Invertebrates spread bacterial, viral and protozoan pathogens by two main mechanisms. Either via their bite, as in the case of malaria spread by mosquitoes, or via their faeces, as in the case of Chagas' Disease spread by Triatoma bugs or epidemic typhus spread by human body lice. Many invertebrates are responsible for transmitting diseases.
The true bugs, Hemiptera, have piercing and sucking mouthparts and live by sucking sap from plants. These include aphids , whiteflies and scale insects . Apart from weakening the plant, they encourage the growth of sooty mould on the honeydew the insects produce, which cuts out the light and reduces photosynthesis, stunting the plant's growth.
Thankfully, while some insect bites can be itchy and uncomfortable, Kassouf says that most do not pose a serious risk to humans. In most cases, the discomfort and itchiness is worst in the first ...
Protozoan infections are responsible for diseases that affect many different types of organisms, including plants, animals, and some marine life. Many of the most prevalent and deadly human diseases are caused by a protozoan infection, including African sleeping sickness, amoebic dysentery, and malaria.
Some people suffer from “skeeter syndrome,” which causes the bites to grow into painful, swollen welts. Mosquitoes do carry a risk of certain diseases like West Nile and Zika, so monitor for ...

Chagas disease is caused by infection with the protozoan parasite T. cruzi, which is typically introduced into humans through the bite of triatomine bugs, also called "kissing bugs". [4] When the insect defecates at the bite site, motile T. cruzi forms called trypomastigotes enter the bloodstream and invade various host cells. [5]
