| 摘 要： | 松材线虫病是一种毁灭性的森林病害,不同地区的松材线虫在形态特征方面有一定的差异.采用扫描电子显微镜对来自湖南、广东两地3个株系松材线虫进行了形态观察比较.结果表明:这3个株系的松材线虫成虫的头部、尾部形态特征无明显差异,幼虫和成虫的唇区与体部都出现缢缩;松材线虫口针的开口端呈一斜面;雄性成虫尾部交合伞呈“M”型.这些特征都是在过去的研究中没有描述过的,可为松材线虫的形态研究提供参考依据.

| Abstract: | Pine wilt disease is destructive to forests.B.xylophilus has different characteristics in morphology in different areas.In this paper,three strains of B.xylophilus,collected from Hunan and Guangdong,were observed and compared by SEM.The result shows that the characteristics of head and tail of the three strains had no obvious differences;that the lip regions of both their larva and adult were constricted and on observation of B.xylophilus' stylet,its end was an inclined plane;and that he bursa of adult male presented the shape "M".These characteristics of B.xylophilus were described for the first time, which would provide a significant basis for the morphologic studies of B.xylophilus. |
