Vector competence for Oropouche virus: A systematic review of pre-2024 experiments Oropouche virus has recently become an urgent threat to public health in Central and South America. OROV is mainly transmitted by biting midges; however, some public health agencies and scientific sou...

🦟🦠 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 😷🧪

Modelling the effects of diurnal temperature variation on malaria infection dynamics in mosquitoes - Communications Biology Mechanistic modelling of the effects of diurnal temperature variation on Plasmodium falciparum sporogony indicates this variation is important in the laboratory, but further validation is required to ...

As we try to understand how climate change impacts malaria @isaacstopard.bsky.social looked how daily temperature fluctuations impact development in mosquitoes. Quite a bit it seems, but still unclear in wild mosies. Lovely data from Antoine Sanou but we need more! www.nature.com/articles/s42...

The Sweetest Snack: Research Details Mosquitoes' Nectar Preferences Mosquitoes drink nectar (not just blood), but do they prefer certain plants? A new research review shows mosquitoes do indeed have nectar preferences.

Mosquitoes drink nectar (not just blood), but do they prefer nectar from some plants over others? A new research review shows mosquitoes do indeed have nectar preferences, which researchers say can inform placement of attractive targeted sugar baits in mosquito control efforts.

Our study ‘The global human impact on biodiversity’ is out in Nature!

Through an unprecedented synthesis (2133 studies!) we show that humans are not only shrinking species numbers—but reshaping entire communities across the planet. 🌍🌐🐟🌿🪲

Larval competition between the invasive Aedes aegypti (Diptera: Culicidae) and the Caribbean endemic Aedes mediovittatus (Diptera: Culicidae) from Puerto Rico, USA Abstract. Competition between mosquito species during the larval phase is a well-established mechanism structuring container mosquito communities, with inv

🦟🧪Our paper on larval competition between Aedes aegypti and Aedes mediovittatus, a Caribbean endemic, is out! In it, we show that the endemic appears to be the superior competitor, and this may explain why Ae. aegypti is restricted to cities on the island. academic.oup.com/jme/article-...

A screenshot of the Review article titled '(Limited) Predictability of thermal adaptation in invertebrates' by James deMayo and Gregory Ragland

Evolutionary genetics studies are often used to predict how species may adapt to climate change. In their recent Review, deMayo & Ragland discuss why these studies are only somewhat useful for predicting how invertebrates will respond to climate change

Mapping the global prevalence, incidence, and mortality of Plasmodium falciparum and Plasmodium vivax malaria, 2000–22: a spatial and temporal modelling study The unprecedented investment in malaria control since the early 2000s has averted an enormous amount of malaria burden. However, case incidence rates in Africa have flattened, and with a rapidly growi...

Results show ongoing plateau in malaria infection prevalence & case incidence in sub-Saharan Africa, with no consistent improvement since 2015. But malaria deaths continued to decline in sub-Saharan Africa after 2015, except for the COVID-19-impacted yrs of 2020–22

CDC cuts expected to devastate Epidemic Intelligence Service, a ‘crown jewel’ of public health Members of the CDC's Epidemic Intelligence Service were warned Friday that many of them were about to be fired

Doing the unthinkable: The deep cuts to the #CDC's workforce today are expected to decimate the Epidemic Intelligence Service, a program that has trained public health rapid responders for decades.
Envy of the world. Poof!

CDC cuts expected to devastate Epidemic Intelligence Service, a ‘crown jewel’ of public health Members of the CDC's Epidemic Intelligence Service were warned Friday that many of them were about to be fired

They're legendary disease detectives: The CDC's Epidemic Intelligence Service. Very little may be left of it after today, writes @helenbranswell.bsky.social www.statnews.com/2025/02/14/t...

This includes one of my former graduate students. Sad. I am lost for words.

Mosquitoes Adapt to a Warming Environment Genetic alterations may help mosquitoes adjust to climate change, shifting the distribution of mosquito-borne disease in a warming planet.

Excellent coverage of our recent work finding that mosquitoes may be able to adapt to warming! www.the-scientist.com/mosquitoes-a...

Final day at #EntSoc24. My team and @SilvieHuijben's team are enjoying the science talks, and are happy to meet old and new friends. Thanks @entsocamerica.bsky.social for organizing a wonderful conference in our hometown. 🌵 ☀️
