Description of Bursaphelenchus ulmophilus sp. n. (Nematoda: Parasitaphelenchinae) associated with Dutch elm disease of Ulmus glabra Huds. in the Russian North West
A new species, Bursaphelenchus ulmophilus sp. n., from the hofmanni group is described morphologically and molecularly. This nematode species was found associated with Dutch elm disease of Ulmus glabra in parks of St Petersburg, Russia, and is vectored by adults and larvae of the bark beetles Scolyt...
