DOIAbstract
Megaplatypus mutatus (Chapuis) (Coleoptera, Platypodidae) is an ambrosia beetle native to South America. It builds internal galleries that weaken the tree trunks, causing them severe stem breakage and mortality in commercial poplar plantations. The host selection by male M. mutatus has previously been correlated with the increasing diameter. This work explores the possibility that differential susceptibility of individual plants to M. mutatus could be associated with volatiles emitted. The comparison of the VOCs profiles of attacked and nonattacked P. x canadensis “Conti” 12 during M. mutatus flying season showed both qualitative and quantitative differences. The attacked plants, but not the nonattacked ones, showed the following compounds:...
