| 摘 要： | 2015年在海南省豇豆上发现中国新记录种暗褐露尾甲Epuraea picinus。本研究运用5种聚集度指标(m*/m、c、k、I、Ca)和两种回归模型(Taylor幂法则和Iwao回归分析法)研究分析了海南省7个乡镇8块豇豆地上的暗褐露尾甲的空间分布型。结果表明,暗褐露尾甲成虫在海南豇豆上在垂直空间和水平空间均为聚集分布,0.83头/百株时为随机分布。

| Abstract: | The spatial patterns of distribution of Epuraea picinus were studied. The investigation were included 8 cowpea fields of 7 counties. There have been assessed by 5 types of aggregation indices, taylor power principle analysis and Iwao index of dispersion. The results suggests that the spatial patterns of distribution of adult E. picinus on cowpea showed aggregated distribution in vertical space, while aggregated distribution in horizontal space, and random distribution only appeared when the population density reaches 0.83 per hundred crops |
