A highly invasive wood-boring beetle was intercepted last month by U.S. border agents before it could destroy forests and ecosystems, Customs and Border Protection announced Monday. The live Asian long-horned beetle, which can cause significant damage to hardwood trees, was discovered during an inspection of wood cargo from Romania on March 17. CBP agriculture specialists at the Port Huron rail yard in Michigan found solid insect waste before discovering live beetle larvae. …The beetle larvae were found inside wood pallets that were stamped with a marking to show that they had been heat-treated to prevent invasive species. The treatment is required by the Interim Commission on Phytosanitary Measures of the International Plant Protection Convention and is the international standard for the safe use of wooden pallets and crates. While the marking on the wood packaging material “appeared to be legitimate,” agents believe the heat treatment process may not have been “executed properly.”
