ABW update for late September, 2020 in Virginia – Just a few lingering adult weevils

During this last week of September, we are seeing pretty much only a few lingering adults at our three Virginia WeevilTrak locations that will likely be the overwintering population.

They are Either Here or They are Not! The last of ABW blogs (I hope) for 2020!

2020 will go down as crazy and wild year in many factors of our lives. 2020 was a pretty temperate year for annual bluegrass weevils (ABW) as a whole. I only saw a handful of heavily damaged areas this year compared to what I typically see in my travels. This was a good thing

Where are the Annual Bluegrass Weevils in the Mid-Atlantic?

The 2020 year has been one of uncertainties in many areas and it’s true for annual bluegrass weevils (ABW) as well.

ABW larvae abound: Is this the 2nd summer generation?

Annual bluegrass weevil (ABW) larvae seem to be popping up in many places across New Jersey. It seems rather early for larvae of the 3rd ABW generation (the 2nd summer generation) to already start causing damage.

WeevilTrak Update for August 11, 2020

I was just telling a superintendent the other day that 2020 has been the quietest annual bluegrass weevil year that I can remember. However, the last 10 to 14 days have produced the most S.O.S. calls of the year, and probably more insecticide applications out of desperation.

As of the last week of July, we are seeing a mix of ABW life stages from small larvae to adults at our three Virginia WeevilTrak courses.

Does the Weather Person have the Perfect Job?

Trying to predict annual bluegrass weevil (ABW) activity after the middle of July is like trying to predict rainfall in the Mid-Atlantic during the third week of July.From this point on, it’s best to scout your site and make applications as needed depending on your threshold for damage and what you are finding. If your golf course has a history of late summer and even damage into October or later, it’s important to stay diligent with your efforts.

ABW larvae of 1st summer generation: Time to scout for and control if necessary

Annual bluegrass weevil populations in central and northern New Jersey currently consist of all stages from spring generation adults through large larvae of the 1st summer generation. Scouting for the large larvae should be ongoing. Applications should then be made to the affected areas as soon as significant larval populations are detected.

Fairly quiet on the ABW front…

With a few exceptions, annual bluegrass weevil (ABW) activity in North Carolina has been quiet since early June. This is typical for this area. Most years, peaks and corresponding damage start in March-April and continue through Memorial Day. June and July tend to be relatively quiet, and then we see the occasional spike in activity again in early August. So, if you have not had an issue for more than a month, continue to keep an eye on the adult activity in case we see an increase in the next two weeks.
