Abstract/Contents: | "Annual bluegrass weevil (ABW) (Listronotus maculicollis) is an established pest of annual bluegrass (Poa annua) and creeping bentgrass (Agrostis stolonifera) golf course putting greens, tees, fairways, and collars in the northeastern and Mid-Atlantic US. A 2017 survey reported widespread distribution of ABW across Delaware, Maryland, and Virginia (DMV). Numerous subsequent cases have been reported throughout Virginia and an increased emphasis on chemotherapeutic suppression. The asynchronous life cycle of ABW leads to the numerous larvicide and/or adulticide applications on golf courses to minimize damage to the turf canopy. The most common adulticides used to combat ABW are pyrethroids, and more specifically bifenthrin. Studies on ABW resistance to pyrethroids have confirmed pyrethroid resistance in many locations throughout the northeastern US, but only five percent of DMV locations suspected resistance. To date, pyrethroid resistance has not been confirmed in Virginia outside of metropolitan Washington, DC. Therefore, our primary objective was to further define ABW distribution across Virginia with a secondary objective of assessing sensitivity to bifenthrin. Seventy-two percent of golf course superintendent survey respondents (n=47) reported seeing ABW at their facility with positive confirmation at 22 locations. Adult ABW from six locations representing Virginia's geographic regions were subjected to bifenthrin (0.11kg ai ha-1) bioassays and compared against a sterile water control. Mortality of adult ABW treated with bifenthrin were higher than untreated ABW across all locations (P ⤠0.057). Our research confirms that ABW distribution is more widespread across Virginia than previously reported but that population samples are currently still sensitive to bifenthrin at the rate tested." |
