Vector control plays a key role in prevention and control of major vector-borne infectious diseases in tropical and subtropical regions. The three main climatic factors that affect malaria transmission and distribution are temperature, precipitation and relative humidity. Aedes aegypti, commonly known as the Yellow Fever Mosquito, is a mosquito that can host the dengue fever, Chikungunya and yellow fever viruses. Medically most important species, Culex quinquefasciatus, breeds in waters polluted with organic debris such as rooting vegetation, household refuse and excreta. Chemical control use of pesticides is still the most important element in the integrated approach to vector control. But they are non-selective and harmful to other beneficial organisms. Hence, botanical have grown very important in controlling the mosquito vectors. Laboratory and field investigations have been made to evaluate the combined effect Clerodendron inerme, Acanthus ilicifolius on three species of mosquito vectors, Anopheles stephensi, Aedes aegypti and Culex quinquefasciatus. Different concentrations of Clerodendron inerme and Acanthus ilicifolius have been tested on the various stages of species of mosquito vectors. Lethal concentrations (LC50 and LC90) were also worked for the different larval stages of mosquitoes. Significant increased mortality was evident after the plant extracts. The lethal effect on mosquito larvae may be due to the active plant compounds on the gut lining of the mosquito larvae. The larval density was decreased after the treatment of plant extracts at the breeding sites (drinking water and ditches water), and hence, these plant extracts of the suitable alternatives of synthetic insecticides for the mosquito vector management.
