ResumoMosquito larvicidal and repellent activities of phenolic acids of Chaetomorpha antennina (Bory) Kuetz. against the third instar larvae of Aedes aegypti were investigated. The larval mortality was observed after 24 h exposure. Results of mosquito larvicidal tests revealed that insoluble bound phenolic acids and soluble conjugated phenolic acid fractions of C. antennina had an exCellent inhibitory effect against A. aegypti and its LC50 values were 23.4 and 44.6 ?g ml?1, respectively. The repellency assay of insoluble bound phenolic acids and soluble conjugated phenolic acid fractions of C. antennina, at 10 ?g cm?2 concentration gave 100% protection up to 120 min. The results indicate that phenolic acids of C. antennina have a wide spectrum of larvicidal and repellent activities against Aedes aegypti.
