Triatoma is a genus of assassin bug in the subfamily Triatominae (kissing bugs). The members of Triatoma (like all members of Triatominae) are blood-sucking insects that can transmit serious diseases, such as Chagas disease. Their saliva may also trigger allergic reactions in sensitive individuals, up to and including severe anaphylactic shock. [1]
There are currently around 28,000 new cases of Chagas disease annually, a significant decrease from 700,000 new cases diagnosed in 1990. [6] Like other species of kissing bugs, Triatoma sanguisuga is known to bite humans in the face, usually around the mouth or eyes, and feed off the blood. This normally occurs during sleep.
Triatoma infestans, commonly called winchuka [1] or vinchuca [2] in Argentina, Bolivia, Uruguay and Chile, barbeiro in Brazil, chipo in Venezuela and also known as "kissing bug" or "barber bug" in English, is a blood-sucking bug (like virtually all the members of its subfamily Triatominae) and the most important vector of Trypanosoma cruzi which can lead to Chagas disease.
Chiggers attach to the host, pierce the skin, inject enzymes into the bite wound that digest cellular contents, [23] and then suck up the digested tissue through a tube formed by hardened skin cells called a stylostome. [24] They do not burrow into the skin or suck blood, as is commonly assumed.
There are many reasons dogs eat grass, and most of them are relatively harmless. So is it OK for dogs to eat grass? Here's what owners should know.
Most of the parasitic mites do not feed directly on blood, but the dermanyssid mites and larval trombiculid mites directly suck up capillary blood as their exclusive food. The tube through which food is ingested and saliva excreted during feeding is formed in most mites by apposing the sheath that contains the chelicerae against the hypostome.
"Only fertilized female mosquitoes will suck blood, because they need proteins to make their eggs develop. Males and unfertilized females will eat some nectar from plants. And some males do not ...
Vernacular terms to describe diseases caused by mites include scab, mange, and scabies. Mites and ticks have substantially different biology from, and are classed separately from, insects (the class Insecta). Mites of domestic animals cause important types of skin disease, and some mites infest other organs. Diagnosis of mite infestations can ...
