Sandfly species transmit the disease leishmaniasis, by acting as vectors for protozoan Leishmania species, and tsetse flies transmit protozoan trypansomes (Trypanosoma brucei gambiense and Trypansoma brucei rhodesiense) which cause African Trypanosomiasis (sleeping sickness). Ticks and lice form another large group of invertebrate vectors.

There are many insects (and other arthropods) that affect human health. These arthropods include Diptera, Hemiptera, Phthiraptera, and Siphonaptera. They can parasitize, bite, sting, cause allergic reactions, and/or vector disease to humans. It can be impossible to know the full impact that insects and other arthropods have on human health.
Insects are considered pests for a variety of reasons, including direct damage by feeding on crop plants in the field or by infesting stored products, indirect damage by spreading viral diseases of crop plants (especially by sucking insects such as leafhoppers), spreading disease among humans and livestock, and annoyance to humans.
The extent of the impact depends on characteristics of both the pest and host tree. [10] Pests differ in their means of attack and extent of damage. For example, defoliating insect (spongy moth) may weaken trees but not directly cause mortality, while boring insects (emerald ash borer) can often cause serious damage.
