通过对丽腹弓角鳃金龟(Toxospathius auriventris Bates)成虫空间分布格局的测定,应用聚集度指标法、Taylor幂法则和Iwao回归法对丽腹弓角鳃金龟成虫的空间分布型进行分析和检验,以期对该害虫实施预测预报及防治提供科学依据。结果表明,丽腹弓角鳃金龟成虫在林芝农牧林交错带呈聚集分布,分布的基本单位是个体群,而且个体间相互吸引。种群数量动态研究显示,丽腹弓角鳃金龟种群数量除了在未开垦的天然灌丛草地生境外,在其他样地表现基本一致。
The spatial distribution patterns of adult adults of Toxospathius auriventris Bates were determined by using the method of aggregation index, Taylor’s power law and Iwao regression analysis. In order to provide a scientific basis for the prediction and prevention of pests. The results showed that adults of the gill beetle were aggregated in the agroforestry system of Linzhi, and the basic units of distribution were individual groups, and the individuals attracted each other. The dynamic population dynamics showed that except for uncultivated natural shrub grass habitat, the population of the gills population was equal in other plots.
