Hi rojfitness: Mosquitoes are "just" carriers or in another word "victims" of the dread diseases --too--.
Why don't we eradicate cigarettes, alcoholic drinks, cars and yes "pure sugar"? ;-)
There are a lot of learning and stories with pictures out there (on the Net), one can spend a lifetime on. ;-)
Ecologically, mosquitoes are also "food" for fish, birds and reptiles. Because mosquitoes get nectar (energy food) from plants, they are said to be "pollinators" too. We have much more to learn!
Dear หมอเจ๊ คนสวย แซ่เฮ : Long time - no see! How are you?
I should write another blog in g2k about mosquito research but let me share current "thinking" on mossy:
http://insects.about.com/od/flies/a/10-facts-about... says : Mosquitoes may carry any number of deadly diseases, including malaria, dengue fever, yellow fever, and encephalitis. Mosquitoes also carry heartworm, which can be lethal to your dog. Female mosquitoes need protein for their eggs, and must take a blood meal in order to reproduce.Some mosquitoes specialize on other animals, and are no bother to us at all. Culiseta melanura, for example, bites birds almost exclusively, and rarely bites humans. When the male and female meet, their buzzing synchronizes to the same speed.Most mosquitoes emerge from their watery breeding ground and stay pretty close to home. But some, like the salt marsh mosquitoes, will fly lengthy distances to find a suitable place to live, with all the nectar and blood they could want to drink. An adult mosquito may live 5-6 months.Mosquitoes can detect carbon dioxide from 75 feet away.Carbon dioxide, which humans and other animals produce, is the key signal to mosquitoes that a potential blood meal is near. They've developed a keen sensitivity to CO2 in the air. Once a female senses CO2 in the vicinity, she flies back and forth through the CO2 plume until she locates her victim. http://nittygrittyscience.com/2011/05/04/human-blo... suggests in :
So what’s the secret ingredient in human blood?No one knows for sure, but there have been some guesses made. One clue is that human blood is rich in an amino acid called threonine. Threonine is a key amino acid needed for the production of mosquito egg proteins. Threonine is also an nutrient that Wolbachia can’t make by itself–it has to get it from its host. Wolbachia may be depriving the mosquito’s eggs of threonine, leading to the loss in fertility when fed on non-human blood, which is lower in the amino acid.Another possibility is cholesterol. Human blood tends to have more of it than that of say mice or chickens. Wolbachia needs cholesterol to make part of its cell wall, and the mosquito needs it to replenish its fat stores, creating another potential conflict between Wolbachia and the host mosquito.www.isaaa.org/kc/cropbiotechupdate/article/default... reports GM Mosquitoes Deployed to Control Asia's Dengue FeverAn initial field trial carried out in the Cayman Island last year, where about 300 million GM male mosquitoes were released, resulted to a decrease by 80% of the mosquito vector Aedes aegypti. In Malaysia, under the supervision of the Malaysian Institute of Medical Research, 6,000 male GM mosquitoes have been released in 21 December and was successfully completed in 5 January. The scientists hope to conduct bigger trials to test the technology further on its impact in the spread of the dengue virus.
