摘要
锈色粒肩天牛Apriona swainsoni(Hope)是危害国槐的重要检疫性有害生物。通过对受害国槐抽样调查,系统研究了锈色粒肩天牛种群的自然死亡原因。通过种群趋势指数(I)的分析,探明了锈色粒肩天牛种群的自然消长规律,制定了种群生命表,为该虫的预测预报和可持续控制提供了科学依据。
Apriona swainsoni （Hope） was an important and quarantine borer attacking Sophora japonica. Based on the sample survey on the infested Sophora japonica, the reasons of natural death of the Apriona swainsoni population were studied. The regularity of natural population fluctuation was discovered and the population life table of the pest was provided with the analysis of the population trend index （Ⅰ）.
