Efficacy of synthetic Limonius sex pheromone on trap captures of four Limonius spp. (Coleoptera: Elateridae) in various locations across North America

Student Competition On-Demand
Wireworms, the larval form of click beetles (Elateridae), are significant agricultural pests of cereals, potato, corn, vegetable, sugarcane, and other crops.  With pest populations on the rise throughout Europe and North America, and control options limited, there is an ever-increasing need to develop novel, earth-friendly monitoring and control tactics. Pheromone-based monitoring of elaterid populations would reveal their geographic distribution and local abundance, help predict crop damage, and time insecticidal control measures. In Europe, female sex pheromones of most economically important click beetle species have been identified and are currently used to survey for the presence and abundance of species. In North America, pheromone research on important click beetle species is underway and has recently resulted in the identification of the (long elusive) sex pheromone of female Pacific Coast wireworms (Limonius canus LeConte) and female sugarbeet wireworm (L. californicus Mann.). Here, we report on the efficacy of synthetic Limonius sex pheromone on captures of the four dominant Limonius pests in various locations across North America: L. canus, L. californicus, L. infuscatus, and L. agonus.
