Development of an operationally effective trap has been a goal of the Asian longhorned beetle (ALB) eradication program since the first individual ALB was found in New York in 1996. A trap that can demonstrate the presence of the ALB in an area is critical to detecting and eliminating infestations. A trap that is capable of detecting ALB at low densities in quarantine zones can also provide positive confirmation of successful eradication. NRS scientist Melody Keena was part of an interagency and university effort that developed the traps for ALB. In 2009, traps hung in trees in Worcester, MA, in areas where infested trees were still suspected to exist, caught female Asian longhorned beetles when baited with male-produced pheromones alone or in combination with plant volatiles. In 2010, the traps are being deployed in both the Worcester, MA, and Brooklyn/Queens, NY, infestations to assist in pinpointing lingering populations of ALB and in combination with fungal bands for an attract and kill strategy lead by researchers from Cornell University. In the future, the traps could also be deployed in high-risk areas in other states to detect new infestations.
