作者于 1 996年对二斑叶螨 (TetranychusurticaeKoch)、朱砂叶螨 [T .cinnabarinus(Boisdural) ]和山楂叶螨 (T .viennensisZacher)进行了三氯杀螨醇、甲氰菊酯、哒螨酮、霸螨灵等 4种杀螨剂的毒力测定 ,并对 3种叶螨在LC50 和LC95水平上 ,比较了相互之间的毒力差别。结果表明 ,二斑叶螨的毒力最高 ,朱砂叶螨次之 ,山楂叶螨毒力最低。
In 1996, the authors investigated the effects of dicofol, fenpropathrin, pyridaben, tyrants mites on Tetranychus urticae Koch, T. cinnabarinus (Boisdural) and T. viennensis Zacher And other four kinds of acaricide virulence determination, and three kinds of spider mites in LC50 and LC95 levels, compared with the virulence differences between each other. The results showed that two-spotted spider mite had the highest virulence, followed by Tetranychus cinnabarinus and hawthorn mite had the lowest virulence.
