Mosquitoes are able to remember the smells associated with danger, and subsequently to avoid them. It can help in the development of means to combat the mosquitoes that carry dangerous diseases. This is the conclusion of biologists from the University of Washington in the United States, their work publishes Current Biology.

In the study, females aegypti mosquito was placed in a chamber where was the cloth with the smell of different humans and mice. When the test subjects she sat down, scientists with vibration simulate protection of the victim from the bite.

After 24 hours, mosquitoes were released in a different space with two corridors — one scientists launched the air odorless, but different from the scents of the previous experiment. While insects are not flying on that corridor, where was the smell of their previous «victims», «gave back.»

The study notes that remember the smells mosquitoes helps dopamine — genetically modified individuals who had hampered the development of this hormone, did not distinguish the flavors.

The authors believe that their discovery could be of great benefit to medicine. So, the violation of the production of dopamine through genetic engineering can wean mosquitoes find the smell of people and afraid of sudden movements.
