| 摘 要： | 测定了7种杀虫剂对柑桔害虫的天敌——食螨瓢虫、草间小黑蛛和日本方头甲的毒力。结果表明:水胺硫磷对3种天敌毒力均大,氧化乐果对食螨瓢虫,pp321对草间小黑蛛和食螨瓢虫,松脂合剂对草间小黑蛛戊酸醚脂对食螨瓢虫的毒性均大;杀虫脒和胶体硫对3种天敌毒性相对较低。防治柑桔害虫时,应注意保护天敌,慎重选用药剂。

| Abstract: | Experments on the toxicity of seven kinds of insecticides to three natural enemies of citrus insects, Stethorus sp., Cybocephalus nipponicus and Erigonidium graminicolum were made in Southwest Agricultural Uni- versity, Chongqing, during 1987. The results showed that the insecticides had strong toxicity to natural enemies. Samithion was fully toxicant to all of the above three natural enemies. Omethoate was toxicant to Stet- horus sp., pp321 was toxicant to E. graminicolum and Stethorus sp., Resin wash was toxicant to E. graminicolum and Fenvalerate, was toxicant Stet- horus sp. However, Chlorodimeforn and Colloid sulphur had low toxicity to all of the above three natural enemies. |
