Rapid Pest Risk Analysis for Diabrotica speciosa (Germar)


This is a polyphagous pest which has never been intercepted entering the UK. It has only been intercepted entering the EU on one occasion. The most likely sources of D. speciosa entering the UK are: cut flowers, fruit, vegetables and plants for planting with soil arriving from South America. However, it is unlikely that D. speciosa will enter the UK and unlikely that it will establish if it does. If this species does establish briefly it is likely that this would only be in the South of England in a particularly warm year. The largest risk of crop damage would be larval damage to potatoes and it is unlikely to cause damage at an economic level. Eradication would be difficult if D. speciosa were to establish in the UK, however control measures are available and monitoring traps may be available soon.
