In order to further carry out pest risk analysis of European grains exported to China, this study collected the data intercepted from European grains exported to China from 2003 to 2017, used SPSS 20 software to carry out cluster analysis, correlation analysis and principal component analysis on the intercepted main pest weeds and insects, and determined the main factors controlling their interception times. The results showed that weeds were the main pests intercepted in grains exported from Europe, and the number of intercepted records was 7 905, accounting for 79.99% of the total intercepted records; the number of pests intercepted from barley exported to China from Europe was the highest (57 843 interceptions), accounting for 51.39% of the total interceptions; the numbers of weeds and insects intercepted from the grains exported to China from Ukraine were the highest (39 026 and 678 respectively); there were 479 species of weeds and 61 species of insects intercepted from grains exported to China from Europe; the Shannon-Weiner indexes of weeds and insects intercepted from Ukraine and barley were relatively high; the weeds and insects intercepted from barley and corn exported to China from Europe were grouped into one category separately, and the weeds and insects intercepted from grains exported to China from Ukraine and France were grouped into one category separately. The trade volume of European grains exported to China was the main factor controlling the interception times of weeds and insects. It suggested that China should improve the collection of pest interception data, strengthen the pest risk analysis of European grains exported to China, and take appropriate quarantine measures for different countries and grains according to their risks.
