桔园束管食螨瓢虫ＳｔｅｔｈｏｒｕｓｃｈｅｎｇｉＳａＳｉｊｉ各虫态及种群空间分布的基本成份为个体群．个体间相互吸引；幼虫、蛹、种群呈聚集分布，成虫为均匀分布．幼虫、蛹的聚集由外界因素所致，而种群的聚集由外界因素和其自身的聚集行为所致．各虫态及种群的个体群大小随各自平均密度的增加而呈线性递增．此外，本文还讨论了种群的序贯抽样技术和最适理论抽样数．
Citrus bundle tube diet mites ladybug StethoruschengiSaSiji various insect states and population spatial distribution of the basic components for the individual groups. Individuals attract each other; larvae, pupae, population aggregation distribution, adult uniform distribution. The accumulation of larvae and pupae is caused by external factors, while the aggregation of the population is caused by external factors and their own aggregative behavior. The population size of each insect population and population increased linearly with the increase of average density. In addition, this article also discusses the sequential sampling technique and the optimal theoretical sampling number of the population.
