ABSTRACT
Mosquitoes are the major vectors considered to transmit diseases including dengue, malaria, filariasis, and Japanese encephalitis to humans. Mosquito populations thrive in the many breeding places made available and created by society. Although many synthetic ways are available to control mosquito vectors, natural approaches are ecofriendly, easily available, and come at a low cost. Here we review that the cyanobacteria were found to be a good biological agent as biolarvicide. The secondary metabolites from cyanobacterial genera such as Westiellopsis, Oscillatoria agardhii, and Synechococcus were found to control the larvae of Aedes aegypti, Aedes albopictus, Anopheles stephensi, and Culex quinquefaciatus and Culex pipiens by the synthesis of toxins like anatoxin-a and microcystin-LR. This chapter describes the isolation and characterization of mosquito larvicidal compounds from cyanobacteria and their unsaturated fatty acids to control mosquito populations.
