متن کاملRegeneration Methods to Reduce Pine Weevil Damage to Conifer Seedlings
Petersson, M. 2004. Regeneration methods to reduce pine weevil damage to conifer seedlings. ISSN: 1401-6230, ISBN: 91 576 6714 4 Damage caused by the adult pine weevil Hylobius abietis (L.) (Coleoptera, Curculionidae) can be a major problem when regenerating with conifer seedlings in large parts of Europe. Weevils feeding on the stem bark of newly planted seedlings often cause high mortality in...
متن کاملPheromone interruption of pine engraver, Ips pini, by pheromones of mountain pine beetle, Dendroctonusponderosae (Coleoptera: Scolytidae)
The effect of pheromones of Hopkins on the at t ract ion of Ips pini (Say) to its pheromone, ipsdienol, was investigated in stands of lodgepole pine. The mixture of cisand trans-verbenol significantly reduced catches of 1. pini in t raps baited with ipsdienol at three locations in British Columbia. exo-Brevicomin had no effect on catches of f. pini, irrespective of the enantiomeric composition ...
متن کاملcis-Verbenol: An aggregation pheromone for the mountain pine beetle, Dendroctonlcs ponderosae Hopkins (Coleoptera: Scolytidae)
c-is-Verbenol increased catches of male mountain pine beetles, Dendroctonus ponderosae Hopkins, to multiple-funnel traps baited with myrcene and em-brevicomin. cis-Verbenol had no effect on the response of males to traps baited with myrcene, exo-brevicomin and tl-ans-verbenol. In contrast, cis-verbenoi inct-eased catches of female D. ponderosae to semiochemical-baited traps irrespective of the ...
متن کاملInterspecific Variation in Host-Finding Cues of Parasitoids of the Southern Pine Beetle (Coleoptera: Scolytidae)’
J. Entomol. Sci. 38(4): 631-643 (October 2003) Abstract Experiments were performed with host-associated olfactory attractants of the larval parasitoids of the southern pine beetle, Dendrocfonus frontal& Zimmermann, to elucidate both their biological origin and their chemical composition. Sticky-screen traps were erected in an active D. frontalis infestation and baited with parts of D. front&s-i...
