Insects do not normally cause serious damage to forests unless their numbers increase, for some reason or another, to very high densities. The area of ecology that deals with changes in the density of organisms over time and that attempts to explain the causes of these changes is known as population dynamics. This chapter explores the concepts of population dynamics as they relate to forest insects, in order to better understand the causes of forest pest outbreaks.

The mathematical model adopted in this paper, introduces an explicit linkage between the beetle population dynamics and an age-structured forest population dynamics subject to tree harvesting. The formulation builds upon the approach in [ 5 ] by adding the explicit dependence of the carrying capacity of the beetle population on the age of trees.
