Abstract

The Douglas-fir beetle (Dendroctonus pseudotsugae) antiaggregation pheromone, 3-methylcyclohex-2-en-1-one (MCH), was applied to stands at high risk for infestation. The MCH was applied in a bubble capsule formulation to plots ranging from 2.1 to 2.6 ha in size at rates of 45–76 g/ha. Catches of Douglas-fir beetles in attractant-baited Lindgren funnel traps located at the plot centers were significantly lower on MCH-treated plots compared with untreated plots. In contrast, catches of the most abundant predator, Thanasimus undatulus (Say), were unaffected by the MCH treatment. The percentage of Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] trees ≥20 cm dbh that were mass attacked was significantly lower on treated plots (0.2%) compared with untreated plots (8.5%). MCH alone was effective in reducing the probability of Douglas-fir beetle infestations occurring in high risk stands.

Résumé

La phéromone anti-rassemblements du Dendroctone du Douglas (Dendroctonus pseudotsugae), la méthyl-3 cyclohexène-2 one-1 (MCH) a été utilisée dans des forêts très sensibles aux infestations. Le produit a été appliqué dans une capsule en bulle sur des parcelles de terrain de 2,1 à 2,6 ha de surface à raison de 45–76 g/ha. Les échantillons de coléoptères recueillis dans des pièges de Lindgren appâtés situés au centre ses parcelles, étaient significativement plus faibles dans les parcelles traitées que dans les parcelles non traitées. En revanche, le traitement au MCH n’a pas affecté le nombre de captures du prédateur le plus abondant, Thanasimus undatulus (Say). Le pourcentage d’arbres infestés [Pseudotsuga menziesii (Mirb.) Franco] de plus de 20 cm de diamètre à hauteur de poitrine a été significativement plus faible dans les parcelles traitées (0,2%) que dans les parcelles non traitées (8,5%). La phéromone seule peut donc réduire efficacement la probabilité d’infestation par le Dendroctone du Douglas dans les forêts très sensibles.
