Abstract

The relationship between the phenological development of the spruce budmoth (SBM), Zeiraphera canadensis, and that of its primary host, white spruce, was studied in New Brunswick using descriptive indices for both insect and host development. Larval emergence of SBM was synchronized with bud burst of white spruce, the species on which most eggs are laid. Subsequent SBM larval development can be estimated through reference to the development index for white spruce. For black, Norway, and red spruce, initial bud burst occurred approximately 15, 3, and 15 days, respectively, later than white spruce and this asynchrony is probably one of the reasons why the SBM is not an important pest on these tree species.

Résumé

La relation phénologique entre le développement de la tordeuse de l’épinette, Zeiraphera canadensis, et celui de son hôte primaire, l’épinette blanche, a été étudiée dans le nord du Nouveau-Brunswick à l’aide d’indices numériques. L’utilisation des indices a permis de démontrer que l’émergence des larves de la tordeuse de l’épinette était synchronisée avec l’éclosion des bourgeons de l’épinette blanche, l’espèce sur laquelle la majorité des oeufs étaient pondus. A l’aide des indices, on peut également prédire le stage de développement des larves de la tordeuse, en déterminant d’abord l’indice de développement de l’épinette blanche. L’éclosion des bourgeons végétatifs de l’épinette noire, de l’épinette de Norvège et de l’épinette rouge, est survenue approximativement 15, 3 et 15 jours respectivement, plus tard que celle de l’épinette blanche. Il est probable que ce retard puisse expliquer partiellement l’absence de dégâts de la tordeuse de l’épinette sur ces 3 espèces d’épinettes.
