摘　　要：为了探究4种常用杀虫剂对芒果蓟马的防效,本研究在百色田阳芒果基地开展不同杀虫剂防治芒果嫩梢蓟马的田间试验。结果表明20%多杀·甲维盐SC 30 g a.i.·hm^(-2)在药后7 d内的防效均在78%以上,防效最佳,其次是6%乙基多杀菌素SC 9 g a.i.·hm^(-2)在药后7 d内的防效在71%以上,20%吡虫啉SLX和25%吡虫·异丙威WP两种浓度处理的防效均在60%以下。因此在芒果蓟马防治上建议将20%多杀·甲维盐和6%乙基多杀菌素与其他杀虫剂轮换使用,同时加强区域统一防治,以提高防效。In order to explore the field control effects of four commonly used insecticides on mango thrips,field trial of different insecticides in the control of mango thrips was carried out in the mango base of Tianyang,Baise.The results showed that,within 7 days after application,the control effect of 20%carbendazim-methyl emamectin benzoate SC 30 g ai·hm^(-2 ) was above 78%,that of 6%spinetoram SC 9 g ai·hm^(-2) was above 71%,and that of 20%imidacloprid SLX and 25%imidacloprid·isoprocarb WP were both below 60%.Therefore,in the control of mango thrips,it is recommended that 20%carbendazim-methyl emamectin benzoate and 6%spinetoram should be used in rotation with other insecticides,while strengthening the unified regional control to improve the control effect.
