摘要
用多种聚集度指标分析了桔小实蝇Bactrocera (Bactrocera)dorsalis (Hendel)雄成虫在番石榴和杨桃园的空间分布格局.结果表明,该虫雄成虫分布基本成分为个体群,雄虫个体间相互排斥,其密度高低影响空间分布,密度高时呈随机分布,密度低时主要是随机分布。
Spatial distribution patterns of oriental fruit fly, Bactrocera (Bactrocera) dorsalis (Hendel), male adults in two species of fruit were analyzed by some distribution parameters. The results showed that the male adults trapped by attractor in orchards of star fruit and guava distributed in groups in space and the individuals interfered each other. The spatial distribution pattern affected by the density of the male was randomly at high density and most randomly, partly aggregative at low density.
