摘要
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。
The correlations of the major pests and the dominant natural enemies on quantity in plum orchards were analyzed by the method of fuzzy-similitude-priority （FSP） and fuzzy-judgement （FJ） in this paper. The results of FSP showed that the dominant natural enemy of Emposca larescens, was Tetragnathida,Misumenops tricuspidatus secondly ; The dominant natural enemy ofMyzus persicae was Chrysopa sinica, Propylaea japonica secondly; The dominant natural enemy of Cleoporus variabilis was Propylaea japonica ,Leis axyridis secondly. The results of FJ showed that the dominant natural enemies of Emposca larescens, was also Tetragnathida. The results of FSP and FJ also showed the same trend.
