The Alcalá de Guadaíra City Council coordinates with Tragsa and the Provincial Council to monitor the Nile virus. The peri-urban traps recorded a low presence of mosquitoes, with only 50 specimens captured.
The Alcalá de Guadaíra City Council has taken a further step in its plan to prevent the West Nile virus. The delegate for Natural Monuments, Environment and Sustainability, Luisa Campos, held a coordination meeting with the technicians involved in mosquito monitoring and control, both from the council itself and from the Provincial Council of Seville.
Participants in the meeting included Conrado Peinado, Public Health agent; Juan Carlos Rosso, Environmental Health technician from AGS Sevilla Sur; Eduardo Rodríguez, from the company Athisa, a collaborator with the City Council; María Luisa Cabanillas, from the Provincial Council; and Roberto Muriel, from the Tragsa group, which works for the Provincial Council on this matter.
During the meeting, the actions carried out within the Municipal Vector Monitoring and Control Plan (PMVCV) were analysed. Outside the urban core, Tragsa reviews the inventoried larval points every two weeks and applies larvicidal treatment with BTI (Bacillus Thuringiensis Israelensis) when necessary. In the last review, the peri-urban traps detected only 50 mosquito specimens, a figure that indicates a low presence of the insect.
Within the urban area, the City Council has delineated up to 33 larval control points in its municipal plan. In the drains, it has been decided to apply BTI in those that show waterlogging. Additionally, the plan includes two BG traps with chemical attractants, with continuous sampling every 15 days that provide very low capture rates.
Luisa Campos explained that these efforts are carried out throughout the city and intensively in sensitive areas such as wetlands, the banks of the Guadaíra River, urban parks, and green areas. “In addition to these planning and control meetings, we carry out monitoring and prevention work throughout the year from the Delegation, to minimise mosquito breeding sites and reduce the risk to the population,” the delegate stated.

The City Council reports to the Official Control Reference of the VFNO the reports of actions with the diagnosis and, where applicable, the treatment of the delineated areas. Coordination between administrations is key to keeping the spread of the virus in check, which has caused health alerts in the province in previous years.
The upcoming reviews will continue with the same frequency, and the results will be updated as the mosquito breeding season progresses, which usually intensifies with the heat.
