Mosquito
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. The females of most mosquito species suck blood from
other animals.
In the English language, the word Mosquito (Span., little fly) dates
back to 1583; The word was adopted to replace the term "biting
flies" to prevent confusion with the house fly. It is derived from
the word musca (Latin fly, cf. Skt maksh) and is related to the
Italian moschetta and
the French moustique.
The female mosquito (in almost all species) sucks the blood of
mammals, including humans. Mosquito bites often swell up hours after
happening, causing a red ringed white bump about a centimeter in
diameter. This bump can itch for days and over-scratching the bite
can cause it to bleed. Mosquito bites can transmit diseases, such as
malaria and West Nile Virus, so authorities in many areas take
measures to reduce mosquito populations through pesticides or more
organic means. An easy way to reduce mosquito populations in a
residential area is the removal of standing water (where mosquitoes
breed), and the use of repellents, such as DEET.
Mosquitoes and health: In much of the world, mosquitoes are a major public health problem;
they are estimated to transmit disease to more than 700 million
people annually, and will be responsible for the deaths of about 1
in 17 people currently alive. In the United States and other
temperate countries, mosquito bites are mostly just a nuisance.
Mosquito control and integrated mosquito management: There are two kinds of mosquito control: large, organized programs
to reduce mosquito populations over a wide area, and actions an
individual can take to control mosquitoes with respect to themselves
and their own property.
Organized mosquito control programs today draw on the principles of
integrated pest management. An integrated mosquito control program
typically includes the following measures, all guided by
surveillance of mosquito populations and knowledge of the mosquito
life cycle: [2]
* source reduction - the removal of mosquito breeding habitats
* habitat modification - manipulating habitats to reduce breeding
* biocontrol - introducing natural predators of mosquitoes
* larvicide - using pesticides to reduce larval populations
* adulticide - using pesticides to reduce adult populations
Since many mosquitoes breed in standing water, source reduction can
be as simple as overturning an old tin can, or can be as complex as
permanently draining marshes. Much source reduction is a matter of
education. For example, homeowners can eliminate mosquito breeding
grounds by removing unused plastic pools, old tires, or buckets; by
clearing clogged gutters and repairing leaks around faucets; by
regularly changing water in bird baths; and by filling or draining
puddles, swampy areas, and tree stumps. Eliminating such mosquito
breeding areas can be an extremely effective and permanent way to
reduce mosquito populations without resorting to insecticides. |
