The Ministry of Forests, Lands and Natural Resource Operations plans to aerially treat about 16,000 hectares of forest in the Williams Lake Timber Supply Area and the 100 Mile House Timber Supply Area to reduce western spruce budworm populations.

The biological agent Foray 48B will be applied by two fixed-wing aircraft (AT-802 Air Tractors) on or about June 13 to July 3, 2015, weather permitting, on sites near:

• Meldrum Creek and Buckskin Lake (west of Williams Lake)
• 114 Mile House
• 70 Mile House
• Lac La Hache
• Loon Creek (east of Clinton)

The western spruce budworm is an insect that is native to B.C. and the Pacific Northwest. In its larval stage, it defoliates Douglas-fir, true firs, spruce and larch trees. A budworm outbreak has the potential to seriously harm or kill trees over large areas.

The pest management plan and maps of the proposed treatment areas can be viewed at the Cariboo Region Forest Health Program office in Williams Lake (640 Borland St., Suite 300) or at the ministry’s Thompson Okanagan Region office in Kamloops (411 Columbia St.).

The maps of the proposed treatment areas in the Cariboo are also available online: https://www.for.gov.bc.ca/rsi/ForestHealth/Western_Spruce_Budworm_Spray_2015.htm

Foray 48B is a biological insecticide that is widely used in British Columbia and is registered with the Organic Materials Review Institute. The active ingredient in Foray 48B is the naturally occurring bacterium Bacillus thuringiensis var. kurstaki (Btk).

This spray only affects moth and butterfly larvae and can be used safely around humans and other animals. Birds, household pets, fish and beneficial insects (including honey bees) are not affected.
