Mosquitoes 'disappearing' in some parts of Africa (scientists are unsure as to why)

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..

Lack of food,Most likely as dry denuded earth cannot support much life.

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.

Malaria exists only because it has fresh victims.
Africans are more likely to be immune to Caralie mosquito bites...

Drat.

Now the collectivists are going to have to use some other means of killing millions of Africans.
