| 摘 要： | 光肩星天牛是糖槭、杨、柳、榆等树种的主要蛀干害虫之一。通过测定6种不同的判断空间分布格局的聚集度指标，并应用Taylor幂法则和Iwao回归分析法，得出光肩星天牛幼虫空间分布型为聚集分布，聚集原因是由本身的生物学特性和环境异质性共同作用引起的；另外，根据距离干基部的不同位置划分为3个高度，得出不同高度的虫口数量在1％水平达显著差异，且2m以上的虫口数量最多。

| Abstract: | Anoplophora glabripennis is one of the major pests which damage Acer saccharum,poplar,willow,Ulmus pumila.Six kinds of aggregation indices of distribution pattern were examined by using Iwao's regression analysis and Taylor's power law.The result shows that the larvae spatial distribution pattern of Anoplophora glabripennis is aggregation distribution;the aggregation were caused by both the insect's biological characteristics and the environmental heterogeneity;in addition,3 different positions away from th... |
