The goals of this study were to develop methodological changes for applying the bio-pesticide Teknar ® to control the black fly in streams with irregular flow and identify black fly species in three streams (Cafezal, Cambé, Tamapuã) in Southern Brazil. The only regular-flow stream Cafezal was the control stream; the other two streams had irregular flow and were selected to validate the new methodology. The traditional method for bio-insecticide application in the streams under study presented larval mortalities of 99.13% (Cafezal), 59.76% (Cambé), and 13.87% (Tamapuã) . As a result of the new methodology, bio-insecticide concentration was determined according to the specific irregularities of the Tamapuã and Cambé streams and mortality percentages increased to 99.43% and 99.32%, respectively. Among the 229,251 immature Simuliidae collected during the experiment, Grenieriella pruinosum and Chirostilbia pertinax were the most abundant.
