Abstract

Vector borne diseases such as parasitic and viral infection are transmitted by the mosquitoes which are responsible for millions of deaths worldwide. Malaria, dengue, chikengunya, filariasis, encephalitis and yellow fever are major infections transmitted by mosquitoes. The repellent potential of benzene, hexane, ethyl acetate, methanol and chloroform solvent extracts of leaf of the plant Amomum subulatum against the mosquito Anopheles stephensi were tested at three different concentration of 1.0, 2.5 and 5.0 mg/cm².  The arms of volunteer, only 25 cm² dorsal side of the skin on each arms were exposed and the remaining area covered with rubber gloves. Ethanol was served as the control. The control and treated arm were introduced simultaneously into the mosquito cage. In this observation, this plant crude extracts gave protection against mosquito bites without any allergic reaction to the test person, and also, the repellent activity is dependent on the strength of the plant extracts. The results observed suggest that the leaf extracts of the plant Amomum subulatum of different solvents have the potential to be used as an non-toxic, non-irritating safe and effective alternative other synthetic mosquito repellents.
