This research is conducted to evaluate the efficacy of cossia fistula L. (Golden shower) funiculus and pericarp extracts using 95% ethanol as solvent against different Aedes rs. The funiculus extract from c fistula were used to control A. aegypti larvae, the 4 nstar larvae. The result showed that LCso of funiculus extracts at 24 hours and 48 hours were and Lcsoof perlearp extracts at 24 hours and 48 hours were 4.162% and 1.931% v/v. So, funiculus extract was selected to compare efficiency with 0.01% (ww) Abate on mortality of worst effective solution. The o 4 0.9% ww of funiculus extracts were the best group. Lc of the funtculus extracts to A. oegypti pupae at 24 hours and 48 hours were 0.303% and chemical from Abate
