Vector mosquitoes are well-adapted to habitats in urban areas, including belowground infrastructure such as stormwater systems. As a major source of larval habitat in population centers, control of larval populations in stormwater catch basins is an important tool for control of vector-borne disease. Larval development and adult phenotypes driving vectorial capacity in mosquitoes are modulated by the larval gut microbiota, which is recruited from the aquatic environment in which larvae develop.

- Mosquito-borne diseases like West Nile Virus are increasing in North America, and accurately modeling mosquito population density remains a significant challenge, crucial for predicting disease transmission risks.
- A new weather-driven Ordinary Differential Equation (ODE) model has been developed to study mosquito population biology, incorporating factors like temperature, daylight, competition, and aquatic habitats.
- The model also evaluates the impact of precipitation on mosquito mortality and assesses the effectiveness of various insecticide strategies to help reduce mosquito populations and mitigate disease risks.
Background: During the COVID-19 pandemic, there was a rapid adoption of telehealth care services as a public health strategy to maintain access to essential health care. In Australia, there has been increasing optimism for the expansion of telehealth services. However, little is known about the patterns and determinants of telehealth adoption among older adults, with concerns that an expansion of telehealth services may only be of benefit to those who already have better access to health care.

In this study, susceptibility to S-methoprene was evaluated in Culex pipiens, a globally important vector species. Populations from 14 sites throughout the Chicago area with a long history of S-methoprene use and two sites with minimal use in Wisconsin were examined.

- Scientists studied how tick bites affect skin to understand diseases caused by ticks.
- They found many genes that behaved differently in skin right after a tick bite compared to skin taken later, showing how the body reacts over time.
- The research could help identify markers to predict how a person will respond to tick bites and help with treatments in the future.
