Resumen:
The sugarcane stem weevil, Acrotomopus atropunctellus (Boheman) (Curculionidae:Molytinae: Cholini) is an important economic pest from the Northwestern region ofArgentina. Analyses of the headspace volatiles produced by separated males and females revealed one male-specific compound. Its structural identification is reported here in using gas chromatography coupled with mass spectroscopy analysis and chemical micro-reactions. Besides, two laboratory olfactometry assays allowed us to propose 6-methyl-5-hepten-2-one (sulcatone) as an aggregation pheromone forthis insect, being attractive to both conspecific males and females. This compoundis reported for the first time as involved in the Curculionidae family communication.
