The World Health Organization warns of stopping global progress against malaria

According to Emma Batha

LONDON – (Thomson Reuters Foundation) – United States scientists said Tuesday they had an important step towards the development of drug control of "mosquito birth control", causing hundreds of thousands of deaths to spread malaria and other killers.

Researchers at the University of Arizona discovered a special protein of female mosquitoes, and their young was criticized for their baby.

When scientists blocked the protein, women put eggs in shells and killed embryos.

The group says they develop drugs that target proteins, it could be a way to reduce mosquito populations, such as harming non-bees' insects.

"The discovery is important," Roger Miesfeld, at the University Chemistry and Biochemistry Department, said the Thomson Reuters Foundation on the phone.

"We are definitely excited about … Mosquito resistance is achieved and another biochemical option is much better (than other methods)."

Mosquitoes are one of the deadliest animal in the world, according to the World Health Organization (WHO), warns of stopping global malaria progress.

In 2016, about 216 million people were infected with diseases, 445,000 babies were killed, especially babies and young children in sub-Saharan Africa.

Other diseases spread by food are Zika, Chikungunya, fever yellow, West Nile virus and dengue. Over the last decades it has risen 30 times, according to the WHO.

Miesfeld has said that modern mosquito control methods have long been used to make insects become resistant.

The research team was surprised that the treated women could not reproduce for the rest of their life for two or three weeks.

"When we quit that protein (mosquito) it's no longer feasible for egg after several blood feedings … so birth control is an excellent way to describe it."

This discovery has been running for five years to develop a new generation of insecticides.

They could use nets and other places in the same rabbit in the same way and mosquitoes would absorb it through the legs and the body.

Miesfeld said the discovery – published Tuesday in the scientific journal PLoS Biology – would help reduce mosquito populations in epidemic diseases, but scientists would not want to eliminate insect, a pollinator.

"The mosquitoes are part of the ecosystems. I'm not going to get rid of mosquitoes," he said.
