Each female citrus long-horned beetle can make up to 200 eggs after mating, and each egg is separately deposited in tree bark. CLHB takes approximately one year to complete its development (CABI 2004, Lieu 1945). Prior to the localized Washington population, a single adult CLHB was intercepted in 1999 at a nursery in Athens, Georgia, on a shipment of crepe myrtle (Lagerstroemia) bonsai from China (Thomas 2004).

As of 2005 there were no reports of new infestation (2005 Updates). The tree injection has been a successful component of the Asian longhorned beetle eradication program and imidacloprid was recommended for use during the eradication program for CLHB (WSDA 2002, Anonymous 2002b). (2002). Citrus longhorn beetle can attack a very wide range of deciduous tree and shrub species, including several species native to the UK. Eggs are deposited under the bark through a T-shaped oviposition slit made at the base of the trunk or exposed roots. Although adults do feed on leaves, and bark of twigs, the damage is usually not considered severe. During its later instars, the larva makes irregular tunnels in the wood, and continue to do so until pupation. Revision of. It is a pest of major concern for citrus growers in parts of China. USDA.

The first infestation of citrus longhorned beetles was discovered in 2001 on quarantined, imported maple trees in a plant nursery in Tukwila, Washington (Anonymous, 2002). Attacked trees will eventually die. The base of the elytra has numerous short processes (tubercles) called granulae, a morphological character that may help to differentiate CLHB from the Asian longhorned beetle, Anoplophora glabripennis. European Network on Invasive Alien Species. In North America, except for interceptions at various ports of entry, there were no records of established populations until local infestations were detected for the first time in Tukwila, Washington on maple trees (Acer) imported from Korea (Grob 2003, Lingafelter and Hoebeke 2002).

Exit hole created by the emergence of an adult citrus longhorned beetle, Anoplophora chinensis (Forster). The majority of damage associated with CLHB is caused by the larval stages which feeds and tunnels on the woody portion of the host plant trunk. The beetle chews its way into hardwood trees to lay eggs. Citrus long-horned beetle females lay 200 eggs, each. The beetle can launch itself as far as 400 meters, in search for a tree to lay eggs in. Canadian Food Inspection Agency. Other signs include round holes on the trunk of a tree, exposed roots and sawdust-like frass or wood pulp around exit holes at the tree’s base.
