Abstract: Abstract: Ocimum sanctum was tested for its larvicidal and water sedimentation properties; the fruit ethanol and methanol extracts of Phyllanthus emblica were tested for phytochemical, larvicidal, oviposition-deterrent and ovicidal activities. Results emphasized that plant extracts have high toxicity against the egg and larvae of the malarial vector Anopheles stephensi and also have water sedimentation properties. LC50 of Phyllanthus emblica against Anopheles stephensi larvae ranged from 33.08 ppm to 81.26 ppm and from 23.44 to 54.19 ppm for ethanol and methanol extracts, respectively. Phyllanthus emblica also showed excellent ovipositional deterrent and ovicidal activities. The oviposition activity index value of ethanol and methanol extracts of Phyllanthus emblica at 500 ppm were -0.80 and -0.92, respectively. Ocimum sanctum includes both insecticidal secondary compounds, amino acids (glycine, lysine), vitamin C and other substances, that make treated water suitable for human consumption. Water quality parameters such as color, turbidity and pH were analyzed in the water samples (pre-treatment and post-treatment of plant extracts) taken from the breeding sites of mosquitoes. Hence, the plant product can be used as both mosquitocidal and water purifier.
