Genetically grown Dengue mosquito kills its own species.

Genetically grown Dengue mosquito will kill its own species

Gone are the days of those science fiction movies where it was fantasized as a story line that in a lab, genetically malfunction human converted into a monster and start killing human species.

 So to call it a good luck for dengue affected countries, but a marvalous breakthrough in the field of biotechnology. A british biotech lab has devised a way and created a species of dengue mosquitoes that kills its own larva. just imagine a mosquito giving eggs and the other one killing those larvae - and yet both belong to the same breed.

A lab grown species of dengue mosquito has been already released in Florida whose one and only deadliest trait is to kill their own offspring. Yup that means that a kid won;t be able to reach the adulthood because of the genetically introduced disease their parents gave them.

About Dengue: Dengue mosquito is re known for deadly Dengue fever also known as breakbone fever, is an infectious tropical disease caused by the dengue virus. Symptoms include fever, headache, muscle and joint pains, and a characteristic skin rash that is similar to measles. In a small proportion of cases the disease develops into the life-threatening dengue hemorrhagic fever, resulting in bleeding, low levels of blood platelets and blood plasma leakage, or into dengue shock syndrome, where dangerously low blood pressure occurs

Though this technique of genetically modifying insects already exsist decades age, but this is the first time it has been used successfully for mosquitoes. we hope that this technique won't kill the whole insect species of mosquitoes and also it is not sure what impact it will make on the environment.
