Abstract:The joint toxicity of coprecipitated, free-acid, nondispersible and dispersible formulations of erythrosin B and fluorescein was studied on fourth-instar Culex pipiens quinquefasciatus Say. When used alone or in combination, the dispersible formulation was more toxic than its nondispersible counterparts. The dispersible 1:1 and 1:3 (erythrosin B: fluorescein) combinations were more toxic and faster acting than any of the components used alone. The nondispersible coprecipitated formulation failed to enhance toxicity. However, the dispersible combinations showed synergistic action, with the 1:1 combination exhibiting a greater degree of synergism than the 1:3 combination. The 24-h dark incubation treatment increased the toxic effects of the coprecipitated dispersible formulation and erythrosin B used alone, but suppressed the toxicity of fluorescein.
