| 摘 要： | 通过室内和田间罩网试验,测试了吡虫啉、吡蚜酮和矿物油3种低毒药剂对大豆蚜的防治效果及其天敌瓢虫的安全性。研究结果表明,3种药剂对大豆蚜的速杀效果都很好,但是吡虫啉的2种选用浓度对瓢虫表现出一定的有害性,而吡蚜酮和矿物油所用浓度对瓢虫均无明显危害。根据3种药剂对大豆蚜的防效和瓢虫的安全性,吡蚜酮和矿物油的选择毒性最好,推荐需在天敌瓢虫多的季节或配合人工释放天敌瓢虫联合使用。

| Abstract: | The effect of 3 kinds of low-toxicity insecticides to Aphis glycines,and its security to ladybug,were tested under laboratory and field cage conditions.The results showed that Imidaclopridv,Pymetrozine and Paraffin wax all had excellent effect on Aphis glycines.Two different concentration of Pymetrozine and Paraffin wax almost showed harmless to ladybug,but two concentration of Imidaclopridv were all harmful to ladybug to some extent.Based on the security and toxicity of 3 insecticides to ladybug and Aphis glycines,Pymetrozine and Paraffin wax are the best insecticides to be used,especially when ladybugs are abundant in the fields or cooperating with releasing ladybugs artificially. |
