Two Years Sampling in North Carolina: What Have We Learned?

Annual bluegrass weevil activity(ABW) in North Carolina has wrapped up for the 2016 season.

Weevil Emergence on the Fast Track in North Carolina

So far, the weather this year has been all over the place. High temperatures in December, January and February had many worried that we would see record weevil populations as soon as spring emergence began.
