| 摘 要： | 应用CT—43双毒乳剂防治小菜蛾,菜青虫和豆荚螟有较好的防治效果。以500倍稀释液防治菜青虫的平均防效为93.9％,防治小菜蛾的平均防效为84.8％,防治豆荚螟的平均防效为83.2％,对棉铃虫的防治效果为86.5％。防治效果受虫龄和气温的影响较大。CT—43双毒乳剂对斜纹夜蛾高龄幼虫防治效果欠佳。

| Abstract: | CT-43 Emulsion was diluted 500 times to control Plutella xylostella, Pieris rapae, Monica testulalis and Heliothis armigera in the field, The correct mortalities are 84.8%, 93.9%, 83.2%and 86.5% respectively. The results against the first or second instar larvae of Prodenia litura are very effective while the effects to 3-5 instar larvae are not satisfactory. |
