The relationship between the Trade Volume to be inspected (TV) and the number of alien insect interceptions at Europe’s borders on agricultural imports (2003–2007), by A) country of origin (r = 0.02, n = 146, p = 0.810), B) commodity type (r = −0.01, n = 126, p = 0.910), C) alien insect species (r = 0.23, n = 116, p = 0.013) and D) European importing countries (positive correlation, r = 0.73, n = 28, p = 0.00001). Only the top 25 data points by TV and number of interceptions are displayed. Notes: B) +see Table S5 for full FAO commodity names.
