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 ...
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.

July 16, 2018 Entomologists at the University of California, Riverside have received a five-year grant of $2.44 million from the National Institute of Allergy and Infectious Diseases, or NIAID, to investigate the role hormones play in the female mosquito’s ability to use human blood for egg production. Vector mosquitoes need vertebrate blood to develop each […]Continue Reading ...
By Dr Ananya mandal, MD,June 25, 2018 Oxitec, a company based in the UK, have developed what they call “Friendly mosquitoes”. These are bio-engineered male mosquitoes that would mate with the female to result in baby mosquitoes that die before they reach adulthood. This death before adulthood would be only for the female offspring. Oxitec’s […]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 ...
FRIDAY, June 21, 2018 — Aedes mosquitoes in California can spread the Zika virus, researchers report. Laboratory studies have shown that several species of Aedes mosquitoes can transmit Zika, but whether the same species in different regions could spread the virus was unclear. Zika is a relatively mild illness for most people, but it can […]Continue Reading ...
June 19, 2018 Researchers at the University of Waterloo may have discovered a new, pesticide-free way to limit mosquito populations in some area and reduce the spread of the West Nile virus. Waterloo researcher Brad Fedy discovered that introducing hungry minnows into bodies of water where mosquitoes breed results in the minnows feeding on mosquito […]Continue Reading ...
