Thousand cankers disease, caused by the walnut twig beetle (Pityophthorus juglandis Blackman) and an associated fungal pathogen (Geosmithia morbida M. Kolarík, E. Freeland, C. Utley, and N. Tisserat), threatens the health and commercial use of eastern black walnut (Juglans nigra L.), one of the most economically valuable tree species in the United States.(More)
Widespread infestation of soybeans with soybean aphid across much of Wisconsin during the 2000 growing season prompted us to examine the economic impact this insect poses to the soybean crop in terms of direct yield losses (the potential yield losses due to virus transmission by the aphid are not addressed here). The goal of this study is to examine the(More)

Global trade facilitates the inadvertent movement of insect pests and subsequent establishment of populations outside their native ranges. Despite phytosanitary measures, nonnative insects arrive at United States (U.S.) ports of entry as larvae in solid wood packaging material (SWPM). Identification of wood-boring larval insects is important for pest risk(More)
