常用杀虫剂对新入侵害虫螺旋粉虱的田间药效试验

摘要/Abstract

摘要： 螺旋粉虱是新入侵中国海南的危性害虫，为迅速压低虫口密度，进而将其逐步扑灭，开展了螺旋粉虱的药剂防治研究；选用2.5%敌杀死乳油、20%吡虫啉可溶性液剂、480g/L乐斯本乳油、1.8%阿维菌素乳油、2.5%功夫水乳剂、20%啶虫脒可溶性液剂等常用杀虫剂，进行了田间药效试验；结果表明：药后1~10d，2.5%敌杀死乳油的防效在94.09%~100%之间，2.5%功夫水乳剂的防效在91.72%~100%之间，20%吡虫啉可溶性液剂的防效在32.24%~70.96%之间，1.8%阿维菌素乳油的防效在-11.54%~21.54%之间；因此，2.5%敌杀死乳油和2.5%功夫水乳剂是防治时可供选用的良好药剂，20%吡虫啉可溶性液剂和1.8%阿维菌素乳油对螺旋粉虱的速效性和持效性均较差，不适用于螺旋粉虱的防治。

Abstract: Aleurodicus disperses Russell was a new dangerous invasive insect of Hainan province. The action of pesticides against Aleurodicus disperses Russell was studied in order to depress and eradicate the population. The six normal pesticides of 2.5% deltamethrin EC, 20% imidacloprid SL , 480g/L chlorpyrifos EC, 1.8% abamectin EC, 2.5% lambda-cyhalothrin SE and 20% acetamiprid SL were selected and their efficiency was compared by field trial. The result showed: the effect of 2.5% deltamethrin EC and 2.5% lambda-cyhalothrin SE were the 94.09%~100% and 91.72%~100% respectively during 1 to 10 days after treatment while the effect of 20% imidacloprid SL and 1.8% abamectin EC were 32.24%~70.96% and -11.54%~21.54% respectively. 2.5% deltamethrin EC and 2.5% lambda-cyhalothrin SE were the effective pesticides against Aleurodicus disperses Russell with the quicker and more persistent action while 20% imidacloprid SL and 1.8% abamectin EC were unsuitable for using because of lower action.
