Low Heat Availability Could Limit the Potential Spread of the Emerald Ash Borer to Northern Europe (Prognosis Based on Growing Degree Days per Year)

Orlova-Bienkowskaja MJ, Bieńkowski AO (2022) Low Heat Availability Could Limit the Potential Spread of the Emerald Ash Borer to Northern Europe (Prognosis Based on Growing Degree Days per Year). Insects 13(1):52. https://doi.org/10.3390/insects13010052 


Emerald ash borer Agrilus planipennis (Coleoptera: Buprestidae) is one of 20 priority quarantine pests of the European Union. It is native to Asia and is established in the USA, Canada, European Russia, and Ukraine. We made the first prognosis of the potential range of A. planipennis in Europe based on heat availability. Mean annual growing degree days base 10 °C (AGDD10) was calculated for each grid square (0.25° × 0.25° latitude x longitude degrees) on the Earth’s surface. Minimal AGDD10 recorded in the grid squares currently occupied by A. planipennis was 714° in Asia, 705° in North America, and 711° in European Russia. Agrilus planipennis has never been recorded in localities with AGDD10 below 700°. If the phenotypic plasticity would not allow this species to overcome this threshold, cold regions of Europe would probably not be invaded by A. planipennis. Thus, Fraxinus excelsior could potentially escape from A. planipennis in some regions of Norway, Sweden, Finland, Ireland, and Great Britain.
