説明

An oviposition stimulant of the azuki bean weevil Callosobruchus chinensis was isolated from aqueous extracts of its host, the azuki bean Vigna angularis. The kairomone was identified as D-catechin, (2S, 3S)-3, 5, 7, 3′, 4′-pentahydroxyflavan. It was active at 0.2-2ng per glass bead and was located only in the seed coat. A bean (average weight 136mg) contained 17.6μg of the compound. The fact that the purified D-catechin fraction was somewhat more active than commercially available D-catechin suggested the presence of other components of the kairomone or its synergist.
