Résumé / Abstract

Esteya vermicola gen. et sp. nov. isolated from infected pinewood nematodes, Bursaphelenchus xylophilus, is described and illustrated. The new species is characterized by the production of two types of conidiophores, conidiogenous cells, and conidia. The first type of conidiophore is subhyaline to greyish green, flask-shaped, apex tapering at the apex into a thin neck, sometimes crooked; the conidiogenous cells are integrated, phialidic, rarely percurrent; the conidia are hyaline, one-celled, lunate, concave, containing an endospore-like apparatus, adhesive. The second type of conidiophore is subhyaline to greyish green, cylindrical, subulate, septate, the base somewhat swollen; conidiogenous cells integrated, phialidic; conidia hyaline, one-celled, bacilloid, often forming an aggregate droplet at the apex, non-adhesive. Esteya vermicola exhibits high infectivity towards the pinewood nematode, and the potential for its development as a biocontrol agent against the pinewood nematode is briefly discussed.
