Developing epidemiological preparedness for a plant disease invasion: Modelling citrus huánglóngbìng in the European Union

PLANTS, PEOPLE, PLANET, Volume 7, Issue 5, Page 1403-1423, September 2025.
Huánglóngbìng (HLB) is a bacterial disease of citrus that has significantly impacted Brazil and the United States, although citrus production in the Mediterranean Basin remains unaffected.
