Armyworm Monitoring

Armyworm Monitoring 2017 - Aug 31

 

Numbers have decreased in all traps, except for the trap in Yolo County. I have seen very little armyworm injury on headed rice this year. It is unlikely that worms will injure mature panicles. Looks like the armyworm season is over.

Week2

 

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