摘  要:
在室内采用药膜法测定了几丁质、除虫菊提取液混配对刺槐叶瘿蚊成虫的毒力,据其LC50值及CTC值比较不同配比对毒力的增效作用。结果表明:触杀效果较好的几丁质与除虫菊提取物以1∶3混配,共毒系数为159.82,增效作用明显。

摘  要:
Toxicties of mixtures of chitin and pyrethrum extract onObolodiplosis orhiniaeadults were obtained with the Petri dish residue method in the lab.According toLC50andCTCof the insecticides,synergisms of combined application were compared.The results showed that chintin mixed with pyre-thrum extract in 1∶3a.i had significant synergisms onObolodiplosis orhiniae.The cotoxicity coffi-cients were 159.82.
