Remember to subscribe to receive up-to-date information via email! We alert you of insect pest activity for nearly half the year (24 weeks), the service is currently free, and we promise to not bother you for the other 28 weeks, nor share your email address.

Notable trends during the week of June 24th include:

  • Cabbage Looper moth counts continue to be extremely high, we are likely seeing the 2nd generation, which is considered the most damaging for brassica crops.
  • Armyworms have wide host ranges but can be especially damaging in grasses, pastures, and field crops.
    • One species, in particular, seems to be booming this year. It is called the “Thoughtful Apamea“, which is closely related to glassy cutworm, but habits and host range are largely unknown.
    • Conversely, True Armyworm is well-studied and we have been collaborating on a project to monitor them in Tillamook County. So far, counts are low, but if you’re interested, trap counts will always be posted here: https://beav.es/ZQM
  • Beneficial Insects include pollinators, predators, and parasitoids that provide some type of ecosystem service. As natural enemies of pests, their activity tends to lag slightly. We have noted an increase in Syrphidae and Tachinidae flies this week, as monitored by passive sampling techniques.
