ABW counts have been quite variable across locations this year, highlighting the need to scout your own course closely.

Temperatures are starting to consistently warm up around here. As a result, increased ABW adult activity is on the horizon.

Most locations are entering a two-week or so stretch between the end of the first-generation larvae and the formation of first-generation adults.

The 2026 growing season has been a roller coaster of weather, and significant ABW damage is now showing in untreated plots and on golf courses.

Turf damage caused by ABW has been recorded earlier than expected, with larvae causing damage in untreated turf.

ABW adult activity has declined, but the detection of early larval instars signals the start of larval development in north suburban Chicago.

If you are thinking about insecticide applications against the mid-size larvae, now is definitely the time to start checking for larvae.

We started picking up on some early instar larvae in late April but have really been seeing some larger larvae in our research trials and WeevilTrak scouting.

After an unusually warm spring pushed us well out in front, the season has, in a sense, righted itself.

ABW stages are about 10–14 days advanced compared to last year in Ohio. Scout to ensure proper larvicide timing and avoid pesticide overuse.

Observations suggest the window for targeting adult populations is narrowing across the region.

After a mostly warm April, we are well ahead in plant and insect development but have not found larvae yet.

Despite low pressure, ABW larvae are maturing. Scout locally to ensure timely applications.

This spring is unchartered territory and will require intensified larval sampling.

Spring of 2026 seems like yo‑yo weather with dry conditions and major temperature swings.

The 2026 ABW season is in full swing in Central and Eastern Virginia.

Across our WeevilTrak Plus sites, GDD accumulation climbs, Forsythia is in (or close to) full bloom and peak ABW adult activity is just around the corner.

ABW adult activity remains minimal at Virginia Tech Golf Course and Blacksburg Country Club.
