Abstract

Frontalin, a synthetic pheromone, induces attacks by the spruce beetle (Dendroctonus rufipennis) on baited standing trees, in which most broods fail. The impact of baiting 100 randomly chosen trees was determined by estimating the beetle population in a 766-ha spruce forest. Attack density in infested bark was similar for wind-thrown and baited trees; however, 95% of attacks occurred on the former, which were more numerous and had greater attacked surface areas. In this forest, it is estimated that 34 frontalin-baited trees would have been required for each windfall to trap 90% of the beetle population.

Résumé

La frontaline, phéromone synthétique, attire Dendroctonus rufipennis vers des arbres debouts qui en ont été appatés et qui en outre font presque toujours avorter la progéniture de l’insecte. Les auteurs déterminèrent l’effet d’appater 100 arbres choisis au hasard, ce en estimant la population de Dendroctones dans une forêt d’Epinettes contenant 766 hectares. La force de l’attaque dans l’écorce infestée se révéla semblable dans les arbres chablis et les arbres debouts appatés; cependant 90% des attaques se produisirent dans les chablis qui étaient plus nombreux et dont les surfaces attaquées étaient plus grandes. Dans cette forêt, il faudrait 34 arbres debouts et appatés de frontaline pour chaque arbre chablis pour réussir à trapper 90% de la population de Dendroctones.
