【Aim】 To understand quarantine-scale pests intercepted at ports in China and provide a reference for further plant quarantine at ports. 【Method】 Data on intercepted scale pests at ports from 2010 to 2019 were collected, cleaned, and classified, and the variation in species, time, quantity, host, and origin of intercepted scale pests were statistically analyzed. 【Result】 From 2010 to 2019, 24541 quarantine-scale pests were intercepted in China, and the annual intercepted species showed an upward trend. Twelve quarantine-listed pests were intercepted, three of which were Ceroplastes rusci, Hemiberlesia pitysophila, and Phenacoccus solenopsis. The three most intercepted customs areas were Shenzhen, Nanning, and Shanghai Customs. Inspection of goods was the main interception route, and the main hosts were Durio zibethinus, Musa paradisiaca, Nephelium lappaceum, and Annona squamosa. The intercepted sources were from 49 countries or regions from all continents, except Antarctica, of which Southeast Asia was the most important source, and Thailand, Vietnam, and Philippine were the main source countries. 【Conclusion】 The interception of scale insects is closely related to the import fruit trade. Given the increasing trade volume, one should be alert to the risk of scale insects spreading into China. Improving quarantine management, detection ability, quarantine treatment, and block scale insects outside the country is imperative.
