Tiger mosquito detected for first time in La Gomera

The Canary Islands Health Department has activated the Entomological Surveillance System following the first detection of the tiger mosquito (Aedes albopictus) on the island of La Gomera. Adult specimens and larvae were identified at a property located near the mouth of the Valle Gran Rey ravine.

The discovery followed a citizen alert regarding small mosquitoes and frequent bites in the area. Researchers from the University of La Laguna's Institute of Tropical Diseases and Public Health confirmed the species through laboratory analysis. Initial evidence suggests the mosquito was introduced accidentally via materials capable of carrying eggs.

Health authorities have deployed traps and are conducting inspections to determine the extent of the presence. Measures include identifying and eliminating breeding sites, as well as cleaning and fumigation efforts by the Valle Gran Rey City Council. While the species is known to carry diseases such as dengue, Zika, yellow fever, and chikungunya, officials noted that the current presence does not imply any disease transmission.
