Abstract

An established population of the exotic woodwasp Sirex noctilio Fabricius (Hymenoptera: Siricidae) was first detected in North America in 2004. In order to develop survey guidelines for the detection of this major pest of Pinus Linnaeus species in the Southern Hemisphere, we examined 231 Pinus sylvestris biweekly to establish the timing and spatial distribution of resinosis symptoms of attack, and the timing of subsequent tree mortality. Fresh resin appeared between mid-July and late August, and on 70% of infested trees was observed on the mid bole. The occurrence of tree death varied between sites, from 2 weeks after the first detection of resinosis in one site to several months in seven other sites. Findings from our study provide key information to improve detection of S. noctilio and predict its impact on forest stands in its new range in northeastern North America.

Résumé

On a observé pour la première fois en 2004 une population bien établie du sirex exotique Sirex noctilio Fabricius (Hymenoptera: Siricidae) en Amérique du Nord. Afin de rédiger des notes d'orientation pour la détection de cet important ravageur des espèces de Pinus Linnaeus dans l'Hémisphère austral, nous avons examiné à toutes les deux semaines 231 P. sylvestris afin d’établir le calendrier et la répartition spatiale des symptômes de résinose lors de l'attaque et le moment de la mortalité subséquente des arbres. De la résine fraîche apparaît entre la mi-juillet et la fin d'août et se retrouve, chez 70% des arbres infestés, à la mi-hauteur du tronc. Le moment de la mort des arbres varie d'un site à l'autre, de deux semaines après la première détection de résinose dans un site à plusieurs mois dans sept autres sites. Les résultats de notre étude fournissent des informations essentielles pour améliorer la détection de S. noctilio et pour prédire son impact sur les peuplements forestiers dans sa nouvelle aire de répartition dans le nord-est de l'Amérique du Nord.
