Conagua reduces Culex mosquito presence at Endhó dam in Hidalgo, maintains fumigation strategy

The National Water Commission (Conagua) reports favorable results in its campaign to control the Culex mosquito at the Endhó dam in Hidalgo, Mexico. Mayela Godínez Alarcón, manager of Water Planning, stated that the first phase of the dam's Master Recovery Plan has successfully reduced both larval and adult mosquito populations.

the first phase of the Plan Maestro de Recuperación de la presa Endho maintains favorable results in the control of this insect.

Monitoring data shows a significant decrease in larval density, falling from 180 to 95 larvae per square meter across five sampling points. Similarly, adult mosquito populations captured in traps in 34 riverside communities dropped from an average of 143 to 76 individuals. These figures indicate that consistent control measures are effective in managing the pest.

Conagua acknowledged that dam recovery is a long-term process, emphasizing the need for a permanent strategy to ensure lasting results. The commission continues its fumigation efforts in 27 priority riverside communities, benefiting over 27,000 residents. These actions involve ground fumigation in more than 9,000 homes, utilizing equipment like ULV, thermal foggers, and sprayers. Some communities have received up to seven fumigation treatments.

these results confirm that the periodic application of control measures contributes to reducing the presence of the plague and support the continuity of a strategy based on permanent monitoring and operational adjustments.

The agency highlighted the use of advanced technology, including drones, to detect areas with higher mosquito concentrations. Despite the dam's 1,264-hectare surface area, fumigation efforts have covered over 2,700 hectares, demonstrating a comprehensive approach to the control strategy.

“

the recovery of the dam will not be achieved with a single intervention, so a permanent strategy is maintained that allows consolidating a lasting recovery, despite the favorable results obtained to date.
