- Abstract
The article presents a study which investigates the impact of minimum winter temperatures on the population dynamics of Dendroctonus frontalis in the U.S. The study has employed a generalized approach to estimate whether minimum winter temperatures drives the pestilence of this beetle. Derived from the analysis of beetle abundance data from 1987 to 2005, it has showed that the minimum winter air temperature only explained 1.5% of the variance in rates of beetle populations. It indicated that generally it is a weak driver of population beetles population dynamics
