1984—1986年,我自治区植保站组织我区13个地、州、县测报、农技站的同志开展了五种害虫的作物产量损失估计试验和防治指标制订工作。这五种害虫是:黄地老虎、冬麦地老虎、麦长管蚜、棉铃虫和牧草盲椿象。同时开展多种害虫的防治指标试验研究工作,对全区来说还是第一次,因此被列为自治区重大科研课题之一。该课题于1987年5月通过自治区的鉴定。经过三年田间试验和产量结果分析等,得出以下五种害虫的虫量和作物产量损失率之间
From 1984 to 1986, the Plant Protection Station of our autonomous region organized comrades from 13 prefectures, counties and cities in our district to carry out crop yield loss estimation tests and prevention and control targets for five kinds of pests. The five pests are: yellow tiger, winter wheat tiger, wheat aphid, cotton bollworm and pasture blind stinkbug. At the same time carry out a variety of pest control indicators of experimental research, the first time for the region, it was listed as one of the major research projects in the autonomous region. The subject in May 1987 through the identification of autonomous regions. After three years of field trials and analysis of yield results, it was concluded that the following five insect pest insects and crop yield loss rate between
