Management of common forest pests within the Prince George Timber Supply Area Neuvonen, Warren


This paper describes three insects that affect BC forestry, specifically the Prince George Timber Supply Area: White pine weevil (Pissodes strobe), Forest tent caterpillar (Malacosoma disstria), and Spruce beetle (Dendroctonus rufipennis). These insects pose a challenge to forest managers by: defoliation of regenerating seedlings, tree mortality, and defoliation of deciduous tree species. The main purpose of this paper is to provide recommendations from studies conducted across North America and Northern Europe, and not to describe the insect in great detail. The aim is to find effective, and cost efficient methods of preventing insect outbreaks in BC that are detrimental to environmental, economic, and social factors. The mountain pine beetle has not been included in this review; the populations are declining, and a future outbreak will not occur in decades. This paper’s scope focuses on native insect populations in BC, and does not describe alien insects affecting BC’s forests. This paper also does not discuss the numerous fungi that affect trees.
