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.
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]
The female Triatoma sanguisuga typically lays eggs four to six days after a blood meal. One female may lay hundreds of eggs in its lifetime. After the egg hatches, the immature bug takes a blood meal and molts eight times before reaching maturity. Triatoma sanguisuga feeds on blood from mammals such as raccoons, rats, dogs, cats, and humans. In ...

There are more than 2,000 species of tiny (0.04 to 0.15 inches), wingless, blood-sucking fleas that live on the body of the host they infest. Although fleas cannot fly, they have developed ...
A triatomine bug serves as the vector. While taking a blood meal, it ingests T. cruzi. In the triatomine bug (the principal species of which in terms of parasite transmission to humans being Triatoma infestans) the parasite goes into the epimastigote stage, making it possible to reproduce. After reproducing through binary fission, the ...
