| 摘 要： | 草原害虫药剂防治受多种环境因子的影响,以单一的害虫死亡率所反映的试验结果在实际应用中多受限制。本文以牧草害虫——白茨粗角萤叶甲为防治对象,以植被、害虫、天敌、成本四大方面的影响效应选取8项评判指标,采用综合评判、加权海明距离等模糊数学方法,对5种农药12项处理的防治效果进行评判。结果表明,采用2.5％敌杀死,5毫升/亩;40％双效菊酯,5毫升/亩;20％杀灭菊酯,10毫升/亩进行超低容量喷雾,具有较好的综合效果。

| Abstract: | In this paper,eight appraisal indices were used in fuzzy syntheti-cal multi-factor analyses for determining the control efficacies oftwelve treatments with five insecticides.The results showed that thesynthetical effects of ultra-low-volume sprayings with 5 ml/mu of 2.5?cis,5 ml/mu of 40% Shuangxiao-methrin,or 10 ml/mu of 20%sumicidin were desirable. |
