Abstract

The systemic insecticides oxydemeton-methyl and acephate were injected at 10- and 15-cm spacings, and acephate and dimethoate were implanted at 10-cm spacing in Douglas fir, Pseudotsuga menziesii var. glauca (Beissn.) Franco, to improve seed yield. Nutrients were also injected at 15-cm spacing. All treatments except nutrients and dimethoate increased the yield of filled seeds when compared with the checks. The western spruce budworm, Choristoneura occidentalis Freeman, and spruce coneworm, Dioryctria reniculelloides Mutuura and Munroe, caused most of the damage to cones.

Résumé

On a injecté les insecticides systématiques oxydéméton-méthyl et acéphate à intervalles de 10 et 15 cm, et on a implanté de l'acéphate et du diméthoate à intervalles de 10 cm à du Douglas, Pseudotsuga menziesii var. glauca (Beissn.) Franco, afin d'en augmenter le rendement en graines. On a aussi injecté des nutriments à intervalles de 15 cm. Tous les traitements ont augmenté le rendement en graines remplies lorsque comparés aux témoins. La tordeuse occidentale de l'épinette, Choristoneura occidentalis Freeman, et la pyrale des cônes de l'épinette, Dioryctria reniculelloides Mutuura and Munroe, étaient principalement responsables des dommages aux cônes.
