Large woodboring insects (Buprestidae, Cerambycidae, Elateridae, and Siricidae) are ecologically and/or economically important in the southeastern U.S. forests. Surveys are conducted annually in the region to monitor populations of native and exotic woodboring beetle species. My research objectives were as follows: 1) to assess the efficacy of various trapping techniques for surveying of native siricids (woodwasps) and their hymenopteran parasitoids in southeastern pine (Pinus spp.) stands; and 2) to determine the effect of lure placement on modified funnel traps on capturing efficiency of large woodboring beetles. Creating trap-logs at the peak flight of siricids (early November) and using fresh pine billets with an intercept panel trap were the most efficient methods for trapping native siricids and their hymenopteran parasitoids. A modified funnel trap with lures hanging on the inside of the trap maximized the catches and diversity of cerambycid and elaterid beetles.
