| 摘 要： | 对黄曲条跳甲成虫的空间分布型进行测定 ,结果表明 :黄曲条跳甲成虫在菜心上的空间分布格局为聚集分布 ,符合负二项分布和核心分布 ;聚集原因主要由环境因素 (食料等 )造成 ,也与自身特性有关 .文中还根据聚集度均数 (λ)的测定结果 ,组建了序贯抽样模型和最适理论抽样数模型

| Abstract: | Spatial distribution of the adults of striped flea beetle (SFB), Phyllotreta striolata (Fabricius) was studied in the fields of Brassica parachinesis Bailey in Fuzhou. The SFB adults were highly aggregated according to the measurement of distribution pattern indices and their spatial distribution patterns fit the negative binomial distribution and the kernel distribution in terms of the determination of frequency distribution. Aggregation of the SFB adults largely resulted from environmental variables, such as the host plants, and its biological and ecological characteristics. Based on the estimation of mean aggregation (λ), a sequential sampling model and a theoretical sampling number model were set up. |
