HOST EFFECTS ON FERTILITY AND REPRODUCTIVE SUCCESS OF DENDROCTONUS PONDEROSAE HOPKINS (COLEOPTERA: SCOLYTIDAE)

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 ...

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

Relative Suitability of Virginia Pine and Loblolly Pine as Host Species for Dendroctonus frontalis (Coleoptera: Scolytidae)

AKSTRACT Dcrcriloclo~~~r~s Jj-or&r/is Zim~nernr:tn is a major disturbance agent in Alnericnn pine forests, but attack prefcrcnccs for various host spt:cic:s, and their relative suitability for reproduction, are poorly knowi). We studied patterns of beetle attack and reproduction during an infestation of stands contairiing Virginia pine and lol~lolly pine. Nearly all Virginia pine were attacked ...

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...

Scientific Note An improved synthetic attractant for the mountain pine beetle, Dendroctonus ponderosae Hopkins (Coleoptera: Curculionidae: Scolytinae), in northeastern California

The mountain pine beetle, Dendroctonus ponderosae Hopkins 1902, is found in pine forests throughout the western U.S., north to northern British Columbia and Alberta, Canada and south to Mexico. It causes high levels of pine mortality throughout its range. Hosts include many species of Pinus (Pinaceae); in northern California, D. ponderosae is a pest of pine types dominated by P. ponderosa Dougl...
