Description: Population genetic structure studies made in genus Dendroctonus have been conducted from the perspectives of allopatric and sympatric models. In the first case, host effect and historical contingency were not recognized as a source of variation, while the later considered the host itself as a source of reproductive isolation. Nevertheless, both models show that genus Dendroctonus has the highest values of genetic variation among Scolytidae (Anderson and others 1979; Anderson and others 1983; Higby and Stock 1982; Langor and Spence 1991; Namkoong and others 1979; Roberds and others 1987; Stock and Guenther 1979; Stock and others 1979; Sturgeon and Mitton 1986; Zuñiga and others, in press). In this sense, few studies have been performed dealing with genetic population differences in D. pseudotsugae. For instance, through the use of Isozymes produced by 13 gene loci, Stock and others (1979) found a pattern characteristic of populations differentiated to, or beyond, the race or subspecies level between Idaho and Oregon populations. This was a consistent result in later works (Bentz and Stock 1986). However, none of these works performed a population genetic structure analysis.
