Field tests were conducted within the Ozark-St Francis National Forest to evaluate flight and landing behavior of red oak borer, Enaphalodes rufulus (Haldeman). Passive flight intercept traps were hung at various levels up to the canopy to determine preferred flight height of adult red oak borers. Clear plexi-glass passive traps were attached to tree boles to assess landing preferences on different tree species and on a single tree species. Preferential landing on suitable host trees indicate an attractant, either chemical or visual, while landing on non-host trees indicates a random flight and landing pattern with host evaluation occurring tactilely after landing. Northern red oak, Quercus rubra L., the tree species currently experiencing elevated mortality, was further assessed based on different red oak borer infestation levels. Results will be discussed and we believe these findings will give insight into the biology and behavior of Cerambycid species as well as facilitating the development of successful trapping methods.
