ABSTRACT

Mosquitoes plays a vital role in transmitting number of diseases that are harmful to human beings causing malaria, filariasis and viral diseases, such as Japanese encephalitis, dengue, and yellow fever. Mosquitoes have become resistant to traditional chemical pesticides and there is growing concern about the potential health and environmental degradation due to these products hence efforts have been taken to control the mosquito using biological substances. In the present study plant oil was used to control the mosquito larvae. The efficacy of different concentration of the plant oil viz 100.0 ppm, 200.0 ppm, 300.0 ppm, 400.0 ppm, 500.0 ppm and 1000 ppm for their larvicidal activity against Aedes aegypti (l.) was tested. However, the maximum larval mortality in minimum time was detected in 1000 ppm concentration, However, the highest concentration studied for the effective of extracted from Zanthoxyulum rhetsa Roxb Dc carpels oils was 500.0 ppm (Table 9, Graph 9 & Table 10, Graph 10) for dried carpel oils and 400 ppm (Table 7, Graph 7& Table 8 Graph 8) for fresh carpel oil. The results revealed that larvicidal properties of Zanthoxylum rhetsa (Roxb.)DC fruits encourages further effort to investigate the bioactive compounds that might possess good larvicidal properties when it will be isolated in pure form. These results obtained are promising in thus creating new effective and affordable approach to the control of vector mosquitoes.
