Activity of Polyherbal Formulated Mosquito Liquid Vaporizer Against Culex quinquefasciatus

Abstract

This is the first report on larvicidal and repellent practises in polyherbal repellent (PHR) formulation BIHER01 (Bharath Institute for Higher Education and Research 01) and its components. Our findings showed that polyherbal (POLH) extracts are promising and noteworthy larvicides for Culex quinquefasciatus which can be linked to polyphenols such as flavonoids, phenols, tannins, alkaloids, saponins, terpenoids, tri-terpenoids, glycosides, cardiac glycosides, protein, carbohydrates, acids and steroids. Based on the time periods used, either a synergist or an antagonistic effect of the phytoconstituents was observed against larvae. On the other hand, owing to its high potential for repellence, PHR was known as an active repellent for Culex quinquefasciatus. Nevertheless, further studies are necessary to establish the contribution to mode of action and repellence of the major and minor elements of POLH extract.
