| 摘 要： | ４种扩散试验法证明氧化乐果，杀虫脒，溴氰菊酯和氰戊菊酯对朱砂叶螨有较强的刺激扩散作用，扩散率基本随药剂浓度增加而升高，扩散高峰在施药后２４ｈ，叶螨对药剂处理叶（株）有很强的忌避性。３种激发生殖力试验证明，１１种农药中，增殖最大又持久的４种，且逐日上升；抑制力高又持久的２种，并逐步下降；５种居中，即先抑制后增殖，而且增殖作用还包括直接和间接两种。这些可能是引起叶螨再猖獗的重要原因。

| Abstract: | Four methods of test of dispersal proved that the omethoate, chlordimeform, deltamethrin and fenvalerate were provided with strong stimulus effect on the dispersal of Tetranychus cinnabarinus(Boisduval) , the dispersal rates raised in connection with the pesticide concentrations. The peaks of dispersal were all at 24h after application and the mite has very strong avoiding reaction for treated leaves or plants. Three reproductive capacity tests showed that among the eleven insecticides, four had most strong and lasting of stimulative increase, and raised every day ;two possessed strong and lasting restraint fecundity, and fell step by step; and five between these two parties ,i. e. half restraint , half increase. Besides, the increase effect included some direct and some indirect. These may be one of important factors of resurgence of mites. |
