昆虫在自然界以种群形式存在。种群内的个体分布具有一定的空间结构,即昆虫空间分布型。研究昆虫种群分布型,一方面可为我们揭示出昆虫种群空间结构特征;另一方面能为野外调查简化抽样技术,便于制定确切的抽样的方法。对于确定不同虫口密度和不同允许误差条件下的抽洋数量,提高测报质量和防治技术,特别是对分析防治效果,研究种群数量消
Insects exist as populations in nature. Individual distribution within the population has a certain spatial structure, that is, spatial distribution of insects. Studying insect population distribution can not only reveal the spatial structure characteristics of insect populations on the one hand, but also simplify the sampling technique for field investigation and facilitate the development of exact sampling methods. For determining the number of parasites under different insect population density and different allowable errors, improving the quality of measurement and prevention and control techniques, especially for analyzing the effect of prevention and treatment,
