Ten field tests were conducted in east central Florida to investigate the acute toxicity of fenthion thermal fog, fenthion ultra low volume spray, malathion ultra low volume spray, and naled ultra low volume spray to non-target estuarine organisms. Animals tested included adults of the calanoid copepod Acartia tonsa, eggs of three species of fish, and juveniles of three species of fish. Significant mortality occurred only for copepods exposed to fenthion thermal fog in one test and naled ULV in one test. Environmental factors appear to influence the sensitivity of copepods to the insecticides. Florida Atlantic University.
