Abstract Rising atmospheric carbon dioxide (CO 2 ) concentrations are a major driver of climate change, posing significant challenge to global ecosystem functions. This is compounded by the potential effects elevated CO on forest pest insects like eastern spruce budworm (Lepidoptera: Tortricidae), mortality agent in Canadian boreal forests. To better understand these impacts, this study investigates how (1000 ppm) and ambient (469 affect development across different life stages. In vitro experiments revealed that budworms exposed concentration exhibited accelerated development, with increased larval weight gain from third sixth instars, faster pupation adult emergence, earlier oviposition compared those condition. However, led reduced realised fecundity. These findings highlight direct impact biology, important implications for its role ecosystems under change.
