Warm weather has arrived and that means our annual battle against mosquitoes is back on. Here are five ways to mosquito-proof your backyard that don’t rely on spraying insecticides.
Murray Valley encephalitis has been detected in south-eastern Australia. No human cases have yet been reported, but past outbreaks after floods show we need to be cautious.
Mozzies can make you sick by injecting a cocktail of saliva and virus when they bite. Ross River virus has long been a risk but now we’re also contending with the more serious Japanese encephalitis.
Tracking mosquitoes in our backyards, such as Aedes notoscriptus, helps authorities work out future health risks.

The mosquito-borne Japanese encephalitis virus has been detected for the first time in southeastern Australia, in pigs at a pig farm. So what threat does it pose to human health?
In 2018 scientists of the Miami-Dade County Mosquito Control tested a new way to suppress mosquito populations carrying the Zika virus.

Release of GM mosquitoes in Florida is imminent. But a multidisciplinary team of scientists believe that more studies are needed first. They encourage a publicly accessible registry for GM organisms.
Feel like mosquitoes are picking you out of a crowd when looking for someone to bite? It may come down to the smell of your skin and how heavily you breathe.
Leaving water out for wildlife is important during droughts and bushfires but if it’s not changed regularly it can be a breeding ground for mosquitoes.

Temperatures are soaring and bushfires are decimating Australia’s wildlife. So how can we avoid creating a breeding ground for mosquitoes when putting water out for thirsty birds and animals?
Although yellow fever does not currently exist in Australia, the species Aedes aegypti - which can transmit the disease - is found widely across northern Queensland. The virus remains a global health concern, but citizen scientists could help prevent its spread.

Nuisance-biting and mosquito-borne disease are ongoing concerns for health authorities. But an effective citizen science program is now showing how all of us can help beat the bite of mozzies.
Africa is home to 92% of malaria cases and 93% of malaria deaths.

The aim is to discover, develop and facilitate delivery of anti-malarial medicines to help tackle the burden of malaria in endemic countries and support malaria eradication.
Mosquitoes love sugar – so much so that can delay their search for our blood. Now, their sweet tooth may have revealed an important genetic weapon against the spread of mosquito-borne disease.
Australia’s dengue cases are usually limited to far north Queensland.

Mosquito-borne dengue virus returned to central Queensland after being absent for decades. But while most Australian cases involve travellers, this one is locally acquired.
The Culex annulirostris mosquito and waterbirds are responsible for spreading Murray Valley encephalitis.

Thousands of Australians contract Ross River virus each year. Mozzies can infect us with their bites, but only after they’ve bitten an infected animal host.
Could the sounds from our smartphones repel or attract mosquitoes?

The sounds of mosquitoes may be annoying to many but tuning into their musical whines could help design new mosquito traps. Just don’t expect sounds from your smartphone to protect you from bites!
In the future, traps for mosquito that spread the dengue and chikungunya virus could be made from the carbon dioxide in human breathe as well as body odour.
Set to land in mid 2018, the new mosquito emoji will give people a new way to talk about mozzies.

The mozzies are coming! A mosquito emoji will be available on your devices in mid 2018, providing a new angle for communicating the science and health implications of these very dangerous insects.
Some experts have likened burning a mosquito coil in a closed room to smoking 100 cigarettes.

Australian mosquitoes, unlike their Asian and American counterparts, can still be controlled by insecticides like pyrethroids. What lessons are there for managing pesticide resistance in insects?
Tiny bug, major disease spreader.

Several sites in the US are releasing bacteria-infected mosquitoes as a way to fight mosquito-borne viruses that threaten people. What’s the science – and how well will it work?
