Abstract

Four commercial sex attractant traps were evaluated for monitoring low density spruce budworm (Choristoneura fumiferana (Clem.)) populations. Factors considered were color, the number of male budworm caught, durability of traps and their ability to exclude non-target insects and debris. The Pherocon 1CP was superior to 3-M Brand Sectar 1 and XC-26; Pherocon 1C was least suitable. Interpretation of the numbers captured may be confounded by the fact that trapped males repel other males.

Résumé

L’auteur évalua l’efficacité de quatre pièges commerciaux munis d’attractifs sexuels pour suivre de près les faibles populations de la Tordeuse des bourgeons de l’Epinette (Choristoneura fumiferana (Clem.)). Les facteurs étudiés sont la couleur, le nombre des Tordeuses mâles piégées, la durabilité des pièges et leur capacité d’exclure les insectes non visés et les débris. Le Pherocon 1CP se révèle supérieur au 3-M Brand Sectar 1 et au XC-26; le Pherocon 1C se révèle le moins approprié. L’interprétation du nombre de captures peut être faussée par le fait que les mâles capturés repoussent d’autres mâles.
