摘　　要：为明确松褐天牛(Monochamus alternatus)在广西的种群动态变化规律,在桂北、桂中、桂南、桂东和桂西各县设置监测点,挂放诱捕器,收集成虫并对数据进行分析。结果表明,在桂北和桂中,松褐天牛首次捕获时间为4月,桂东和桂南为1月,桂西为2月;在桂北和桂中,末次捕获时间为11月,其他地区为12月;各地区松褐天牛均有多个活动盛期。通过主成分和相关分析,气候条件为预测松褐天牛种群动态的关键因子。松褐天牛在广西世代重叠,在桂北、桂中和桂西地区1年发生1~2代;在桂东和桂南地区1年发生2~3代。To clarify change law of population dynamics of Monochamus alternatus in Guangxi,adults were col⁃lected and data were analyzed by setting orientations and hanging traps in counties of northern,central,south⁃ern,eastern and western Guangxi.Results showed that first trapped time of M.alternatus was in April in north⁃ern and central,in February in western Guangxi,and in January in eastern and southern Guangxi;last trapped time was in November in northern and central Guangxi and in December in other places.M.alternatus had mul⁃tiple activity peak periods in each region.Based on principal component analysis and correlation analysis,tem⁃perature conditions were key factors to predict population dynamics of M.alternatus.M.alternatus was genera⁃tional overlap in Guangxi,which occurred once or twice a year in northern,central and western Guangxi and twice or three times a year in eastern and southern Guangxi.
