In the Southern Cone Initiative (WHO developmental stages of their life cycle in the 1992), the vector to control is Triatoma infestans ; intradomicile. in the Andean and Central American Countries Initiatives (WHO 1997, 1998), the vectors to Dipetologaster maxima has a wild life cycle (Lent eradicate is Rhodnius prolixus and to control T & Wygodzinsky 1979), but it has been observed in dimidiata . In the Mexico Initiative (Salazar et al the last years to be in a transition and adaptation 2001), no particular species is proposed, as there is process to the human housing. Of the eleven a large variety of vectors distributed along the visiting species, only nymphs in the last stages and whole country, from the smallest one, Belminus adults have been observed intradomiciliated; costaricensis in Veracruz, to the largest, however, they do not colonize the human dwelling Dipetalogaster maxima in Baja California Sur and their presence is not associated to any type of (Salazar et al 1988). All these species have been construction, they only enter the dwelling in search of related with Chagas disease (Cruz & Pickering food and, once obtained, they leave the dwelling. 2006).

We demonstrate that in R. prolixus following infection with epimastigotes of Trypanosoma cruzi clone Dm28c and, in comparison with uninfected control insects, the midgut contained (i) fewer bacteria, (ii) higher parasite numbers, and (iii) reduced nitrite and nitrate production and increased phenoloxidase and antibacterial activities. In addition, in insects pre-treated with antibiotic and then infected with Dm28c, there were also reduced bacteria numbers and a higher parasite load compared with insects solely infected with parasites. Furthermore, and in contrast to insects infected with Dm28c, infection with T. cruzi Y strain resulted in a slight decreased numbers of gut bacteria but not sufficient to mediate a successful parasite infection. We conclude that infection of R. prolixus with the T. cruzi Dm28c clone modifies the host gut immune responses to decrease the microbiota population and these changes are crucial for the parasite development in the insect gut.

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.

    Brown et al. Microbiome (2020) 8:146 https://doi.org/10.1186/s40168-020-00921-x RESEARCH Open Access Ontogeny, species identity, and environment dominate microbiome dynamics in wild populations of kissing bugs (Triatominae) Joel J. Brown1,2†, Sonia M. Rodríguez-Ruano1†, Anbu Poosakkannu1, Giampiero Batani1, Justin O. Schmidt3, Walter Roachell4, Jan Zima Jr1, Václav Hypša1 and Eva Nováková1,5* Abstract Background: Kissing bugs (Triatominae) are blood-feeding insects best known as the vectors of Trypanosoma cruzi, the causative agent of Chagas’ disease. Considering the high epidemiological relevance of these vectors, their biology and bacterial symbiosis remains surprisingly understudied. While previous investigations revealed generally low individual complexity but high among-individual variability of the triatomine microbiomes, any consistent microbiome determinants have not yet been identified across multiple Triatominae species. Methods: To obtain a more comprehensive view of triatomine microbiomes, we investigated the host-microbiome relationship of five Triatoma species sampled from white-throated woodrat (Neotoma albigula) nests in multiple locations across the USA. We applied optimised 16S rRNA gene metabarcoding with a novel 18S rRNA gene blocking primer to a set of 170 T. cruzi-negative individuals across all six instars. Results: Triatomine gut microbiome composition is strongly influenced by three principal factors: ontogeny, species identity, and the environment. The microbiomes are characterised by significant loss in bacterial diversity throughout ontogenetic development. First instars possess the highest bacterial diversity while adult microbiomes are routinely dominated by a single taxon. Primarily, the bacterial genus Dietzia dominates late-stage nymphs and adults of T. rubida, T. protracta, and T. lecticularia but is not present in the phylogenetically more distant T.
