摘要
比较测定了6种杀虫剂对烟粉虱的毒力以及田间药效。毒力试验研究结果表明：6种药剂对烟粉虱成虫的毒力排序为：70%艾美乐水分散粒剂〉5%氟虫氰悬浮剂〉25%阿克泰水分散粒剂〉5%啶虫脒可溶性粉剂〉10%吡虫啉粉剂〉5%云菊乳剂,6种药剂对烟粉虱成虫均有一定的杀灭作用,70%艾美乐水分散粒剂0.000 184 mg/L对烟粉虱的成虫表现有最高毒力;6种药剂对烟粉虱3-4龄若虫的毒力排序分别为：25%阿克泰水分散粒剂〉70%艾美乐水分散粒剂〉5%啶虫脒可溶性粉剂〉5%氟虫氰悬浮剂〉10%吡虫啉粉剂〉5%云菊乳剂,阿克泰对烟粉虱的3-4龄若虫有最高毒力。总体来看,70%艾美乐水分散粒剂无论是对烟粉虱成虫还是3-4龄若虫均具有较高毒力。田间药剂试验结果表明：70%艾美乐水分散粒剂、10%吡虫啉粉剂、5%氟虫氰悬浮剂在施药后第1天的时候效果最好,均超过80%;5%云菊乳剂的持效期最长。
The toxic experiment results showed that the toxicity order of 6 pesticides to the adults of B. tabaci was;The comparative experiment of the toxicites to Bemisia tabaci and field trial of 6 insecticides were carried out,the experiment result demonstrated that the sequence of the toxicites of 6 presticite after test to Bemisia tabaci were as follows, admire〉 fipronil〉 actara〉 acetamiprid〉 imidacloprid〉 pyrethrins. These six insecticide all had some effects on killing the adults of B. tabaci,admire shows the highest toxicity. The toxicity orders of 6 pesticides to 3〉4 instar nymphs of B. tabaci were actara〉admire〉acetamiprid〉 fipronil〉imidacloprid〉 pyrethrin and actara shows the best toxicity. In a few words, admire shows higher toxicity both to adults and to instar nymphs. The field trial show the controlling effects of admire,imidacloprid,fipronil is the best and over 80% ,the endurance of pyrethrins is the longest.
