Zika Virus, Mosquito Vs. Human , War of Pesticide ? No more

by Sujan Adhikari | 01-02-2016 01:00



For such a tiny creature, mosquitoes have caused humans untold misery for millennia. The insect, which measures no more than a few millimeters in length, has killed tens of millions of human beings by spreading deadly diseases like malaria and dengue fever with its bite.

 

The Zika Virus, which scientists believe may be causing severe birth defects in newborn children whose mothers had been infected, is the latest mosquito-borne illness to strike fear in the public as it explodes through Latin America and threatens the U.S.

 

Aedes aegypti mosquitos are seen in a lab test in American Countries like Brazil, Argentina. The mosquito transmits the Zika virus and is being studied at the institute.

Zika has once again raised the question of how to stop mosquitoes from transmitting disease.

 

 

But if mosquitoes have been killing human beings, human beings have long been doing the same—with varying levels of success. But none of these methods worked sustainably. So, Insects are developing tolerance and resistance against pesticides we use widely.

 

But still we have hope, hope for new method we can apply to control Mosquito, its not other than Recombinant DNA technology or gene modification.

 

 

New Gene Editing method had been practiced in lab and is successful too and now New Era begun in control of Mosquito.

 

Humans have tried to protect themselves against the scourge of mosquitoes for centuries. Ancient Egyptians are said to have slept under the nets to avoid the insects, which feed at night. Native Americans applied muds and plants to their skin to keep the bugs away. But none of the methods stopped or even slowed mosquitoes attack.

 

In world including Nepal, People started using DDT (now banned) to control Malaria. And later it became popular in Nepali?s field to control insect, pests but it didn?t last longer as it carried severe problems to health and crops too.

 

After gene modification methods , mosquito will continue but soon its population will fall down as it will cause them problem in reproduction.
