Original content is great, but sometimes it is unnecessary to reinvent the wheel, or in this case, the YouTube video about armyworm damage in wheat. We are starting to monitor true armyworm (Mythimna unipuncta) in the PNW, but efforts from Midwest states are much more deliberate because the species can be so damaging to large… Continue reading

Regional trapping in Tillamook county has been ongoing for 6 weeks. We’ve recently begun to incorporate GIS maps to make it easier for program leaders and participants to visualize ‘hot-spots’ of armyworm moth activity. Of 15 total monitoring sites, positive trap counts this week are confined to a 5 mi2 area, centralized around Tillamook city… Continue reading

Other regional agencies will be initiating a trapping program for this species and other armyworms. The presence of moths reported here are considered ‘non-target by-catch’ = the large yellow underwing moths (Noctua pronuba) were caught in pheromone traps deployed for other species in another program (OSU VegNet). Nevertheless, it has proven to be at least… Continue reading

Pyraloidea is the third largest superfamily of the Lepidoptera, and is comprised of two families – Pyralidae and Crambidae. Together, there are about 16K species worldwide. Within the… Continue reading

Soil type and the parameters associated with it (water holding capacity, %OM, etc.) could be important as we continue to investigate armyworm population dynamics. The Web Soil Survey is a useful, interactive tool that is freely available to all. We are trying to discern why certain sites in our Tillamook trapping effort have 10-20X the… Continue reading
