Recent Paper Assessed Risks For Adult Butterflies Exposed To Mosquito Control Pesticide Naled


06/27/2012

USGS scientist Dr. Tim Bargar (USGS Southeast Ecological Science Center) recently published a new method to prospectively assess risks for adult butterflies exposed to the mosquito control pesticide naled. Prior to this paper, no published method existed for estimating adult butterfly exposure to a pesticide applied as an ultra-low volume spray. The paper’s findings provide a guideline value for naled deposition that managers can use to minimize the risk of death for adult butterflies. Although there remains uncertainty about the relationship between application rates and deposition levels, the findings are still useful for making decisions about mosquito spraying. The article, Risk assessment for adult butterflies exposed to the mosquito control pesticide naled, was published in the journal Environmental Toxicology and Chemistry.
