Abstract: Mosquito species serves as a vector for the transmission of various diseases to human beings. One of these species, Aedes aegypti acts as a vector source for the spread of viral disease Dengue fever. Presently numerous chemi-insecticides and repellants are available which are commonly used as a preventive measure. But, use of these insecticides poses various other ill-effects which includes allergies like skin itching, encephalophathy skin eruption, respiratory disorders as well as harmful to environment. So overcome these adverse effects due to synthetic mosquitocides. There is a need to develop repellants and mosquito larvicidal from botanical origin. They are target specific, biodegradable, cheap, easily available and ecofriend to our environment.
The aim of present review is to shower light on biolarvicides to control vector Aedes aegypti from currently available research literature. For this purpose, original research articles from major databases were studied. Our literature review show that 212 essential oils from 145 plant species belonging to 54 families which had been tested for larvicidal property against Aedes aegypti. These biolarvicides were extracted using various techniques and 19 different solvents. Out of these, 57 extracts of essential oils shows LC50 values less than 100ppm, 17 extracts shows LC50 values of less than 100mg/lit and 42 extracts has LC50 values less than 100 µg/ml. Biolarvicides are safe, effective, target specific, biodegradable and eco-friendly in nature. These should be promoted more to control vector species.
Keywords: Aedes aegypti, biolarvicides, LC50 and dengue fever.
