Journal of American Science, 6(10), 435 - 4401545-1003https://repository.futo.edu.ng/handle/20.500.14562/1832This article contains tables and figures.The activities of ethanol extracts of A. indica, O. gratissimium and C. citratus on Ae. aegypti larvae were investigated at 96 hours exposure. Mortalities were observed to increase with concentration (P  0.05).The larvae of Ae. aegypti exhibited differential susceptibility to the extracts of the three plants.. In C. citratrus, mortality was recorded all through the exposure period of 96hours comparing to A. indica and O. gratissimum in which activities ceased at 48 hours. Comparative evaluation of the LC50 of three plant extracts showed significantly high toxicities with A indica showing the greatest toxicity having LC50 at 8.32mg/ml, while on the other hand O. gratissimum and C. citratus had LC50 19.50mg/ml and 34.67mg/ml on Aedes aegypti respectively. There were also variations in the composition of the phytochemicals in the 3 plants with A. indica having highest amount of all the phytohemicals relative to other plants except flavonoids, while glycosides were completely absent in the 3 plantsenAttribution-NonCommercial-ShareAlike 4.0 InternationalAedes aegyptiextractlarvaeethanolmosquitoplantDepartment of BiotechnologyArticle
