“…For example, some juvenile instars of E. mucronatus can feed on hemolymphs of large arachnids (Amblypygi) that dwell in trunks and hollow trees (Gaunt and Miles 2000). There are also reports of P. geniculatus feeding on moths during night capture (Garrouste 2009), and Belminus herreri (Lent & Wygodzinsky) and Belminus ferroae (Sandoval, Pabón, Jurberg & Galvão) have been detected feeding on members of the Blattidae family in Colombian dwellings (Sandoval et al 2004(Sandoval et al , 2010. On the other hand, in laboratory conditions, the R. prolixus nymphs practice cannibalism and cleptohematophagy (Piñero et al 1988).…”

All members of Triatominae subfamily (Heteroptera: Reduviidae), potential vectors of Trypanosoma cruzi, etiologic agent of the Chagas disease, feed on blood. Through evolution, these bugs have fixed special morphological, physiological, and behavioral aptations (adaptations and exaptations) adequate to feed on blood. Phylogeny suggests that triatomines evolved from predator reduvids which in turn descended from phytophagous hemipterans. Some pleisiomorphic traits developed by the reduvid ancestors of the triatomines facilitated and modeled hematophagy in these insects. Among them, mouthparts, saliva composition, enzymes, and digestive symbionts are the most noticeable. However, the decisive step that allowed the shift from predation to hematophagy was a change of behavior. The association of a predator reduvid with nesting vertebrate (≈110 to 32 Ma) permitted the shift from an arthropod prey to a vertebrate host. In this work, we review the phylogeny and dispersion of triatomines and the current controversy over the monophyly or polyphyly of this group. We also discuss how these insects were able to overcome, and even have taken advantage of, diverse ancestral and physical barriers to adapt to sucking blood of nidicolous vertebrates. We provide a Spanish version of this work.

“…Cavernicola pilosa Barber appears to only feed on bats ( Usinger, 1944 ; Oliveira et al, 2008 ), while Triatoma delpontei Romaña and Abalos and Psammolestes Bergroth species are usually found in association with various birds ( Usinger, 1944 ; Salvatella et al, 1992 ). In addition, there are reports of some kissing bug species feeding on other arthropods ( Garrouste, 2009 ; Sandoval et al, 2010 ; Kjos et al, 2013 ), feeding on other engorged kissing bug individuals ( Sandoval et al, 2004 ) and even facultative nectar feeding ( Díaz-Albiter et al, 2016 ). The extent of these behaviors in a natural environment and for the great majority of kissing bug species is unknown.…”

BackgroundThe 152 extant species of kissing bug include important vectors of the debilitating, chronic, and often fatal Chagas disease, which affects several million people mainly in Central and South America. An understanding of the natural hosts of this speciose group of blood-feeding insects has and will continue to aid ongoing efforts to impede the spread of Chagas disease. However, information on kissing bug biology is piecemeal and scattered, developed using methods with varying levels of accuracy over more than 100 years. Existing host records are heavily biased towards well-studied primary vector species and are derived from primarily three different types of observations, associational, immunological or DNA-based, with varying reliability.MethodsWe gather a comprehensive and unparalleled number of sources reporting host associations via rigorous targeted searches of publication databases to review all known natural, or sylvatic, host records including information on how each record was collected. We integrate this information with novel host records obtained via attempted amplification and sequencing of a ∼160 base pair (bp) region of the vertebrate 12S mitochondrial gene from the gastrointestinal tract of 64 archival specimens of Triatominae representing 19 species collected primarily in sylvatic habitats throughout the southern United States and Central and South America during the past 10 years. We show the utility of this method for uncovering novel and under-studied groups of Triatominae hosts, as well as detecting the presence of the Chagas disease pathogen via Polymerase Chain Reaction (PCR) of a ∼400 bp sequence of the trypanosome 18S gene.ResultsNew host associations for several groups of arboreal mammals were determined including sloths, New World monkeys, coatis, arboreal porcupines and, for the first time as a host of any Triatominae, tayras. A thorough review of previously documented sylvatic hosts, organized by triatomine species and the type of observation (associational, antibody-based, or DNA-based), is presented in a phylogenetic context and highlights large gaps in our knowledge of Triatominae biology.ConclusionThe application of DNA-based methods of host identification towards additional species of Triatominae, including rarely collected species that may require use of archival specimens, is the most efficient and promising way to resolve recognized shortfalls.
