Larvicidal activity of different natural essential oils against musquito larva

Abstract

Mosquitoes have been a constant problem in the community they continuously transmit serious diseases. Therefore, this study aimed to eliminate larvae of mosquitoes using different natural essential oils isolated from Neem [azadiractha indica], vitex negundo [nirgundi vitex] and clove [Eugenia caryophyllus]. This was done by comparing the span of time the larvae were exterminated upon exposure to treatments with Five various concentrations of the mixture of essential oils. The time (in minutes) of mortality was measured for each treatment application. Results showed a statistically significant difference between various concentrations of oils with alcohol shows positive control of insecticide and control the alcohol. The various concentrations of oils and ethanol displayed a statistically insignificant difference when compared to the positive control. Thedifferent concentrations of essential oils extracts, therefore has larvicidal activity against mosquito larvae, though thorough processing is still necessary for assured efficiency.
