Effect of four chlorophytes on larval survival, development and adult bodysize of the mosquito Aedes aegypti

The effect of four microalgal chlorophytes, Chlorella vulgaris, Scenedesmus quadricauda, Chlorococcum sp. and Ankistrodesmus convolutus, on the surviv al, larval development and adult body size of the mosquito Aedes aegypti wa s investigated. The percentage mortality of larvae fed with C. vulgaris, Ch lorococcum sp. or S. quadricauda after six days was 100%, 84% and 88%, resp ectively. Delayed pupation and body size reduction of the mosquitoes fed wi th C vulgaris, Chlorococcum sp. and S. quadricauda were observed. In contra st, larvae fed with A. convolutus were bigger than those fed with normal in sectory feed. The study showed that C. vulgaris, S. quadricauda and Chloroc occum sp. have potential to be used as larvicidal agents.
