Megaplatypusmutatus is a SouthAmerican ambrosia beetle that affects poplar plantations, especially inArgentina and Europe. It attacks only standing live trees, boring long tunnelsacross the xylem and causing stem breakage in commercial poplar (Populus)plantations. In agriculture, fungal VOCs havebeen used as part of biological control strategies to prevent the growth ofplant pathogens and for control of insects formulated in lures or traps, andcould be a sustainable alternative to synthetic insecticides.Many fungal species related to M. mutatus wereisolated and identified from its natural environment.2-methyl-1-butanol,3-methyl-1-butanol, 2-phenyl ethanol and 2-undecanone were frequently presentin VOCs from fungal colonies from galleries, exoskeleton and hindgut of M.mutatus.
