Hey guys, a small Insects World is full of adventure and different but
sometimes for humans Can Harmful, if U thinks what can a small insect will to
your body then you’re wrong, they can kill you.

Let's know about one theme and most dangerous of theme Mosquito. Yes Mosquito
is the most dangerous insect on Earth and even Mosquito is also in the list of
most Harmful for man living things on Earth and its also top in that. Females
of most species are ectoparasites, whose tube-like mouthparts (called a
proboscis) pierce the hosts' skin to consume blood. The word
"mosquito" (formed by mosca and diminutive -ito) is Spanish for
"little fly".
Thousands
of species feed on the blood of various kinds of hosts, mainly vertebrates,
including mammals, birds, reptiles, amphibians, and even some kinds of fish.
Some
mosquitoes also attack invertebrates, mainly other arthropods. Though the loss
of blood is seldom of any importance to the victim, the saliva of the mosquito
often causes an irritating rash that is a serious nuisance.
Much more serious
though, are the roles of many species of mosquitoes as vectors of diseases.
A mosquito can drink up to three times its weight in blood. Don't worry, though. It would take about 1.2 million bites to drain all the blood from your body.
In
passing from host to host, some transmit extremely harmful infections such as
malaria, yellow fever, Chikungunya, West Nile virus, dengue fever, filariasis,
Zika virus and other arboviruses, rendering it the deadliest animal family in
the world.
The oldest known mosquito with an anatomy similar to modern species was
found in 79-million-year-old Canadian amber from the Cretaceous.An older sister
species with more primitive features was found in Burmese amber that is 90 to
100 million years old. Two mosquito fossils have been found that show very
little morphological change in modern mosquitoes against their counterpart from
46 million years ago. These fossils are also the oldest ever found to have
blood preserved within their abdomens. Despite no fossils being found earlier
than the Cretaceous, recent studies suggest that the earliest divergence of
mosquitoes between the lineages leading to Anophelinae and Culicinae occurred
226 million years ago.
The
Old and New World Anopheles species are believed to have subsequently diverged
about 95 million years ago.There are more than 3,500 species of mosquitoes.
About 175 of them are found in the United States, with the Anopheles
quadrimaculatus, Culex pipiens, Aedes aegypti and Aedes albopictus (Asian tiger
mosquito) among the most common. The Anopheles is a malaria carrier, and the
other three are known to spread various forms of encephalitis.West Virginia has
the fewest species of mosquitoes. There are 26 in the mountainous state, while
Texas has the most with 85. Florida is a close second with 80 identified species.
Mosquito is Spanish for “little fly.” The word reportedly originated in the
early 16th century. In Africa, New Zealand and Australia, mosquitoes are often
called “Mozzies”. Mosquitoes don't have teeth. The females “bite” with a long,
pointed mouthpart called a proboscis. They use the serrated proboscis to pierce
the skin and locate a capillary, then draw blood through one of two tubes.A mosquito can drink up to three times its weight in blood. Don't worry, though. It would take about 1.2 million bites to drain all the blood from your body.
Female mosquitoes can lay up to 300 eggs at a time. Usually, the eggs are
deposited in clusters – called rafts – on the surface of stagnant water, or
they are laid in areas that flood regularly. Eggs can hatch in as little as an
inch of standing water. Females will lay eggs up to three times before they
die.Mosquitoes spend their first 10 days in water. Water is necessary for the
eggs to hatch into larvae, called wigglers. Wigglers feed on organic matter in
stagnant water and breathe oxygen from the surface. They develop into pupae,
which do not feed and are partially encased in cocoons. Over several days, the
pupae change into adult mosquitoes.Mosquitoes hibernates. They are cold-blooded
and prefer temperatures over 80 degrees.
At
temperatures less than 50 degrees, they shut down for the winter. The adult
females of some species find holes where they wait for warmer weather, while
others lay their eggs in freezing water and die. The eggs keep until the
temperatures rise, and they can hatch.The average mosquito lifespan is less
than two months. Males have the shortest lives, usually 10 days or less, and
females can live about six to eight weeks, under ideal conditions. The females
lay eggs about every three days during that time. Females of species that
hibernate may live up to six months.
Mosquitoes mean nothing personal when they take your blood. Female
mosquitoes need protein for their eggs, and must take a blood meal in order to
reproduce. Since males don't bear the burden of producing young, they'll avoid
you completely and head for the flowers instead. And when not trying to produce
eggs, females are happy to stick to nectar, too.
