1,8-Cineole: An attractant for the banana weevil, Cosmopolites sordidus

Phytochemistry, 1996
1,8-Cineole was identified as one of the electrophysiologically active components of the volatiles from banana cultivars susceptible to the banana weevil. It was also shown to be an attractant for the banana weevil Comopolites sordidus in laboratory behavioural bioassays. The resistant cultivar did not contain 1,8-cineole.
