We are rapidly advancing through the first generation in Pennsylvania. Each week seems to bring a new WeevilTrak stage—and a ton of rain. Today is May...
The bizarre weather year continues for Pennsylvania. Last week alone (April 30 to May 4) saw our ABW population shift into a higher gear.
We are nearing the end of April and are currently running about 100 growing degree days (GDD) behind where we were in 2017 in central and western Pennsylvania...
The Turfgrass Entomology Laboratory at Penn State is looking forward to another WeevilTrak season…..whenever that may be. The recent snowfall generated...

All three of the sites that our lab monitors for WeevilTrak advanced to Stage 1 (Apply Adulticides) during the last week (April 18-22). These areas include...
We are hurtling toward the start of ABW season in central and western Pennsylvania. This has been a bizarre season so far, but we have come to expect...
I have received quite a few reports of ABW damage in the last few weeks, occurring on golf courses from northern New York to southern Virginia. The reports...
