Wood boring insects are most often associated with dying or injured trees. Major wildfires over the past four years in the Black Hills of South Dakota have led to an increase in wood borer populations. In order to extend our knowledge of wood boring insect chemical ecology in the Black Hills, we initiated studies to develop trapping techniques to monitor wood borer populations and provide information on the guild of species associated with fire in ponderosa pine ecosystems. Two trap types and four different chemical attractants were selected and placed in the Roger’s Shack fire area. From May 30, 2003 through September 26, 2003 we collected 16 cerambycid species, 13 buprestid species and 5 siricid species. Results after one summer indicate that chemical attractants significantly attract more insects than control treatments. Results also indicate trap catch differences between chemical attractants. Research in the summer of 2004 again focused on chemical attractants and trap types, as well as examined under bark densities of larva in different fire severity and different age fires.
