Abstract: The present study focussed on the larvicidal effects of bioactive compounds in the crude aqueous extract of G. gummi-gutta leaves of Garcinia gummi-gutta against the late III or early IV instar mosquito larvae. The aqueous extract was used at varying concentrations of 20%, 40%, 60%, 80% and 100% of the crude extract, containing 45, 90, 133, 180 and 225 mg/ml of the extract. Of the five test concentrations used, 100 % mortality rate was observed for the extracts containing 180 and 225 mg/ml at 25 and 15 minutes, respectively. For the test samples of 40, 60, 80 and 100 % extract (containing 90, 133, 180 and 225 mg/ml, respectively) the LC50 values obtained were 30, 20, 15 and 10 minutes, respectively.
