大棚茄子烟粉虱田间防治药剂的筛选

Screening of Pesticides on Controlling Bemisia tabaci(Gennadius) on Eggplant in Greenhouse

为筛选出防治茄子烟粉虱的高效安全化学药剂,于2014年在南昌市对大棚茄子烟粉虱成虫进行了5种药剂的防控效果比较试验。试验结果表明,20%啶虫脒可溶性粉剂1 000倍液、70%啶虫脒水分散粒剂1 000倍液、1.65%阿维·高氯可湿性粉剂500倍液、10.5%阿维·哒螨灵水乳剂1 000倍液对烟粉虱有较好的防效,最高防效分别为78.45%、77.56%、63.25%、60.23%,可交替使用。

In order to screen out safe and efficient pesticides to control Bemisia tabaci （Gennadius） on eggplant, we conducted a field test of five pesticides, and compared their control efficiences agaist B. tabaci （Gennadius） on greenhouse eggplants in Nanchang at 2014. The results showed that, the four pesticides 20% acetamiprid soluble powder 1 000 times liquid, 70% acetamiprid water dispersible granule 1 000 times liquid, 1.65% avermectin·cypermethrin wettable powder 500 times liquid and 10.5% avermectin·pyridaben water emulsion 1 000 times liquid, had better effects on controlling B. tabaci （Gennadius）, with the highest control efficiencies of 78.45%, 77.56%, 63.25%and 60.23%respectively, so they could be used alternately.
