LOCAL DISPERSAL OF MALE SPRUCE BUDWORM (LEPIDOPTERA: TORTRICIDAE) MOTHS DETERMINED BY MARK, RELEASE, AND RECAPTURE

  • C. J. Sanders (a1)

Abstract

Local dispersal and survival of male spruce budworm, Choristoneura fumiferana (Clem.), moths under field conditions was determined by mark, release, and recapture in pheromone-baited traps. Recapture rates and distance of recapture were dependent upon height of traps and proximity of traps to the release point, but over 65% of those recaptured were caught within 50 m. With traps 20 m apart, 30% of the recaptures were in traps farthest from the release point (50–70 m), a fact which suggests that male spruce budworm may disperse beyond this distance at low densities. Males were recaptured up to 7 days after release, and had a daily survival rate averaging 67%.

Par la méthode des captures, du marquage et des recaptures dans des pièges à phéromone, on a déterminé la dispersion locale et la survie de papillons mâles de la tordeuse des bourgeons de l'épinette, Choristoneura fumiferana (Clem.), dans la nature. Le taux et la distance de recapture ont été fonction de la hauteur des pièges et de leur distance du point de libération des papillons, mais 65% de ces derniers ont été recapturés à moins de 50 m. La distance entre les pièges était de 20 m, et 30% des recaptures ont été faites dans les pièges les plus éloignés du point de libération (50 à 70 m), ce qui porte à croire que les mâles peuvent se disperser au-delà de cette distance à faible densité. Certains mâles ont été recapturés jusqu'à sept jours après leur libération, et le taux de survie a été de 67% en moyenne.
