Semiochemicals and Diaprepes abbreviatus (Coleoptera: Curculionidae) behavior: implications for survey

The existence of semiochemicals that influence reproductive behavior in the West Indian sugarcane root stalk borer weevil, Diaprepes abbreviatus (L.) has been demonstrated. Semiochemicals are produced by both male and female weevils. The aggregation of weevils is interpreted as a pheromone-induced behavior and this specific attractant is produced by the male weevil. /// Se ha demonstrado la existencia de "semiochemicals" que influyen el compartamiento reproductivo de Diaprepes abbreviiatus (L.). "Semiochemicals" son producidos por los gorgojos machos y hembras. La agregación de gorgojos es interpretada como un comportamiento inducido por feromonas y que este específico atrayente es producido por el gorgojo macho.
