Abstract
Heartwood aqueous extracts from Enterolobium cyclocarpum (Jacq.) Griseb. exhibited chronic toxic lethaleffect against Incisitermes marginipennis (Latreille) with more than 60% mortality at a concentration of 56.63mg. Feeding rate correlated positively with the mortality of termites. The termite hindgut cellulolytic activity,the symbiotic microorganism population in termite hindgut and fungal cellulase activity were not inhibited bythe aqueous extract. Two major chemical groups were detected in aqueous extract by gas chromatography; theywere monoterpenes (46.5%) and phenols (18.7%). Fifty seven constituents, including, D-limonene, terpineoland eugenol were identified; these terpenes have repellent activity against insects. These results suggest thatessential oils from E. cyclocarpum contain a slow acting toxin with a dissuasive effect on termites.

Key words: Enterolobium cyclocarpum, Hindgut, Antitermite activity
