Penn State Mosquitoes infected with the bacteria Wolbachia are more likely to become infected with West Nile virus and more likely to transmit the virus to humans, according to a team of researchers. "Previous research has shown that Wolbachia -- a genus of bacteria that live inside mosquitoes -- render mosquitoes resistant to pathogen infection, thereby preventing the mosquitoes from infecting humans with the pathogens," said Jason Rasgon, associate professor of entomology, Penn...

Climate Change Extends Mosquito Season, But With Smaller Populations
2013-09-10 07:19:17

April Flowers for redOrbit.com - Your Universe Online Climate change's influence on temperature and precipitation is varied, and a new study from the University of Arizona shows that the effect on the spread of West Nile virus might be just as wide-ranging. This suggests that public health efforts to control the virus will need to take a local, rather than global perspective. Cory Morin and Andrew Comrie, researchers from the University of Arizona, developed a climate-driven mosquito...

Researchers monitored WNV in mosquitoes in the field and in the lab, and observed how the virus is transmitted between generations In California Culex mosquitoes are considered to be the principle vectors of West Nile virus (WNV), which infects birds, humans, and other mammals during the summer. In addition, these mosquitoes may also serve as overwintering reservoir hosts as the virus is passed "vertically" from female mosquito to egg, then larva, and then adult. To find out how often...

Rainfall and temperature affect the abundance of two mosquito species linked to West Nile Virus in storm catch basins in suburban Chicago, two University of Illinois researchers report. Marilyn O´Hara Ruiz, a professor of pathobiology, led the study with graduate student Allison Gardner. The study was conducted using mosquito larvae collected from catch basins in Alsip, a southwest suburb. The researchers examined weather factors that influenced the levels of mosquito larvae in the...

A species of mosquito has been discovered breeding in the UK that has not been seen in the country since 1945. Populations of the mosquito, found across mainland Europe and known only by its Latin name Culex modestus, were recorded at a number of sites in the marshes of north Kent and south Essex in 2010 and 2011. The discovery was made by post-graduate student Nick Golding, and the mosquito was definitively identified by colleague Stefanie Schäfer of the Centre for Ecology...

New Threat Closes In On Iconic Galápagos Wildlife

  Renewed vigilance over the biosecurity of the Galápagos Islands is needed, based on new research on the risk posed by West Nile virus. Scientists from the Zoological Society of London (ZSL), the University of Leeds and the New York State Department of Health, together with the Galápagos National Park Service and University of Guayaquil, have been studying the disease threat posed by Islands' mosquito populations. They have discovered that a species of...

Scientists announced on Thursday that they had successfully sequenced the genome of the Southern house mosquito--the species of insect most responsible for the transmission of diseases such as West Nile virus, encephalitis, and elephantiasis. Writing in two separate papers published by the journal Science, a team of researchers from 39 universities in the United States and Europe reported that they had completely mapped the DNA of the Southern house mosquito, or Culex pipiens...

West Nile virus set the country abuzz when it rapidly spread from coast to coast just a few years after arriving in the United States. Most experts assumed birds were responsible for moving the virus across the country, but a paper published March 1 in the journal Molecular Ecology finds that smaller wings may be to blame. "This is one of the first studies to suggest that mosquitoes may have played a greater role in the rapid movement of West Nile virus," said Jason Rasgon, a professor at the...

Chemical ecologists in the Walter Leal lab at the University of California, Davis, have identified the dominant odor naturally produced in humans and birds that attracts the blood-feeding Culex mosquitoes, which transmits West Nile virus and other life-threatening diseases.  The groundbreaking research explains why mosquitoes shifted hosts from birds to humans and paves the way for key developments in mosquito and disease control. Entomology professor Walter Leal and postdoctoral...

St. Louis Encephalitis is a disease caused by the Culex mosquito borne St. Louis Encephalitis virus. It is related to Japanese encephalitis virus and is a member of the Flaviviridae subgroup. It mainly affects the United States and occasionally hits Canada and Mexico. The name goes back to 1933 within five weeks in autumn an encephalitis epidemic of explosive proportions broke out in the vicinity of St. Louis, Missouri. Over 1000 cases were reported and the National Institute of Health...

  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
