The 'Evil weevil' - Comes to North Carolina -

摘要

Historically, the annual blue-grass weevil (ABW) has been a significant pest of annual bluegrass and creeping bentgrass in short- and long-mowed turf in the northeastern US. In 2008, it was reported to be damaging fairways and greens on several golf courses in Jackson County, NC. Four years later, annual bluegrass weevil adults and larvae were detected at an additional site in Avery County, NC. This second location was 150 miles northeast of the original site of detection, suggesting its initial appearance was not an isolated incident. Since 2015, research at NC State has been focused on developing a region-specific management plan for this insect pest. Differences in air temperature, soil moisture, day length, and elevation may drastically change how this insect behaves in NC, compared to the northeast.
