枇杷园蜘蛛混合种群空间分布型的动态分析

Dynamics of Spatial Distribution of Mixed Spider Populations in Loquat Orchard

枇杷园蜘蛛混合种群的空间分布型在不同季节存在差异,其空间分布型主要由枇杷园蜘蛛本身的生殖水平、游猎型和定居型数量的多寡,主要目标害虫的数量及分布,气候环境的变化及其越冬生态习性,枇杷园蜘蛛的种群密度及其种间竞争程度决定。

The spatial distribution of mixed spider population in loquat orchard was different during different seasons. The main factors influencing the spider spatial distribution in loquat orchard were their reproduction level, variation of habitats, the number of net-weaving spiders and wandering spiders, the number of main target pests and their distribution, the density of spider population and the extent of interspecitic competition in loquat orchard and their ecological habit of overwintering.
