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]

These are species according to reliable sources. While most species are found in the New World, a few are known from the Old World. [2] [3] [4] [5] NOTE:The designation (Tc) signifies that the species is associated with Trypanosoma cruzi .

<span class="mw-page-title-main">Triatominae</span> Subfamily of true bugs

The members of the Triatominae, a subfamily of the Reduviidae, are also known as conenose bugs, kissing bugs, or vampire bugs. Other local names for them used in the Americas include barbeiros, vinchucas, pitos, chipos and chinches. Most of the 130 or more species of this subfamily feed on vertebrate blood; a very few species feed on invertebrates. They are mainly found and widespread in the Americas, with a few species present in Asia and Africa. These bugs usually share shelter with nesting vertebrates, from which they suck blood. In areas where Chagas disease occurs, all triatomine species are potential vectors of the Chagas disease parasite Trypanosoma cruzi, but only those species that are well adapted to living with humans are considered important vectors. Also, proteins released from their bites have been known to induce anaphylaxis in sensitive and sensitized individuals.

The Genus Panstrongylus Berg, 1879 belongs to the subfamily Triatominae. It is found in South America.

<i>Rhodnius</i> Genus of true bugs

Rhodnius is a genus of assassin bugs in the subfamily Triatominae, and is an important vector in the spread of Chagas disease. The Rhodnius species were important models for Sir Vincent Wigglesworth's studies of insect physiology, specifically growth and development.

Parabelminus is a genus of bugs in the subfamily Triatominae. The species of this genus could be found in Brazil, specially in Rio de Janeiro and Bahia. It is a vector of Chagas disease.

<i>Panstrongylus geniculatus</i> Species of true bug

Panstrogylus geniculatus is a blood-sucking sylvatic insect noted as a putative vector of minor importance in the transmission of Trypanosoma cruzi to humans; this is a parasite, which causes Chagas disease. The insect is described as sylvatic; subsisting primarily in humid forests, and is also known to inhabit vertebrate nesting places such as those of the armadillo, and is also involved in enzootic transmission of T. cruzi to those species. It has wide distribution throughout 16 Latin American countries.

<i>Triatoma nigromaculata</i> Species of true bug

Triatoma nigromaculata is a sylvatic species of insect usually found in hollow trees, in vertebrate nests on trees and occasionally in human dwellings. It usually lives in relatively humid forests at high altitudes on mountain regions and foot hills. As all members of the subfamily Triatominae, T. nigromaculata is a blood-sucking bug and a potential vector of Chagas disease. This species is distributed mainly in Venezuela, but some specimens have also been found in Perú and Colombia (Cauca).

Triatoma melanica is a hematophagous insect, a Chagas disease vector, included in the Triatominae group. It occurs in the north of Minas Gerais state, Brazil, and is found almost exclusively in silvatic environment. However, sporadically it may also invade houses. T. melanica was originally described as Triatoma brasiliensis melanica Neiva & Lent, 1941. Recently, it was redescribed with a new specific status, due to its distinct morphology, genetics, and biogeographic characteristics.

<i>Triatoma brasiliensis</i> Species of true bug

Triatoma brasiliensis is now considered the most important Chagas disease vector in the semiarid areas of northeastern Brazil. T. brasiliensis occurs in 12 Brazilian states, including Maranhão, Piauí, Ceará, Rio Grande do Norte, and Paraíba.

Triatoma juazeirensis is an assassin bug, a Chagas disease vector which occurs in the State of Bahia, Brazil. It is found in natural and artificial environments infesting mainly the peridomiciliary areas but it may also colonize the intradomicile. T. juazeirensis can be distinguished from the other members of the brasiliensis complex by its entire dark pronotum and legs.

<i>Triatoma rubrovaria</i> Species of true bug

Triatoma rubrovaria is an insect which is ubiquitous in Uruguay, in neighboring parts of northeastern Argentina, and in the southern states of Paraná and Rio Grande do Sul in Brazil. This species of triatomine is found mainly among exfoliate rocks known as pedregales. It was earlier reported as T. (triatoma) rubrovaria, a sylvatic species inhabiting rock piles, rarely found in human dwellings. This species may be a highly competent vector of Trypanosoma cruzi, the causative agent of Chagas disease. In Rio Grande do Sul, data from the Chagas disease Control Program have indicated an increasing of domiciliary and peridomiciliary invasion of T. rubrovaria, where it has become the most frequently triatomine species captured in that State since the control of T. infestans.

Triatoma platensis is a species of assassin bug in the family Reduviidae. It is found in South America.

<i>Triatoma gerstaeckeri</i> Species of true bug

Triatoma gerstaeckeri is an assassin bug in the genus Triatoma. It is an important vector of Trypanosoma cruzi, the causative agent of Chagas disease. The range of T. gerstaeckeri is from the south-western United States to north-eastern Mexico. T. gerstaeckeri goes through three stages during its paurometabolous life cycle: egg, nymphal instars and adult.

<i>Triatoma lecticularia</i> Species of true bug

Triatoma lecticularia is a species of kissing bug in the family Reduviidae. It is found in Central America and North America.

Triatoma recurva is a species of kissing bug in the family Reduviidae. It is found in Central America and North America. Like all of the kissing bugs in the genus Triatoma, it is an obligate blood feeder that primarily targets vertebrates. However, individuals can consume the hemolymph of arthropods, and can develop to maturity on a diet consisting entirely of cockroaches.

Triatoma rubida is a species of kissing bug in the family Reduviidae. It is found in Central America and North America.

Triatoma neotomae is a species of kissing bug in the family Reduviidae. It is found in Central America and North America.

<i>Linshcosteus</i> Genus of true bugs

Linshcosteus is a genus of assassin bugs in the subfamily Triatominae. It is the only genus of Triatomines restricted to the Old World within the mostly Neotropical subfamily Triatominae and consists of six species restricted to peninsular India. Within the Triatominae, the genus is differentiated by the lack of a prosternal stridulatory furrow and a short rostrum that does not reach the prosternum. Adults feed on vertebrate blood.

<i>Triatoma sordida</i> Species of true bug

Triatoma sordida is an assassin bug within the genus Triatoma. This species consists of three subspecies. Also referred to as kissing bugs, T.sordida are most well known for their role as a secondary vector of Chagas Disease. Inhabiting warm, dry climates, T.sordida are widely distributed throughout South America, occupying houses, farming structures, and wild habitats. Pest control is currently focused on insecticide application. However, biological controls utilizing fungi appear promising.

Could I be allergic to the bite of a triatomine bug? -- Yes. The saliva of certain types of triatomines can cause an allergic reaction in some people. An allergic reaction may be characterized by severe redness, itching, swelling, welts, hives, or, rarely, anaphylactic shock (severe allergic reaction). ... It is important to note that not all triatomines are infected with the parasite even though they may cause an allergic reaction.
