Abstract

Ataenius spretulus (Haldeman) is a serious pest of golf course turf in the eastern and mid-western United States. Larvae feed on roots of annual bluegrass, Poa annua L., bluegrass, P. pratensis L., and bentgrass, Agrostis sp., causing the turf to die in small irregular patches. There are at least 2 generations each year and adults of the 2nd generation overwinter. Control experiments conducted in Ohio and Connecticut showed that CGA-12223 (O-[5-Chloro-1-(1-methylethyl-1H-1,2,4-triazol-3-yl] O,O-diethyl phosphorothioate) gave best control followed by fensulfothion. Control with trichlorphon, diazinon, fonofos, and chlorpyriphos was fair-poor. Laboratory contact toxicity tests on adults show that cyclodiene resistance has developed in Connecticut, New Jersey, New York, and Ohio.
