Environmental fate model for ultra-low-volume insecticide applications used for adult mosquito management

► No model can accurately predict deposition of insecticides applied with ultra-low-volume technology for mosquito management. ► We perform field studies to measure actual environmental concentrations of insecticides. ► We develop a validated model to predict the deposition of insecticides after ultra-low-volume applications. ► The model demonstrated good predictive ability and was validated.
