甘薯茎线虫病的病原线虫,以往一直错误地沿用Ditylenchus dipsaci(Kühn) Filipjev,1936,国外称它为起绒草茎线虫,国内称为甘薯茎线虫。近几年来,我们对其病原线虫的形态作了较详细的观察和研究,按照de Man和Cobb公式对虫体进行了测量和计算,进行了一系列接种试验。结果认为导致甘薯茎线虫病的病原线虫不是D.dipsaci而是D.destructor Thorne,1945。在我国D.destructor首先在甘薯上找到,它不仅侵染茎部而且侵染根部和块根,造成腐烂。因此建议其中文名称为甘薯腐烂线虫或马铃薯腐烂线虫;由该虫种在甘薯上引起的病害称为甘薯腐烂线虫病。
In the past, Ditylenchus dipsaci (Kühn) Filipjev, 1936, has been mistakenly used as a pathogenic nematode for Sweetpotato stem nematodes. In recent years, we have made a detailed observation and study of the morphology of its pathogenic nematodes. We measured and calculated the parasites according to de Man and Cobb formulas and carried out a series of inoculation experiments. As a result, it was assumed that the pathogenic nematode that led to Sweetpotato stem nematode disease was not D. dipsaci but D. destructor Thorne, 1945. In our country D. destructor was first found on the sweet potato, which not only infects the stem but also infects the roots and roots, causing decay. Therefore, it is suggested that its Chinese name is the sweet potato rotting nematode or potato rotting nematode; the disease caused by the insect on sweet potato is called sweet potato rotting nematode.
