With some delay, I’m happy to share our new preprint: www.biorxiv.org/content/10.6... ! In this work, we aimed to better understand the role of the microbiota in mosquito larval development and nutrition.

The microbiota affects energy production, nitrogen excretion and sterol metabolism in mosquito larvae

Mosquito larvae rely on a living microbiota for normal development because the microbiota supplies essential nutrients, particularly vitamins. Beyond vitamin provision, transcriptomic data suggest tha...

Enteric viral infections promote systemic accelerated aging in Drosophila

Do viral infections accelerate aging, and does this acceleration scale with pathogenicity? Using transcriptomic aging clocks, we measured biological age in Drosophila infected with four enteric RNA vi...

In my first Drosophila study at @salehlabparis.bsky.social, we found that: 1. Enteric viral infections accelerate aging. 2. Even if the infection is cleared, aging process remains triggered. 3. Accelerated aging correlates with reduced lifespan. 📑Preprint: www.biorxiv.org/content/10.1...

Hello mosquito 🦟 and microbiota 🧫 🦠 aficionados, we are looking for a postdoc to join our team (Saleh's lab @salehlabparis.bsky.social at Institut Pasteur @pasteur.fr ) to investigate the interplay between the mosquito, its microbiota, and arboviruses. More information here 👇

I'm so excited to share this with all of you! This is the very first paper where I am the first author 🥹 Let me share some insights about our work 👇🧵(1/5): How do persistent viral infections impact the host? What happens when a fly becomes persistently infected by a virus?

🚨 Ph.D. Opportunity! 🚨 I’m recruiting students to start in the Spring Semester 2026 (Jan 2026) or the Fall Semester 2026 (Aug 2026) to study the behavior & neurobiology of mosquito-host interactions. Know someone who’d be a perfect fit? Please share! 🦟 #Mosquito #Neurobiology #VectorBiology #Itch

URGENT: FlyBase has lost practically all its funding overnight; even user fees are tied up in denied grant funding. 🤬🤯 Any lab using @flybase.bsky.social please donate using the link in post below. This incredible community, on whose backs our #Drosophila labs depend, can't be left out to dry.

Marc Dionne@marcsdionne.bsky.social · last yr.

My lab studies bacterial infections. We spend a lot of time looking at (or for) species-specific genetic and genomic databases for hosts and microbes. FlyBase is the best of all—there is literally no comparison. Its existence is under threat. Please donate. www.philanthropy.cam.ac.uk/give-to-camb...

Mosquito people I have a problem: I am trying to blood feed mosquitoes using parafilm as a membrane, but the mosquitoes are not able to feed. They probe a lot (=they can sense the blood) but can’t really feed.. I’ve done this before and it wasn’t a problem (although mosquitoes were from another

Hi everyone, what's up? We have our monthly seminar this week, with some super cool work on arbovirus entry receptors from leading researcher Jolanda Smit from @unigroningen.bsky.social All welcome - help spread the news with a re-post 🙂 NOTE THE EARLIER TIME for everyone outside the USA

This #InternationalWomensDay I want to tell the story of Lilian Vaughan Morgan. I learned of Lilian this past year - what a badass. Lilian was a leading scientist when women weren't welcome in the lab, nor even the department. But she contributed immensely to the genetics of sex determination 1/n

Check out our paper, co-authored by @akhorramnejad.bsky.social and me. Published in @commsbio.bsky.social We explore how global change will affect mosquito-virus interaction. We use single or multi-generational exposure to heat to address this. A 🧵 with our results (1/5) rdcu.be/d8wse

Great work from Emmanuelle Clervil from Institut Pasteur de la Guyane, who just defended her PhD on the feasibility and acceptability of Wolbachia in French Guiana: important data to start discussions of this application in European territories.

Super happy to be back to French Guiana for the kick-off meeting of Amazed, a collaborative project that will explore the factors driving the emergence of arboviruses!
