Abstract

No correlation was found between the size of male spruce budworm (Choristoneura fumiferana [Clem.]) moths and the duration of their flight in a sustained-flight wind tunnel. The numbers of male moths caught in traps baited with virgin female spruce budworm moths increased as the size of the females increased, but the relationship was significant in only one of eight experiments. Infection with the microsporidium Nosema fumiferanae (Thomson) resulted in smaller insects, but there were no significant relationships between the incidence of infection and male flight duration or female attractiveness.

Résumé

Aucune corrélation n’a pu être établie entre la taille des papillons mâles de la tordeuse des bourgeons de l’épinette (Choristoneura fumiferana [Clem.]) et la durée de leur vol dans un tunnel de vol. Le nombre de papillons mâles capturés dans des pièges appâtés avec papillons femelles vierges de la tordeuse des bourgeons de l’épinette a augmenté à mesure que s’accroissait la taille des femelles, mais cette relation n’était significative qu’au cours d’une seule des huit expériences. L’infection par la microsporidie Nosema fumiferana (Thomson) s’est traduite par une réduction de la taille des insectes, mais aucune relation significative n’a pu être établie entre l’incidence de l’infection et la durée de vol des mâles ou l’attractivité des femelles.
