(±)-des-N-morphinan: a unique bridged hydrocarbon attractant for the rhinoceros beetle, Oryctes rhinoceros; and development of an olfactometer

Abstract

An olfactometer designed for Oryctes rhinoceros (L.) is described and its effectiveness demonstrated by a comparison of results with field tested chemicals. Using the olfactometer, (±)-Des-N-morphinan, but not its stereoisomer was found to be a strong attractant for adult rhinoceros beetles. This is the 1st synthetic bridged hydrocarbon found to be an insect attractant
