| 摘 要： | 通过对梨瘿华蛾空间分布型及垂直分布的研究，发现此虫的分布为具有公共Ｋ值的负二项分布：聚集原因由成虫活动和产卵习性所引起，聚集强度随种群密度的升高而增加，该虫在树冠外围的南方位与上部密度较大。为此虫的抽样调查和防治提供了理论依据

| Abstract: | tudied through the spatial and vertical distribution of Sinitinea pyrigolla Yang,it was found that the spatial distribution of the insect belong to the negative binomial distribution of common numerrical value K;The aggregation was brought by the habits and characteristics of the adult′s activity and oviposition;The intensity of aggregation enhances with going up of the density of the population.The density of the insect is larger in the upper and southern part of the crown′s periphery.The result provides scientific basis for the contral and the sampling investigation of the insect. |
