Abstract: Established populations of the pine shoot beetle, Tomicus piniperda (L.) (Coleoptera: Scolytidae), were first detected in the US in 1992. As of January 2000, T. piniperda was known to be established in 271 counties in 11 US states (IL, IN, MD, MI, NH, NY, OH, PA, VT, WI, WV) and 25 counties in Ontario and 8 counties in Quebec, Canada. In a 1998 study, we found that marked and released T. piniperda were captured in traps up to 400m outside of operational sawmills and simulated millyards despite the abundance of brood material present in the millyards; 400m was the furthest distance to which traps were placed in 1998. In 1999, we investigated T. piniperda's,/I> potential for longer range dispersal in the absence of suitable breeding material. In this study, traps were placed out to 2 km in an open agricultural field. Marked and released beetles were captured up to 800m from a central release point. In a companion study conducted in Geneva, New York by Al Barak (USDA APHIS, OTIS) marked and released T.pinipera adults were recaptured up to 2km from the release point. Such studies indicate that T.piniperda is capable of long distance flight and that adults could be carried even further by strong winds.
