The white satin moth, Leucoma salicis (L.), has been detected as a pest of urban
trees in Thunder Bay, Ontario. Surveys were conducted in urban environments
following the discovery of this introduced species to determine the extent of damage to
urban trees and distribution within Thunder Bay. Further information was compiled to
identify ways to locally mitigate the effects of the satin moth. Early management
strategies, such as high-pressure water washing, Tanglefoot, and Btk should be utilized
as short-term management approaches, and biological control agents, such as parasitoid
wasps, should be implemented as a long-term management strategy to mitigate severe
infestations.
