Ever thought why mosquitoes are attarcted to human. Very simple. To feed on blood. But, human blood makes mosquitoes wild. This is really interesting secret. But it is no longer a mystery. Scientists have found why it is so. Yes, American scientists have identified that it is because of a kind of pheromone - nonanal. The only other organism to secret this substance are birds. But at least I have never seen mosquiotes feeding on birds, may be mosquiotoes can not reach birds.
Nevertheless, this discovery, will certainly lead in the long run effective programs in controlling deadly epidemic diseases like Malaria. The next logical step now is to understand the sensory mechanism in mosquitoes that is responsible for recognising the nonanal, with the help of technologies like Scanning Electron Microscopy.
In the contrary, medicines can be discovered targeting to reduce the level of nonanl secretion be human or diulte its concentration.
Anyway, you can read the findings in the following link
