For years, researches who attempted to create genetically at immune mosquitoes that cannot infect humans with malaria which claims over 1 million lives worldwide every year.
Now for the first time scientists claim to have successfully succeeded in generating altering mosquitoes in a way which renders them completely immune to the parasite, a single cell organism called plasmodium. For the research the researchers used molecular biology techniques to design a piece of genetic information capable of inserting itself into a mosquito’s genome. This construct was then injected into eggs of the mosquitoes. the emerging generation carries the alter genetic information and passes it to the future generations .the scientists studied all the genetically modified mosquitoes alter feeding them a malaria infested blood they notice the plasmodium did not infect a single study animal.
They were surprised how well this worked ,the scientists hope that someday they will be able to replace wild mosquitoes with ab-bred populations viable to act as vectors that is ,replace the malaria causing parasite. The wild mosquito lives for average of 2 weeks and by reducing their life span the infections can be reduced.
The entire research is an astounding step for the eradication of the malaria parasite.

there are two particular issues dat need to b addresd:
firstly can dese species of mosquitoes breed in the presence of their more competetive and already prevalent brothers and secondly even if it manages to replace the "pioneer" community of mossies, wat are its effects or more specifically side effects gonna be to the environment????
do u have any more infrmation about this topic,just elaborate it.....
