A new study found that higher temperatures reduce the effectiveness of natural mosquito repellents by desensitizing their pain receptors. This means mosquitoes may find these substances less irritating in hotter weather, potentially leading to increased bites and disease transmission.
Researchers at Johns Hopkins Bloomberg School of Public Health discovered a molecular quality-control system in Anopheles mosquitoes that can be targeted to disrupt malaria parasites. Disrupting the prefoldin chaperonin system reduced mosquitoes' ability to host and transmit malaria parasites, killing about 60% of them.
Researchers have identified novel mosquito repellents with high success rates from natural sources, including food and flavoring materials. The team's machine learning-based cheminformatics approach also pinpointed pyrethroid analogs up to 100 times more effective than existing industry standards.
A new study led by La Jolla Institute for Immunology scientists found that children who experience multiple dengue virus infections develop protective T cells, which help fight the virus. These T cells appear to be key to dengue virus immunity and may inform the development of a vaccine that prompts a similar response.
Researchers at Purdue University are studying mosquito antennae to develop acoustic sensors that can detect natural disasters like earthquakes and tsunamis. By mimicking the unique structure of these antennae, they hope to create more sensitive sound-detection technology.
The reemergence of dengue virus serotype 3 (DENV-3) in Brazil could worsen fresh outbreaks as the population is not immunized against this serotype. Researchers found a rise in DENV-3 cases since late 2023, with 31 blood samples testing positive for the virus.
A recent study identifies temperature and rainfall as key drivers of the global increase in dengue cases, offering actionable strategies for mitigating the disease's impact. The research found that dry season length variation is a decisive factor explaining contrasting effects of rainfall on dengue transmission.
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.
