"Mosquito"The word Mosquito "mosca and ito" Is a Spanish orPortuguese word meaning "little fly" or “long-legged”Anopheles -Greek mean hurtful-Latin mean four spots(4 dark spots on the wings)
•It is a common flying insect that is foundaround the world.•It is the deadliest animals on Earth.•On average, a female mosquito will live 2-3weeks.•Can fly about 1 to 1.5 miles per hour (1.6-2.4k/h).•Salt marsh mosquitoes may travel up to 100miles from their larval breeding habitat
• A mosquitos wings beat 300-600 times per second• Only female mosquitoes bite.• An adult mosquito may live 5-6 months• Mosquitoes can detect carbon dioxide from 75 feet away• The size depends upon the population of the larva instanding water and the amount of food available to the larvato eat. With the size of a mosquito varying, adults dontnormally grow larger than 16 millimetres and weigh 2.5 mg.• Mosquitoes prefer children to adults
•Mosquitoes must have water to lay their eggsand the eggs need water to HATCH - somespecies lay their eggs in moist soil (notstanding water)•One female floodwater mosquito has apotential to lay 200 eggs per batch
•Over 2,700 to 3500 species of mosquitoes in the world.
About 200 species areavailable in the United Statesof which 77 species are inFlorida alone.
Mosquito BiologyMosquitoes develop through 4 different stagesduring their life: egg, larva, pupa, and adult.Pupal MosquitoLarval MosquitoMosquito Egg
•Have two wings, but unlike other flies, have scales.•Female mosquitoes mouthparts form a longpiercing-sucking slender - Proboscis.
•At its end there are two pairs of cutting Stylets thatslide against one another to slice through the skin.
•Inside the proboscis are two hollow tubes, one thatinjects saliva into the microscopic wound and onethat withdraws blood.
How does it find its victim:•Sight•Visual sensors -- wearing clothing thatcontrasts with the background, andmoving while wearing that clothing.•Anything moving is "alive", and thereforefull of blood.•Smell
•Heat sensors –(infrared light), (heat light), can find warm-blooded mammals and birds very easily once theyget close enough.•Chemical sensors –Perspiration and body odor.Can sense carbon dioxide and lactic acid from75-100 feet (36 meters) away. Just anymammal or bird which gives off these gases aspart of its normal breathing. Certain chemicals in sweat also attractmosquitoes (people who dont sweat dontget nearly as many mosquito bites).
Once through the skin:The proboscis begins probing for a tiny bloodvessel. If it does not strike one on the first try,the mosquito will pull back slightly and tryagain at another angle through the same holein the skin.The mosquitos saliva includes a combinationof anti-hemostatic and anti-inflammatoryenzymes that disrupt the clotting process andinhibit the pain reaction.
•If she is disturbed, she will fly away.Otherwise, she will remain until shehas a full abdomen. If the sensorynerve to her abdomen is cut, shewould keep sucking until she burst.
Mechanism of itch:•After she bites, some saliva remains in the wound•The proteins from the saliva evoke an immune responsein the body•The area swells (wheal)•Starts itching (a response provoked by the saliva)•Eventually, the swelling goes away, but the itch remainsuntil the immune cells break down the saliva proteins.
10 Ways to Guarantee Youll GetMosquito Bites:1.Keep breathing2.Skip the shower3.Run around4.Sweat a lot5.Stay warm6.Dress in dark colors7.Put perfume or cologne8.Use alpha hydroxy products on your skin.Lactic acid, which our bodies produce naturally, is a big draw formosquitoes. It just so happens that many skin care products contain lacticacid, too9.Dont change your socks10.Drink beer and eat limburger cheese (A soft white cheese with a verystrong odor and flavor).11.If you eat bananas, you are more likely to be bitten
Something with this manysensors sounds more like amilitary aircraft than an insect.
Epidemiology Of MalariaNearly 1 million people out of the 250 milliondiseased cases die of malaria every year(World Health Organization)Of the total numbers, 80% of estimatedmalaria deaths occur in just 14 countries andapproximately 80% of estimated cases occurin 17 countries.
•Major impact of the disease is almostentirely on the developing countries.• Economic burden of malaria: It takes off1.3% from the economic growth of someAfrican countries.
