Resumo: To determine the adulticidal activity of hexane, benzene, chloroform, and methanol leaf and seed extracts of Delonix elata (D. elata) against Aedes aegypti (Ae. aegypti).Methods: The bioassay was conducted in an experimental kit consisting of two cylindrical plastic tubes both measuring 125 mm x 44 mm following the WHO method; mortality of the mosquitoes was recorded after 24 h.Results: The adulticidal activity of plant leaf and seed extracts showed moderate toxic effect on the adult mosquitoes after 24 h of exposure period. However, the highest adulticidal activity was observed in the leaf methanol extract of D. elata against Ae. aegypti with the LC50 and LC90 values 162.87 and 309.32 mg/L, respectively.Conclusions: From this result, it can be concluded the crude extract of D. elata was an excellent potential for controlling Ae. aegypti mosquitoes.
