The weevil was. Lodgepole pine forests are being heavily impacted by the ongoing mountain pine beetle epidemic From British Columbia to Colorado, forests are experi-encing high mortality of lodgepole pine trees from attack by mountain pine beetles.
An insect epidemic with multiple outbreaks at this scale has not been observedCited by: (Malajczuk et al. ), and studies have quantified forage production in mature, thinned ponderosa pine (P. ponderosa) stands (JamesonSeverson and Uresk ).
Lodgepole pine is a commonly planted conifer in forest plantations in the southern and central interior of British Columbia, : Percy James Folkard.
Introduction. Mature lodgepole pine (Pinus contorta var. latifolia Dougl ex. Loudon) stands are being attacked by mountain pine beetle (MPB) (Dendroctonus ponderosae Hopk.) throughout interior British Columbia (Safranyik and Wilson, ).A widespread and intensive salvage logging operation is underway but not all stands can or should be salvaged (Lindenmayer et Cited by: In other studies, where verbenone was applied to lodgepole pine for 1 year along with baits to ensure high MPB densities, mass attack percentages for bait alone versus bait plus verbenone.
Research programs to date in British Columbia on the biology, damage and control of the white pine weevil, Pissodes strobi, a pest of spruce, Picea spp. and pine, Pinus spp., are reviewed.
Rates of asymbiotic nitrogen fixation in woody debris, forest floor and mineral soils were investigated in stem-only harvested and wildfire-killed lodgepole pine (Pinus contorta ssp. latifolia Engelm. ex S. Wats.) stands in the central interior of British Columbia using an acetylene reduction assay.
The long-term contribution of those nitrogen fixation processes to site. Weevils have 4 life stages; adults, eggs, larvae and pupae. Weevils are primarily nocturnal, feeding in the evening and night and seek cover during the warmer days in the soil, or in shady plant foliage.
There are larval instars. Weevils spend about 10 months in the soil as larvae and pupae, where they are well protected. British Columbia (BC), Canada is experiencing a severe mountain pine beetle (MPB) (Dendroctonus ponderosae) epidemic extending over an area ofkm2. The widespread mortality of lodgepole pine (Pinus contorta var.
latifolia) caused by the beetle has significant implications for BC's timber supply and Canada's carbon (C) budget. Principal Hosts: Lodgepole pine.
Economic Importance: Infestation of saplings by P. terminalis results in forking and heavy branching. This leads to a non-merchantable stand. This insect is of concern to foresters in the interior since it thrives on the.
British Columbia's comprehensive provenance testing program for lodgepole pine provided an ideal test for the focal point seed zone approach.
The lodgepole pine provenance testing program, established by Keith Illingworth inincludes sources of lodgepole pine grown at 60 locations in 12 regions of the province.
British Columbia By ist and René I. Alfaro Turra) and Scots pine (P. sylvestris L.) are also attacked. No records of attack exist for western white pine (P.

British Columbia, Yukon. This weevil is found throughout much of western North America from Manitoba to British Columbia and from the Northwest Territories to Colorado and California. In British Columbia, it is most common in interior regions south of 56 0 latitude.

Abstract. Adults of the lodgepole terminal weevil, Pissodes terininalis Hopping, and 20 of the 30 “species” named orrecognized by Hopkins were reared out from host-conifer material positively identified by the donors.

Studies conducted by Kornelia Lewis, Yousry El-Kassaby and René Alfaro disclosed that weevils can live more than one year and are able to lay fertile eggs in the second season without mating again.
Females were able to store sperm from several males through the overwintering period. Larvae of the pine beauty moth Panolis flammae (Denis & Schiffermuller) were reared in sleeve cages on five different seed origins (provenances) of pole stage Pinus contorta in the field in each of four years from to Survival varied significantly between the years.
In those years when survival was high, significant differences between tree provenance were not found. Three new species are described; two European species, tringarius L. and lineola Fabr., are recorded for the first time; and the previously described species are redefined and new distribution records presented, with a key to the eastern species.
