VOICED: Caterpillar attacks French trees

The video discusses the impact of the chestnut miner butterfly on chestnut trees in France. The insect lays eggs in leaves, causing premature leaf loss. Due to a warm spring, the butterflies emerged early, leading to a proliferation of larvae. These insects spread via transport and pose a threat to tree health, making them more susceptible to diseases. Control measures like insecticides are costly, and researchers are exploring natural predators like wasps. However, incineration of leaves is currently the most effective method. Authorities in Paris plan to burn leaves to protect the city's chestnut trees.
