There are approximately 20 pest wireworm species in Canada, of which three have been introduced. Until recently, these three (Agriotes lineatus, A. obscurus, and A. sputator) were the only species for which sex pheromones had been identified and used for monitoring and wireworm risk assessment purposes. However, since 2010 there has been a renewed interest in identifying the sex pheromones of native North American pest species, and to date structures have been described for various species in at least five genera, including Agriotes, Melanotus, Selatosomus, Cardiophorus and Limonius spp. Here we discuss results of field testing some of these new compounds, the potential of combining different pheromones for managing co-occurring heterogeneric species, the distribution of different wireworm pest complexes in Canada and species for which pheromone structures (if present) still need to be elucidated, and work done to date to develop semiochemical-based management strategies (mass trapping and mating disruption) in Canada. Several knowledge gaps will be identified, as well as suggestions and proposed work to address these.
