Abstract

The purpose of this study is to determine the larvicidal activities of ethanolic extracts from leaves, wood, and bark of black heartwood-type Cryptomeria japonica against fourth-instar larvae of mosquitoes Aedes aegypti and Aedes albopictus. Among three ethanolic extracts from C. japonica, wood extract exhibited the best larvicidal activity against A. aegypti and A. albopictus with LC₅₀ values of 63.2 and 93.8 μg/ml, respectively. Four major compounds, including ferruginol, epi-cubebol, cubebol, and isopimarol, were isolated from wood extract, and it was demonstrated that cubebol exhibited the best activity against A. aegypti and A. albopictus with LC₅₀ values of 60.1 and 50.0 μg/ml, respectively. Our findings showed that the wood extract and cubebol from C. japonica have good potential as a source for natural larvicides.
