Abstract: Coquillettidia perturbans is a wide-ranging, prominent nuisance mosquito, as well as a known bridge vector for eastern equine encephalitis virus and West Nile virus. They are strong flyers and vicious biters. Larval control of Cq. perturbans has always proved challenging due to its unusual habit of attaching to emergent vegetation and subsequent difficulty with its surveillance. However, another habit of the species, overwintering and the highly predictable emergence in the spring, should be taken advantage of for economical control. A study on the targeted spring larval control efforts of Cq. perturbans was undertaken in Pasco County, FL. Eight local retention ponds with confirmed breeding of Cq. perturbans were monitored for emergence from March through November of 2020 following treatment in late March. Two emergence traps were placed over clusters of matted floating cattails within each of the sites and collected weekly. Compiled emergence data was used to compare the efficacy of different control strategies targeting Cq. perturbans immatures.
