Get ready for adult ABW treatments in central NJ, a little later in northern NJ

In central New Jersey the adult weevil may be approaching peak densities. At Pine Brook Golf Course (Manalapan, NJ) on Wednesday, April 12, I vacuumed up at a rate of 9.7 adults per 10 sec sample, up from 2.7 adults/10 sec sample the week before.

Timing Peak ABW Adult Movement isn't as Easy as Watching the Forsythia

This week, I traveled more than 1,200 miles, visiting golf courses and scouting for annual bluegrass weevil (ABW) adults in Richmond, VA, northern Virginia, central Maryland, southeastern Pennsylvania, all of New Jersey and even a trip out to the eastern end of Long Island. I paid attention to the road, but also to the Forsythia throughout the trip.

ABW NC 2017: Where to start?

“The Incredible Hulk”: ABW monitoring and the weather

Ever ridden "The Incredible Hulk" at Universal Studios in Orlando? I just did. It's not particularly high and starts out with a 45° climb that seems rather boring and slow, only to accelerate half way up like an F-15 jet, launching you into the sky and then on a wild up and down, left and right, gut wrenching ride. Sounds familiar? Yes, that has been the weather this year so far.

Fool me once…Never mind it’s Weather in the Mid-Atlantic.

In the Mid-Atlantic, the weather during February 2017 was mild and drier than normal and golfers were chumping at the first tee at many golf courses on a number of days. In talking with many superintendents the past week, many golf courses had a high number of winter rounds in the month of February.

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.
