Mar 29 2019 Female mosquitoes are known to rely on an array of sensory information to find people to bite, picking up on carbon dioxide, body odor, heat, moisture, and visual cues. Now researchers reporting in the journal Current Biology on March 28 have discovered how mosquitoes pick up on acidic volatiles found in human […]Continue Reading ...
Stanford infectious disease expert Desiree LaBeaud, MD, spends much of her time trying to understand interactions between humans and mosquitoes. “People don’t recognize that there are lots of different mosquito species and all the different mosquitoes have their own little mosquito behaviors,” LaBeaud told me recently. I was interviewing her for a feature story in […]Continue Reading ...
This photomicrograph of a blood smear contains a macro- and microgametocyte of the Plasmodium falciparum parasite. Credit: Wikipedia. Mosquitoes that landed on surfaces coated with the anti-malarial compound atovaquone were completely blocked from developing Plasmodium falciparum (P. falciparum), the parasite that causes malaria, according to new research led by Harvard T.H. Chan School of Public […]Continue Reading ...
Mosquitoes can hear over distances much greater than anyone suspected, according to researchers at Cornell and Binghamton University. Their findings were published in the journal Current Biology. Until now, scientists believed that organisms required eardrums for long-range hearing, and that the feathery antennae with fine hairs that mosquitoes and some insects use to hear only […]Continue Reading ...
Dec 13 2018 When the West Nile virus (WNV) was initially isolated in two patients at a Queens, N.Y., hospital in the summer of 1999, it would have been hard to anticipate how quickly one common species of house mosquito, Culex pipiens, would help begin to spread the virus throughout the western hemisphere. Bite-by-bite, coast-to-coast, […]Continue Reading ...
Mosquitoes are the world’s deadliest animals, killing thousands of people and causing millions of illnesses each year. To be able to reproduce and become effective disease carriers, mosquitoes must first attain optimal body size and nutritional status. A pair of researchers at the University of California, Riverside, have succeeded in using CRISPR-Cas9, a powerful tool […]Continue Reading ...
Malaria parasites have evolved to be most infectious at the time of day when mosquitoes feed, to maximize the chance of being spread, research shows. The finding explains why people with the disease experience regular bouts of fever. These occur as the parasites that cause malaria replicate in the bloodstream of infected people or animals, […]Continue Reading ...
By Dr Ananya Mandal, MDAugust 13, 2018 Genetically modified mosquitoes Researchers at the Imperial College’s South Kensington campus have successfully created genetically modified mosquitoes that would stop them from multiplying and spreading dreaded diseases such as malaria, Dengue, Chikungunya and Zika that kill millions worldwide annually.

Outbreaks of mosquito-borne illnesses like yellow fever, dengue, Zika and chikungunya are rising around the world. Climate change has created conditions favorable to mosquitoes’ spread, but so have human travel and migration and accelerating urbanization, creating new mini-habitats for mosquitoes. In today’s Nature Microbiology, a large group of international collaborators combined these factors into prediction […]Continue Reading ...
The anopheline mosquitoes that carry malaria were present 100 million years ago, new research shows, potentially shedding fresh light on the history of a disease that continues to kill more than 400,000 people annually. “Mosquitoes could have been vectoring malaria at that time, but it’s still an open question,” said the study’s corresponding author, George […]Continue Reading ...
Researchers at the University of Arizona have discovered a way of preventing mosquito eggs from hatching, potentially paving the way for drugs that could serve as “birth control” within mosquito populations. Vera Larina | Shutterstock Lead author Dr. Jun Isoe and colleagues hope the approach may provide a way of interrupting mosquito reproduction and reducing […]Continue Reading ...
Some people tend to be the targets of mosquitoes more than others. A new study titled, ‘Improved reference genome of Aedes aegypti informs arbovirus vector control’, by researchers at the QIMR Berghofer Medical Research Institute has found that the genetic make-up of these individuals make them attractive to mosquitoes and so they get bitten more. […]Continue Reading ...
Host decoy traps which mimic humans or cattle by combining odor, heat and a conspicuous visual stimulus could be effective at measuring and controlling outdoor-biting mosquitoes in malaria endemic regions, according to a study published in the open access journal Parasites & Vectors. While indoor-biting mosquitoes, which are important vectors for malaria, are being controlled […]Continue Reading ...
The ears of male mosquitoes amplify the sound of an approaching female using a self-generated phantom tone that mimics the female’s wingbeats, which increases the ear’s acoustic input by a factor of up to 45,000, finds a new UCL-led study. The researchers were studying disease-carrying mosquitoes, and hope their findings, published in Nature Communications, could […]Continue Reading ...
July 18, 2018 A virus responsible for an illness outbreak in Venezuela is spreading to other parts of the Americas, says a University of Florida scientist who is closely monitoring the Mayaro virus. Most recently, the virus was found in a child in Haiti in 2016. Even though the virus hasn’t infected anyone in Florida […]Continue Reading ...
