A second Malaria causing mosquito has been discovered in South Africa .
Malaria in South Africa is close to being eliminated but to complicate matters scientists have identified a second mosquito transmitting the disease.
There are lots of tall tales about mosquitoes and how malaria is transmitted. Here are sturdy facts on the disease.

It's hard to contain a mosquito-borne infection like Zika when the conditions are ideal for it to spread.
Mosquitoes are repelled by chicken odours and will actively fly outside when they encounter them.
Anopheles arabiensis is the world's most common, malaria-carrying mosquito. Now it's emerged that chickens emit an odour that can repel the deadly insects.
The outbreak of Zika virus in Brazil had Australian travellers on alert but transmission is only possible in tropical Queensland.
New research shows common local mosquitoes aren’t able to spread Zika. This means Australia is unlikely to see a major outbreak of the disease. But a risk remains in northern Queensland.

A computer model suggests that while more cases of Zika can be expected in the continental U.S. outbreaks will probably be small and are not projected to spread.
The Koka Reservoir in Ethiopia. Steps have been taken to reduce malaria infections without sacrificing the primary purposes of the dam.
The construction of dams in Africa, in some cases, bring an unintended consequence – an increase in malaria in the surrounding areas.
Is a Zika vaccine being tested ahead of vaccines for other flaviviruses because Zika’s occurring in the context of an international sporting competition?
Recently two events concerning the Zika epidemic coincided: two potential vaccines against the virus were declared a success when used in mice, and Jason Day withdrew from the Olympic Games.
Aedes aegypti mosquitoes are at the center of Zika virus’ spread.
Look beyond transgenic techniques that add new genes to a species. People have used selective breeding techniques to change plants and animals for millennia – why not try them on mosquitoes?

Aedes aegypti mosquitoes is seen next to larvae in a laboratory conducting research on preventing the spread of the Zika virus and other mosquito-borne diseases, at the Ministry of Public Health in Guatemala City.
Aedes aegypti is adapted to live in close proximity with humans, and this close association likely contributes to the severity of the Zika outbreak.

Satellite imaging can locate mosquito-friendly environments, allowing us to predict the advance of diseases they carry.
Even if Zika sometimes causes pregnant mothers to have babies with microcephaly, this does not necessarily mean every infected mother would have an affected baby.
Despite all the hype around Zika, crucial questions remain unanswered. How great is the risk that infection during pregnancy would result in a baby with microcephaly? And what can be done to prevent this?
Municipal workers wait before spraying insecticide to prevent the spread of Aedes aegypti mosquito at Sambodrome in Rio de Janeiro, Brazil, January 26, 2016.
Zika was discovered almost 70 years ago, but wasn't associated with outbreaks until 2007. So how did this formerly obscure virus wind up causing so much trouble in Brazil?
There is little doubt the virus can make it to Australia.
They’re small, spindly insects but their threat never dwindles – the bites of mosquitoes threaten death and disease in many parts of the world.
Why do mosquitoes not suffer from the infections they pass on?
There's something about mosquitoes that means they don't get sick from the infections they carry. So can we turn that function off, genetically?
Many more where these came from.
A good summer picnic, bushwalk or barbecue with friends and family can all be ruined by those annoying flies that never leave you alone. So what are they after?
New genetic technology could change the DNA of entire species to prevent them from spreading diseases.
The yellow fever mosquito Aedes aegypti isn’t put off by this ‘mosquito repellent’ wrist band.
While slipping on a wrist band or sticking on a patch may be an attractive alternative, they’re unlikely to provide any substantial protection from biting mosquitoes.
Disase carrying insects are attracted to light bulbs – a constraint of domestic solar energy.
Solar is a vital piece of the energy puzzle for Africa, but there is an insect problem that comes with the light from solar.
