福建省松材线虫病监测鉴定及其分布

2006—2009年分别在福建省松材线虫病(Bursaphelenchus xylophilus Nickle)重点监控区、重点预防区和一般预防区的重点区域设立了3 030个监测点,及时采集全省9个设区市48个县(市、区)发现的松枯死木样本,选择症状较典型和可疑松枯死木样本进行分离、鉴定。共快速分离鉴定标本176批次,计9 866个标本,其中含有松材线虫的标本2 819个,松材线虫病检出率为28.57%;鉴定样本的林分小班数2 214个,有松材线虫分布的小班690个,占31.17%。共监测出22个县级新疫点。2008年在野外首次监测到湿地松(Pinus elliottii)因感染松材线虫病后成片死亡。通过实践总结出一套松材线虫病鉴定技术。
