Background: The compatibility of spindor dust (spinosad), a bio-rational larvicide derived from the fermentation of a soil bacterium Saccharopolyspora spinosa, was investigated on the mosquito fish, Poecilia reticulata, and larvae of both Anopheles gambiae s.s. and Culex quinquefasciatus mosquitoes.
Methods: Three replicates of each to different concentrations of spinosad dust under static bioassay were performed to determine the acute toxicity of the larvicide on each organism. To investigate the genotoxic and ultrastructural changes in P. reticulata, the fish were exposed for 28 days to low concentrations of the test larvicide capable of killing 30% and 70% of Cx. quinquefasciatus larvae. Thereafter, gill and intestinal cells were removed at days 3 and 28 respectively, and then processed for epifluorescent and transmission electron microsc.. View More»
