ABSTRACT Activity guided isolation of the crude ethanol extract of the leaves and stems of Bonita daphnoides using adult Cylas formicarius as the test organism revealed that the most insecticidally active compound was the sesquiterpene furan, epingaione. This compound was previously isolated and characterized by Chinnock et al., (1987). The 72 hour Lc50 values (?g/insect) found for the furan was 20.80 (17.34-24.52), while the values obtained for a nicotine rich extract of tobacco and a commercial organophosphate insecticide, dimethoate were 32.00 (28.15 � 40.32) and 9.54 (8.40 � 10.62) ?g/insect, respectively. 56
