Author(s): KM Remia, S Logaswamy and R Shanmugapriyan
A laboratory study was conducted to evaluate the efficacy of repellency of Hyptis suaveolens and Ocimum gratissimum against the adults of Aedes aegypti. The methanol extract of H. suaveolens at 0.03, 0.05, 0.075 and 0.1 mg/cm² offered 50.00, 66.67, 71.43 and 75.00 percent protection against the mosquito bite. The percent protection against the mosquito bite was 33.33, 50.00, 57.14, 60.00 and at 0.03, 0.05, 0.075 and 0.1mg/cm². Synergistic action was observed when the plant extracts were mixed in equal quantity and the percent protection was extended up to 83.33. Mosquito coil made with the extracts of H. sauveolens and O. gratissimum provided 75.31 and 70.37 percent protection from mosquito bite. Combined use of plant extracts increased the percent protection than with individual plant extracts.
