Abstract

This research aimed to find out larvicidal activity of ethanolic extracts of the Citrus maxima peels; seeds were assessed in order to larvicidal activity against the mosquito larvae under the laboratory condition. Mosquito larvae were treated with different concentrations of the ethanolic extracts (10 mg/mL to 40 mg/mL. The larvae stages were more susceptible to the ethanolic extracts. Whereas, the extracts of C. maxima peel gave the mortality rate of 93.3 % twelve hours after the treatment at 40 mg/mL while the mortality rates were 40.0%, 60%, and 73.3 % at the lower concentration of 10 and 30 mg/mL respectively, 12h after treatment. This botanical larvicide could be used in place of the synthetic because of it is cheap, environmental friendly, easily available biodegradable and safe.
