应用模糊相似优先比与模糊综合评判方法研究李园害虫与其主要天敌种群数量的相互关系。模糊相似优先比方法分析显示,小绿叶蝉的主要天敌是肖蛸蛛,其次是三突花蟹蛛;桃蚜的主要天敌是草蛉,其次是龟纹瓢虫;李叶甲的主要天敌是龟纹瓢虫,其次是异色瓢虫。模糊综合评价方法分析显示,小绿叶蝉的优势种天敌是肖蛸蛛,其次是三突花蟹蛛,其结果与模糊相似优先比的分析结果一致。
Study on the Relationship between the Population Dynamics of Liyuan Pests and Their Main Natural Enemies Using Fuzzy Similarity Priority Ratio and Fuzzy Comprehensive Evaluation. The analysis of fuzzy similar precedence ratio method showed that the main natural enemy of the green leafhopper was Hymenoptera, followed by the Euonymus trifoliata. The main natural enemies of the Myzus persicae were grass weeds, followed by the turtle ladybugs. Ladybugs, followed by heterochromatic ladybugs. The results of fuzzy comprehensive evaluation showed that the predominant species of the green leafhopper was Xiaodao spider, followed by the three species of Crab spider mite. The results were consistent with those of the fuzzy similarity priority.
