What Trees are Attacked?: Trees favored by the Asian longhorned beetle are predominantly maples, but infestations have also been discovered in horsechestnuts, poplars, willows, elms, mulberries and black locusts. Currently, there is no known chemical or biological defense against the Asian Longhorned Beetle and, in North America, they have few natural predators.
How are Trees Killed?: The Asian longhorned beetle is a black insect with white speckles that grows a long antennae. The beetle chews its way into hardwood trees to lay eggs. The eggs produce larvae and those larvae tunnel deep under the bark and feed on living tree tissue. This feeding effectively cuts off the tree's food supply and starves it to the point of death.
Prevention: Unfortunately there are no methods developed to prevent or control Asian longhorned beetle. If you detect the presence of ALB, the only thing that will help is to contact local forestry officials. They can takes steps to contain the outbreak.
The only way currently known to combat the Asian Longhorned Beetle is to destroy the infested trees. While cutting down mature trees is a tragedy, it is preferable to permitting the Asian longhorned beetle to spread.
