棉铃虫是我省棉花蕾铃期主要害虫。以往对其各发育阶段的存亡数量及致死因子研究较少。生态学的发展,运用生命表资料已成为研究分析昆虫种群数量变动的重要方法。在前人研究的基础上,为摸清我省集中棉区棉铃虫各发育阶段的存亡率、影响消亡率的主要因子及其对种群数量变动的关系,进而 Cotton bollworm is our province cotton boll date main pests. In the past, there were few studies on the number of surviving and the lethal factor in each stage of development. The development of ecology and the use of life table data have become an important method for studying the changes of insect populations. On the basis of previous studies, in order to find out the survival rate of cotton bollworm in different developmental stages in our province, the main factors affecting the mortality rate and its relationship with population changes,
