气象因子对马尾松角胫象诱捕效果的影响研究

Effects of Meteorological Factors on Trapping Shirahoshizo patruelis

[目的]研究气象因子对蛀干类害虫引诱剂诱杀马尾松角胫象的影响,为该害虫的监测和预报工作提供技术支撑。[方法]2006～2008年,在大北地溪林场进行蛀干类害虫引诱剂诱捕马尾松角胫象试验,对诱捕到的马尾松角胫象数量与15个气象因子进行通径分析。[结果]影响马尾松角胫象诱捕效果的气象因子为观察日前12d内的平均气温、平均最低气温、平均最高气温、平均相对湿度、平均最小湿度和平均水汽压。[结论]该研究结果可为马尾松角胫象的监测和预报工作提供参考。

[Objective] To study effects of meteorological factors on trapping Shirahoshizo patruelis and provide technical supports for the monitoring and forecasting.[Method] The trapping experiment of Shirahoshizo patruelis by attractant was performed in Xianju DaBei Dixi forestry center during 2006-2008.The path analysis of 15 meteorological factors and the amount of total trapped insects was then carried out.[Results] The meteorological factors？impacting the effect of trapping were as follows：mean temperature,mean minimum temperature,mean maximum temperature,average relative humidity,mean minimum humidity,and average vapor pressure.[Conclusion] This study has provided a reference for the monitoring and forecasting of Shirahoshizo patruelis.
