Laboratory bioassays of the juvenile hormone mimic pyriproxyfen against late instar larvae of the nuisance chironomid Polypedilum nubifer revealed that 0.01 ppm pyriproxyfen caused a 90% inhibition of emergence of this species. A field trial of pyriproxyfen at 0.01 ppm was conducted using in situ enclosures. Pyriproxyfen significantly reduced the emergence of P. nubifer and another chironomid, Kiefferulus intertinctus (Skuse), for 24 d. Larval abundances of these species were not affected by the pesticide application. Pyriproxyfen may provide a satisfactory alternative pesticide to organophosphate control agents currently in use, particularly in highly eutrophic wetlands.
