Resumen:
The major urban mosquito species in southeastern U.S.A., Aedes albopictus (Skuse) and Culex quinquefasciatus Say have become increasingly difficult to control due to insecticide resistance. The efficacy of a new EC formulation of d‑d trans‑cyphenothrin EC, applied as an ultra‑low volume (ULV) aerosol from a truck mounted LECO® Model 1600 cold fogger, was evaluated at various dosages (0.5, 1.0, 2.0 & 4.0 g a.i./ha) against Ae. albopictus and Cx. quinquefasciatus in sentinal cages at various distances (10, 25, 50, 100 meters) downwind from spray application compared to untreated controls and treated control of Scourge® (resmethrin). Mortality of both species was 90% or greater after exposure to the 2.0 g a.i./ha concentration of d-d trans-cyphenothrin EC. Even at the lowest concentration (0.5 g a.i./ha), exposure to d-d trans-cyphenothrin EC produced higher mortality in caged Ae. albopictus and Cx. quinquefasciatus than exposure to Scourge®.
