两种引诱剂诱捕松墨天牛效果比较

Comparison of trapping effect between two kinds of attractants on Monochamus alternatus

在松材线虫病发生区同一林班、同一期限 ,采用相同的方法 ,对粤产PE型引诱剂与浙产M99型引诱剂 (配方不同 )诱捕松墨天牛的综合效果进行测试比较。结果表明 :在相同的诱捕期内所释放消耗的用量没有明显差异 ,PE型诱捕天牛的效率比M99高 2 5 5 % ,且诱虫专一性较强 ;M99在林间使用较简便 ,价格较便宜 ,防治成本明显低于PE。

The experiment was made with the same method on the effect of two kinds of attractants on Monochamus alternatus in the same pine wood nematode(Bursaphelenchus xylophilus)infested stand and during the same period.The PE type and M99 type attractants were developed in Guangdong Province and Zhejiang Province separately.The result showed the consumption of the two attractants was nearly equal in the same period,but the efficiency of PE attractant was 25 5% higher than that of M99 and the specificity of PE was superior to M99.But M99 was more convenient than PE in application and its cost was obviously lower.
