The presence of the insect stops chestnuts growing and the plague could, at worst, destroy the area’s €10 million crop.

Yesterday, April 22, the Andalucia Junta convened with local farmers to begin formulating a strategy to fight the appearance of eggs which grow in the crop and prevent proper growth.

The picturesque mountain settlements of Igualeja, Parauta and Pujerra have all reported the presence of the insect – Dryocosmus kuriphilus to scientists – and it is likely to spread.

The only known solution, favoured by the PP party and already being set in motion by the Junta, is to introduce a predator which hunts the gall wasp.
