The spatial distribution patterns of overwintering larvae of the pine caterpillar were studied by means of index of aggregation regression modle and frequency distribution. The result showed an aggregation distribution pattern for the larvae. Under low population density the distribution of the larvae obeyed Neyman distribution. In a single pine tree the larvae exhibited negative binomial distribution. The larval density between verticillate branches varied greatly and it should be divided...

The spatial distribution patterns of overwintering larvae of the pine caterpillar were studied by means of index of aggregation regression modle and frequency distribution. The result showed an aggregation distribution pattern for the larvae. Under low population density the distribution of the larvae obeyed Neyman distribution. In a single pine tree the larvae exhibited negative binomial distribution. The larval density between verticillate branches varied greatly and it should be divided into three groups. Different sampling methods were compared and the Z-shaped method found to be the best. The number of trees form which we took samples for survey was 24.

本文运用聚集度指标法、回归模型法和频次分布法研究了马尾松毛虫越冬代幼虫的空间分布型.结果表明幼虫的分布型符合聚集分布.低密度情况下的幼虫服从Neyman A型分布,幼虫在单株树上的分布服从负二项分布,各轮枝层虫口密度差异显著,可将其划分为3组.比较6种不同的抽样方法,以Z字形法为最好,抽样数量以24株为宜.

This paper deals with the spatial distribution patterns of the larvae of Diorycitria rubella in masson pine and loblolly pine using the frequency distribution analysis and aggregation indices.The results indicate that it was an aggregation distribution pattern,especially the negative binomical distribution.The aggregation distribution pattern of the larvae was not caused by their habit,but by some environmental factors.

应用频次分析法和聚集度指标法对微红梢斑螟在马尾松和火炬松林中的空间分布进行研究.微红梢斑螟在马尾松和火炬松林中的分布为聚集分布,主要是负二项分布.其聚集是某些环境作用所致,而不是微红梢斑螟本身的聚集习性.

This paper deals with the spatial distribtion of the larvae of Dioryctria rubella in masson pine and slash pine with diffusion index and regression analysis.Aggregation indices indicate the larva distribution is aggregation distribution pattern,and regression analysis indicates its distribution is negative binomial.The larvae attract each other.The main composition of distribution is individual community.In the community,the distribution of the larvae is random.

应用扩散型指数和回归分析方法对微红梢斑螟幼虫在湿地松和马尾松林中的空间分布进行了研究.聚集度指标说明微红梢空间分布型均属于聚集分布;回归分析说明其分布是负二项分布.个体间相互吸引,分布的基本成份为个体群,群体内分布是随机的.
