Title: Susceptibility Of Populations Of Simulium (chirostilbia) Pertinax Kollar, 1832 (culicomorpha, Simuliidae) To Eemephos And To Bacillus Thuringiensis Var. Israelensis-based Formulation [susceptibilidade De Populações De Simulium (chirostilbia) Pertinax Kollar, 1832 (culicomorpha, Simuliidae) Ao Temephos E A Um Formulado à Base De Bacillus Thuringiensis Var.

Abstract: The use of wooden troughs on stream beds, artificially colonized by blackfly larvae, is proposed for larvicide evaluations. Mortality was recorded 3 or 4 hours after treatment. Larval susceptibility was also evaluated utilizing the LT50 criterion. In there field assays Simulium (C.) pertinax populations from the litoral of S. Paulo and Rio de Janeiro States were shown to be resistant to temephos, even when subjected to high concentrations. Vectobac 12 AS, a Bacillus thuringiensis var. israelensis product, was shown to be more potent against late instar larvae and efficient in concentrations higher than 7,200 ITU/l (10 min). The LT50 to 3,744 ITU/l (10 min) was calculated as 70.9 min.
