Billboard mimics human sweat to entrap Zika-carrying mosquitoes

A few advert businesses in Brazil put in two particular billboards in Rio de Janeiro, which do not endorse any sort of good or service. As an alternative, these billboards have been designed to lure and kill Zika-carrying mosquitoes. They appeal to any Aedes aegypti as much as 2.5 miles away by emitting an answer containing lactic acid and carbon dioxide that mimic human sweat and breath, respectively. As soon as the mosquitoes flock to the billboards, they get sucked contained in the glass panel, the place they’re trapped till they die.

The businesses, Posterscope and NBS, launched the set up’s technical blueprint on-line and are encouraging different corporations and cities to construct their very own. It prices round $192 to make one in every of these billboards. Dr. Chris Jackson, a pest management professional from the College of Southampton, advised the BBC that something that may scale back the prevalence of Zika-carrying mosquitoes is an effective factor. The Zika virus continues to threaten the well being of pregnant ladies and their infants in Brazil, in any case — the CDC even confirmed that it causes extreme start defects, together with microcephaly. He warns, nevertheless, that these kinds of installations is perhaps extra appropriate for low-density places. “[O]therwise,” he stated, “you are pulling in hungry mosquitoes and offering them with uncovered human flesh.”
