Guangzhou, 18 Dec (China News Network) -- According to a report by the Guangdong Zhongshan Entry-Exit Inspection and Quarantine Bureau on 18 December, when the staff of the bureau inspected a batch of logs (iron beans) imported from Guyana on the shore of Zhongshan Port, they found that there were obvious worm holes in the logs, and after prying open, they found small beetle adults. After laboratory identification and expert review, it was determined that the insect was a rubber beetle, which was intercepted for the first time at Zhongshan Port. The bureau has carried out quarantine treatment of the entire batch of logs in a timely manner.
Rubber beetles are listed in China's "List of Quarantine Pests entering the country" and are widely harmful forest pests. Adults are 2.0–2.7 mm long and are difficult to see with the naked eye. The insect is mainly distributed in the eastern United States and most of the world's tropical and subtropical regions. At present, there is no record of the distribution of rubber beetles in China.

Rubber beetles mainly harm woody plants by drilling moths, lurking in the bark or wood center for life, and the damaged parts show needle cone borers and yellow-brown wood powder. In severe cases, the stem is covered with borer holes and powder columns and powder, so that the trees die. The insect has strong fecundity and can spread over long distances with logs, wooden packaging, etc. There are currently no effective prevention and control measures.
