| 摘 要： | 香蕉假茎象甲成虫的空间分布规律研究结果表明,香蕉假茎象甲成虫在香蕉园呈较强的聚集分布,平均拥挤度、个体群平均大小随成虫密度增大而增大,个体群所占空间随密度增大而减小;成虫聚集分布主要是由于蕉园环境的异质性引起的。建立了成虫最适理论抽样数公式,提出了为防治决策服务的序贯抽样模型。

| Abstract: | The spatial pattern of banana pseudostem weevil (Odpoiporus longicollis) was studied. The results showed that adults of the weevil were aggregately distributed in banana plantations. With an increase in adult density, the mean crowding index and the mean group index were higher, but the space of the colony became smaller. The environmental factors influenced the aggregation of the adult. The equation for the most suitable sampling quantity and the models of the sequential sample were built up. |
