Currently available tools can be used to monitor moth activity (phenology), detect large-scale dispersal flights, compare relative abundance between stands and determine population trend within stands. However, modifications in the trapping system are necessary to reduce variation in trap catch. Additional field trials are required before average trap catch can be used to predict spruce budworm density. Trials should include a minimum of fifteen plots in each region, encompass a range of budworm larval densities and strive to obtain more precise measures of larval abundance.
