Blood mosquitoes can 'smell'
Scientists have discovered that sperm from a mosquito smell and that some substances that adult mosquitoes can smell can ensure that the sperm of the mosquitoes will swim faster. It suggests that the sense of smell of the sperm play an important role in the propagation of the mosquito.

Researchers at Vanderbilt University found that in the sperm of mosquitoes very specialized chemical sensors. They are odor receptors that are comparable with the sensors, which play an important role in the olfactory system of an adult mosquito. The olfactory system is located in the antennae (feelers) of the mosquito. The receptors where sperm disposal, are located in the tail of the sperm.

Work and the receptors work, the researchers show. They asked the receptors include exposure to substances that smell receptors can activate. Then the tails of the sperm were moving frequently.

The sperm did not respond to the dust when administered by substances that smell receptors deactivated with simultaneously.

In addition, the researchers showed that it was impossible to activate the sperm. Mosquitoes that were adjusted so that they had no functional odor receptors, "This provides us with compelling evidence that the smell receptors play a role in the reproductive process," says researcher LJ Siebel.
