Additional species were also later found infected as indicated below. disease transmission are Triatoma sanguisuga (Figure), with a range that stretches across the Southeast and into Maryland and Texas, and Triatoma gerstaekeri, found mainly in Texas and New Mexico. Triatoma sanguisuga is often called the bloodsucking conenose or the Mexican bed bug and in Trinidad is sometimes referred to as the “bloodsucker.” It has an oval shape with fourteen or more coloured horizontal lines which may be an orange-reddish or yellowish (Fig. Summary 4 Triatoma sanguisuga, also known as the Eastern Bloodsucking Conenose or the Mexican Bed Bug, is an insect of the Triatominae subfamily, known as kissing bugs.Like other species in this subfamily, T. sanguisuga is known to bite and feed off of humans at the mouth during sleep. Triatomine bugs live in a wide range of environmental settings, generally within close proximity to an animal the bug can feed on, called a blood host. Sequenced cytochrome b DNA segments obtained from triatomine digestive tract identified nine vertebrate hosts and one invertebrate host in four triatomine species (Triatoma gerstaeckeri, Triatoma indictiva, Triatoma protracta, and Triatoma sanguisuga). Humans accounted for the second most frequent blood source. Their legs are usually uniformly long and thin. The broad range of wild and domestic … This bite is painful and can cause adverse effects such as swelling, feelings of faintness, nausea, and … Figure 1. The distribution of Triatoma spp. Free Online Library: Triatoma sanguisuga blood meals and potential for chagas disease, Louisiana, USA. (DISPATCHES, Report) by "Emerging Infectious Diseases"; Health, general Chagas disease Risk factors Chagas' disease Disease transmission Research Medical research Medicine, Experimental Molecular diagnostic techniques Methods Triatominae Health aspects The range of T. gerstaeckeri includes New Mexico, most of Texas and northeast Mexico. Staff from the agriculture department preliminarily identified the insect as Triatoma sanguisuga, or the kissing bug. Triatoma sanguisuga Blood Meals and Potential for Chagas Disease, Louisiana, USA. Etienne Waleckx. Triatoma gerstaeckeri is an assassin bug in the genus Triatoma (kissing bugs). America, Triatoma sanguisuga is not the major invertebrate vector of Trypanosoma cruzi. T. gerstaeckeri goes through three stages during its paurometabolous life cycle: egg, nymphal instars and adult. The most important triatomine pecies in the United States for Chagas disease transmission are Triatoma sanguisuga, (click here for a photo) whose broad range extends across the southeast and reaches Maryland and Texas, and T. gerstaekeri, found in Texas and New Mexico (6). Credits: Alexander Wild, used with permission It is closely related to the so-called “kissing bug” or “masked bed bug hunter.’’ This species is tropical and sub-tropical in distribu- tion but its range extends … The insect was preliminarily identified as Triatoma sanguisuga (a “kissing bug”) by staff members from DDA. READ PAPER. in the Nearctic region is still not fully known, and their relevance as possible vectors of Trypanosoma cruzi to humans and animals is of growing concern. To evaluate human risk for Chagas disease, we molecularly identified blood meal sources and prevalence of Trypanosoma cruzi infection among 49 Triatoma sanguisuga kissing bugs in Louisiana, USA. to black and have a band around the edge of their body with stripes that can be orange or red. This paper. Triatoma sanguisuga is found in Florida, while Triatoma gerstaeckeri is not. Historically passive transport by humans expanded the geographic range of many vector species including two major vectors, Triatoma infestans and Rhodnius prolixus. Triatomines are blood-sucking insects that feed on animals and humans, and they have a predilection for biting the faces of humans (1). Among the 11 triatomine species in the United States, the most widely distributed and the only 2 found in Louisiana are Triatoma lecticularia and T. sanguisuga (5). Nymphs. For both species, Triatoma gerstaeckeri and T. sanguisuga, our SDMs predicted that there may be range shifts as result of climate change. Triatoma sanguisuga (Triatominae) (ranges from Arizona to Florida and up to Kansas and across to Maryland) Order: Coleoptera (beetles) Beetles are best characterized by the first set of wings, which have been hardened into structures termed "elytra." The western bloodsucking conenose, Triatoma protracta (Uhler) is an occasional pest in West Coast homes There the kissing bug of concern is Triatoma infestans, known as vinchuca or simply the bloodsucking conenose. However, the range of eggs laid per female was large (from 312 to 1166) indicating a need for more research in this area. Adult kissing bugs, or Triatoma sanguisuga, range from about 0.75 to 1.25 inches in length. For both species, Triatoma gerstaeckeri and T. sanguisuga, our SDMs predicted that there may be range shifts as result of climate change. The blood-sucking conenose, Triatoma sanguisuga (LeConte) is the most common species. 