文摘
- •
Highest root ethanol concentrations are in a narrow zone outside infected xylem.
- •
A model using ethanol concentrations detects trees with P. sulphurascens infection.
- •
Ethanol analysis provides no advantage over root cores for identifying hazard trees.
- •
Ethanol with host monoterpenes is proposed as the primary attractant for bark beetles.
