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.

In the Beech Mountain and Banner Elk areas, ABW activity has declined slowly over the past few weeks and no damage has been reported since July. ABWs were active for a longer time period this year compared to what was observed in 2015.
