cutworm moths on a round screen with muddy background
Trapping 50+ moths…in just 3 days… and it’s only May…is…concerning!

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.

Alternatives to Chlorpyrifos – 2nd survey

Posted on by

NEW!

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

Pea Weevil/Aphid info

Posted on by

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/

Natural enemies

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?

One-Third of ’21

Posted on by

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.

  • Data tables are available for week 6 and week 7
  • Looper levels remain VERY low
  • An early (Apr-May) boom of cabbage white butterfly means greenworms could be present in gardens and fields – scout accordingly
  • Aphid scouting will once again be part of VegNet’s regional monitoring effort. See the aphid profile page for more info
