Baute Bug Blog

Western bean cutworm trap counts this year have been very low so far.  Although I would normally expect at least the far southwest to be reaching peak moth flight later this week, the traps are not indicating that yet. It might happen but there are not nearly the same number of moths flying around at this time compared to previous…

I’m seeing a lot of pics on Twitter of recent WBC moth catches in traps, which I think is great.  The more people that are trapping, the more data we have to work with to determine when peak flight takes place and when scouting is required. But trap counts do not indicate if a spray is required in corn.  There…
