| Abstract: | The effect of four microalgal chlorophytes, Chlorella vulgaris,Scenedesmus quadricauda, Chlorococcum sp. and Ankistrodesmus convolutus, on the survival, larval development and adultbody size of the mosquito Aedes aegypti was investigated. The percentage mortality of larvae fed with C. vulgaris, Chlorococcum sp.or S. quadricauda after six days was 100%, 84% and 88%,respectively. Delayed pupation and body size reduction of the mosquitoesfed with C. vulgaris, Chlorococcum sp. and S. quadricaudawere observed. In contrast, larvae fed with A. convolutus werebigger than those fed with normal insectory feed. The study showed thatC. vulgaris, S. quadricauda and Chlorococcum sp. have potentialto be used as larvicidal agents. |
