| 摘 要： | 为明确桑天牛（Apriona germari Hope）越冬幼虫的空间分布，采用6种聚集度指标（m*/m，C，k，Iδ，I，CA）和2种回归模型（Taylor的幂法则和m*-m）测定其空间分布，并利用Blackith种群聚集均数λ解析该幼虫种群的聚集成因。结果表明，其呈均匀分布，建立了桑天牛越冬幼虫抽样数公式（N=t2（1.0097m-0.1971）/D2）和序贯抽样模型（T（n）=0.2n± 0.4405），该模型可为桑天牛的预测预报及防治提供理论依据。

| Abstract: | The spatial distribution patterns of overwintering larvae of Apriona germari larva in Morus alba were studied using six spatial distribution pattern analysis methods（m*/ m， C， k， Iδ， I， CA）and two regression equations（Taylor power and m*-m）， the assembling reasons were analyzed with average aggression size λ. The results indicated that spatial distribution patterns of Apriona germari larva population was in uniform distribution. The optimal sampling equation（N=t2（1.0097m-0.1971）/D2） and sequential sampling equation（T（n）=0.2n±0.4405） were established. This paper may provide the basis for prediction and control of Apriona germari. |
