ous ecological catastrophe and economic losses to the pine forest industry. The pinewood nematode (PWN), Bursaphelenchus xylophilus, is the causal agent and is transmitted by vector beetles (Futai, 2013). The beetle Monochamus alternatus and M. galloprovincialis are the insect vectors that transmit the PWN (Akbulut & Stamps, 2012; Sousa et al., 2002). PWNs enter into the healthy host pine tree via feeding wounds of young immature beetles (Mamiya, 1983). The PWNs in the host pine tree feed on living epithelial cells and distribute throughout the tree via resin canals (Wang et al., 2011), resulting in vascular dysfunction and rapid wilt of host trees.As the first reported nematophagous fungi against PWN, Esteya vermicola has been tested to control PWD (Liou et al., 1999;Wang et al., 2011Wang et al., , 2018. Two types of conidiogenous cell and conidia (lunate and bacilloid conidia) in solid culture and blastospore in liquid culture are produced by the fungal hyphae (Wang et al., 2008). Among
