Abstract

Inundative release of Trichogramma brassicae Bezdenko for control of European corn borer was tested in experimental plots in 1991 and 1992 in southern Alberta, Canada, to determine its effectiveness as a potential method of control in sweet corn. The tests were conducted in 1-ha plots, in three different fields of irrigated sweet corn each year, at a release level of about 196 000 wasps per ha. The reduction in European corn borer damage in the release plots ranged from 85 to 87% in 1991 and from 45 to 95% in 1992. The reduction in damage was not significantly different in fields with 25 and 49 release points. General area degree-day accumulation for postdiapause development was not adequate to determine the timing of release for individual fields because European corn borer phenology varied among fields. Total moth catch in pheromone traps, however, was directly related to the number of plants damaged by European corn borer, and releases near the time of peak trap catch produced the greatest reduction in damage.

Résumé

La libération massive de Trichogramma brassicae Bezdenko a été expérimentée en 1991 et 1992 sur des grilles échantillons du sud de l’Alberta et son efficacité comme méthode de contrôle de la Pyrale du maïs a été mesurée dans des champs de maïs sucré. Les tests ont été faits chaque année dans des grilles de 1 ha, et environ 196 000 guêpes par ha ont été mises en liberté en trois champs irrigués de maïs sucré. La réduction des dommages causés par la pyrale dans les grilles expérimentales a été évaluée à 85–87% en 1991 et à 45–95% en 1992. La réduction des dommages n’était pas fonction du nombre de sites de relâchement et elle ne variait pas significativement, que le nombre de points de relâchement des guêpes ait été de 25 ou de 49. Le nombre de degrés-jours accumulés au cours du développement après la diapause dans une zone donnée ne pouvait pas servir à déterminer le moment optimal de libération dans un champ particulier parce que la phénologie de la pyrale variait d’un champ à l’autre. En revanche, le nombre total de papillons capturés dans des pièges à phéromone était directement relié au nombre de plants endommagés par la pyrale et la libération des guêpes au moment où les captures étaient maximales entraînait la réduction la plus importante des dommages.
