Chromosomal Divergence and Evolutionary Inferences in Rhodniini Based on the Chromosomal Location of Ribosomal Genes
376 Mem Inst Oswaldo Cruz, Rio de Janeiro, Vol. 108(3): 376-382, May 2013 Chromosomal divergence and evolutionary inferences in Rhodniini based on the chromosomal location of ribosomal genes Sebastián Pita1, Francisco Panzera1, Inés Ferrandis1, Cleber Galvão2, Andrés Gómez-Palacio3, Yanina Panzera1/+ 1Sección Genética Evolutiva, Facultad de Ciencias, Universidad de la República, Montevideo, Uruguay 2Laboratório Nacional e Internacional de Referência em Taxonomia de Triatomíneos, Instituto Oswaldo Cruz-Fiocruz, Rio de Janeiro, RJ, Brasil 3Grupo de Biología y Control de Enfermedades Infecciosas, Sede de Investigación Universitaria, Instituto de Biología, Universidad de Antioquia, Medellín, Colombia In this study, we used fluorescence in situ hybridisation to determine the chromosomal location of 45S rDNA clusters in 10 species of the tribe Rhodniini (Hemiptera: Reduviidae: Triatominae). The results showed striking inter and intraspecific variability, with the location of the rDNA clusters restricted to sex chromosomes with two patterns: either on one (X chromosome) or both sex chromosomes (X and Y chromosomes). This variation occurs within a genus that has an unchanging diploid chromosome number (2n = 22, including 20 autosomes and 2 sex chromo- somes) and a similar chromosome size and genomic DNA content, reflecting a genome dynamic not revealed by these chromosome traits. The rDNA variation in closely related species and the intraspecific polymorphism in Rhodnius ecuadoriensis suggested that the chromosomal position of rDNA clusters might be a useful marker to identify re- cently diverged species or populations. We discuss the ancestral position of ribosomal genes in the tribe Rhodniini and the possible mechanisms involved in the variation of the rDNA clusters, including the loss of rDNA loci on the Y chromosome, transposition and ectopic pairing. -
On Triatomines, Cockroaches and Haemolymphagy Under Laboratory Conditions: New Discoveries
Mem Inst Oswaldo Cruz, Rio de Janeiro, Vol. 111(10): 605-613, October 2016 605 On triatomines, cockroaches and haemolymphagy under laboratory conditions: new discoveries Pamela Durán1, Edda Siñani2, Stéphanie Depickère2,3/+ 1Universidad Mayor de San Andrés, Instituto de Investigación en Salud y Desarrollo, Cátedra de Parasitología, La Paz, Bolivia 2Instituto Nacional de Laboratorios de Salud, Laboratorio de Entomología Médica, La Paz, Bolivia 3Institut de Recherche pour le Développement, Embajada Francia, La Paz, Plurinational State of Bolivia For a long time, haematophagy was considered an obligate condition for triatomines (Hemiptera: Reduviidae) to complete their life cycle. Today, the ability to use haemolymphagy is suggested to represent an important survival strategy for some species, especially those in genus Belminus. As Eratyrus mucronatus and Triatoma boliviana are found with cockroaches in the Blaberinae subfamily in Bolivia, their developmental cycle from egg to adult under a “cockroach diet” was studied. The results suggested that having only cockroach haemolymph as a food source com- promised development cycle completion in both species. Compared to a “mouse diet”, the cockroach diet increased: (i) the mortality at each nymphal instar; (ii) the number of feedings needed to molt; (iii) the volume of the maximum food intake; and (iv) the time needed to molt. In conclusion, haemolymph could effectively support survival in the field in both species. Nevertheless, under laboratory conditions, the use of haemolymphagy as a survival strategy in the first developmental stages of these species was not supported, as their mortality was very high. Finally, when Triatoma infestans, Rhodnius stali and Panstrongylus rufotuberculatus species were reared on a cockroach diet under similar conditions, all died rather than feeding on cockroaches. -

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).

