Abstract

Pheromone baited traps and trap trees attracted an aggregate of 29 scolytid species associated with white spruce in three localities in Alaska. Species diversity was higher in the Fairbanks (lat. 64°45′) area than in the Brooks Range (lat. 68°15′) or Kenai Peninsula (lat. 60°37′). Scolytids were found inhabiting all bark-producing areas of the tree from the roots to small branches with the highest density in the tree bole. The most abundant scolytids were Ips perturbatus (Eichhoff), Ips tridens tridens (Mannerheim), Polygraphus rufipennis (Kirby), Dryocoetes affaber (Mannerheim), Trypodendron lineatum (Olivier), and Scolytus piceae (Swaine).

Résumé

Des pièges appâtés de phéromone et des arbres-pièges ont attiré un ensemble de 29 espèces de scolytes associés à l'épinette blanche dans trois localités en Alaska. La diversité des espèces était plus grande dans la région de Fairbanks (latitude 64°45′) que dans la chaîne de Brooks (latitude 68°15′) ou la péninsule de Kenai (latitude 60°37′). Des scolytes ont été observés attaquant toutes les parties de l'arbre produisant de l'écorce allant des racines aux petites branches, le tronc étant la partie la plus attaquée. Les espèces les plus communes étaient Ips perturbatus. (Eichhoff), Ips tridens tridens (Mannerheim), Polygraphus rufipennis (Kirby), Dryocoetes affaber (Mannerheim), Trypodendron lineatum (Olivier) and Scolytus piceae (Swaine).
