摘　　要：采用玻片浸渍法测定了12种药剂对3种捕食螨的毒力。结果表明,在5种杀螨剂中,炔螨特的毒力最低,阿维.哒螨灵的毒力最高;在5种杀虫剂中,噻嗪酮的毒力最低,高效氯氰菊酯的毒力最高;在2种杀菌剂中,代森锰锌的毒力低于咪鲜胺。但同种药剂对不同捕食螨的毒力不同,3种捕食螨对炔螨特的敏感性依次为胡瓜钝绥螨[Amblyseius(Neoseiulus)cucumeris]<巴氏钝绥螨[Amblyseius(N.)barkeri]<尼氏真绥螨(Euseius nicholsi),而对阿维.哒螨灵则为尼氏真绥螨<胡瓜钝绥螨<巴氏钝绥螨。Toxicity of 12 insecticides to 3 predatory mites was tested with slide maceration method. The results showed that among the 5 acaricides, propargite had the lowest toxicity to the predatory mites, but Avi pyridaben presented the highest toxicity. Among 5 insecticides, buprofezin showed the lowest toxicity, while beta-cyper- methrin demonstrated the highest toxicity to the predatory mites. The fungicide mancozeb showed the lower toxic- ity than another fungicide prochloraz. Furthermore, our data presented that the same agent revealed different toxicity on different predatory mites. The sensitivity of 3 predatory mites to propargite ranked from low to high as Amblyseius （ Neoseiulus ） cucumeris 〈 Amblyseius （ N. ） barkeris 〈 Euseius nicholsi . However, the sensitivity to Avi pyridaben ranked from low to high as E. nicholsi 〈A. （N.） cucumeris〈A. （N.） barkeri.
