Technical Abstract: A semiochemical-based attractant for the Diaprepes root weevil has been sought since introduction of this polyphagous pest to Florida in the 1960s. Recent progress includes the identification of a set of putative kairomones consisting of common plant volatiles, a hypothetical aggregation pheromone that induces arrestment behavior as shown in wind tunnel experiments, and a putative pheromone of unknown function isolated by GC-EAD. A synthesis of current knowlegde of semiochemical-mediated communication in this species is presented.
