[Control of Simuliidae with an emulsifiable concentrate of Bacillus thuringiensis].
The effects of the three flowable concentrate formulations of Bacillus thuringiensis var. israelensis (H-14): Teknar (Zoecon, Sandoz Inc.), Vectobac (Abbott Labs.), and Bactimos (Biochem, Solvay Labs.) against Simulium pertinax were evaluated in 24 streams in the North Littoral Zone of São Paulo State, Brazil. There was no significant difference in effective carry (80% or more mortality) among the formulations when applied at the rate of 10 mg/liter for one minute. There was a strong correlation between stream discharge and effective carry of the formulations, except in the case of Teknar, possibly due to the influence of the physical characteristics of the streams where evaluation was conducted.
