Title: 10 Most Dangerous Insects In The World
Post by: Aarif on October 25, 2010, 03:35:44 PM
There are more than a million species of known insects in the world. Some are quite harmless, while others are just designed to kill. Separating the good ones from the bad, this list states some unique facts about the ten most dangerous members of the insect world, especially for those who until now had underestimated these creatures because of their size:
1.  Human Bot Fly

Ok this is seriously horrifying. When these parasites are ready to reproduce, they look for a warm moist place on the human body to lay their eggs on. Sometimes they use a carrier like a mosquito to drop of the eggs. The heat of the body causes the eggs to hatch and for the next eight weeks the larvae burrows itself inside the human skin and feed off the human tissue. And here�s the most creepy part the larvae can grow anywhere in your body, including the brain. These facts about the Human Bot fly were enough to send chills down my spine and include this insect in my list.

2.  Kissing bugs
Found in South and Central America and the southern United States, these bugs are equipped with sucking tubes at the end of their mouths, with which they drain out the victim�s blood by painlessly piercing the lips, eyelids or ears. Their bites can transmit the Chaga�s disease into the prey�s body, which can result in chronic neurological disorders and serious damage to the heart and the digestive system. So if you�re in any of the above mentioned areas, make sure you close your windows before going to sleep, because believe me you don�t want to be kissed by these bugs!

3.  Fleas
Ever heard about the infamous Bubonic Plague that wiped out One-sixth of the world�s population in the 1340s? These blood sucking parasites were the ones behind it. They feed on warm-blooded vertebrates, and can infest an area rather quickly. The wound caused by a flea bite swells up in a pustule and can cause allergic reactions. Today fleas are no more than annoying house pests found mostly in our pets, but they were once responsible for killing 75 million which is why they are considered to be so dangerous.

4.  Siafu Ants
Moving about in colonies of twenty thousand individuals, these African ants will devour anything to the bone that comes their way. They are so strong that if you tear them in half after being bitten, their jaws will still be locked in your skin. Their queen holds the record for being the largest ant. Watch out for them if you ever happen to go on an African Safari.

5.  Wasps
Wasps normally don�t sting humans unless they consider them a threat, but if they do, they can cause some serious damages. A wasp�s sting can cause a person to go into anaphylactic shock and suffocate to death, or it could cause allergic reactions that can also be life threatening. So if there is a wasp family living in your attic, roof or garden, make sure you don�t get in their way and hire a professional to get rid of them.

6.  Fire Ants
Fire ants got their name from the burning sensation they cause when they sting their victim. The venom injected by their sting causes white pustules to show on the skin after 24 hours. Like all other ant species they also attack in masses but with a slightly different approach. The prey is first bitten by only one and then rest follow, therefore if you�re not quick to escape after the first bite you will surely be consumed by the whole swarm.

7.  Tsetse fly
Found only in Africa, these flies that are often mistaken for houseflies are actually the carriers of the sleeping sickness disease that affects the human nervous system. The disease starts off with the victim getting a flu, then falling in a coma due to the swelling of the brain and eventually ending in an inevitable death. Each year 250-300 lives are taken by this disease.

8.  Japanese Giant Hornet or Asian Hornet
These giant hornets can reach up to 3 inches in length and have the most painful sting than any other stinging insects. The venom injected from their stingers contains 8 different chemicals that not only cause tissue damage, but also leaves an odor that attracts more hornets to the victim. With a death toll of around 70 people every year, these fatal insects are a definite curse for the Japanese.

9.Killer Bees
Killer Bees or Africanized Honeybees are the result of a scientific experiment gone horribly wrong. The biologists behind this experiment were attempting to create a productive species of bees by interbreeding European honey bees with hardy African bees. But unfortunately this experiment failed and the bees, instead of being productive, developed an aggressive nature. These deadly get provoked very easily and attack in swarms, sometimes repeatedly stinging their victim throughout the day. The death toll which is in thousands is expected to climb up as these bees settle into new territories.

10. Anopheles Mosquito
Mosquitoes are not just your annoying household pests; they are also the carriers of the fatal disease Malaria which takes the lives of hundreds of millions of people every year. And that is why they rank first in our list for causing more deaths than any other insects combined.
