GENETICALLY modified mosquitoes that were
designed by scientists to help populations decrease are actually thriving.
This is according to new research that claims
the plan to create gene-hacked mosquitoes that have offspring which die
immediately has spectacularly backfired and now scientists don't know what will
happen next.
The modified mosquitoes were released in
Jacobina in Brazil and were supposed to mix with the local population and
decrease numbers with their weak offspring genetics.
Although the wild population did plummet for a
short while, 18 months later it was right back up again.
This is mostly concerning because scientists
think the new 'super mosquitoes' have properties that might make them harder to
kill.
Research about the pests has been published in
the journal Nature Scientific Reports.

Mosquitoes like the Aedes aegypti variety that
was edited can carry dangerous diseases like yellow fever, Zika virus and
Malaria.
This is why efforts are being made to reduce
their numbers.
However, now traces of the genetically
modified genes have been found in the natural population.
This means they are successfully
interbreeding.
The researchers concluded: "It is unclear
how this may affect disease transmission or affect other efforts to control
these dangerous vectors."
The offspring of the gene-hacked mosquitoes
and the natural ones are thought to be more robust but whether they pose a
threat is unknown.
Researcher Jeffrey Powell told News
Atlas: "It is the unanticipated outcome that is concerning."
Oxitec, the British biotech company running
the project, assured members of the public that this negative result would not
happen.
It then released 450,000 genetically mutated
mosquitoes into the wild where interbreeding caused the spread of the mutated
genes because the offspring failed to die.
Oxitec disagrees with some of the information
published in the research paper about its experiment and is said to be working
with Nature Research publishers to make changes.
Mosquito Facts
Here's what you need to know about the tiny
pests...
- Only female mosqutoes bite
humans, they need the blood to help their eggs develop
- There are more than 3,500
species of mosquitoes in the world
- Mosquito is Spanish for
"little fly"
- The insect can drink up to
three times its weight in blood
- The average mosquito lifespan
is less than 2 months long
- They spend their first 10 days
alive in water
- The tiny creatures can smell
human breath
- They are picky about the smell
of your sweat
- They have been around since the
Jurassic period
- They do not actually spread HIV
because the virus is digested in their stomachs
