Traps collect Aedes aegypti eggs for preventive action

There are 1,004 devices in ten administrative districts of DH to map priority areas in the fight against mosquitoes.

Efforts to combat Aedes aegypti, the mosquito that transmits dengue, zika and chikungunya viruses, are becoming more intense. The environmental control of the federal district has already installed traps that collect the eggs of the insect in ten administrative districts.

There are 1,004 units of equipment spread across Candangolândia, Núcleo Bandeirante, Riacho Fundo, Riacho Fundo II, Recanto das Emas, Planaltina, Samambaia, Guará, Estrutural and in Gama. The Department of Health is already looking into expanding the service.

According to biologist Israel Martins of the Environmental Health Enforcement Administration, egg collections produce maps that identify priority areas for prevention and control actions. “Hereby, we direct the actions carried out by the environmental control agents together with the population,” he explains.

According to the biologist, “the device uses a mixture that attracts female mosquitoes, which lay most of their eggs there.” “The female can lay up to 120 eggs,” he says.

“We distribute the trap in lots with a distance of 300 meters between them, which is the necessary space for the best use of the material. Each week our team collects the material for study and replaces the palette of equipment to continue operations where there is a higher concentration of mosquitoes,” explains Martins.

In addition to ova (mosquito egg trap), the Department of Health promotes area spraying in AZ administrative districts. “This year, 2.5 million properties have already been covered in smoke, in addition to 358,000 deposits that should have been treated,” said Divino Valero, Undersecretary of Health Control.

“We conduct home visits with the aim of educating and correcting dengue problems and eliminating the outbreaks that are detected. Today, 90% of the eggs of the Aedes aegypti mosquito are found in houses,” adds the deputy secretary.
