Mosquito control is essential to prevent mosquito borne diseases such as dengue, chikungunya, Zika and filariasis. Synthetic insecticides such as organophosphate and pyrethroids are commonly used for mosquito control program. Synthetic insecticides are effective, nonetheless cause adverse effects on the environment and human health. Due to their hazardous effects, alternatives are required for mosquito management. One such alternative approach is to explore the floral biodiversity. Insecticidal compounds from natural sources, notably from plants are promising for managing such vectors. Hence, the study aimed to analyze the ovicidal potential of ethanol and acetone leaf extracts of Caesalpinia pulcherrima. Effect of ethanol and acetone leaf extracts of Caesalpinia pulcherrima on the hatchability of Aedes aegypti eggs were determined adopting the standard procedure. Per cent hatch of eggs placed in control medium was 95% where as in 0.1, 0.3, 0.5, 0.7%. concentrations it was 75, 50, 25, 15 (ethanol) and 70, 55, 30, 20 (acetone), respectively. 0.9% completely arrested egg hatching in both extracts. From the above, the ethanol and acetone leaf extracts of C. pulcherrima can be recommended for the development of ovicides against Ae. aegypti eggs.
