A Survey of Phyllophaga Species Associated with Oklahoma Golf Courses. Jake Doskocil 1, Tom Royer 1, Nathan Walker 1, Greg Bell 1, James Reinert 2 (1)Oklahoma State University (2)Texas Agricultural Experiment Station

Objectives Determine the species composition of Phyllophaga associated with turfgrasses in Oklahoma Determine the seasonal occurrence of Phyllophaga spp. associated with turfgrasses in Oklahoma

Survey Sites Figure 1. Stars denote the location of golf courses were light traps were placed

Results

Regionally important –Central – P. crinita, P. crassissima –South – P. crinita –Northwest – P. glabricula, P. crassissima –Northeast – P. glabricula Notable –South – P. congrua

Results Figure 3 Flight period of Phyllophaga beetles collected from 7 golf courses in Oklahoma, (The checkered areas denote the peak flights for the 5 most abundant species.)

Current Research Determine which of these species is turf inhabiting –Larvae have been collected from regionally corresponding locations for rearing. –DNA sequencing of COII for use in identification of larvae.
