Diversity and Distribution of Xylophagous Beetles from <i>Pinus thunbergii</i> Parl. and <i>Pinus massoniana</i> Lamb. Infected by Pine Wood Nematode
The vectors of pinewood nematode of <i>Bursaphelenchus xylophilus</i> (Steiner & Bührer, 1934) are mainly known as xylophagous beetles. Understanding the composition and distribution of these xylophagous beetles in host pine trees infected by PWN is critical to control the spread of...
