Abstract

Field experiments demonstrated that the western balsam bark beetle, Dryocoetes confusus, responded best to multiple-funnel traps baited with mixtures of (+)- and (−)-exo-brevicomin. (±)-exo-Brevicomin released at 0.8 mg per 24 h performed as well as or better than release rates of from 0.2 to 1.0 mg per 24 h in terms of the number of baited trees which were mass attacked (80%), average attack density, and average number of trees attacked within a 10-m radius of baited trees. Baiting more than one tree in a spot resulted in an intensification of attack on baited trees and increased the number of trees attacked within 10 m of each spot.

Résumé

Des Scolytes du sapin de l’ouest, Dryocoetes confusus, ont été mis en présence de pièges à plusieurs entrées, en nature, et ce sont les entrées garnies de mélanges de brévicomine-(+) et (−) qui les attiraient le plus. La libération du produit à raison de 0,8 mg par 24 h donne des résultats équivalents ou supérieurs à des taux de libération de 0,2 à 1,0 mg par 24 h, puisque c’est à ce taux que le nombre d’arbres garnis envahis par des masses d’insectes est le plus élevé (80%), que la densité moyenne des insectes envahisseurs est le plus grande et que le nombre moyen d’arbres attaqués dans un rayon de 10 m des arbres garnies est le plus élevé. En garnissant plus d’un arbre en un point, on peut augmenter la fréquence des attaques sur les arbres garnis et augmenter le nombre d’arbres attaqués dans un rayon de 10 m de chaque point.
