Field trial of Abate and Teknar for Simulium (Diptera: Simuliidae) control in India

Simulium breeding was eliminated in a river up to 30 km with 0.1 ppm Abate (temephos) for 30 min exposure. Teknar (Bacillus thuringiensis var. israelensis) at 10 ppm for 10 min exposure resulted in 98.4% and 87.9% reduction up to 20 m in 2 sections of a small stream.
