About the Citrus Longhorn Beetle

Anoplophora chinensis, the citrus long-horned beetle (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.

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.

Anoplophora chinensis is native to most parts of China and Korea, as well as Vietnam, Malaysia, Indonesia, and the Philippines. However, this beetle is characterized as an invasive species in many parts of the world, including countries in Europe such as Italy, as it has been able to be transported to additional geographic regions by burrowing into shipments from Asia to countries in Europe. It makes its way into shipments that contain plants or wood and burrows into them.

The citrus long-horned beetle was first discovered in the U.S. in April 1999... Wikipedia →
