目前,防治害虫的常用施药方法有弥雾、吹雾、喷雾、喷雨、泼浇等几种,各种施药方法对害虫和天敌的影响尚无系统研究。由于害虫种间生物学特性的差异,符种施药方法对不同害虫的防效各不相同,对蜘蛛等天敌的影响程度也不一样。为了在综合防治中采用正确的施药方法,我们于1984～1986年在平湖县曹桥乡进行了各种施药方法的试验。现将试验结果整理如下。
At present, the common application methods of pest control include misting, blowing mist, spraying, spraying rain and pouring pouring. There are no systematic studies on the effects of various spraying methods on pests and natural enemies. Due to the differences in the biological characteristics of pests, the control methods of different species of pests have different effects on different pests and the effects on the natural enemies such as spiders. In order to adopt the correct method of pesticide application in comprehensive prevention and control, we carried out a variety of application methods in 1984 and 1986 in Caoqiao Township, Pinghu County. The test results are summarized below.
