Pratylenchus alleni

Pratylenchus alleni is a migratory endoparasitic nematode, living inside of plant roots and feeding on parenchyma cells in the root cortex. P. alleni is an obligate biotroph, meaning it must have a living host in order to survive. Due to their incredibly broad host range, Pratylenchus species fall third in total economic impact, finishing just behind cyst nematodes (Heterodera & Globodera) and root knot nematodes (Meloidogyne). In Canada, it was isolated for the first time in 2011 in a soybean field.
