Abstract

We tested the prediction that larvae of the fir coneworm, Dioryctria abietivorella (Groté), preferentially exploit cones previously damaged by cone maggots, Strobilomyia spp. In most years sampled, fir coneworm attacked a significantly greater proportion of maggot-damaged than healthy cones of both white spruce and black spruce. The ecological implications for pest management are briefly discussed.

Résumé

Nous avons éprouvé l’hypothèse selon laquelle les larves de la Pyrale des cônes du pin, Dioryctria abietivorella (Groté), préfèrent les cônes préalablement endommagés par les mouches granivores Strobilomyia spp. La plupart des années, les larves de la pyrale se sont attaquées à des proportions significativement plus élevées de cônes déjà endommagés par les mouches granivores qu’aux cônes sains des épinettes blanches ou noires. La portée écologique de ce phénomène dans la lutte biologique contre les parasites fait l’objet d’une brève discussion.
