Trypophloeus
Trypophloeus is a genus of bark beetles in the family Curculionidae, subfamily Scolytinae, containing approximately 12 species distributed across North America, Europe, and Asia. The genus is primarily associated with Salicaceae hosts, particularly Populus and Salix species. Trypophloeus populi has gained recent attention as the causative agent of sudden aspen decline in North America. Several species are significant forest pests, with T. klimeschi causing extensive damage to shelter forests in northwest China and T. binodulus affecting poplar plantations in Spain.
