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

摘要

The effect of four microalgal chlorophytes, Chlorella vulgaris, Scenedesmus quadricauda, Chlorococcum sp. and Ankistrodesmus convolutus, on the survival, larval development and adult body 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 mosquitoes fed with C vulgaris, Chlorococcum sp. and S. quadricauda were observed. In contrast, larvae fed with A. convolutus were bigger than those fed with normal insectory feed. The study showed that C. vulgaris, S. quadricauda and Chlorococcum sp. have potential to be used as larvicidal agents.