37 Full PDFs related to this paper. Also in the 1930s, T. cruzi infections were discovered in other species of bugs such as Triatoma uhleri (also known as Triatoma rubida) in Arizona (Kofoid and Whitaker, 1936) and Triatoma sanguisuga and Triatoma gerstaeckeri in Texas (Anonymous, 1938; Packchanian, 1939). The Centers for Disease Control and Prevention has issued a warning about Triatoma sanguisuga, a type of "kissing bug" that can pass along a parasitic disease. The inch-long triatomine bug is called the "kissing bug" because it has a habit of feeding on blood by biting around the lips and faces of … The most common species found in the south-central US are . Triatoma sanguisuga (LeConte), the eastern bloodsucking conenose, with a dime shown for scale. The most broadly distributed is Triatoma sanguisuga, across the entire eastern portion of the United States (Fig. are ¾ to 1 ¼ inches long. They range from light brown . 1 and Table 1) and is a highly infected species 25, 26 frequently found with human blood meals (Waleckx et al., Emerging Infectious Diseases, in press). Triatoma sanguisuga (Le Conte) is one of the larger cone nosed or assassin bugs of the family Reduviidae. Emerging Infectious Diseases, 2014. The bloodsucking conenose is usually brown or black in color and strikingly marked with red or orange. The most important triatomine species in the United States for Chagas disease transmission are Triatoma sanguisuga, whose broad range extends across the southeast and reaches Maryland and Texas, and T. gerstaekeri, found in Texas and New Mexico (6). Conenose bugs (Triatoma species) are insects that feed on the blood of various wild animals, particularly rodents. Other names for these insects are “kissing bugs” or “bloodsucking conenose bugs”. Humans accounted for the second most frequent blood source. For both species, Triatoma gerstaeckeri and T. sanguisuga, our SDMs predicted that there may be range shifts as result of climate change. Triatoma sanguisuga. Triatoma sanguisuga. Of the bugs that fed on humans, ≈40% were infected with T. cruzi, revealing transmission potential. Mammals are their most common hosts but they will occasionally feed on birds and reptiles. This kissing bug is known for the colorful striped reddish and orange patterns on its thorax. To evaluate human risk for Chagas disease, we molecularly identified blood meal sources and prevalence of Trypanosoma cruzi infection among 49 Triatoma sanguisuga kissing bugs in Louisiana, USA. Triatoma sanguisuga is the most common kissing bug found in the United States and can be found from the eastern portions of Texas and stretching through parts of the Midwest all the way to the Atlantic east coast. Methodology/Principal Findings:We forecast the future (2050) distributions in North America of Triatoma gerstaeckeri and T. sanguisuga, two of the most common triatomine species and important vectors of Trypanosoma cruzi in the southern United States. T. gerstaeckeri. Triatoma sanguisuga Triatomines are mostly active at night and feed on the blood of mammals (including humans), birds, and reptiles. In September 2016, we placed transmitters on two Triatoma sanguisuga (Leconte) (Hemiptera: Reduviidae) and one T. gerstaeckeri outside of a private residence in Brazos County in central Texas. Sequenced cytochrome b DNA segments obtained from triatomine digestive tract identified nine vertebrate hosts and one invertebrate host in four triatomine species (Triatoma gerstaeckeri, Triatoma indictiva, Triatoma protracta, and Triatoma sanguisuga). 1 and Table 1) and is a highly infected species 25,26 frequently found with human blood meals (Waleckx et al., Emerging Infectious Diseases, in press). and . Adult kissing bugs range … Download Full PDF Package. There is an active sylvan cycle in the United States and T. cruzi has been identified in more than 18 species, mainly opossums, Feeding habits of T. sanguisuga and T. gerstaeckeri differ from their Latin American counterparts. In many cases, the vector species were exclusively domestic in the extended range and … It is an important vector of Trypanosoma cruzi, the causative agent of Chagas disease. The most broadly distributed is Triatoma sanguisuga, across the entire eastern portion of the United States (Fig. Download PDF. A short summary of this paper. sources; 2) climate change that could extend the range of the vectors northward; and 3) introduction of parasites by migrants from disease-endemic countries (3–5). T. sanguisuga and T. gerstaeckeri are very cautious and neither will walk completely onto a host, reducing the chances of defecating on the host.
