how do musquitoes find human beings anyhow and try to bite them. How mosquitoes detect human beings? do mosquitoes like human blood?

When people and animals breathe, they exhale an invisible mixture of carbon dioxide (CO2) and Octenol (a type of alcohol) along with a trace of moisture. Mosquitoes and other biting insects have ultra-sensitive receptors which can detect the presence of these chemicals, or kairomones, from almost 100 feet away. The attraction is so powerful, they immediately fly toward the source of the chemicals.\n\nMoreover, circulating blood in animal and human targets radiates body heat. Mosquitoes also have sophisticated heat sensors to help them locate blood, their food supply. In effect, mosquitoes become heat-seeking missiles, following both exhaled gases and body heat directly to their target. Within 30 feet, mosquitoes can actually see their victims. When they arrive, they fly around the victim to find landing sites where blood is closest to the surface.

Why do mosquitoes bite?\nMosquitoes belong to a group of insects that requires blood to develop fertile eggs. Males do not lay eggs, thus, male mosquitoes do not bite. The females are the egg producers and "host-seek" for a blood meal. Female mosquitoes lay multiple batches of eggs and require a blood meal for every batch they lay. Few people realize that mosquitoes rely on sugar as their main source of energy. Both male and female mosquitoes feed on plant nectar, fruit juices, and liquids that ooze from plants. The sugar is burned as fuel for flight and is replenished on a daily basis. Blood is reserved for egg production and is imbibed less frequently.

When a mosquito first bites, he releases a chemical that keeps some of the clotting factors from taking effect. No clotting factors=no coagulation.

An old camping trick was to chew on the end of a couple of matches.  No kidding, I know y'all think I'm pulling your leg, but seriously, the kitchen matches with the white dot on the tip of the red.  Something about the sulphur in the matches makes you secrete something that repels mosquitos.  Personally, I've never tried it, but I have a friend that swears by it.

to find food, attract/find mates, detect danger/predators, identify other animals' territory\n\n-find food e.g. shark smells blood from far away, know that there's weak prey, swims to prey and devours it\n\n- attract/find mates e.g. some female animals have a scent that tells the males they are mature and ready to mate\n\n- detect danger e.g. breeze carries scent of a predator to a deer, deer is alerted, whole herd runs away\n\n- identify territory e.g. wolves mark territory by peeing on trees... ><\n\n :) hopefully this helped

it's becoz some (like maleria for e.g.) can survive in mosquitoes and mosquitoes act as complementary to complete their cycle.\n\nothers (HIV for e.g.)either would not survive in them or meet a dead end..

There are three reasons listed, at the site provided below, why it is impossible for a mosquito to transfer HIV.\n\nhttp://www.rci.rutgers.edu/~insects/aids.htm\n\nHIV is a virus, and, as we’ve mentioned in other questions and answers, HIV doesn’t do so well outside the human body. Once in the mosquito, the HIV would die very quickly. The mosquito never becomes HIV-infected, and nobody has ever become HIV-infected from a mosquito bite.\n\nhttp://hivinsite.ucsf.edu/insite?page=ask-05-11-09-02\n\nWhen a mosquito ingests HIV-infected blood, the virus dies (unlike malaria, which lives in the mosquito's intestinal system and is re-injected out in its oral fluid).  The mechanical procedure of feeding wipes blood off of the mosquito's proboscis--it is retracted into a sheath.  Even in geographical areas where mosquitoes proliferate, HIV is still seen only in sexual or blood-sharing adults. \n\nhttp://www.ode.state.or.us/opportunities/grants/hklb/hiv-aids/hivqandas.aspx

Well, aliens do exist, I'm pretty sure our traditional vampire does not. But, if he did get to bite an alien I'm not sure if his "blood" would react  exactly same way as humans. Even if it did, the planet would not be a vampire planet. Earth is not, now is it? That's assuming vampires do exist just to play along with the question. This is a good question btw.

