Although, Triatoma and Rhodnius are the vector genera most studied, other triatomines such as Panstrongylus can also contribute to T. cruzi transmission creating new epidemiological scenarios that involve domiciliation. Panstrongylus has at least twelve reported species but there is limited information about their intraspecific diversity and patterns of diversification. Here, we began to fill this gap, studying intraspecific variation in Colombian populations of P. geniculatus. Methodology/Principal finding We examined the pattern of diversification as well as the genetic diversity of P. geniculatus in Colombia using mitochondrial and ribosomal data. We calculated genetic summary statistics within and among P. geniculatus populations. We also estimated genetic divergence of this species from other species in the genus (P.

JURBERG & C. GALVÃO Abstract: The members of the subfamily Triatominae (Heteroptera, Reduviidae) are vectors of Try- panosoma cruzi (CHAGAS 1909), the causative agent of Chagas disease or American trypanosomiasis. As important vectors, triatomine bugs have attracted ongoing attention, and, thus, various aspects of their systematics, biology, ecology, biogeography, and evolution have been studied for decades. In the present paper the authors summarize the current knowledge on the biology, ecology, and systematics of these vectors and discuss the implications for human health. Key words: Chagas disease, Hemiptera, Triatominae, Trypanosoma cruzi, vectors. Historical background (DARWIN 1871; LENT & WYGODZINSKY 1979). The first triatomine bug species was de- scribed scientifically by Carl DE GEER American trypanosomiasis or Chagas (1773), (Fig. 1), but according to LENT & disease was discovered in 1909 under curi- WYGODZINSKY (1979), the first report on as- ous circumstances. In 1907, the Brazilian pects and habits dated back to 1590, by physician Carlos Ribeiro Justiniano das Reginaldo de Lizárraga.

It is based on field collections carried out between 1993-2008, museum collections and a literature review. Fourteen species, representing four tribes and six genera, are now known in this country and are illustrated (habitus). Three species are recorded from French Guiana for the first time: Cavernicola pilosa, Microtriatoma trinidadensis and Rhodnius paraensis. The two most common and widely distributed species are Panstrongylus geniculatus and Rhodnius pictipes. The presence of two species (Panstrongylus megistus and Triatoma maculata) could be fortuitous and requires confirmation. Also, the presence of Rhodnius prolixus is doubtful; while it was previously recorded in French Guiana, it was probably mistaken for R. robustus. A key for French Guiana’s triatomine species is provided.

    Comprehensive Summaries of Uppsala Dissertations from the Faculty of Science and Technology 895 Ecology and Control of Triatomine (Hemiptera:Reduviidae) Vectors of Chagas Disease in Guatemala, Central America BY MARIA CARLOTA MONROY ACTA UNIVERSITATIS UPSALIENSIS UPPSALA 2003 Dissertation presented at Uppsala University to be publicly examined in Ekman salen, Evolutionary Biology Centre Norbyvägen 14, Uppsala, Tuesday, November 25, 2003 at 13:00 for the degree of Doctor of Philosophy. The examination will be conducted in English. ABSTRACT Monroy, M. C. 2003. Ecology and Control of Triatomine (Hemiptera: Reduviidae) Vectors of Chagas Disease in Guatemala, Central America. Acta Universitatis Upsaliensis. Comprehensive summaries of Uppsala Dissertations from the Faculty of Science and Technology 895. 22 pp. Uppsala. ISBN 91-554-5756-8 This thesis analyses several ecological factors affecting the control of triatomines in Guatemala. There are three synanthropic triatomines in Guatemala, i. e., Rhodnius prolixus, Triatoma dimidiata and T. nitida. Their distribution is mainly at an altitude between 800 and 1500 m. a. s. l. R. prolixus and T. nitida have localized but scattered distributions while T. dimidiata is present in 21 of the 22 departments in the country. Several investigations have shown that R. prolixus could be relatively easily eradicated while T. dimidiata may be more difficult to control, since it is present in domestic, peridomestic and sylvatic environments showing high diversity and a variety of epidemiological characteristics. Based on the incidence of Trypanosoma cruzi infection in humans in the distributional areas of the triatomines, R. prolixus appears to be a more competent vector than T. dimidiata. This is despite the fact that these vectors have similar infection rates.

