Mosquitoes ‘put off biting’ by human diet medications

Researchers say they may have found a way to reduce the appetite of blood-hungry mosquitoes, by giving them human diet medications

This left them feeling full and bloated and put them off biting, US researchers said.

They said the technique could be used to prevent illnesses such as Zika, yellow fever and malaria.

Be that as it may, their research is still in its beginning stages, the examination in the journal Cell reports.

The specialists, from Rockefeller University in New York City, directed their experiments on Aedes aegypti mosquitoes.

Female mosquitoes of this species – who are the main ones who bite – are wildly attracted to human beings, on the grounds that their blood contains the protein they have to produce their eggs.

When bolstered, that fascination in people leaves, leaving them with little interest in another blood meal for several days.

No hunger

At the point when the analysts gave the mosquitoes a saline arrangement containing the diet medications, they were foramazed to find that the mosquitoes’ appetite plummeted, just as it does in humans.

To quantify this, they dangled a touch of nylon stocking full of body odour belonging to study author Laura Duvall, a postdoctoral individual at Rockefeller University, before them.

They then tested all of the mosquitoes’ neuropeptide receptors with the drugs and found which specific one was in charge of controlling and switching off a mosquito’s appetite.

This learning would now be able to enable them to discover where it is produced in the insect’s body and how it is activated to control feeding behaviour.

The scientists likewise distinguished an alternate compound, instead of a human diet medicate – which would not be appropriate for use in the wild – which could turn the creepy crawly’s hunger on and off.

‘Run out of ideas’

The research team says its discoveries have huge implications for future research.

“We’re starting to run out of ideas for ways to deal with insects that spread diseases, and this is a completely new way to think about insect control,” says senior author Leslie Vosshall, head of the laboratory of neurogenetics and behaviour at Rockefeller University.

“Insecticides are failing because of resistance, we haven’t come up with a way to make better repellents, and we don’t yet have vaccines that work well enough against most mosquito-borne diseases to be useful.”

Ms Duvall said focusing on mosquitoes’ appetites was a good idea because it used what came naturally to them, but it was not an attempt to eradicate the insects because the effects of drugs were not permanent.

She envisaged the drugs being delivered to female mosquitoes in the wild using traps attractive to the insects.

“We are multiple steps away from using this in the field, and we will always need other complementary strategies alongside this,” she said.
