The Mosquito Paradox

It seems like common sense: Reduce insect populations, and insect-borne diseases will decline as well. But a new study of dengue, a viral disease transmitted by Aedes mosquitoes, suggests the opposite. Controlling mosquitoes may result in more cases of dengue hemorrhagic fever (DHF), a rare and sometimes fatal disease caused by the virus.

Researchers think that tens of millions of people in the tropics become infected with the dengue virus each year. The pathogen can spur dengue fever, which is marked by agonizing muscle and joint pains but is rarely fatal

Most people in hot places--or even just hot weather--are troubled by mosquitos. What is an annoyance in some parts of the world, however, can be fatal in others. In this stuty, the scientists point out that it is necessary to search for more effective repellents, one of which is introduced in this article, lasting a record 85 days!

Mosquitoes can carry many blood-borne diseases, like malaria and yellow fever. This study follows the introduction of: bed nets designed to stop mosquitoes in their tracks, which are undergoing large-scale trials in India and Tanzania.

Analyzing the control of mosquito-borne diseases by a dominant lethal genetic system

newsdigg submitted, created time 1 year 6 months (www.pnas.org)

Motivated by the failure of current methods to control dengue fever, we formulate a mathematical model to assess the impact on the spread of a mosquito-borne viral disease of a strategy that releases adult male insects homozygous for a dominant, repressible, lethal genetic trait

Genome of yellow fever/dengue fever mosquito sequenced

Dolly submitted, created time 1 year 6 months (www.eurekalert.org)

Developing new strategies to prevent and control yellow fever and dengue fever has become more possible with the completion of the first draft of the genome sequence of Aedes aegypti mosquito by scientists led by Vishvanath Nene at The Institute for Genomic Research (TIGR) and David Severson at the University of Notre Dame. The genome is the complete set of genetic material including genes and other segments of DNA in an organism.
