摘　　要：2015—2016年连续2 a在同一侧柏幼龄林内开展了饵木诱杀双条杉天牛试验,运用统计方法分析了饵木诱杀双条杉天牛数量与气象因子的相关关系。结果表明,双条杉天牛诱集量呈多峰动态变化,诱集量与温度显著相关,并建立了双条杉天牛诱集日累积百分率与温度回归方程。连续2 a的饵木诱杀减少了天牛种群数量,降低了被害株率,证明饵木诱杀法既可监测天牛成虫羽化期种群数量变化,又可作为一种防治方法。Experiment of attracting and killing Semanotus bifasciatus with trap log were carried out in the same place in young forest stand of Platycladus orientalis in 2015 and 2016. The relationship between the amount of trapping and killing S. bifasciatus with log section and meteorological factors were analyzed by statistical methods. The results showed that the amount of attracted S. bifasciatus had dynamic changes of multi-peak curse,and changed significantly under different temperatures. Using trap log for two consecutive years reduced number of pest population and attacked trees rate,which showed that it could not only monitored population quality of the pest in emergence period,but also served as a method of prevention.
