生命表是用于揭示昆虫种群数量变动与环境因子关系的一种方法,它能系统而又规范化地提供种群动态资料,利用此信息,人们进而进行数学摸拟,分析其影响数量变化之关键因子与关键时期,是害虫数量预报重要手段之一。国外Pearl 和Parker(1921)最早建立了果蝇实验种群生命表,Murris 和Miller(1954)又组建了第一个自然种群生 The life table is a method for revealing the relationship between the quantity change of insects and environmental factors. It can systematically and systematically provide the population dynamic data. Using this information, people conduct mathematical simulations to analyze the key factors that affect the quantity change And the critical period, is one of the important means of forecasting the number of pests. Pearl and Parker (1921) in foreign countries established the life table of experimental population of fruit flies as early as possible. Murris and Miller (1954) formed the first natural population
