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. Even areas that saw some moderate late-season (late August) damage, have little to no adult activity this week. Now that we have sampled for two full years at multiple sites and have visited 30+ different golf courses to get an idea of ABW distribution and abundance in NC, we can start to get a feel for how this insect behaves and develops in the southern US. We have summarized observations and comparisons for the 2015, 2016 ABW sampling seasons in North Carolina below.

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.
