目的 调查淮南地区食用菌孳生粉螨种类及生物多样性. 方法 分别于1~5月份、8~12月份(每月1次) ,从食用菌种植基地采取6种食用菌及其培养料. 采用直接镜检法、避光爬附法和电热集螨法分离粉螨、制片与鉴定. 计算样本中物种多样性( Shannon-Wiener 指数)、物种丰富度( Margalef指数)和物种均匀度( Pielou指数). 结果 淮南地区食用菌中共分离出5种粉螨,隶属于3科4属. 1年中粉螨的物种多样性指数为1. 606 ~1. 683,其中3、4 月份最高,1月份最低;物种丰富度指数为0. 502~0. 982,其中4月份最高,8月份最低;物种均匀度指数为1. 003~1. 493,其中8月份最高,11月份最低. 结论 淮南地区食用菌中有多种粉螨孳生. 对此应采取有效措施控制粉螨孳生,以防食用菌质量和产量下降.%Objective To investigate the biodiversity of acaroid mites breeding in the edible mushrooms in Huainan of Anhui province, China. Methods Six species of edible mushrooms, together with their composts, were collected from different mushroom cultivation plants from January to May and August to December( Sample collection was car-ried out once each month) . The acaroid mites were separated and identified from the samples with stereoscopy and microscopy, galvanothermy and tullgren techniques. The richness index, biodiversity and species evenness were es-timated with Shannon-Wiener index, Margalef index and Pielou index, respectively. Results Five species of aca-roid mites, belonging to 4 genera under 3 families, were identified from the total samples. Annual Shannon-Wiener indices were from 1. 606 to 1. 683, and peaked in March and April, but were lowest in January. The Margalef indi-ces were ranged from 0. 502 to 0. 982, which was highest in April and lowest in August. Pielou indices stayed be-tween 1. 003 and 1. 493, which was maximal in August and minimal in November. Conclusion A variety of spe-cies of acaroid mites breed in the edible mushrooms in Huainan, for which effective measures should be taken to prevent the mushrooms from quality degradation and yield reduction.
