Wood makes great packaging material—it’s inexpensive, abundant and versatile—but there’s one drawback: destructive forest pests stowaway in the pallets, crates and dunnage (wood used to brace cargo) used in international shipping. Over many years, international trade has resulted in the inadvertent introduction of many non-native wood-feeding pests and plant pathogens in the U.S. and throughout the world. Some of these non-native insects, including the and the , have become highly invasive and caused serious environmental and economic impacts.
But an international standard for wood packaging material is slowing the inadvertent export of invasive bark- and wood-boring insects, according to a study conducted by , a research entomologist with the in Lansing, Mich., and a team of scientists. Researchers found as much as a 52 percent drop in infestation rates in the U.S., where the standard was implemented in three phases between 2005 and 2006. The study was published May 14 in the journal PLOS ONE.
