If we have to make #malaria a thing of the past for future generations, let’s reimagine the fight against this disease by leveraging cutting-edge research such as #GeneDrive. #WorldMalariaDay

Thank you so much, glad to hear my cartoony mosquitoes bring joy and whimsy 🦟

Exposure to cold and heat could affect adolescents’ mental health, according to a study led by #ISGlobal.

The research highlights how exposure to climate-related temperature influences psychiatric symptoms such as anxiety, depression, and attention problems.

The production of a large number of mosquitoes and reliable sex sorting before release are key challenges when applying the sterile insect technique. This 2020 study aimed to evaluate the potential use of the FAO/IAEA larval rearing unit for Aedes aegypti 🧪

Aedes aegypti larval development and pupal production in the FAO/IAEA mass-rearing rack and factors influencing sex sorting efficiency Abstract The production of a large number of mosquitoes of high biological qualities and reliable sex sorting before release are key challenges when applying the sterile insect technique as part of an area-wide integrated pest management approach. There is a need to fully evaluate the production capacity of the equipment developed in order to plan and maintain a daily production level for large-scale operational release activities. This study aimed to evaluate the potential use of the FAO/IAEA larval rearing unit for Aedes aegypti and the subsequent female contamination rate after sex sorting with a Fay–Morlan glass separator. Trays from each rack were tilted and their contents sorted either for each individual tray or after mixing the content of all trays from the rack. The pupal production and the female contamination rate were estimated with respect to day of collection, position of the tray, type of pupae collection, and sorting operator. Results showed significant daily variability of pupal production and female contamination rate, with a high male pupal production level achieved on the second day of collection and estimated female contamination of male pupae reached around 1%. Neither tray position nor type of pupae collection affected the pupal production and female contamination rate. However, the operator had a significant effect on the female contamination rate. These results highlight the need to optimize pupal production at early days of collection and to develop a more effective and automated method of sex separation.

We're talking about vector surveillance in this week's med/vet entomology lab. I had trouble finding nice, clean schematics for the different trap types, so I created this slide showcasing different traps used to monitor adult #mosquitoes! 🦟 🧪
An slide titled '(SOME) TRAP TYPES - ADULT MOSQUITOES' that displays four types of traps used for capturing adult mosquitoes, with illustrations and brief descriptions for each. UV Light Trap: A hanging trap with a light source and collection container. The text explains that UV light attracts adult female and male mosquitoes of all species. A fan and collection container are included, and the diagram notes 'wind' as a directional feature. CO2 Trap: Depicted as a vertical structure with a container emitting CO2, a fan, and a collection container at the base. The text indicates that it targets adult female mosquitoes of all species by mimicking host respiration. BG Sentinel Trap: Shown as a black cylindrical structure with an intake funnel (flap that opens and closes), an attractant source, a collection container, and a motorized fan. It targets adult mosquitoes, primarily females, of all species. Gravid Trap: Illustrated as a rectangular bin with bait-infused water, a collection container above, and a motorized fan. A diagram of a mosquito indicates that it primarily targets adult, blood-fed mosquitoes, especially those of the Culex species.
