| 摘 要： | 在白榆林内采用定点追踪观察并结合查迹判断的方法，对光肩星天牛自然种群动态作了调查并组建生命表进行分析后得出：其种群趋势指数为３．９３；卵期和Ⅰ期幼虫期是其整个生活世代中的薄弱环节，是防治的有利时期；Ⅰ期幼虫的微生物寄生是影响种群趋势指数最大的一个因素；并对各虫期的发生量进行了预测

| Abstract: | The natural population life table of Anoplophora glabripennis occurred Ulmus pumila from 1992 to 1994 was completed by observing the life courses of many fixed individuals of the longicorn and identifying mortality factors by tracing investigation.The analysis of the life table showed that the tendency index number of the longicorns population is 3.93, and during its life time the phase of eggs and the first period of larva (under the bast of a trunk) are two week periods in which the wood borer can be controlled best to all phases. |
