Baseline susceptibility to pyrethroid and organophosphate insecticides in two old world sand fly species (diptera: psychodidae). Army Medical Department Journal. p. 3-9.Interpretive Summary: Phlebotomine sand flies are blood-feeding insects that transmit pathogens causing Leishmaniasis.  Sand flies pose a significant threat to U.S. military personnel when deployed to the Middle East and Africa where those disease insect vectors are endemic.  A sand fly research project was initiated by USDA scientists with support from the Department of Defense’s Deployed Warfighter Protection (DWFP) Program to evaluate the susceptibility of two old world sand fly species, Phlebotomus papatasi and P. duboscqi, to a number of commonly used pyrethroid and organophosphate insecticides. A simple glass vial bioassay technique, which is a modified version of the CDC bottle assay, was utilized in this study. The exposure time-mortality relationship at a given insecticide concentration was determined for each of the insecticides, and their relative toxicity against these two sand fly species was ranked based on bioassay results. This study validated this new bioassay technique and also generated baseline insecticide susceptibility data that can aid future insecticide resistance monitoring work

A simple glass vial bioassay technique, which is a modified version of the CDC bottle assay, was utilized in this study. The exposure time-mortality relationship was determined and used to rank relative toxicity of the insecticides tested.  Prallethrin and '-cyhalothrin were most toxic to both sand fly species, followed by deltamethrin, cyfluthrin, cypermethrin and permethrin, and etofenprox.  The order of relative toxicity of organophosphate insecticides against P. papatasi was diazinon = chlorpyrifos > coumaphos > dichlorvos.  Chlorpyrifos appeared to be more toxic than malathion and carbaryl against P. duboscqi sand flies.
