Malaria-carrying mosquitoes are disappearing in some parts of Africa, but scientists are unsure as to why.
Figures indicate controls such as anti-mosquito bed nets are having a significant impact on the incidence of malaria in some sub-Saharan countries.
But in Malaria Journal, researchers say mosquitoes are also disappearing from areas with few controls.
They are uncertain if mosquitoes are being eradicated or whether they will return with renewed vigour.
Data from countries such as Tanzania, Eritrea, Rwanda, Kenya and Zambia all indicate that the incidence of malaria is dropping fast.
Researchers believe this is due to effective implementation of control programmes, especially the deployment of bed nets treated with insecticide.
But a team of Danish and Tanzanian scientists say this is not the whole story. For more than 10 years they have been collecting and counting the number of mosquitoes caught in thousands of traps in Tanzania.
In 2004 they caught over 5,000 insects. In 2009 that had dropped to just 14.
More importantly, these collections took place in villages that weren't using bed nets.

If it’s because Africa is becoming more arid, that is not a good thing.
Global Warming?
.
The idea that it could be due to the increased use of bed nets is pretty stupid when you think about it.
Mosquitoes aren’t only a pest of humans, but any warm blooded animal or bird. Last I heard there’s lots of animals and birds in Africa, and none of them sleep with bed nets over them.
Naw, I’m sure your state bird is okay.

Not just MN, when we were stationed in NW North Dakota the mosquito was considered to be the state bird. In the Grand Forks area there have been regular problems with Eastern Equine Encephalitis. Maybe the malarial parasite is more quickly killing off the carrier.
Maybe we can bring back the mosquito by injecting their eggs with tyranosaurus DNA.
Cooler dryer climates are a sign of the impending return of the Big Ice ~ which has happened numerous times over the last few million years.
Minnesota mosquitos are well adapted to such a climate and will undoubtedly spread to Africa to take the place vacated by their moist warm Earth cousins.
Bought one of thos a few yrs back. It didn’t work at all.
I’ve watched Lilo and Stitch. It’s the only thing saving Earth from destruction.
Black flies. Nothing depends on Black Flies.
If black flies were eradicated life would be very good
It’s part of the oceans ceasing to rise and the planet beginning to heal.

Not only fish and tourism impact, but birds, frogs, mosquito repellent vendors, and t-shirt vendors. I think with no mosquitos, Minnesota turns into a vacant lot.
Looks like most of us agree... they went rogue with DDT. Now we need to do they same thing but with bed bugs.
It’s global warming.
