In an article in the Vancouver Sun there’s a report on the biggest lab breakthrough against mosquitoes in years. Scientists said they had identified odour molecules that baffle the bloodthirsty insects. The molecules disrupt carbon-dioxide sensors that alert mosquitoes to exhaled breath, which signals the presence of a human nearby, the team reported. The work could lead to revolutionary but low-cost repellents to confuse, deter or trap mosquitoes, it said.
They could be invaluable in developing tropical countries, where mosquito-borne malaria is endemic, providing an alternative to DEET, a skin repellent that is expensive, needs repeat applications and is showing worrying signs of resistance.