  • Human Cultural Practices Illuminate the Blood Meal Sources of Cave Dwelling Chagas Vectors (Triatoma Dimidiata)In Guatemala and Belize
    Hunting, Swimming, and Worshiping: Human Cultural Practices Illuminate the Blood Meal Sources of Cave Dwelling Chagas Vectors (Triatoma dimidiata)in Guatemala and Belize Lori Stevens1*, M. Carlota Monroy2, Antonieta Guadalupe Rodas2, Patricia L. Dorn3 1 Department of Biology, College of Arts and Sciences, University of Vermont, Burlington, Vermont, United States of America, 2 Escuela de Biologia, Universidad de San Carlos de Guatemala, Ciudad de Guatemala, Guatemala, 3 Department of Biological Sciences, Loyola University New Orleans, New Orleans, Louisiana, United States of America Abstract Background: Triatoma dimidiata, currently the major Central American vector of Trypanosoma cruzi, the parasite that causes Chagas disease, inhabits caves throughout the region. This research investigates the possibility that cave dwelling T. dimidiata might transmit the parasite to humans and links the blood meal sources of cave vectors to cultural practices that differ among locations. Methodology/Principal Findings: We determined the blood meal sources of twenty-four T. dimidiata collected from two locations in Guatemala and one in Belize where human interactions with the caves differ. Blood meal sources were determined by cloning and sequencing PCR products amplified from DNA extracted from the vector abdomen using primers specific for the vertebrate 12S mitochondrial gene. The blood meal sources were inferred by $99% identity with published sequences. We found 70% of cave-collected T. dimidiata positive for human DNA. The vectors had fed on 10 additional vertebrates with a variety of relationships to humans, including companion animal (dog), food animals (pig, sheep/goat), wild animals (duck, two bat, two opossum species) and commensal animals (mouse, rat). Vectors from all locations fed on humans and commensal animals.

Herein, we provide a comprehensive description of domestic and intrusive tria- Monte ecoregion tomines to evaluate the risk of reinfestation of rural dwellings. Triatoma infestans, T. patagonica, T. garciabesi and Argentina T. eratyrusiformis were collected by active searches or light traps. None were infected with T. cruzi. One T. infestans male was collected at 1.3 km from the nearest infested house. The finding of intrusive and domestic triatomines in sylvatic foci emphasizes the need of implementing an effective vector surveillance system.

    Chagas Disease Vectors Identification using Data Mining and Deep Learning Techniques Presented in Partial Fulfillment of the Requirements for the Degree of Master of Science with a Major in Electrical and Computer Engineering in the Department of Electrical and Computer Engineering and Computer Science University of Detroit Mercy by Zeinab Ghasemi Major Professor Dr.Shadi Bani Taan,Ph.D. Committee Dr.Mohammad Fanaei,Ph.D. Dr.Mina Maleki,Ph.D. August 2020 ii Abstract Chagas Disease (CD) is a vector–borne infectious disease transmitted from animals to humans and reversely. It is caused by the parasite Trypanosoma cruzi (abbv. as T. cruzi). It is forcing an enormous social burden on public health and counts as one of the most major threats to human health. Based on WHO statistical analysis in 2019, CD affects about 7 million people and is responsible for nearly 50,000 annual mortalities around the world. Also an average of 80 million people are living in risky areas for infection in different parts of the world. The disease has two phases of acute and chronic. Diagnosing of CD can be performed at both acute and chronic phases. It invloves analyzing clinical, epidemi- ological, and laboratory data. Since controlling and treating CD is easier in the early stages, detecting it in the acute phase plays an essential role in overcoming and controlling it. There are many clinical trials dedicated to this problem, but progress in compu- tational research (automatic identification) has been limited. Therefore, this work presents four automated CD vector identification approaches that classify several different vectors of kissing bugs with acceptable accuracy rates.
