The document summarizes several common tree pests including the Asian Long Horn Beetle, Emerald Ash Borer, Gypsy Moth, and Western Pine Beetle. It notes that the Asian Long Horn Beetle was transported to the United States in infested packing material from China, the Emerald Ash Borer has killed over 20 million trees in several Midwestern states, and the Gypsy Moth was first introduced in 1870 and its larvae can fully defoliate trees. It also briefly outlines that the Western Pine Beetle primarily affects ponderosa and coulter pine trees in western states.
