Peridroma saucia is common in Oregon. But for the past three years, we are detecting them at much higher-than-normal levels in early spring.
The graph below shows pheromone trap counts (# of adult moths per day) in recent years vs. a long term average. Please note that all data points before May 10th are NOT regional averages. They represent only the Corvallis location. These 5 single-location data points are filled with a dot pattern (hard to see, sorry). However, in 2020, the true regional average (peach diamonds) remained higher than normal until June 1st.
Did you know? Last year, the value of utilized production in Oregon was $22.5mil for sweet corn and $20.2mil for snap beans! And together, ID/WA/OR account for 50% of the national utilized production of onions. Check out the new publication re: Economic Pests of Onion – available here.
If you think it’s unusual to post about cutworms in February, you’re right. But there is one in particular that you should know about: Noctua pronuba, the winter cutworm. Here are a few photos of larvae feeding on cabbage in a home garden, Jan 2022 (credit: J.Myers).
You might know that he has contributed over 30 years of expertise to the vegetable industry!! In his honor, our local commission has set up a Go Fund Me page to help with travel funds. Details below but SHHH – it’s a surprise 🙂
Do you grow Asparagus, Beans, Chickpeas, or any other minor/specialty crop of the alphabet? If so.. it’s YOUR TURN to provide input about the recent regulation of chlorpyrifos and how it will affect your production. Sorry, no gift card for this one, but YOUR VOICE IS IMPORTANT!
This survey is VERY SHORT (5 questions total!) and responses remain anonymous. Please consider filling out the survey, regardless of your perceived impact – we need to hear from everyone!
Thank you – Dani Lightle and Jessica Green

A new study from WSU indicates that peas respond to herbivore damage differently depending on if they are attacked by pea weevil or pea aphid first. Transmission of the pea enation mosaic virus (PEMV) is also affected. These biologically relevant interactions have implications for management. A very interesting study, well done, Cougs! https://news.wsu.edu/2021/08/10/pest-attack-order-changes-plant-defenses/
The natural enemy of my enemy is my friend! We start seeing increased activity of beneficial insects this time of year. Everyone can identify a ladybug, a select few know what a lacewing looks like, but did you know that certain flies, beetles, and even yellowjackets also help to regulate pest populations?

You’ll notice that we emphasize the importance of ‘scouting’ on this blog a lot, but what is one supposed to do when they find something? Lots of immature bugs can be found in the soil and it can be difficult to distinguish a “baby” beetle from a fly from a caterpillar, etc. This post might help…
Doesn’t seem possible but we are in week 7 of the 2021 monitoring season. It has been a slow and rather uneventful start, compared to recent years, but predictions of extreme summer heat and drought could change that.
