ABSTRACT: The acetone extract of metal tolerant Oscillatoria was tested under standard laboratory conditions for larvicidal activity against the mosquito Culex quinquefasciatus. Oscillatoria amended with BG11 medium and with zinc, copper, chromium and cadmium (1mg/ml each) were used for this study. Results showed that Oscillatoria challenged with zinc was the most effective having a LC50 of 73.76 mg/L. This study showed that extracts from algae used for bioremediation can be utilized as mosquito larvicides.
