Non-native longhorned beetles are easily transported around the world in solid wood packing material, arriving in a new location with no natural enemies to control their populations. Across the country, many of these non-native beetles, particularly the Asian longhorned beetle, have killed tens of thousands of hardwood trees, especially in eastern states.
Will these pests ravage trees in Southeast Alaska? U.S. Forest Service specialists are working to determine ways to prevent the kind of devastation they’ve had elsewhere. Read more »

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 emerald ash borer and the Asian longhorned beetle, 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 Robert Haack, a research entomologist with the Forest Service’s Northern Research Station 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. Read more »
Retiring APHIS State Plant Health Director for Massachusetts, Connecticut and Rhode Island Patty Douglass inspects ALB damaged wood in Massachusetts.
One of the things I consider a highlight of my career and that I will always remember is our successful response to the July 2010 detection of the Asian longhorned beetle (ALB) in Boston, Massachusetts. As I attended the May 12 ceremony commemorating the eradication of the ALB infestation in Boston and listened to the speakers share their thoughts about what it took to get us there, I had a deep sense of appreciation for the partnership among the state and federal cooperators who worked together to bring us to that day. It was swift action and continued diligence that protected Boston’s trees from further destruction.
APHIS and its cooperators were able to accomplish the goal of eradicating ALB in Boston in less than 4 years. Thanks also go to a community member who reported the infestation early. That early detection and report resulted in the loss of only 6 infested trees.
But as I celebrate our first victory over the invasive pest in Massachusetts, I am compelled to ask you to remain vigilant in inspecting your trees regularly for signs of the beetle and report any suspicious damage to your State Plant Health Director. Read more »
At the APHIS Otis Lab in Massachusetts, employees conduct research for several APHIS forest pest emergency response and eradication programs, including Asian longhorned beetle (ALB), Asian gypsy moth (AGM), emerald ash borer (EAB), and Sirex noctilio woodwasp.
In addition to the existing science-based eradication protocols for fighting an Asian longhorned beetle (ALB) infestation, such as surveying trees and removing infested ones, the USDA’s Animal and Plant Health Inspection Service (APHIS) relies on on-going research to not only improve current protocols, but also to develop new ones.
APHIS’s Center for Plant Health Science and Technology continues research to develop attractant-baited traps designed to lure and capture adult insects. The attractants include plant odors and pheromones, which are naturally occurring chemicals created and used by insects to communicate with each other. These attractants are used to lure beetles to traps that are hung on trees that the beetle will attack. Traps can aid in early detection of insects in areas where survey staff may not be working. When the traps are checked by staff members and a beetle is found, nearby trees may be surveyed to determine if they are infested. This year, the traps will be placed in the spring and early summer in strategic locations in all three ALB-affected states: New York, Massachusetts, and Ohio. APHIS is also working with the U.S. Forest Service and Penn State University on their research with similar ALB traps. Read more »

Big, creepy, and horned, the coconut rhinoceros beetle (CRB) loves to feed on—and kill—coconut and other palms, banana plants, and more. This invasive species, detected in Hawaii in December 2013, makes the perfect poster child for USDA’s Invasive Plant Pest and Disease Awareness Month—a child only its mother could love.
How did it get here? And how can we prevent the spread of damaging, invasive species like this unwanted, oversized beetle? These are great questions to consider as USDA kicks off Invasive Plant Pest and Disease Awareness Month. Throughout April, we’re raising public awareness about the threat of invasive species and informing people how to prevent their spread—so we’ll face fewer surprises like the CRB. Read more »
Two Asian longhorned beetles on maple tree
Today is National Maple Syrup Day! So, what does maple syrup have in common with an invasive insect? Well, if the insect is the Asian longhorned beetle, then they both can come from maple trees. Obviously, we want the maple syrup and not the invasive beetle. But who cares? And why should anyone care? Well, I care and here’s why:
Not only do I work for the USDA’s Animal and Plant Health Inspection Service, an agency that is actively fighting known infestations of Asian longhorned beetle in three different states, but I also am a native of Vermont. Read more »
