摘　　要：试验结果显示,参试药剂对蓟马均有一定防效,施药后1 d 0.3%绿晶印楝素乳油150和225 mL/hm2;赛文1500和2250 mL/hm2;2.5%菜喜悬浮剂900和1500 mL/hm2的防效分别为99.77%和99.75%;84.00%和60.79%;54.28%和56.79%。药后10 d 0.3%绿晶印楝素乳油150和225 mL/hm2的防效分别达到96.06%和96.31%,表明该药对蓟马防治速效性和持效性均较好。The experiment of efficacy of the tested insecticides was conducted to Kill Thrips taba which seriously harmed yield in cotton field. The final results showed that all the tested bio- insecticides had certain control effect. After spraying the insecticides one day the effect of 0.3% Azadimchtin（EC） at dosage of 150 mL and 225 mL per hectare; 0.18% Abamectin. ＋ BT（WP） at dosage of 1500 mL and 2 250 mL per hectare; 2.5% Spinosad at dosage of 900 mL and 1500 mL could reach 99.77%,99.75%;84.00%,60.79%;54.28%,56. 79% respectively.The effect of 0.3%Azadirachtin（EC） at dosage of 150 mL and 225 mL per hectare could reach 96.06% and 96.31% after 10 days of treatment. The conclusion of the experhnent also showed that the 0.3% Azadirachtin（EC） maintained had perfect effect on controlling Thrips tabaci with rapid and sustainable way, compared with other ones.
