Question 17047 — environment

Summary

Mr. Olivier Gaillard draws the attention of the Minister of Agriculture and Food to the damage linked to the proliferation of the box tree moth on French territory. The boxwood moth (Cydalima perspectalis), a parasitic butterfly native to Asia, is considered an invasive species. Feeding on leaves and young shoots, it gnaws the tree down to the bark, leaving the shrubs no time to regenerate. His Attacks cause severe defoliation which can be total in certain areas. Accidentally introduced into Europe in the 2000s, it is now widely present throughout Europe and in almost all French departments. Initially attacking private gardens and public parks, it proliferates uncontrolled, also impacting French forests. But boxwood plays a major role in the preservation of the forest ecosystem: its roots contribute to soil stability, and it is home to great biodiversity (insects, lichens, etc.). By threatening the survival of the boxwood, the insect now represents a threat to the biodiversity of the territory. In the Gard department, the boxwood moth has attacked numerous areas, causing significant damage. Given the uncontrolled nature of this proliferation and the damage thus generated, he asks what actions the Government intends to implement to stem this phenomenon and fight against this scourge.
