摘　　要：应用6个聚集度指标分析了越冬柑桔锈螨成虫的空间格局,并对抽样技术进行了探讨。结果表明,越冬柑桔锈螨成虫的空间格局为聚集型;田间的最适抽样部位是植株上、中部叶片的叶腋处。提出了越冬成虫密度估计的序贯抽样方案。The spatial pattern of overwintering adult citrus rust mites (Phyllocoptes obleivorus Ashmead) was measured with six aggregation indices, and the sampling technique was studied. The results showed that (1) the spatial pattern is aggregated distribution, and (2)the optimum sampling position is the upper and middle parts of the canopy. Furthermore, the sequential sampling method for its density estimation was proposed.
