Pheromone Bouquet of the Dried Bean Beetle, Acanthoscelides obtectus (Col.: Chrysomelidae), Now Complete (Eur. J. Org. Chem. 22/2015)
The cover picture shows a dried bean beetle, Acanthoscelides obtectus, on red beans with admirably round boreholes. Males produce a female-attracting sex pheromone (see gas chromatogram) consisting of methyl (2E,4Z,7Z)-2,4,7-decatrienoate (1), methyl (2E,4Z)-decadienoate (2), (3Z,6E)-α-farnesene (3), its (3E,6E) isomer (4), methyl (E,R)-2,4,5-tetradecatrienoate (5), and octadecanal (6). A blend of synthetic compounds in natural proportions, tested in biologically relevant amounts, was as attractive as the natural signal. These results will form the basis for the development of effective management tools against this economically important pest. Details are discussed in the article by M. A. Birkett et al. on 4843 ff.
