With the first spotting of early instar immature ABW, now is the time to revisit the plan of attack for ABW management.
An asynchrony between ABW population development and plant phenology/GDD has been noticed this spring, making optimal adulticide application timings challenging.
This week and next week are the times to apply adulticides and/or prepare for larval monitoring.
GDD readings tell us we’re at or near peak adult activity in our region, but phenological indicators don’t fully support the observation. Scouting is...
Larvae sampling suggests we are a little behind expectations based on GDD's and plant phenology, but with upcoming warmer temperatures, I expect the larvae...
Predicting peak ABW adult densities this year is a real headache, but I expect peak weevil densities to start sometime this week in central and northern New Jersey.
We are a little behind on our GDD in VA compared to recent years, and the weather has made it difficult to figure out ABW activity.
The correlation between seeing an increase in ABW adults and the forsythia 50% green (leaves) and 50% gold (flowers) has long been the target, but this...
With expected warmer temperatures in the coming weeks, we expect adult ABW activity in New England to peak near the end of April.
Slow initial start to the ABW season in North Carolina, but things are humming along now!
Our ABW adult sampling showed a slight increase in adult ABW activity. Could this be the peak?
There’s been a dramatic decoupling between accumulated GDDs, plant phenology, and adult ABW migration. The divergence we’re seeing this year highlights...
Two courses in the northern Chicago suburbs were the first to report ABW presence in Chicago in 2023, setting the stage for ongoing tracking this year.
ABW are seen in pitfall traps installed in roughs between overwintering sites and low-cut turf mixtures of annual bluegrass and creeping bentgrass in Ohio.
The winter of 2024/2025 brought significant snow, wind and ice in the Mid-Atlantic and Northeast regions. What does this mean for ABW?
Based on the weather forecast for NJ, we can expect to see the beginning of forsythia full bloom and some adult ABWs on the short-mown turfgrass areas.
Spring appears to be here in central PA, and with it comes the start of the ABW monitoring season.
ABW distribution is currently isolated to the Bluegrass region of Kentucky, but all regions should be aware and scout diligently.
