Interaction of pre-attack and induced monoterpene concentrations in host conifer defense against bark beetle-fungal complexes

Two pine species (Pinus resinosa, P. banksiana) responded to inoculation with fungi carried by bark beetles by rapidly increasing monoterpene concentrations at the entry site. Changes in total monoterpenes were more pronounced than changes in proportionate compositions. The extent and rate of host response was affected by fungal species, the viability of… CONTINUE READING
