Blue Stain

A new basidiomycete, Entomocorticium dendroctoni Whitn., Band. & Oberw., gen. et sp. nov., is described and illustrated. This cryptic fungus intermingles with blue stain fungi and produces abundant essentially sessile basidiospores in the galleries and pupal chambers of the mountain pine bark beetle (Dendroctonus ponderosae Hopkins Coleoptera: Scolytidae) in lodgepole pine (Pinus contorta Dougl. var. latifolia Engelm.). The insect apparently disseminates the fungus. Experimentally, young partially insectary reared adult beetles fed E. dendroctoni produced 19% more eggs than beetles fed the blue stain fungi.

Overall Ratio

Five replicates of paired forest blocks containing lodgepole pine, Pinus contorts var. latifolia Engelm., infested by the mountain pine beetle, Dendroctonus ponderosae Hopkins, were chosen in the spring of 1982 in various interior British Columbia locations. Within the experimental block of each pair, one lodgepole pine every 50 m (4 trees/ha) was baited with the attractive semiochemicals myrcene, trans-verbenol and exo-brevicomin. The baiting program caused the attack in 1982 to be concentrated in and around the baited trees, whereas it was more dispersed in the control blocks. The overall ratio of 1982: 1981 attacked trees was 2.5 in the baited blocks and 1.8 in the controls, suggesting that dispersal of beetles out of the baited blocks was inhibited. Baiting of trees with semiochemicals is recommended to contain infestations within prescribed boundaries when sanitation-salvage logging cannot be completed prior to mid-summer flight of emergent brood beetles.

Common Parasite

AbstractThe mountain pine beetle, Dendroctonus ponderosae, and 68 associated insect species were reared from infested sugar pine, Pinus lambertiana. Portions of three infested trees were sectioned by height and the insects emerging from each were identified and recorded. In one tree the number of woodpecker strikes also was noted. The tops of two of the three trees were infested by another bark beetle, Pityophthorus confertus, and from these same two trees the most common parasite obtained was Macromesus americanus.

AbstractThe mountain pine beetleDendroctonus ponderosaeHopkins (Coleoptera: Curculionidae) kills its hosts by attackingen masseand overwhelming tree defences. Young adult beetles completing development under the bark may have the opportunity to mate with siblings or with brood from adjacent galleries prior to emerging from the natal host tree. We investigated the incidence of preemergence mating among female beetles at two locations in the recently expanded range of the insect in northern Alberta, Canada. Female beetles emerging from under the bark late in the emergence period were more likely to be mated upon emergence than beetles that emerged earlier. Delaying emergence of brood adults once they were at the teneral adult stage had little effect on the incidence of preemergence mating. The frequency of preemergence mating varied from 3–12% among female beetles. This is higher than the 1–2% reported in other studies within the historic range of the mountain pine beetle. Reasons for these differences are discussed.

Number Of Males

Within an egg gallery of the mountain pine beetle (Dendroctonus ponderosae Hopk.) only one male is found with one female even though the virgin female or its frass may have been equally attractive to more than one male. To ascertain how the number of males joining a female is determined, a series of 10 lodgepole pine rearing slabs and 10 observational plates (Reid 1962) were infested with virgin mountain pine beetle females. The females were allowed 1 day to become established prior to the experiments. On the second day one virgin male was placed in each gallery. The next day a second was placed near the entrance to the gallery and its behavior was noted, as well as that of the first male.
