🦟🛑 We've known for a long time that female #mosquitoes stop hunting once they've had their fill of blood, but where does that "off switch" live? New #research explains that it isn't in the #brain – it's in special cells in the mosquito's rectum.

Mosquitoes get the ‘I’m full’ signal from their butts, not their brains

Mosquitoes stop feeding because signals from rectal cells tell them they’re full, offering a target for preventing human bites.

#News: #Deforestation is making mosquitoes bite humans more! 🧐🦟 As #forests disappear, #mosquitoes lose their natural prey and target us instead, spreading diseases like #Zika and #dengue fever. 🌴☠️🚫 #BoycottPalmOil #Boycott4Wildlife @palmoildetect.bsky.social https://www.sciencedaily.com/releases/2026/01/260115022754.htm?utm_source=mastodon&utm_medium=Palm+Oil+Detectives&utm_campaign=publer
Female #mosquitoes utilize a specific receptor, Neuropeptide Y-like Receptor 7 (NPYLR7), located in their rectal tissues to signal satiety and suppress the urge to seek further blood meals after feeding.

Using mosquitoes to vaccinate bats could curb the spread of deadly diseases

But scientists say there are practical and ethical challenges to overcome before the strategy could be deployed in real-world settings.

Forest loss is driving mosquitoes’ thirst for human blood

In the rapidly disappearing Atlantic Forest, mosquitoes are adapting to a human-dominated landscape. Scientists found that many species now prefer feeding on people rather than the forest’s diverse wildlife. This behavior dramatically raises the risk of spreading dangerous viruses such as dengue and Zika. The findings reveal how deforestation can quietly reshape disease dynamics.

🦟🩸 It turns out our long, itchy history with #mosquitoes goes back nearly two million years.

Recent genetic #research suggests that as early human ancestors migrated, certain mosquito species evolved a specific "taste" for us to survive dry seasons.

In Singapore:

"Faculty at the Environmental Health Institute in Singapore’s National Environment Agency, along with a few collaborators, selected 15 densely-populated areas of the city-state and randomly divided them into groups that would receive a transplanted swarm of IIT-SIT male mosquitoes, and others that would receive none."
