Insect Bites Definition
Stings and bites from insects are common. They often result in redness and swelling in the injured area. Sometimes a sting or bite can cause a life-threatening allergic reaction or transmit pathogens (viruses, bacteria or parasites, for example) to humans.
Arthropods are insects that live primarily on land and have six legs. They dominate the present-day land fauna. They represent about three-fourths of known animal life. In fact, the actual number of living species is not known and is estimated to be over 10 million.
The orders that contain the greatest numbers of species are:
However, the majority of people lump insects, arthropods, and anything small that bites or stings as a "bug" or an insect. The goal of this article is to provide an overview of biting and stinging insects or bugs without making strict scientific definitions of insects or bugs. The article covers the predominant biting and stinging bugs seen or imported to the US recently, but does not cover every possible stinging or biting bug or insect worldwide.
Insect Bites causes
Most insects do not usually attack humans unless they are provoked. Many bites and stings are defensive. Insects sting to protect their hives or nests or when incidentally touched or disturbed (so hives and nests should not be disturbed or approached).
A sting or bite injects venom composed of proteins and other substances that may trigger an allergic reaction in the victim. The sting also causes redness and swelling at the site of the sting.
Bees, wasps, hornets, yellow jackets, and fire ants are members of the Hymenoptera family. Bites or stings from these species may cause serious reactions in people who are allergic to them. Death from bee stings is 3 to 4 times more common than death from snake bites. Bees, wasps, and fire ants differ in how they inflict injury.
Other types of insects or bugs that bite for a blood meal and diseases that are possibly transmitted are as follows:
Other insects and bugs can transmit diseases by simply transferring pathogens like Salmonella spp by contact. For example, in unsanitary conditions, the common housefly can play an incidental role in the spread of human intestinal infections (such as typhoid, bacillary and amebic dysentery) by contamination of human food as it lands and "walks" over foods after previously "walking" on contaminated items like feces.
