Abstract

In field studies conducted to improve trapping programs for the white pine cone beetle, Conophthorus coniperda (Schwarz), a twig beetle, Pityophthorus puberulus (LeConte), a common associate of eastern white pine, Pinus strobus L. (Pinaceae), in seed orchards, was also captured. In these experiments, P. puberulus was attracted to traps containing the sex pheromone pityol with or without the monoterpenes (−)-α-pinene and (−)-β-pinene, but attraction to traps was inhibited when S-(−)-limonene was present. We speculate that limonene may play an important role in host recognition and suitability, by indicating a resource suitable for C. coniperda but unsuitable for P. puberulus.

Résumé

Des études de terrain menées pour améliorer les programmes de piégeage du scolyte des cônes du pin blanc, Conophthorus coniperda (Schwarz) ont permis de récolter aussi un scolyte des rameaux, Pityophthorus puberulus (LeConte), un insecte couramment associé aux pins blancs, Pinus strobus L. (Pinaceae), dans les pépinières à graines. Dans ces expériences, P. puberulus était attiré par les pièges appâtés avec la phéromone pityol avec ou sans les monoterpènes (-)-α-pinène et (-)-β-pinène; l'attraction des pièges est cependant inhibée par la présence de S-(-)limonène. Nous pensons que la limonène joue peut-être un rôle important dans la reconnaissance des hôtes et leur convenance, en identifiant les ressources appropriées à C. coniperda, mais non à P. puberulus.
