Comparison of lure-baited insecticide-treated tripod trap logs and lure-baited traps for control of Ips duplicatus (Coleoptera: Curculionidae)
Journal of Pest Science 86 (3), 483-489
Abstract: Two methods were compared for capturing the bark beetle Ips duplicatus Sahlberg (Coleoptera: Curculionidae, Scolytinae): lure-baited, insecticide-treated tripod trap logs (TRIPODs) versus Theysohn pheromone traps (TPTs). In 2008 and 2011 and at each of three clearcuts, five TPTs and five TRIPODs baited with ID Ecolure pheromone evaporators were installed with 10 m spacing. The pheromone evaporators were renewed every 8 weeks. The TRIPODs were treated with the insecticide Vaztak 10 EC in mid-April and then every 5 weeks thereafter. Trap logs and traps were inspected weekly during the entire period of I. duplicatus flight activity (April-September). Two to three times more beetles were trapped by the TPTs than by the TRIPODs. The TPTs captured more females than males, while TRIPODs captured equivalent numbers of males and females or more males than females on some dates. The TPTs and TRIPODs trapped approximately the same numbers of males, but the TPTs captured more females than the TRIPODs. Both traps captured more adults in spring than in summer. The higher numbers of entomophagous arthropods, including the predacious beetles Thanasimus formicarius L. and T. femoralis, were captured in the TRIPODs than in the TPTs.
