Insects usually not attack unless provoked. Most bites and stings are defensive. Insects sting to protect their hives and nests.
A sting or bite injects venom composed of proteins and other substances that can trigger an allergic reaction in the victim. The bite also causes redness and swelling at the injection site.
Bees, wasps, hornets, yellow jackets and fire ants are Hymenoptera family. Bites or stings may cause serious reactions these species in persons who are allergic to them. The death of bee stings is 3-4 times higher than the death of snake bites (for details, see the stings of bees and wasps). Bees, wasps and ants differ in how they cause damage.
When the bee stings, it loses the entire injection apparatus (stinger) and actually in the process dies. WASP can cause multiple stings because it does not lose the injection device after it is injected.
Fire ants inject their venom, using their mandibles (biting parts of the jaw) and rotating their bodies. You can inject venom many times.
Instead of mosquitoes generally do not cause major illnesses, unless they transmit "vectors" or micro-organisms that actually live in these mosquitoes. For example, malaria is caused by an organism spends part of its life cycle of a particular species of mosquitoes. West Nile Virus is another disease spreading mosquitoes.
Other types of biting insects and diseases
Head lice can transmit epidemic relapsing fever caused by spirochetes.
Leishmaniasis, caused by the protozoan Leishmania, is carried by a mosquito.
Sleeping sickness in humans and a group of livestock diseases that are prevalent in Africa, known as nagana, is caused by protozoan trypanosomes transmitted by the bite of the tsetse fly.
In unsanitary conditions, the common housefly can have an occasional role in the proliferation of intestinal infections (such as typhoid fever and amoebic and bacillary dysentery) with contaminated food to humans.
Tularemia can be transmitted by an insect bite deer plague by fleas, and epidemic typhus rickettsiae by fleas.
Mosquitoes transmit several viral diseases (such as equine encephalitis, dengue and yellow fever in humans and other animals).
Ticks can transmit Lyme disease and other diseases through their bites or stings.
Other insects such as chiggers and mites typically cause self-limited local swelling and itching.
Severe bites of spiders not insects, may be the black widow or brown recluse.
