Pine Beetle

The pine engraver, Ips pini (Say), breeds in the phloem tissue of dead, dying, or downed pines, occasionally attacking standing live trees when populations build up to significant levels following logging activities or infestations by the mountain pine beetle, Dendroctonus ponderosae Hopkins (Furniss and Carolin 1980). In British Columbia, I. pini uses ipsdienol as an aggregation pheromone to facilitate large aggregations of mated beetles and breeding galleries (Miller et al. 1996). The aggregation pheromones, exo-brevicomin and cis- and trans-verbenol, used by D. ponderosae (Borden et al. 1987; Miller and Lafontaine 1991) interrupt attraction of I. pini to ipsdienol (Miller 1991). Another semiochemical, frontalin, is used by D. ponderosae as a multifunctional pheromone (Borden et al. 1987), enhancing attraction of beetles at low release rates and interrupting attraction at high release rates. I tested the effect of frontalin, over a broad range of release rates, on the attraction of I. pini to ipsdienol-baited traps.

Cross Attraction

AbstractThe pine engraver, Ips pini Say, and Pityogenes knechteli Swaine often co-exist in lodgepole pine, Pinus contoita var. latifolia Engelmann. We tested the hypotheses that P. knechteli produces an attractive pheromone and that the attraction of P. knechteli and I. pint to conspecifics is inhibited by the presence of the other species. Pityogenes knechteli males and females were attracted to bolts infested with conspecific males and to bolts infested with I. pini males; however, there was no significant cross-attraction of I. pini males or females to bolts infested with P. knechteli males. Attraction of P. knechteli and I. pint males and females to bolts infested with conspecific males was not inhibited in the presence of bolts infested with males of the other bark beetle species. Pityogenes knechteli has no potential for competitive displacement of I. pini but may enhance the adverse effect of I. pini on the mountain pine beetle, Dendroctonus ponderosae Hopkins.

We conducted seven experiments in stands of mature lodgepole pine in southern British Columbia to elucidate the role of host volatiles in the semiochemical ecology of the pine engraver, Ips pini (Say) (Coleoptera: Scolytidae), with particular reference to the behavioral responses of predators and competing species of bark beetles. Our results demonstrated that the attraction of Ips pini and the bark beetle predators Lasconotus complex LeConte (Colydiidae), Thanasimus undatulus (Say) (Cleridae) and a Corticeus sp. (Tenebrionidae) were increased by 3-carene. In contrast, attraction of the bark beetle Pityogenes knechteli Swaine (Scolytidae) to ipsdienol was interrupted by 3-carene and α-pinene. Attraction of L. complex to ipsdienol was increased by γ-terpinene, a compound attractive to the mountain pine beetle, Dendroctonus ponderosae Hopkins (Scolytidae). Terpinolene interrupted the attraction of I. pini to ipsdienol.

Lindgren multiple-funnel traps were used to evaluate the response of the pine engraver, Ips pini (Say), to the pheromones lanierone and ipsdienol, in Wisconsin and in southern Appalachia (western North Carolina and northern Georgia). As in Wisconsin, the attraction of I. pini to ipsdienol-baited traps in southern Appalachia was strongly synergised by lanierone. In Wisconsin, I. pini demonstrated a strong dose-response to both lanierone and ipsdienol, preferring traps releasing lanierone and ipsdienol at the highest rates. Ips pini in northern Georgia exhibited dose response to ipsdienol, preferring traps with lures releasing ipsdienol at the highest rate, but little in the way of a dose response to lanierone across the range of release rates tested. In Georgia, the sympatric species I. avulsus preferred traps with lures releasing ipsdienol and lanierone at the highest rates.

Operational Potential

The capture of pine engravers, Ipspini (Say), in ipdienol-baited, multiple-funnel traps in British Columbia was significantly reduced when devices releasing ipsenol or verbenone were placed in the traps. These results suggest that ipsenol and verbenone are synomones released by Ipslatidens (LeC.) and the mountain pine beetle, Dendroctonusponderosae Hopk., respectively. When verbenone and ipsenol were released together from five stations 2 m apart on felled trees, at 50 and 1.5 mg per day per tree, respectively, there was a 66.7% reduction in the number of logs attacked and a 98.8% reduction in attack density. The same treatment caused a 74.1% reduction in attack density on standing trees surrounded by a 4 × 4 grid of 16 release devices at 5- m centres. The antiaggregant composition of verbenone plus ipsenol has considerable operational potential for use in precommercial thinnings and in areas where standing pines are of high value; e.g., in rural subdivisions, shelterbelts, and recreational forests.

Needle Blight

BC’s forests have already faced two simultaneous, globally significant, epidemics linked to climate change; the Dothistroma needle blight epidemic in NW BC and the massive mountain pine beetle epidemic throughout the BC Interior. Building on these experiences, we have compiled our best estimates of how we believe other forest health agents may behave as climate change continues to influence our forests. We have drawn on literature from around the world but have focused on the situation in BC. We have made management recommendations based on what we have seen so far and what we expect to come.Key words: climate change, forest health, forest insects, forest pathogens, forest management, British Columbia

Recent impacts from the Mountain Pine Beetle epidemic, the lack of available timber in areas of lower elevation, and the reduction in back-country timber has pushed forest operations into publicly significant and visible landscapes. When these become the stage for operations they can be a source of public backlash. These kinds of landscapes are carefully protected by governments, yet, this protection may reduce timber availability. We have developed a new GIS-based tool to aid planners in designing harvests in these areas. Our tool is applied to three case studies in British Columbia to showcase how it can reduce planning time, increase timber availability and limit the negative visible effects of operations.
