Top 10 Extremely Dangerous Insects in the world
10. Hemiptera – kissing bugs
The
bugs from hemiptera classification have distinct ‘sucking’ mouth parts
and resemble tubes. Majority of them feed on plant sap in one or the
other form. But few of them are exception and feed on the blood of
larger animals. The bugs are known to transmit Chagas Disease. The
symptoms change over the course of infection. In the early acute stage
the symptom are mild and displays no more than local swelling at
infection site. The disease stays for over twenty years and as the
disease progresses more serious symptoms appear such as heart disease.
The symptom also includes malfunction of intestine. . If the disease is
not treated, the chronic disease could be fatal. The present drug
treatment is unsatisfactory since they are highly toxic and ineffective,
especially in the chronic stage.
9. Giant Japanese or Asian Hornet
This
hornet can grow in length up to 3 inches. It is well know that only 20
to 30 of them can decimate an entire hive of honeybees. The sting can be
lethal, not only in terms of allergic reactions, but also because they
carry many toxins. The sting of this hornet has got highest
concentration of Acetylcholine, a pain-causing chemical compared to the
sting of any other insect. Enzyme present in their venom can dissolve
human tissues. The sting contains at least eight distinct chemicals;
interestingly their venom attracts others of its kinds to the victim.
These hornets can sting repeatedly.
8. Siafu (African Ants)Dorylus
Everyone
knows that ants are industrious, yet these Siafu ants are special.
Their single colony of 20 million ants can easily ravage African
countryside, literally destroying anything that comes their way. When
there is a food shortage, the whole colony marches out, be whatever
comes their way, to acquire food. These ants can easily be avoided, yet
each year 20 to 50 people die. Most of the times very young and elderly
find themselves as the victims of asphyxiation. They are also behind
damage worth thousands of dollars of food each year.
7. Wasps
They
are mostly not one of the extremely dangerous insects. These wasps in
their yellow jackets with hornets are relatively social and generally
terrestrial. They will generally their own parasite or pest that they
prey upon exclusively. They do not intensively lookout of humans to
sting. However if their territories are being threatened they will not
refrain themselves from stinging. Their stings are oft-allergic and
cause most damage. It results in anaphylactic shock and the victim may
even die as a result of a single wasp sting.
6. Locusts
You
must be thing what a locust is doing in this list. They are not by any
chance known for killing humans at least directly. Yet still their
strength lies in their number that that is the threat they pose each
year. Locust can strip bare earth in thousands of acres of crop land
every year in a very short time since each swarm consist of several
thousands of insects and they can contribute to death by starvation.
5. Fire Ants
At
the 5th position of extremely dangerous insects we have Fire ants that
build large mounds and feed on plant leaves. They occasionally feed on
crickets and small insects. But is they are bothered, they don’t
hesitate to sting. The sting of fire ants is venomous prick and it feels
like burning with fire. This is how they have got their name as Fire
Ants. Few small stings can easily and quickly treated and cured. However
when the swarm of ants attacks, it could be the beginning of the real
trouble. Each year 150 deaths are reported and millions of dollars are
lost due to crop damage making these ants fearsome.
4. TseTse
This
insect is the carrier of the deadly sleeping sickness. It feeds on the
blood of vertebrates and this is how it spreads trypanosomiases disease
in humans. The death toll in Africa is alarming because of their biting.
Every year 250 to 300 thousands victims are reported each year.
3. Honey Bees
Their
numbers have increased over the years. They actually pose no threat to
humans since they have no intent to do so. More so ever even if they
sting, they die after the deed is done. Many people world over are
allergic towards their sting. And many of them experience death due to
anaphylactic shock. However unlike standard bees, these bees attack
victims in swarm with slightest provocation. Each the death toll is
reported in thousands.
2. Fleas
Fleas
are dangerous are directly responsible for spreading Plague that they
receive from their host rats. Hence their bits are not one of those
annoying little bits, but indeed are serious. Fleas contribute to the
spread of Bubonic Plague. They receive it from their host rats and pass
it over to humans carrying Yersinia Pestsis. Fleas feed on the blood of
warm-blooded vertebrates and can easily infest animal and humans. If
bitten the wound swells and leads to allergic reaction.
1. Anopheles Mosquito
At
the first position of extremely dangerous insects we have Anopheles
Mosquitoes which are one of those a terrible irritant and feed on blood.
The mosquitoes lay their eggs in stagnant and unattended water sources.
Millions of mosquitoes can hatch from just a single source. However the
real threat the mosquitoes pose are the blood-borne diseases that they
carry. Most dangerous notorious of all is the Malaria. Every year
hundreds and millions of people die because of malaria. In fact the
death caused by malaria will outnumber all of the death caused by
putting all of the insects together.
