First Report of Annual Bluegrass Weevil, \u3ci\u3eListronotus maculicollis\u3c/i\u3e, Damage in Ohio

Annual bluegrass weevil [Listronotus maculicollis (Kirby) (1)] larvae, pupae, and adults were recovered and identified in a sample received by the C. Wayne Ellett Plant and Pest Diagnostic Clinic (CWEPPDC) at Ohio State University on 19 June 2007. Damage to the approaches and collars of four golf course putting greens was detected by the superintendent of Stonewater Golf Club, Highland Heights, OH (a suburb of Cleveland) during the week of 11 June 2007. The superintendent suspected damage from the larvae of the black turfgrass ataenius, Ataenius spretulus (1). Insecticide applications applied to suppress black turfgrass ataenius did not provide adequate levels of control. A sample was sent to the CWEPPDC for analysis where it was determined that the symptoms were not caused by a pathogen. Adult annual bluegrass weevils were observed in the samples. Mature larvae, pupae, callow adults, and adults of L. maculicollis were subsequently identified at the golf course during a site visit on 20 June 2007
