Armyworm Monitoring

Armyworm Monitoring 2017 - Aug 17

 

Number of moths in traps increased in most locations, specially in the Butte and Yolo traps. This increase might correspond to the second moth flight we see every year. Compared to last year, this flight is later. There is still a risk of injury to fields where heading has just began. Fields with mature panicles may be at less risk of injury.

In 2016, worms were observed in fields only after catches were around 20 monts/trap/day.
