Asian long-horned beetle

The Asian long-horned beetle(Anoplophora glabripennis), sometimes called Starry Sky (Sky Oxen in China) beetle, is native to China and where it causes widespread mortality of poplar, willow, elm, and maple throughout vast areas of eastern Asia. Asian longhorned beetles are big, showy insects: shiny and coal black with white spots. Adults are about 1 inch (2.5 cm) long. On their head is a pair of very long antennae that are alternately ringed in black and white. The antennae are longer than the insect's body. An invasive species in the United States, the larva of this beetle has a voracious appetite for wood. It is especially damaging to maple trees: Norway, sugar, silver, and red maple are among its preferred foods. The species also feeds on horse-chestnut, poplar, willow, and elm. Females of this species chew into the bark and lay eggs. When the eggs hatch, the immature beetles, which look like big white worms, chew their way farther into the tree. When they mature, the full-grown beetles chew their way out of the tree. The beetle life cycle leaves trees riddled with holes, oozing sap. The USDA believes this beetle can probably survive and reproduce in most sections of the country where suitable host trees exist. The beetle has also invaded Britain, Austria and Germany.

A serious pest of hardwood trees in its native China that by 1998 had been found in 14 states in the United States, where it has no known natural enemies. APHIS is now working to detect and destroy the beetle, which is virtually impossible to eradicate with pesticides because it bores deep inside trees to lay its eggs; the only known suppression method is to remove and destroy infected trees. The agency reports that the beetle, which already has led to the destruction of many trees in parts of New York, could destroy millions of acres of hardwoods—including maples, horse chestnuts, poplars, willows, and elms—if it becomes established in the environment. APHIS believes that the beetle has been entering the United States in solid wood packing materials such as pallets and crates from China. For that reason, in late 1998, it banned all shipments from China containing such packing materials if they have not been treated to kill the pest.
