Effect of trap design, trap height, and habitat on the capture of sap beetles (Coleoptera: Nitidulidae) using whole-wheat bread dough

Nine trap designs were compared for capturing sap beetles: Lindgren funnel, Multi-Pher I, Skalbeck, Unitrap, Japanese beetle, liquid, water pan, cone, and McPhail. The Lindgren funnel was most effective for Glischrochilus fasciatus (Olivier) and G. quadrisignatus (Say). The Lindgren funnel, Multi-Pher, Skalbeck, moth, and liquid trap all caught equal numbers of Carpophilus lugubris Murray. The Skalbeck is recommended because of its low cost. G. fasciatus, G. quadrisignatus, and C. lugubris flew to higher traps in apple orchards than in open grassy areas
