The dengue virus uses its envelope protein to capture human plasmin, enhancing the permeability of the mosquito midgut. This interaction is crucial for viral infection, and understanding it could lead to innovative approaches to tackle vector-borne viruses.
Researchers found that mosquitoes drink blood to survive droughts, not just water, allowing them to bite more frequently when rain comes. This increases the risk of spreading diseases like malaria, dengue fever, and Zika during dry periods.
A study found that El Niño is associated with increased larval infestations of Aedes aegypti mosquitoes in open-air disused containers in São Paulo state. The index of positive containers rose by 1.30 in El Niño years compared to neutral or weak events.
Climate change is responsible for 19% of the current dengue burden, with a potential to spark an additional 40%-60% spike by 2050. A study found that moderating global warming would also moderate climate impacts on dengue infections.
Scientists are exploring the use of fluralaner, an insecticide used to treat pets, as a larvicide against mosquitoes and flies. The study found that fluralaner is effective in controlling mosquito larvae for five weeks and midge larvae for eight weeks.
A new study by the University of Exeter and Wageningen found that Asaia bacteria accelerate the development of mosquito larvae, potentially boosting mass-rearing schemes. This could lead to more effective global health programmes against diseases like dengue, yellow fever, and Zika.
Increased malaria cases from mosquitoes transported by air have been reported in France and a European systematic review, highlighting the risk of Odyssean malaria. Locally-acquired infections remain constant, with more cases being reported since 2011.
The invasive tiger mosquito expands its host range as it spreads across regions, with a greater diversity of hosts in the invasive range. The mosquito's ability to adapt to new environments and act as a bridge vector for pathogens increases the risk of disease transmission.
Researchers at the University of Nottingham uncover key regulators of malaria parasites' cell division, revealing NEK1 as a potential drug target. The study aims to find new therapeutic targets for controlling malaria transmission.
A study published in the journal Insects found that hemp leaf extract containing cannabidiol (CBD) is effective in killing mosquito larvae, including those resistant to typical insecticides. The research suggests CBD's potential as a safe and sustainable alternative for controlling mosquito populations.
A new study by the UK Centre for Ecology & Hydrology predicts high-risk towns across Europe for dengue fever outbreaks, with southern France and northern Italy being most affected. The research uses advanced high-resolution modeling to provide daily risk assessments for each area.
Researchers at the University of Kansas are analyzing noninfectious mosquito saliva to understand how it affects the immune system and changes at a molecular level. The goal is to identify specific proteins that can serve as candidates for vaccine development.
Researchers have identified a specific immune cell type and signaling pathway that leads to itching in people with allergies. By targeting this pathway, they hope to develop novel therapeutics for preventing allergic responses and sensitization.
Researchers at Heidelberg University developed an AI-supported method to map mosquito populations by analyzing satellite and street view images. This approach helps assess environmental conditions favoring Aedes aegypti presence, enabling targeted disease control measures.
Researchers at the University of Washington have uncovered surprising details about mosquito mating, revealing that males can visually lock on to female targets in a crowded swarm. The team's findings could lead to the development of new mosquito traps specific to malaria-carrying species.
