Evidence for regional variation in the thermal biology of Dendroctonus rufipennis (Kirby) (Coleoptera: Curculionidae, Scolytinae) in Colorado
Dendroctonus rufipennis (Kirby) (Coleoptera: Curculionidae, Scolytinae), the spruce beetle, is native to the forests of western North America where it is the primary cause of Engelmann spruce Picea engelmannii Parry ex Engelm. mortality. This study is an effort to further the knowledge of ecological conditions that affect D. rufipennis flight phenology, abundance, and fitness traits. Spruce beetle populations were monitored for two years at high elevation spruce forest sites; during this period of time 32,881 spruce beetles were captured, as well as significant quantities of off-target species. ...
