| Abstract | ||
| The current study was conducted to find out the effect of lethal concentrations of alcoholic and aqueous extracts of three powders are Murraya koenigii L., Syzygium aromaticum and Capisicum annum of the 3rd instar of mosquito Culex pipiens molestus (1-7 days) after treatment, using different concentrations of those extracts. The results showed that all the extracts used had deadly effects on mosquito larvae. The concentrations 400 ppm of alcoholic extract of Murraya koenigii and 200 ppm of aqueous extract of the same extract caused 100% mortality of larvae after four days of treatment. The alcoholic and aqueous extracts of Capisicum annum of the concentrations 500, 1000 ppm respectively caused 100% mortality after six days of treatment. While when using the alcoholic extract of Syzygium aromaticum the concentration 1000 ppm caused 100% mortality of larvae after five days of treatment and the concentration 1500 ppm of aqueous extract of the same extract caused 100% mortality of larvae after six days of treatment. | ||
