Special delivery: A hardwood‐killing bark beetle vectors its unusual symbiote among host trees

open access: yesEcosphere, Volume 16, Issue 5, May 2025.
Abstract In mutualistic symbioses with fungi, herbivorous insects such as bark beetles (Coleoptera: Curculionidae: Scolytinae) gain access to resources that are unavailable in the absence of fungal mutualists, while fungi benefit from insect‐vectored dispersal. The most well‐studied mutualists of tree‐killing bark beetles in conifer systems are certain
