Mosquitoes alone transmit diseases to more than 700 million people annually. Culex quinquefasiatus mosquitoes are transmitters of diseases like malaria, filaria dengue fever, chinkunguniya and Japanese encephalitis which are among the most serious vector borne diseases. Malaria is a major global health problem. Malaria alone kills 3 million each year, including 1 child every 30 seconds. Botanical pesticides are preferred in comparison to synthetic pesticides, as they are eco-friendly and bio degradable. Plant derived extracts possessing insecticidal activities are no doubt safer and receiving increasing importance as an alternative to synthetic pesticides. Bio pesticides of the plant origin have shown to possess tremendous potential for the safe pest. Mosquitoes have shown a remarkable ability to develop resistant to chemical insecticides. The plant extracts are easy to prepare, inexpensive and safe for mosquito control which might be used directly as larvicidal and mosquitocidal agents in small volume aquatic habitats or breeding sites of around human dwellings. Work is progress towards the evaluation of the potential of insecticidal activity of the plant against insect species and characterization of the bioactive principle that will help in demonstrating the potential of plant species for mosquito control. With this aim in view, the efforts have made to explore the toxicity effect activity of plant Thevetia peruviana which is well known through its everywhere availability. The larvae of Culex quinquefasciatus is used to determining the toxic effect of plant Thevetia peruviana. Mortality, fecundity and longevity of larvae of Culex quinquefasciatus were recorded at 24,48,72,96 hrs of exposure and bio efficacy (LC50) in each was calculated.