You're correct about its mouth size--too small to bite humans. It feeds on small insects or the corpses of larger ones. It has a penis, which makes it different from spiders. In fact, the Daddy Longlegs is not technically a spider, although it is an arachnid. I even learned its mating dance. But what I didn't learn was the answer to your question. I ran out of new source material. Despair loomed. Failure before Cecil's eyes is damning indeed.\n\nThen, in the distance, a glimmer of hope. I had visited a slew of arachnid websites, drawing blanks. In desperation, I E-mailed various names from the sites. Just when all seemed lost, Herman Vanuytven came forth from the Arachnology Home page (http://www.ufsia.ac.be/Arachnology/Arachnology.html). Herman's response:\n\n"The problem with the 'Daddy Longlegs' is that the name is used for several kinds of animals, 2 of them arachnids:\n\n1) The family Phalangiidae (a part of the opilionids [harvestmen], a different order than spiders)\n\n2) a spider: Pholcus phalangioides\n\nNumber one doesn't have poison glands. Number two has poison glands but as far as is known in the scientific world, nobody has ever been bitten by one of them. It's not sure if the poison has ever been investigated since there was no need for it."\n\nConclusive proof has yet to be determined.

Look for information on the Human Bot Fly, there are a lot of images, and they are nasty.\nThe genus Dermatobia contains only one species, D. hominis, the only species of bot fly that attacks humans (in addition to other primates). It is also known as the torsalo. In this species the fly's eggs are vectored by mosquitoes and muscoid flies; the female Dermatobia captures the fly and attaches its eggs to the body of the fly, then releases it. The eggs hatch either while the mosquito is feeding and the larvae may use the mosquito bite area as the entry point, or simply drop off the muscoid fly when it lands on the skin. They develop inside the subcutaneous layers, and after approximately 8 weeks they drop out to pupate for at least a week, typically in the soil. The adults are small gray flies resembling a blowfly.\n\nThis species is native to the New World tropics, though it is not abundant enough (nor harmful enough) to ever attain true pest status. Since the fly larvae can only survive the entire eight week development if the wound does not become infected, it is rare for patients to experience infections, unless they kill the larva without removing it completely (below). It is even possible that the fly larva may itself produce antibiotic secretions that help prevent infection while it is feeding.

Fleas are parasites, because they live on rats and do not benefit the rats.\n\nFleas carry many communicable diseases, most  notably, bubonic plague, murine plague, murine typhus, and tularemia. \n\nThere are many other diseases spread by parasites. Rabies can be spread by bats that drink animal blood (vampire bats.) Mosquitoes probably cause more death from communicable diseases than any other animal. \n\nCheck the World Health Organization (WHO) infectious disease page and search for "insect vectors" for more, though insects are not the only parasites that spread disease.

This is as Serious Question, especially when tackling West Nile Virus, Malaria, Dengue, all vector borne disease.\n\nGoogle this on the web, there was a recent report about Rain and Butterflies (Slightly larger than bugs) They are also frighten of rain, as it is dangerous to them, the relative size of the water droplet, would harm them.\n\nBugs, usually try to hid from the rain, going into overhangs,  under large leaves, seeking shelter when they can find it.\n\nGood Question.  Next point, ever wonder where Flies goes after dark.

Take live snails to the mall, blindfold passersby, and feed them snails.  Hypothesis, snails taste gross. Prove or disprove. Discuss.  Alternate hypothesis, life gives life.  If snails ate humans, then humans would kill snails.  Since they don't eat humans, there is no good rational for killing them.  Unless you have too much salt and are bored :)

If mosquitos could transmit HIV, we would all have had it by now.  Mosquitos live in every environment and everyone has been bitten at least once.  \n\nHIV is much more common than West Nile - there is not a big number of mosquitos carrying West Nile.\n\nMosquitos do not bite one person, then another, then another.  They bite one person then they have to rest & digest.  \nBecause they are digesting a blood borne pathogen that does not infect them - it is not re-transmittable.\nWest Nile is a very different virus than HIV and infects the mosquito - making it tranmissable.\n\nIf any miniscule amount of HIV infected blood is on the mosquito's mouthparts, then the virus would die on contact with the air.
