中文摘要: |
为了明确几种常用杀虫剂对捕食性天敌(异色瓢虫Harmonia axyridis Pallas、东亚小花蝽Orius sauteri Poppius、智利小植绥螨Phytoseiulus persimilis)和寄生性天敌(松毛虫赤眼蜂Trichogramma dendrolimi Matsumura、丽蚜小蜂Encarsia formosa Gahan、中红侧沟茧蜂Microplitis mediator Haliday)的影响,在室内采用标准生物测定方法测定了阿维菌素、吡虫啉和噻嗪酮对以上昆虫天敌的毒力。结果表明:三种杀虫剂对六种供试天敌的毒力大小表现出相似趋势,即阿维菌素 > 吡虫啉 > 噻嗪酮;三种药剂对寄生性天敌的毒力均显著高于捕食性天敌。因此在害虫综合治理中应尽量选用对天敌昆虫相对安全的昆虫生长调节剂类的噻嗪酮,以起到保护天敌的作用。 |

In order to clarify the effect of common insecticides to predatory enemies (Harmonia axyridis Pallas, Orius sauteri Poppius, Phytoseiulus persimilis)and parasitoids (Trichogramma dendrolimi Matsumura, Encarsia formosa Gahan, Microplitis mediator Haliday), the standard bioassay were determined the toxicity of abamectin, imidacloprid and buprofezin to these natural enemy Our results demonstrated that the toxicity of tested insecticide to these natural enemy have the same trend that is abamectin > imidacloprid > buprofezin In addition, the toxicities of these insecticides on parasitoids were significant higher than on the predator Furthermore, the relative safety insecticide buprofezin was recommended to control insect in integrated pest management programme |
