昆虫空间分布型是指一种昆虫群体在一定环境条件下的空间分布结构。这种分布结构是昆虫种的遗传特性与生活环境条件相互联系的结果。明确昆虫的分布型,可以了解其生物学特性和生态学特征,为确定抽样技术、取样数量提供理论依据。对害虫发生的预测预报及其防治对策的抉择均有指导意义。为了研究松突圆蚧的发生规律和防治工作中能够采取较合理的取样方法和取样数量。我们运用几种聚集度指标法和比较频次
Insect spatial distribution refers to a population of insects in certain environmental conditions of the spatial distribution structure. This distribution structure is the result of the interrelationship between the genetic characteristics of insect species and living conditions. To clarify the distribution of insects, we can understand its biological characteristics and ecological characteristics, to provide a theoretical basis for determining the sampling technique and sampling quantity. Prediction of pest occurrence and prevention and control options have guiding significance. In order to study the law of Ocimum pine crassa and prevention and control work to take a more reasonable sampling methods and sampling number. We use several measures of aggregation index and frequency comparison
