7 d after treatment.The pyrethrin 1.5%EW mixed with Masi had poor control effect,which were 23.97%and-90.65%at 1 and 7 d after application.Barrel mixed Masi could improve the quick-acting effect of imidacloprid 10%WP significantly,and the control effect was increased from 59.45%to 94.62%after 1 d application.There was no significant effect on the growth and development of apple from 1 d after treatment to the mature stage of apple.[Conclusion]The screened bio insecticides mixed with Masi at the tested dose were ideal for control of Aphis citricola,which was safe and could be popularized in large scale.
