Zika
virus has elevated many tensions and worries among the world’s population since
last several months. Scientists from all around the world are making attempts
to cut down the spread of this virus. To reduce the spread of this virus,
genetically engineered mosquitoes have been produced. Male mosquitoes
containing the gene are released to mate with wild females. These male mosquitoes
contain a gene that will kill their offspring before they reach adulthood. In other
words, they will reduce the mosquito population. These insects have shown
effectiveness in Brazil and other countries in reducing the mosquito population
that transmit both Zika and dengue fever. The Federal Government has approved
the release of genetically engineered mosquitoes into the wild for the first
time in the United States. It has been allowed to see if the field test might
help slow the spread of the Zika virus. A British company, Oxitec has developed
the genetically engineered mosquitoes and the test would be done in Florida. The
genetically modified mosquitoes would be released up to three times a week for
as long as 22 months, to determine whether the population of wild mosquitoes is
reduced. The F.D.A and the company have said that the mosquitoes were unlikely
to establish themselves in the wild because they are programmed to die. Also,
these insects would not cause any problem to people because the male mosquitoes
being released do not bite.
I
think this field study has a lot of potentials to reduce the mosquito
population that spreads the Zika virus. Since the F.D.A. has approved that the
genetically engineered insects would not cause any problem for people, then
there are some hope that the Zika virus can be prevented from spreading. Also, the
applications of these insects have shown positive results in Brazil and some
other countries. So, we can hope that Zika virus will be reduced by utilizing the genetically engineered mosquitoes.
