Complete Elimination
State and federal organizations that are involved with controlling the Asian longhorned beetle aim to totally eradicate this insect from North America. The Asian longhorned beetle originates from China, where it causes marked damage to trees. It was recognized by the American Science Advisory Panel in 1996 that this beetle is capable of attacking and destroying healthy trees and that the beetle will target hardwood trees throughout the United States.
Control Measures
Controlling the Asian longhorned beetle is very challenging. The Science Advisory Panel is concerned that biological control of this insect will not be able to suppress its population growth in the long-term. The Panel also believes that chemical control of the beetle is not viable in forested areas and that this means of control will not afford a short-term answer.
Removal of Infected Trees
Researchers are studying the biology of this insect pest, so that appropriate control measures can be implemented, but in 2011 the removal of infected trees appears to be the best means of control. Remove the stumps of infested trees to a depth of 8-inches below ground if you discover the beetle either on the tree's roots or on the bottom 2-feet of the tree's bole. The tree must subsequently be chipped and incinerated.
Research Projects
The U.S. Department of Agriculture has initiated studies to determine how best to eradicate the Asian longhorned beetle. Eradication is proving difficult and management strategies, such as the immediate removal of infested trees, are being put in place. Researchers are studying the effect of chemical insecticides. Although chemicals are not appropriate for application in maple forests, these insecticides may prove useful to contain the beetle and prevent its population from spreading even further. In 2011, laboratories are also carrying out studies to produce chemical attractants, such as pheromones, to trap these insects.
