Abstract

The angiosperm bark volatile, conophthorin, was tested at release rates of 3.0 and 0.3 mg/24 h against the Douglas-fir beetle, Dendroctonus pseudotsugae Hopkins, the spruce beetle, Dendroctonus rufipennis (Kirby), the pine engraver, Ips pint (Say), and the western balsam bark beetle, Dryocoetes confusus Swaine (all Coleoptera: Scolytidae). The responses of D. pseudotsugae, I. pini, and (in one of two experiments) female D. confusus to attractant-baited traps were disrupted by conophthorin in a dose-dependent manner. Dendroctonus rufipennis was not disrupted by conophthorin. Our results extend the repellent bioactivity of conophthorin to Ips DeGeer spp. and confirm earlier experiments with D. pseudotsugae. Conophthorin may have some utility in protecting susceptible timber from bark beetle attack.

Résumé

La conophtorine, une substance volatile de l’écorce des angiospermes, a été testée à des taux d’émission de 3,0 et de 0,3 mg/24 h chez quatre espèces de scolytes, le Dendroctone du Douglas, Dendroctonus pseudotsugae Hopkins, le Dendroctone de l’épinette, Dendroctonus rufipennis (Kirby), le Scolyte du pin, Ips pini (Say) et le Scolyte du sapin de l’ouest, Dryocoetes confusus Swaine. Les réactions de D. pseudotsugae et d’I. pini (au cours de l’une de deux expériences) et des femelles de D. confusus à des pièges garnis d’une substance attirante ont été perturbées par la conophthorine et cela en fonction de la dose. Dendroctonus rufipennis ne réagit pas à la conophthorine. Nos résultats démontrent que l’effet repoussant de la conophthorine agit aussi sur Ips DeGeer et confirment les résultats d’expériences antérieures sur D. pseudotsugae. La conophthorine peut s’avérer utile pour protéger le bois coupé des invasions de scolytes.
