Read Now My dear countrymen, Namaskar. Today, the entire country is celebrating Rakshabandhan.
Messenger Mosquitoes are some of the most deadly creatures on the planet. They carry viruses, bacteria and parasites, which they transmit through bites, infecting some million people and killing more than 1 million each year.
With international travel, migration and climate change, these infections are no longer confined to tropical and subtropical developing countries. Pathogens such as West Nile virus and Zika virus have caused significant outbreaks in the United States and its territories that are likely to continue, with new invasive pathogens being discovered all the time.
Ways of curbing dengue, control of these diseases is mostly limited to broad-spectrum insecticide sprays, which can harm both humans and non-target animals and insects.
What if there was a way to control these devastating diseases without the environmental problems of widespread insecticide use?
A study released in May suggests Zika began spreading in Florida mosquitoes about three months before infections showed up in the Miami area in the summer ofand the virus likely was carried in by travelers from the Caribbean.
Today, genetically modified GM mosquitoes, developed during the past several decades of research in university laboratoriesare being used to combat mosquito-borne pathogens — including viruses such as dengue and Zika — in many locations around the globe, including the United States.
Progress is also being made to use GM mosquitoes to combat malaria, the most devastating mosquito-borne disease, although field releases for malaria control have not yet taken place. I have been working on GM mosquitoes, both as a lab tool and to combat disease, for over 20 years.
During that time, I have personally witnessed the technology go from theoretical, to seeing it used in the field. Ways to use genetically modified mosquitoes A worker sprays anti-mosquito fog in an attempt to control dengue fever at a neighborhood in Jakarta, Indonesia.
Highly populated areas in the country are often hit with severe outbreaks of the mosquito-borne disease especially during the annual rainy season due to poor health services and unsanitary living conditions. While the concept of gene drive in mosquitoes is many decades oldthe gene-editing technique CRISPR has finally made it possible to easily engineer it in the laboratory.
However, CRISPR-based gene drives have not yet been deployed in nature, mostly because they are still a new technology that lacks a firm international regulatory framework, but also due to problems related to the evolution of resistance in mosquito populations that will stop the gene from spreading.
By this definition, the first gene drive that has been deployed in mosquito populations for disease control is a bacterial symbiont known as Wolbachia. Wolbachia is a bacterium that infects up to 70 percent of all known insect species, where it hijacks the insect reproduction to spread itself through the population.
Thus, the Wolbachia itself with its genome of approximately 1, genes acts as the genetic trait that is driven into the population. When Wolbachia is transferred into a previously uninfected mosquito, it often makes the mosquito more resistant to infection with pathogen that can cause disease in humans, such as multiple viruses including dengue and Zika viruses and malaria parasites.
Thousands of bacteria-infected mosquitoes are flying near Miami to test a new way to suppress insect populations that carry Zika and other viruses.

Those modified insects were then released in a dozen countries to control the disease.Due to dengue outbreak recently, we are really concerned about the residents’ health especially the children.
Fogging service also was not done accordingly to the schedule.
The fogging authority only did their job whenever a case of dengue aroused. Unnecessary delay in dengue prevention and etc. Health resources have not succeeded in curbing dengue cases.
