Tiger mosquito detected for the first time on La Gomera in Valle Gran Rey
The Canary Islands Health Ministry detected adult specimens and larvae of Aedes albopictus in Valle Gran Rey for the first time. The ministry activated the entomological monitoring system.

The Canary Islands Health Ministry (Consejería de Sanidad) confirmed the presence of Aedes albopictus on La Gomera. The specimens were found at a finca in Valle Gran Rey near a barranco mouth. The General Directorate of Public Health (Dirección General de Salud Pública) activated the entomological monitoring system across the Canary Islands.
The detection followed a citizen report about small mosquitoes and frequent bites. Staff from the Institute of Tropical and Public Health Urology of the Canary Islands (IUETSPC) identified larvae and adults. Evidence suggests accidental introduction via material capable of transporting eggs.
Teams have deployed traps and are conducting inspections. Work will continue for the coming days. Potential breeding sites are being located and eliminated. Information is being shared with residents, businesses, and institutions in the area.
The Health Ministry stated that bites were reported only at the source location. The presence of this species does not automatically mean transmission of diseases such as dengue, Zika, yellow fever, or chikungunya.
