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...

Kicking off 2026 the best way we know how: together! 🥐👑 Our annual Galette des Rois brought the team together, and Mori Yoshida claimed the crown for the 4th year running! 🎉 But the real treasure? These moments that unite us before another year of discovery. Here's to an incredible 2026! 🔬✨
Not all bacteria are beneficial in every context. We found that enriching Drosophila with a commensal bacterium reduces tolerance to viral infection. The effect was virus-specific and occurred without changes in viral load, immune gene expression or intestinal damage. rdcu.be/eZ4Sd

Implications of successive blood feeding on #dengue virus inhibition by Wolbachia in Aedes aegypti mosquitoes @entomososwin.bsky.social @mallerybreban.bsky.social @brackneylab.bsky.social @chantalvogels.bsky.social @yaleemd.bsky.social
Implications of successive blood feeding on Wolbachia-mediated dengue virus inhibition in Aedes aegypti mosquitoes - Nature Communications
Dengue virus transmission by Ae. aegypti mosquitoes poses a significant public health threat, necessitating innovative control strategies. Here, the authors demonstrate that, while successive blood feeding increases earlier dengue virus dissemination, the inhibitory effects of Wolbachia remain strong, highlighting Wolbachia’s potential to disrupt dengue transmission under natural feeding conditions.

Blood-feeding patterns of #mosquitoes (Diptera: Culicidae) collected in an area of high arbovirus transmission in West-Central Brazil JMedEnt
Blood-feeding patterns of #mosquitoes (Diptera: Culicidae) collected in an area of high arbovirus transmission in West-Central Brazil
Abstract#mosquitoes target a wide range of vertebrate species for blood meal and study of these vector–host interactions enhances our knowledge of how vector-borne viruses are transmitted. In the last decades, West-Central Brazil has faced the emergence and reemergence of several arboviruses, with a great public health impact. In addition to the well-known #Aedes-borne viruses, such as dengue, Zika, and chikungunya, other arboviruses have spread throughout the country and constitute a continuous public health concern. We report results of blood meal analysis of #mosquitoes (Diptera: Culicidae) collected in urbanized areas of West-Central Brazil during a Zika virus surveillance between 2017 and 2018. Amplification and sequencing of mitochondrial DNA were used to determine vertebrate origin. A total of 284 blood-engorged #mosquitoes belong to 6 genera and 12 species were collected. Of these, we successfully identified blood meal in 146 (51.4%). Collections of blood-fed individuals were dominated by species of #Culex (65.8%) and #Aedes (25.4%). Overall, blood meal profiles demonstrated that humans were the main source (56.8%). Despite anthropophilic preferences, #Aedes aegypti also fed on domestic (12.5%) and wild mammals (8.3%). #Culex spp. showed an ornithophilic pattern. Humans made up 80% (n = 20) of blood meals from #Aedes albopictus while 20% (n = 5) were from horses. Our results expand the knowledge regarding the vertebrate species used as hosts by #mosquitoes in urbanized areas of Brazil. The variety of vertebrate species, including rodents, bats, and humans used by the local #mosquitoes, highlights the continuous risk for spillover events.

Glad to see this out!! It’s been bafflingly difficult to convince people that assuming mosquito transmission of Oropouche is a sloppy prior directly contradicted by all available evidence 🥲 and that, in turn, it’s a serious problem that we know so little about Culicoides paraensis distribution…
Colin Carlson@colincarlson.bsky.social · last yr.🦟🦠 NEW! We looked at every experiment going back to the 1960s, and found that mosquitoes are almost certainly not primary or secondary vectors of Oropouche virus - a common claim in both the scientific literature and public health communication. #EpiSky #IDSky 😷🧪 journals.plos.org/plosntds/art...
