Abstract

Genetic variation among western spruce budworms from 14 sites of high-density infestation in central Idaho and western Montana was examined using electrophoresis. Relationships were assessed through cluster analysis of genetic distance values and by study of shared rare alleles. Three genetically similar groupings appeared among budworms over the 14 sites. The genetic data and analysis of historical records of outbreaks over the area indicate that dispersal may play a significant role in the spread of some infestations.

Résumé

La variation génétique entre populations de tordeuse occidentale de l'épinette provenant de 14 sites d'infestation à haute densité localisés dans l'Idaho central et le Montana occidental, a été étudiée par électrophorèse. Les relations ont été évaluées en soumettant les valeurs de distance génétique à l'analyse de dispersion des groupes, et en étudiant les allèles rares communs. Trois regroupements génétiquement semblables sont apparus sur l'ensemble des 14 sites. Les données génétiques et l'analyse de l'historique des épidémies dans cette région indiquent que la dispersion joue probablement un rôle important dans le développement des infestations.