Control of insect vectors is often the best, and some- times the only, way to protect the population from these destructive diseases. Vector control is a moving target with globalization and demographic changes causing changes in infection patterns (e.g., rapid spread, urbanization, appearance in nonen- demic countries); and the current unprecedented degradation of the global environment is affecting rates and patterns of vector-borne disease in still largely unknown ways. 15.1.2 Contributions of Genetic Studies of Vectors to Understanding Disease Epidemiology and Effective Disease Control Methods Studies of vector genetics have much to contribute to understanding vector-borne disease epidemiology and to designing successful control methods. Geneticists have performed phylogenetic analyses of major species; have identified new spe- cies, subspecies, cryptic species, and introduced vectors; and have determined which taxa are epidemiologically important. Cytogeneticists have shown that the evolution of chromosome structure is important in insect vector speciation. -

Triatoma Melanica? Rita De Cássia Moreira De Souza1*†, Gabriel H Campolina-Silva1†, Claudia Mendonça Bezerra2, Liléia Diotaiuti1 and David E Gorla3
Souza et al. Parasites & Vectors (2015) 8:361 DOI 10.1186/s13071-015-0973-4 RESEARCH Open Access Does Triatoma brasiliensis occupy the same environmental niche space as Triatoma melanica? Rita de Cássia Moreira de Souza1*†, Gabriel H Campolina-Silva1†, Claudia Mendonça Bezerra2, Liléia Diotaiuti1 and David E Gorla3 Abstract Background: Triatomines (Hemiptera, Reduviidae) are vectors of Trypanosoma cruzi, the causative agent of Chagas disease, one of the most important vector-borne diseases in Latin America. This study compares the environmental niche spaces of Triatoma brasiliensis and Triatoma melanica using ecological niche modelling and reports findings on DNA barcoding and wing geometric morphometrics as tools for the identification of these species. Methods: We compared the geographic distribution of the species using generalized linear models fitted to elevation and current data on land surface temperature, vegetation cover and rainfall recorded by earth observation satellites for northeastern Brazil. Additionally, we evaluated nucleotide sequence data from the barcode region of the mitochondrial cytochrome c oxidase subunit I (CO1) and wing geometric morphometrics as taxonomic identification tools for T. brasiliensis and T. melanica. Results: The ecological niche models show that the environmental spaces currently occupied by T. brasiliensis and T. melanica are similar although not equivalent, and associated with the caatinga ecosystem. The CO1 sequence analyses based on pair wise genetic distance matrix calculated using Kimura 2-Parameter (K2P) evolutionary model, clearly separate the two species, supporting the barcoding gap. Wing size and shape analyses based on seven landmarks of 72 field specimens confirmed consistent differences between T. brasiliensis and T. melanica. Conclusion: Our results suggest that the separation of the two species should be attributed to a factor that does not include the current environmental conditions. -

Several species can transmit the protozoan parasite Trypanosoma cruzi, the causative agent of Chagas disease, significantly impacting public health in Latin American countries. The Triatominae can be classified into five tribes, of which the Rhodniini is very important because of its large vector capacity and wide geographical distribution. The Rhodniini tribe comprises 23 (without R. taquarussuensis) species and although several studies have addressed their taxonomy using morphological, morphometric, cytogenetic, and molecular techniques, their evolutionary relationships remain unclear, resulting in inconsistencies at the classification level. Conflicting hypotheses have been proposed regarding the origin, diversification, and identification of these species in Latin America, muddying our understanding of their dispersion and current geographic distribution. -

Monteiro3,4*, Márcio G. Pavan5, James S. Patterson2, M. Dolores Bargues6, M. Ángeles Zuriaga6, Marcelo Aguilar7,8, Charles B. Beard4, Santiago Mas‑Coma6 and Michael A. Miles2 Abstract Background: Triatomine bugs, the vectors of Chagas disease, associate with vertebrate hosts in highly diverse ecotopes. It has been proposed that occupation of new microhabitats may trigger selection for distinct phenotypic variants in these blood‑sucking bugs. Although understanding phenotypic variation is key to the study of adaptive evolution and central to phenotype‑based taxonomy, the drivers of phenotypic change and diversity in triatomines remain poorly understood. Methods/results: We combined a detailed phenotypic appraisal (including morphology and morphometrics) with mitochondrial cytb and nuclear ITS2 DNA sequence analyses to study Rhodnius ecuadoriensis populations from across the species’ range. We found three major, naked‑eye phenotypic variants. Southern‑Andean bugs primarily from vertebrate‑nest microhabitats (Ecuador/Peru) are typical, light‑colored, small bugs with short heads/wings. Northern‑ Andean bugs from wet‑forest palms (Ecuador) are dark, large bugs with long heads/wings. Finally, northern‑lowland bugs primarily from dry‑forest palms (Ecuador) are light‑colored and medium‑sized. Wing and (size‑free) head shapes are similar across Ecuadorian populations, regardless of habitat or phenotype, but distinct in Peruvian bugs. Bayesian phylogenetic and multispecies‑coalescent DNA sequence analyses strongly suggest that Ecuadorian and Peruvian populations are two independently evolving lineages, with little within‑lineage phylogeographic structuring or diferentiation. -
