粘虫是东台地区三麦上主要害虫,过去防治它主要是应用高效高残毒农药。但农本高、残毒严重。1976年我们在东台县开门办学期间,在当地贫下中农与革命科技人员的指导下,就粘虫的防治开展了一些工作,现把主要体会小结如下: 一、小草把诱蛾灭卵效果好 1.一次插把和二次插把的效果 安丰公社十三队部分田块在发蛾始盛期插把(10多很稻草对折扎成小把绑在小棒上)一次。一般高出三麦半尺许。蛾盛末期后收把。部分田块插二次把,在蛾高峰时换把一次。而新新大队第三生产队只插把不收把,根据后来虫量调查,只插不收的田块,虽然每亩把数比换把田块多,同样长势长相的小麦田,虫口密度比插一次把、插二次把的田块虫量分别高出2.5倍、7.8倍,大麦田分别高出2.57倍、8.99倍(表1)。
Mythimna separata is the main pest on the three wheat in Dongtai area. In the past, it was mainly applied to pesticide with high efficiency and high residue. However, this high agricultural, serious residual poison. In 1976, when we started school in Dongtai County, we conducted some work on the prevention and control of armyworms under the guidance of the poor peasants and technicians in the areas under the guidance of the poor. We conclude the main findings as follows: 1. A plug and the effect of the second plug Anfeng commune thirteen teams of some plots in the initial stage of hair moth inserted (more than 10 very straw tied into small tied to a small stick) once. Generally higher than three wheat half feet Xu. After the end of the moth Sheng put. Part of the field insert the second time, when the moth peak to change again. The new production brigade only inserted the new team will not accept, according to later investigation of the amount of insects, only non-payment of plots, although the number of plots per mu for more than the field, the same growing wheat fields, population density The number of pests in the field was 2.5 times and 7.8 times higher than that of the second field and 2.57 times and 8.99 times higher than that of the second field (Table 1).
