Abstract

A study of filamentous algae and its relation to malaria vector control was conducted during the dry season in several lagoons at the north coast of Bali. Floating masses of these algae under the sunshine barricated the spread of solar-triton larvicide, reducing tremendously the effectiveness of the larvicide. Identification of the genera of these algae under the subphyllum of CYANOPHYTA (Blue Algae) in the family of Cyanophyceae were Oscillatoria, Spirulina, Phormidium, Rivularia, Nostoc, and Anabaena; under the subphyllum of CHLOROPHYTA (Green Algae) in the family of Chlorophyceae were Enteromorpha, Spirogyra, Mougeotia, Zygnema, and Oedogonium. The surface of water in between the floating masses of algae were an exellent breeding place of mosquitoes mainly Anopheles sundaicus. The density of Enteromorpha, the main attractant of An sundaicus compared to other filamantous algae, has no direct relation on the density of An. sundaicus larva. Hence Enteromorpha could only be considered as the indicator of the presence of larvae and not as the indicator of population densities of larvae Lagoons surrounded with mangrove plantations did not harbour filamentous algae and larvae of An. sundaicus were not found.
