应用空间分布型统计参数IwaoM—X模型中α,β及6个聚集指标分析柑橘全爪螨的空间格局,结果表明,柑橘全爪螨的空间格局为聚集型。在此基础上,研究提出了估算柑橘全爪螨在不同虫口密度情况下的理论抽样数。
Spatial patterns of Citrus grandis mites were analyzed by α, β and six aggregation indexes in the spatial distribution statistical parameter IwaoM-X model. The results showed that the spatial pattern of the citrus red mites was aggregated. On this basis, the study proposed the theoretical sampling number for estimating the total mite mite at different insect population densities.
