Ambrosia beetle plague threatens crops on the Granada Coast

The ambrosia beetle (Euwallacea fornicatus), previously unknown to farmers in the Costa Tropical — a coastal region in the province of Granada, Spain, renowned for its agricultural production — has become a serious threat after its presence was detected on three farms in Motril, the region's main agricultural hub. The Ministry of Agriculture has officially declared the infestation a plague, also recognizing the fungus associated with this insect as part of the threat.

According to the Official Gazette of the Government of Andalusia (BOJA), the infested area includes three plots within the urban area of Motril and surrounding areas, along with a one-kilometer buffer zone. The plague not only impacts avocado crops but also key produce like mangoes and custard apples, raising significant concern among farmers. However, the origin of the outbreak remains unknown, with experts exploring several unconfirmed hypotheses about how it arrived in the region.

Mandatory measures have been established to halt the spread:

1. Monthly inspections in affected areas.
2. Immediate pruning of infested branches and sealing wounds with a healing paste.
3. Removal and destruction of severely affected trees within 20 days.

Additionally, sharing tools, vehicles, and fruit containers without proper disinfection is strictly prohibited.

Previous actions and current situation

Since October 2023, 20 traps have been installed in Motril and five in forested areas to monitor the pest. Despite these efforts, the plague has spread, affecting ornamental trees, avocado crops, and expanding to nearby municipalities.

Farmers are awaiting compensation guidelines for those who must prune or remove trees. Meanwhile, authorities are intensifying efforts to contain this threat, which jeopardizes the agricultural production of the Costa Tropical.
