柠条重要害虫四线奇尺蛾天津亚种幼虫的空间分布研究
|
摘要
四线奇尺蛾天津亚种是近几年新发现的危害柠条的重要害虫,研究四线奇尺蛾种群的空间格局和抽样技术,可为该害虫的危害调查与防治提供理论依据。本文应用6个聚集指标和Taylor幂法则及Iwao的m~*-m回归分析法,对四线奇尺蛾天津亚种幼虫的空间分布型和抽样技术进行了研究,并做了影响因素分析。结果表明:四线奇尺蛾天津亚种幼虫在6个样地均呈聚集分布,分布的基本成分是个体群,通过分布型参数,采用Iwao法计算出了在不同精度下幼虫抽样数公式和序贯抽样模型,该模型可为四线奇尺蛾天津亚种的预测预报及防治提供理论依据。
Chiasmia saburraria richardsi is an important pests in Caragana korshinskii newly discovered in recent years in China, studies on spatial distribution pattern and sampling technique can provide theoretical base for the damage survey and control of C. saburraria richardsi. In this study, the spatial distribution pattern of the larvae of C. saburraria richardsi in C. korshinskii was analyzed with six aggregation indexes, Taylor's power law and Iwao's distribution function. The results showed that the spatial distribution pattern of the larvae of C. saburraria richardsi in C. korshinskii were all aggregated in six samples, and the basic component of the distribution was individual colony. Through the distribution parameters, used Iwao's method to establish the optimal sampling equation and sequential sampling equation in field under different precision. This equation may provide the basis for prediction and control of C. saburraria richardsi.
