防治害虫试验效果的测定主要是根据虫口密度、为害程度或损失情况来衡量:如邱式邦等(1963)用颗粒剂防治玉米螟试验是在心叶末期施药后7—10天,每处理剖查玉米60-70株,以“百株虫数”和“减虫％”用作衡量防治效果的标准;郑炳宗等(1965)在心叶末期防治后11—14天剖查玉米植株的蛀孔及虫数,田间试验设计是采用随机排列,并用变量分析的统计方法来分析试验结果。根据作者的研究,潜蛀在玉米茎秆
Pest control test results are mainly based on population density, degree of harm or loss to measure: such as Qiu style (1963) with cornstarch granules control test is the end of leaf in the late 7-10 days after application, each treatment profile 60-70 plants of maize were surveyed, and the “one hundred insects” and “de-worming%” were used as the standard to evaluate the control effect. Zheng Bingzong et al. (1965) examined the moth holes of corn plants 11-14 days after the end- The number of insects, the field trial design were randomly arranged and the statistical analysis of the variables was used to analyze the test results. According to the authors’ research, the moths are eaten in corn stalks
