种群是昆虫在自然环境中存在的基本形式,其在空间的结构形式(即空间分布型)常因昆虫种类、虫态而不同,随虫口密度大小而变化.了解昆虫的空间分布型不仅有助于提高田间调查技术和试验设计的精确度.还可以通过分布型来揭示昆虫的生活习性以及对环境条件的适应程度,提高对昆虫种群数量消长的分析.因此,植物保护工作者越来越重
Population is the basic form of insects in the natural environment, its spatial structure (ie, spatial distribution) often due to insect species, insect state and vary with the density of insect population changes. Understanding of insect spatial distribution is not only helpful To improve the accuracy of field survey techniques and experimental designs, and to reveal the habits of insects and their adaptation to environmental conditions through distributional patterns, and to improve the analysis of insect population declines. As a result, plant protection workers are becoming heavier and heavier
