Repellent Potential of Tageteserecta L. and Callistemon brachyandrus Lindl. Against Mosquito Larvae for Formulation of Herbal Repellent Compounds

Abstract

To avoid harmful effects of commercially available mosquito repellent creams in market, an attempt has been made to prepare herbal formulations from natural products such as flowers of Tagetes erecta L. and leaves of callistemon brachyandrus Lindl. These are ornamental plants, flourishing in India. All parts of the plant, from root to seed possess a multitude of phytochemical secondary metabolites and also responsible for repellent activity. To evaluate the repellent potential, phytochemical studies, larvicidal activity, smoke toxicity and repellent activity tests were performed against Anopheles stephensi, Culex infulus and Aedes agepyti. Water extract of Tagetes erecta L. showed of mortality rate of 40%, 40%and 50% and Callistemon brachyandrus Lindl. water extract showed 20%, 13.33% and 40% mortality rate against Anopheles stephensi, Culex infulus and Aedes agepyti respectively. These plant extracts were used to formulate herbal repellent compounds such as incense log and cream. Repellent activity test for cream formulation showed 89.87%, 87.5% and 90% protection and smoke toxicity test for incense log showed 66.25%, 70% and 67.5% protection against Anopheles stephensi, Culex infulus and Aedes agepyti respectively
