摘要
采用模糊聚类方法对仓储粮食中孳生粉螨进行分类研究;分层取样20种粮食后,分离出23种螨,并分别按带权重αi和不带权重αi两种模糊矩阵分类;结果表明采用带权重αi分类比较符合实际生境分布;以F3粉尘螨、F15小粗脚粉螨一类和F4弗氏无爪螨、F8伯氏嗜木螨一类为优势种,集中分布在特定粮食类生境中,同时伴随多种其他螨种(腐食酪螨,粗脚粉螨,家食甜螨类等),分布广泛;从而得出在仓储粮生境中既存在优势种分布,也存在多样性分布结论。
To study classification of the acaroid mites breeding in grain stocks with fuzzy cluster, 23 species of acaroid mites were isolated from 20 groups of grain stocks with the stratified sampling. Two fuzzy matrixes was obtained for classification, but the matrix with coefficient αiwas better in accord with classification, and there were main species of D.farinae , A.farris and Blomia freemani, Caloglyphus berlesei breeding in some certain grain stocks while some other species of T.pitrescentise,A.acaraus siro L and Glycyphagus domesticus, etc more generally breeding in many grains in stocks.
