Abstract

We evaluated the relative efficacy of six pheromone-baited traps used in trapping Agriotes obscurus (L.) click beetles (Coleoptera: Elateridae): original Yatlor Traps, Yatlor Funnel Traps, Vernon Beetle Traps, Unitraps, Baited Pitfall Traps, and Vernon Pitfall Traps. Traps were rated according to quantitative and qualitative criteria of importance for each of four trap uses: general surveys, scientific studies, IPM monitoring, and mass trapping. Measurable quantitative categories included: total catch of A. obscurus; time for assembly, installation, and inspection; exclusion of nontarget invertebrates; and cost. Qualitative criteria were small mammal exclusion, flooding, design and handling variability, and convenience for various field uses. The most desirable characteristics were determined for the above four uses, and the cumulative ranking based on quantitative criteria and all four uses was Vernon Pitfall Trap, Baited Pitfall Trap, Original Yatlor Trap, Vernon Beetle Trap, Yatlor Funnel Trap, and Unitrap.
