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。
Spatial patterns of adults of mulopenicillin mites were analyzed by using six aggregation indexes and the sampling techniques were discussed. The results showed that the spatial pattern of rust mite mites in winter was clustered. The most suitable sampling site in the field was the leaf axils of upper and middle leaves of plants. A sequential sampling scheme for estimating the density of overwintering adults was proposed.
