Abstract: Objective To investigate the relationship between the community structure of acaroid mites and their habitat in the breeding environment for Eupolyphaga sinensis Walker. Methods One hundred samples were collected at several points in a E. sinensis Walker farm in North Anhui province, China. The collected samples underwent isolation, identification, and counting as well as analysis of the ecological diversity. Results Eight species of acaroid mites, belonging to 6 genera under 3 families, were identified from the breeding environment, with a mean breeding density of (95.07?9.54) mites/g, a richness index (Margalef index) of 2.127, an evenness index (Pielou index) of 0.939, a diversity index of 1.972, and a dominance index of 0.872. The community of acaroid mites consisted of Caloglyphus berlesei (69.3%), Tyrophagus putrescentiae (10.6%), Acarus siro (9.2%), Dermatophagoides farinae (5.4%), and other species (5.5%). Conclusion Acaroid mites multiply seriously in the breeding environment for E. sinensis Walker in North Anhui province. Of the acaroid mites, C. berlesei is the dominant species and tends to live on decayed materials.

摘要: 目的 调查地鳖养殖环境中螨类的群落结构和生境关系。方法 对皖北地区某地鳖虫养殖场多点采样,将采集的100份样本进行分离、鉴定和计数,并对生态多样性进行分析。结果 检出8种螨,隶属于3科6属;平均孳生密度(95.07±9.54)只/g,丰富度指数2.127,均匀度指数0.939,多样性指数1.972,优势度指数0.872;孳生螨群落以伯氏嗜木螨为主,其群落构成比为69.3%;各主要螨种构成比:伯氏嗜木螨69.3%,腐食酪螨10.6%,粗脚粉螨9.2%,粉尘螨5.4%,其它螨类5.5%。结论 皖北地区地鳖养殖环境中的螨类孳生情况严重,以伯氏嗜木螨为主,且该螨具有明显的亲腐性。
