为了探讨阿维菌素·噻嗪酮悬浮剂对柑桔粉虱的防治效果,2014年在广西桂林柑桔春梢老熟期(柑桔粉虱幼虫盛发期)设置15%阿维菌素·噻嗪酮悬浮剂1 000倍液等6种药剂处理,进行田间防治试验。结果表明,15%阿维菌素·噻嗪酮悬浮剂对柑桔粉虱1~2龄幼虫有较好的防治效果,2 000、1 500、1 000倍液药后15d的防治效果分别为72.5%、81.3%和85.9%;对照药剂1.8%阿维菌素乳油3 000倍液、25%噻嗪酮可湿性粉剂1 500倍液、3%莫比朗乳油3 000倍液的防治效果分别为89.5%、81.8%和80.5%。 In order to investigate the control effect of abamectin and buprofezin on citrus whiteflies, 15% avermectin was applied in the ripening stage of citrus green shoots (citrus whitefly larvae) in Guilin, Guangxi in 2014, · Buprofezin 1000 times suspension and other six kinds of agents treatment, field control trials. The results showed that 15% avermectin / buprofezin SC had better control effects on 1st and 2nd instar larvae of Citrus whitefly, and the control effects at 15d after 2 000,1 500 and 1 000 times were 72.5%, 81.3% and 85.9% respectively. The control efficacy of control agent 1.8% avermectin EC 3000, 25% buprofezin 1500 mg and ECM 3000% 89.5%, 81.8% and 80.5%.
