The citrus long-horned beetle (Anoplophora chinensis, also appearing in many sources as Anoplophora malasiaca) is a long-horned beetle native to Japan, China, Korea, Taiwan and Southeast Asia where it is considered a serious pest. This beetle has invaded several countries in Europe, including Italy, Switzerland, Turkey, France, Germany, and Croatia.

Each female citrus long-horned beetle can lay up to 200 eggs after mating; each egg is individually deposited in tree bark. After the beetle larva hatches, it chews into the tree, forming a tunnel that is then used as a place for pupation. From egg-laying to pupation and adult emergence can take one to two years.

Infestations by the beetle can kill many different types of hardwood trees including Citrus, pecan, apple, Australian pine, Hibiscus, sycamore, willow, pear, mulberry, chinaberry, poplar, Litchi, kumquat, Japanese red cedar, oak, and Ficus.
