Douglas Fir Tussock Moth
Douglas-fir tussock moth (Orgyia pseudotsugata feeds on douglas fir, spruce and ponderosa pine. Defoliation by Douglas-fir tussock moth (DFTM) tends to be much more localized than that of SBW (and hence harder to locate), but high hazard areas are at the lower elevations of Douglas-fir near the edges of open range (such as around Kamloops). DFTM outbreaks develop swiftly and the larvae can decimate foliage on trees to such an extent that mortality in all age classes is common.
Even the first year of defoliation can cause tree mortality, as they feed wastefully on both new and old foliage. Additionally, some people have severe toxic and allergic reactions (Tussockosis) to DFTM larvae hairs.
What is the City of Kamloops doing?
The City of Kamloops, in partnership with the Ministry of Forests and local forest health professionals
is monitoring the tussock moth population using pheromone traps. The results collected will determine
the management direction for the spring of 2009.
