摘　　要：巴氏新小绥螨在江西安远的高峰期出现在9～11月之间。通过运用聚集型指标、Taylor幂法则和Iwao的m*-直线回归分析法,得出巴氏新小绥螨成螨空间分布型为聚集分布。当样方平均密度在2.89头以上时,其聚集原因是由于巴氏新小绥螨本身的聚集习性和环境条件或由其中一个因素引起;当样方平均密度在2.89头以下时,聚集原因是由于环境条件引起的。最适抽样数N=2.125+69.125/。Peak period of Neoseiulus barkeri happened from September to November in Anyuan Jiangxi.Several aggregation indices、Taylor power law and m＊- liner regression equation of Iwao were used to determine tha spatial distribution type of N.barkeri,and the spatial distribution type was assembly distribution.The aggregation was caused by both the N.barkeri biological characteristics and the environmental factors when  is above 2.89.The aggregation was caused by the environmental factors when  is blow 2.89.Based on these analyses,the optimum sampling number was established as the following：N=2.125＋69.1251.
