不同杀虫剂对小麦蚜虫的防效研究

文章通过8种药剂对麦蚜的防效试验,并进行了方差分析,筛选出防治麦蚜的最佳药剂,结果表明：6%吡阿合剂乳油、10%吡虫啉乳油、3%啶虫脒乳油的速效性好;10%吡虫啉乳油、3%啶虫脒乳油、0.9%阿维菌素、6%吡阿合剂乳油、5%高效氯氰菊酯乳油、7.5%莫吡乳油的持效性好;6%吡阿合剂乳油、10%吡虫啉乳油、0.9%阿维菌素的长效性好。综合评价,6%吡阿合剂乳油、10%吡虫啉乳油的防效最好,其速效性防效在98%以上,持效性防效在98%以上,长效性防效在50%以上,3%啶虫脒乳油、20%苦皮藤乳油、5%高效氯氰菊酯乳油、0.9%阿维菌素和7.5%莫吡乳油处于中间水平,以上药剂的防效均高于对照药剂氧化乐果。

Control Effect of Different Pesticides on Wheat Aphid

The efficacy of eight kinds of insecticides were evaluated against aphids in wheat field,and carried on the variance analysis,it screened the best insecticides against the aphids in wheat field.The results showed that 6%IA EC、10%imidacloprid EC and 3%acetamiprid EC had quickly available,10%imidacloprid EC、3%acetamiprid EC、0.9%abamectin EC、6%IA EC、5% betacypermethrin EC and 7.5%AcI EC had high lasting available.6%IA EC、10%imidacloprid EC and 0.9%abamectin EC had long effect.Overall evaluation,6%IA EC and 10% ,imidacloprid EC had high control efficiency. Their quickly available is over 98%, lasting available is over 98% ,long effect is over 50% ;3% acetamiprid EC,20% celastrus angulatus EC,5% betacypermethrin EC,0.9%abamectin EC and 7.5%Aci EC belonged to the medium level, the controlling efficiency of the above insecticides is higher than the contrast. This paper will provide a scientific basis in agricultural production against wheat aphids.
