Small Rise in Armyworm Detections

Here’s the latest armyworm monitoring update from UCCE Rice Farming Systems Advisor Luis Espino:

Week of August 3

The number of moths has increased slightly in most locations. It seems the upward trend is starting and numbers should continue to go up in the coming days. I have found very few worms in the field and have seen very little injury. 

Western yellowstriped armyworm news:

I was notified of an outbreak of western yellowstriped armyworms in alfalfa in northern Glenn County. Looks like worms were moving out of a recently cut alfalfa field. I have not seen these worms feeding on rice in the past five years. For more information, visit the armyworm monitoring website.
