摘要(Abstract)：
采用挂设诱捕器的方式对福建省惠安县松褐天牛发生情况开展了种群动态监测和分析。结果表明，4—6月松褐天牛成虫诱捕量呈快速上升趋势，7—11月逐渐下降，成虫最高诱捕量出现在5—6月，5—8月的成虫发生量累计占年发生总量的80.10%,成虫活动期为4—11月。涂寨镇的成虫诱捕量显著低于黄塘镇、螺阳镇和山霞镇的。黄塘镇、螺阳镇的小班郁闭度同诱捕量存在显著正相关(P<0.01),涂寨镇、山霞镇的小班郁闭度同诱捕量不存在显著相关性(P>0.05)。
The population dynamics of adult Monochamus alternatus Hope in Huian County were monitored based on trapping. The results showed that the numbers of M. alternatus adults trapped increased rapidly from April to June, and thereafter gradually declined from July to November. The numbers of captured M. alternatus adults peaked between May and June, and the numbers trapped between May and August accounted for 80.10% of the total annual number trapped. On the basis of these results, we established that the active period of M. alternatus adults is from April to November. Furthermore, the numbers of M. alternatus adults trapped in Tuzhai Town were found to be significantly lower than those trapped in Huangtang, Luoyang and Shanxia towns. The canopy density was highly significantly positively correlated with the numbers of M. alternatus adults trapped in Huangtang and Luoyang towns(P<0.01), but was not significantly correlated in Tuzhai and Shanxia towns(P>0.05).
