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...

New research by University of Warwick historian Dr Tim Lockley has found why yellow fever had a green bias in 19th century fever outbreaks in the southern states of the US. Almost half of the 650 people killed by yellow fever in Savannah Georgia in 1854 were Irish immigrants. Dr Tim Lockley´s study is based on four sources: the burial records of Laurel Grove cemetery; the records of the city´s Catholic cemetery; the minutes of Savannah´s Board of Health; and published lists...

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...

Vampire Jumping Spiders Are Picky Eaters

Do we now need to worry about vampire spiders? Well, only if you live in New Zealand and are a female mosquito. Picky eaters by any standards, E. culicivora jumping spiders, also known as vampire spiders, feed almost exclusively on female mosquitoes, which are filled with blood from their victims. Ximena Nelson from the University of Canterbury, New Zealand, says, “You can see from the diet when you find them in the field that there is a high number of mosquitoes in what they...

Researchers at the Johns Hopkins Bloomberg School of Public Health have, for the first time, shown that infection with dengue virus turns on mosquito genes that makes them hungrier and better feeders, and therefore possibly more likely to spread the disease to humans. Specifically, they found that dengue virus infection of the mosquito's salivary gland triggered a response that involved genes of the insect's immune system, feeding behavior and the mosquito's ability to sense odors. The...

Mosquito Repellant Could Be Frightening For Mosquitoes!

[ Watch the Video ] Repellant overwhelms their odor sensors, scaring them away In a small, narrow, temperature-controlled lab room at Vanderbilt University live some of the most deadly and dangerous animals in the world. "These are Anopheles mosquitoes that still think that they're in Central Africa. We won't tell them any different," says Laurence Zwiebel, professor of molecular biology and pharmacology. Anopheles gambiae mosquitoes can be killers. In warmer climates, the...

Aedes is a genus of mosquito found in tropical and subtropical zones. The name comes from the Greek aēdēs, meaning unpleasant, so called because of the diseases this mosquito transmits, which include dengue and yellow fever. There are presently some controversial moves afoot to abolish Aedes as a generic name and to replace it with Stegomyia. Currently, the Aedes aegypti genome is being sequenced by TIGR, The Institute for Genomic Research.

Aedes albopictus (Family Culicidae), the Asian Tiger Mosquito or Forest Day Mosquito, is characterized by its black and white striped legs and small, black and white body. It was native to south-east Asia, and occupied a habitat that spread from Madagascar eastward to New Guinea, and north to the latitude of Korea. The typical member of the Aedes albopictus has a length of about 5 mm. As with other members of the mosquito family, the female is outfitted with an elongated proboscis that she...

The mosquito is a member of the family Culicidae. These insects have a pair of scaled wings, a pair of halteres, a slender body, and long legs. Only the females of most mosquito species suck blood from other animals. Size varies but is rarely greater than 0.6 inch (15 mm). Mosquitoes weigh only about 0.03 to 0.04 grain (2 to 2.5 mg). They can fly at about 0.9 to 1.6 mph (1.5 to 2.5 km/h) and most species are nocturnal. Mosquitoes are believed to have evolved 170 million years ago during...
