摘要: Temperature is a critical single factor influencing insect population dynamics, and foundational for improving our understanding of the phenology invasive species adapting to new agroecosystems or in process range expansion. An age-stage, two-sex life table was therefore developed analyze fundamental demographic features such as development, survival, reproduction Minnesota-acclimated brown marmorated stink bug (Halyomorpha halys), north central USA. All salient history parameters were estimated better understand growth potential H. halys at current limit its northern North America. We examined effect selected constant temperatures on immature development survival (15-39 °C), adult longevity (17-36 °C) laboratory. The Minnesota faster survived higher rates relative that had previously established Pennsylvania, Mean generation time minimized 30 °C, while fecundity maximized 27 23 respectively. Given these findings, we assessed temperature intrinsic rate increase (rm), parameter integrates effects reproduction.
