摘要

2022年，在华盛顿和俄勒冈州对影响大麻的植物寄生线虫进行调查时，发现一种Pratylenchus sp.寄生在大麻根上。形态学、形态计量学和分子技术证实了从大麻根中提取的线虫是Pratylenchus渗透物。在温室中进行的致病性测定证实，大麻是穿透假单胞菌的宿主，接种后60天的平均繁殖因子为2.2。据我们所知，这是P.pentans在美国首次对大麻进行研究。关键词：DNA，鉴定，形态学，Pratylenchus pentrans，大麻资助：该项目由美国农业和社会服务部NACA拨款2072-201000-056-004-S资助。

First report of the root-lesion nematode, Pratylenchus penetrans, parasitizing hemp (Cannabis sativa) in the United States

In 2022, during a survey of plant-parasitic nematodes affecting hemp in Washington and Oregon, a Pratylenchus sp. was found parasitizing hemp roots. Morphology and morphometrics as well as molecular techniques confirmed the identity of the nematodes extracted from hemp roots as Pratylenchus penetrans. A pathogenicity assay done in the greenhouse confirmed hemp as a host to P. penetrans with an average reproduction factor of 2.2 after 60 days post inoculation. To our knowledge, this is the first report of P. penetrans on hemp in the United States. Key words: DNA, identification, morphology, Pratylenchus penetrans, Cannabis sativa Funding: This project was funded by USDA-ARS NACA Grant no. 2072-21000-056-004-S.
