云南松林分松墨天牛诱捕效果初报

Preliminary Report on the Trap Efficiency of Attractant on Monochamus alternatus Hope in Yunnan Pine Forests

本文通过对兴义市乌沙林场等地云南松人工林连续5年以诱捕器诱杀松墨天牛为主,并辅助其他治理方法治理林区松墨天牛的情况进行研究。试验结果表明:在试验点松墨天牛的诱捕率随着使用诱捕器诱杀次数的增加而逐渐减小,并且林区的生态环境得到了改善,松墨天牛的种群数量得到了一定的控制。同时在试验中发现了影响诱捕器诱杀得到松墨天牛的几个重要因素,并提出相应的对策。

Monochamus alternatus were trapped by attractant in some Monochamus alternatus forests located in Xingyi city for consecutive 5 years,and the catch rate（number of catches/total trapping devices） were calculated and compared among different years.The result showed that the catch rate decreased year by year,indicating that the population of the pest was controlled.Also,some factors influencing the trapping efficiency were found during the experiment and some relevant countermeasures were proposed.
