Mitigation of Invasive and High-Risk Wood-Boring Insects in China
Northern Research Station scientists are working with USDA and Chinese researchers to evaluate the risk of certain Asian wood boring insect species to attack non-native trees planted in China for landscape plantings, timber production, and reforestation. Many of these non-native tree species are more susceptible to attack by Asian woodborers, resulting in salvage of dying trees for production of solid-wood packaging materials, thereby increasing the risk of introducing Asian wood-boring insects into the U.S. from China, a key trading partner. To identify insects at high risk of introduction into the U.S., these scientists are studying the susceptibility of Asian native and non-native tree species in China to local wood-boring insects. In 2013, we discovered a wood-boring beetle that aggressively attacks and kills non-native poplar trees planted in China. This beetle is a close relative of the emerald ash borer, which is causing widespread mortality of ash trees in North America since its accidental introduction during the 1990s. We are now studying this wood-boring beetle as a high-risk invasive pest of poplar, and its possible management should it be accidentally introduced to the U.S.
