EPPO Alert List – Anoplophora horsfieldii (Coleoptera: Cerambycidae)
Anoplophora horsfieldii (Coleoptera: Cerambycidae - chinaberry yellow-banded longhorn beetle) originates from South-East Asia. Its establishment on the island of Jeju (Republic of Korea) has recently been reported, thus indicating that this insect has the potential to expand its distribution range. On Jeju Island, the first specimens of A. horsfieldii were photographed in September 2019 in urban environments by members of the public. In July 2022, scientists observed adult beetles and exit holes in Celtis sinensis (Cannabaceae) trees. They confirmed the establishment of A. horsfieldii and estimated that the insect had been introduced around 2015. For the moment, the pest is restricted to a small area located between the island’s largest port and airport. Because of its possible similarities with other damaging and invasive Anoplophora species (i.e. Anoplophora chinensis and A. glabripennis), the EPPO Secretariat considered that A. horsfieldii could usefully be added to the EPPO Alert List.

Its known distribution is restricted to South-East Asia, and it has been proposed that A. horsfieldii could be separated into three subspecies occupying different geographical areas: A. horsfieldii horsfieldii (China), A. horsfieldii tonkinensis (Indochina) and A. horsfieldii taiwanensis (Taiwan). As explained above, A. horsfieldii has recently been introduced on Jeju Island in the Republic of Korea (absent from the mainland). An old record of the species in Assam (India) is considered doubtful.
EPPO region: Absent.
Asia: China (Anhui, Chongqing, Fujian, Gansu, Guangdong, Guangxi, Guizhou, Hainan, Henan, Hubei, Hunan, Jiangsu, Jiangxi, Shaanxi, Shanghai, Sichuan, Yunnan, Zhejiang), Korea (Republic of), Laos, Taiwan, Thailand, Vietnam.
On which plants: According to the literature, the known host range includes the following tree species: Azadirachta indica (chinaberry), Camellia oleifera (oil-seed camellia), Camellia sinensis (tea), Celtis sinensis (Chinese hackberry), Citrus sp., Quercus glauca, Ulmus pumila.
The main damage is caused by larvae which bore into the wood of living trees. External signs of infestation include circular exit holes (> 15 mm diameter), sawdust-like frass ejected from larval galleries, sap oozing from oviposition pits, adult maturation feeding on branches and shoots. On Jeju Island, it has been observed that attacked Celtis sinensis trees were totally or partially withered, but that external signs of infestation were far less evident than those of A. glabripennis or A. chinensis.
Adults of A. horsfieldii are large beetles (23-43 mm long), black or dark brown and shiny, with large yellow velvety patches distributed over the whole body. The antennae exceed three-quarters of the body length in males and are slightly longer than body length in females. As it is a large and beautiful insect, dead specimens can easily be found for sale online.
More pictures can be found on the Internet.
Adults can fly, but no information on their flying abilities could be found. In international trade, A. horsfieldii is likely to be moved on plants for planting and wood products of its host plant species. No records of interceptions made in the EPPO region could be found.
Plants for planting, wood of host plants from countries where A. horsfieldii occurs.
Information on many aspects of the biology, and in particular on the damage caused by A. horsfieldii in its native range, is generally missing in the available literature. However, past experience with the introduction of similar species in the EPPO region (i.e. A. chinensis and A. glabripennis) advises for caution.
