Repellency and Toxicity of Conophthorus ponderosae Hopkins (Coleoptera: Scolytidae) by the Host Monoterpene Myrcene

cis-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 ...

Comparison of a-pinene and myrcene on attraction of mountain pine beetle, Dendroctonus ponderosae (Coleoptera: Scolytidae) to pheromones in stancls of western white pine

Multiple-funnel traps baited with exo-brevicomin and a mixture of cisand transverbenol were used to test the relative attractiveness #If myrcene and (-)-a-pinene to the mountain pine beetle, Dendroctonus ponderosae Hopkins, in a s tand of western white pine, Pinus mont icola Doug]. Traps baited with myrcene caught significantly more D. ponderosae than traps baited with (-)-a-pinene, irrespectiv...

First Nebraska State Collection Record of the Mountian Pine Beetle, Dendroctonus Ponderosae Hopkins (Coleoptera: Curculionidae: Scolytinae)

Dose-dependent and Species-specific Responses of Pine Bark Beetles (coleoptera: Scolytidae) to Monoterpenes in Association with Pheromones

The Canadian Entomologist 132: 183 195 (2000) Monoterpenes affected the attraction of three sympatric species of bark beetles (Coleoptera: Scolytidae) to pheromone-baited multiple-funnel traps in stands of lodgepole pine. Catches of Ips pini (Say) in traps baited with its pheromone, ipsdienol, were directly related to the release rates of 3-carene, pphellandrene, and ppinene. Catches of Dendroc...

Isolation and characterization of 16 microsatellite loci in the mountain pine beetle, Dendroctonus ponderosae Hopkins (Coleoptera: Curculionidae: Scolytinae).

We isolated 16 polymorphic microsatellite loci in the mountain pine beetle (Dendroctonus ponderosae Hopkins) and developed conditions for amplifying these markers in four multiplex reactions. Three to 14 alleles were detected per locus across two sampled populations. Observed and expected heterozygosities ranged from 0.000 to 0.902 and from 0.100 to 0.830, respectively. Three loci deviated from...
