Isolated high ABW pressure and a shift to more callow new adult ABW pushes us closer to Phase 3 applications.
ABW populations in Chicago’s north suburbs are advancing from late instar larvae to pupae as GDDs rise, with adult emergence expected in the coming weeks.
Despite strong program performance, warm, dry conditions may intensify ABW damage—even at low populations—making continued scouting essential.
We saw adult activity increase at all northern sites and detected early signs of damage by the end of May and have continued to observe a prolonged increase...
ABW damage is appearing across Ohio as 1st-generation adults emerge.
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.
