在田间进行了0.9%阿维.印楝素乳油对豇豆上美洲斑潜蝇的防治效果及对美洲斑潜蝇寄生蜂的影响试验。结果表明,0.9%阿维.印楝素乳油1200、1500倍液和对照药1.8%阿维菌素乳油3000倍液、0.3%印楝素乳油300倍液药后3、7、10d对美洲斑潜蝇的防治效果均在90%以上。3种农药对美洲斑潜蝇寄生蜂复合种群各有不同程度的影响,0.9%阿维.印楝素乳油1500倍液、1.8%阿维菌素乳油3000倍液、0.3%印楝素乳油300倍液药后10d调查,其寄生率分别为4.6%、13.1%、3.9%,分别只达到对照寄生率的17.9%、51.0%、15.2%。
In the field 0.9% Avi Azadirachtin EC on cowpea on the control effect of the United States Liriomyza sativae and parasitic wasps on the impact of the test. The results showed that 0.9% Avia azadirachtin 1200, 1500 times and control 1.8% abamectin EC 3000 times, 0.3% azadirachtin EC 300 times after treatment 3, The control effect of the flies in more than 90%. The three kinds of pesticides had different degrees of impact on the complex population of parasitoids of the American leafminer, Apia, 0.9% Avicel Azadirachtin 1500 times, 1.8% Abamectin 3000 times, 0.3% Azadirachtin EC 300 Parasitization rates were 4.6%, 13.1% and 3.9%, respectively, after 10 days of drug administration, reaching only 17.9%, 51.0% and 15.2% of the control parasitism rates respectively.
