Mosquitoes 'disappearing' in some parts of Africa (scientists are unsure as to why)
BBC.co.uk ^ | 8/27/11 | BBC News

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.

Probably using DDT but concealing that fat so as to to set off a global embargo.

Most animal populations have natural booms and busts. See what the skeeter population is in five years or so.

Good luck. lol

All them lakes and ponds.. and puddles ... I don’t miss the skeeters, I miss the ice fishing tho and if the crappies and walleyes are biting , ya can endure a little nip or two.. wifey swells up if a skeeter bites her and she hates the cold tho, she’s an island girl.. but even Hawaii has skeeters ..

I visited drier climes in AFRika and Middle East in the 80s, never swatted one the whole time.. but I never was in the rain forest and damper areas either, unfortunately. That’s where the real wild life hang out..

minnesota needs mosquitoes. Fish eat mosquito larva so if there was a drop in mosquitoes, fish would starve, and minnesota would lose tourism from vacationing fishermen.

That was my first thought too - my second was 'what if some liberal decides to 'save the mosquitoes'? They're nutty enough to do it.

Is this supposed to be bad news? We just returned from Yellowstone and the Tetons. I sure wish the damn bugs would disappear from there. And we were told they were mild in July compared to May - June when the horses were just covered with them this year.

scientists are unsure as to why. ?

My guess would be that the globally banned DDT is being blackmarketed and used there..........lets hope so.

You are correct.

As an aside, any good chemist can make DDT at home. All the ingedience to make DDT are found at google. The only thing is that I did not find the measurments for the recipe. But then, a good chemesist would know it already.

Thats the first thing that I thought of. DDT does wonders against mosquito's, lasts a long time, and one needn't use a whole lot of it.

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.

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.

More likely this is a sign of hope for Minnesota's mosquitos.

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.
