Abstract Behavioral bioassays have confirmed that the oviposition-deterring secretion of the cabbage seed weevil, Ceutorhynchus assimilis Payk., can be isolated from glass tubes marked by the weevil and from extracts of its dissected seventh urotergite. Analysis of the secretion by gas chromatography—mass spectrometry showed that it contained iso- and n-alkanes, dimethylalkanes, alkenes, fatty acids, 15-nonacosanonc, 15-nonacosanol, and cholesterol. The oviposition-deterring properties of the secretion are associated with a more polar traction, isolated by liquid chromatography front an extract of the seventh urotergite.
