“…For example, it is known that virtually all species of the genus Rhodnius are primarily associated with palms, the genus Panstrongylus with burrows and tree cavities and the genus Triatoma with terrestrial rocky habitats or rodent burrows (Gaunt & Miles 2000). Considering the rapid adaptation to new environments and the accelerated process of domiciliation by many kissing-bug species (Noireau et al 2005), future studies will need to define "sylvatic" habitats using more ecologically sound criteria because, from the kissing-bug perspective, some of these habitats could be considered more peridomiciliary than sylvatic. Ecologically based categories for peridomEcologically based categories for peridomiciliary habitat classification are also necessary because, for some kissing-bug species, the peridomicile could be considered sylvatic because species are not colonizing new habitats; however, humans are becoming part of the kissing-bug species natural habitat.…”

Host use by vectors is important in understanding the transmission of zoonotic diseases, which can affect humans, wildlife and domestic animals. Here, a synthesis of host exploitation patterns by kissing-bugs, vectors of Chagas disease, is presented. For this synthesis, an extensive literature review restricted to feeding sources analysed by precipitin tests was conducted. Modern tools from community ecology and multivariate statistics were used to determine patterns of segregation in host use. Rather than innate preferences for host species, host use by kissing-bugs is influenced by the habitats they colonise. One of the major limitations of studies on kissing-bug foraging has been the exclusive focus on the dominant vector species. We propose that expanding foraging studies to consider the community of vectors will substantially increase the understanding of Chagas disease transmission ecology. Our results indicate that host accessibility is a major factor that shapes the blood-foraging patterns of kissing-bugs. Therefore, from an applied perspective, measures that are directed at disrupting the contact between humans and kissing-bugs, such as housing improvement, are among the most desirable strategies for Chagas disease control.Key words: foraging -null models -diet analysis -multivariate statistics -Chagas disease -niche breadth Blood-feeding patterns of triatomines • Jorge Eduardo Rabinovich et al. 480 Several aspects of feeding-related behaviour in triatomines have also been well studied. Such aspects include feeding preferences (Quintal & Polanco 1977), avoidance of excessive warming during feeding (Lazzari et al. 2009), importance of nutritional status in flight initiation and dispersal (Lehane & Schofield 1982, Lehane et al. 1992, Noireau & Dujardin 2001, Emmanuelle-Machado et al. 2002, Ceballos et al. 2005, avoidance of predators during feeding (Bodin et al. 2009a, b), frequency and size of the blood intake (Maddrell 1963, Wood 1976, Montenegro & Pasina 1984, Maifrino et al. 1986, Pietrokovsky et al. 1996, Pereira et al. 1998, control of meal size (Bennet-Clark 1963b) and the relationship between feeding and defecation patterns as well as other aspects of feeding with epidemiological importance (Wood 1951, Dias 1956, Zeledón et al. 1970, 1977, Da Rocha e Silva et al. 1979, Crocco & Catalá 1996, Kollien & Schaub 1998, Zabala & D' Antonio 1988, Braga & Lima 1999, Aldana et al. 2001, Emmanuelle-Machado et al. 2002, Nattero et al. 2002, Almeida et al. 2003, Arévalo et al. 2007, Rodriguez et al. 2008, Klotz et al. 2009).Studies have been conducted on the relationship between the impacts of the triatomine feeding process and demographic parameters (Davies 1990, Malo et al. 1993, Emmanuelle-Machado et al. 2002, mortality and fecundity (Goodchild 1955, Hays 1965, Regis 1977, Patterson 1979, Catalá de Montenegro 1989, Braga et al. 1998, Braga & Lima 2001, Davey 2007, development time (Martinez-Ibarra et al. 2003, Martinez-Ibarra & Novelo-López 2004, resistance to starvation (Gajardo Tobar 1952,...

“…The stable occupation of thornbird nests (both by resident thornbirds and inquilines) probably provides a year-round blood supply for the bugs. This may even apply for nests that are not occupied by breeding birds, because P. tertius can also feed on invertebrate hemolymph (NOIREAU et al 2005), which are common in the nests of thornbirds (SILVA & LUSTOSA 1993, GURGEL-GONÇALVES et al 2006, DI IORIO & TURIENZO 2009). Thus, continuous food availability would favor the permanence of P. tertius in thornbird nests across the Brazilian Cerrado and Caatinga ecoregions.…”

Psammolestes tertius Lent & Jurberg, 1965 is a sylvatic triatomine bug species that occurs in thornbird nests in Brazil. We studied infestation of 527 nests of Phacellodomus rufifrons Wied, 1821 and Phacellodomus ruber Vieillot, 1817 by P. tertius in eight Brazilian states across the Cerrado and Caatinga ecoregions. Psammolestes tertius occurred in 44% of the nests, mainly in those of P. ruber. Overall, 3,261 specimens (52% nymphs) were captured, with an average of 14 bugs per infested nest (range 1-75). While P. tertius occurrence and age structure (percentage of nymphs) were similar in Cerrado and Caatinga nests, infestation intensity (bugs/infested nest) was higher in the Cerrado. Last-stage nymphs and adults were predominant in P. tertius populations from both P. ruber and P. rufifrons nests. The results indicate that Phacellodomus nests are favourable habitats for P. tertius in the open/dry ecoregions of Brazil. The percentage of adult P. tertius specimens (48%) was higher than that observed in other triatomine species (usually less than 5% under either experimental or natural conditions), suggesting that adult bugs tend to remain in thornbird nests. The stable blood supply provided by resident/breeding birds would favor steady P. tertius infestation of thornbird nests across Brazilian Cerrado and Caatinga ecoregions

“…It can occur in domestic, peridomestic, and silvatic habitats, frequently found in hen houses, corrals, nests of birds (Lent & Wygodzinsky 1979, Torrealba et al 1985, Carcavallo et al 1997, nests of small mammals (Torrealba et al 1985), pig pens (Lent & Wygodzinsky 1979), and pigeon coops, although its natural ecotope seems to be palm tree crowns and dry trees (Carcavallo et al 1997). T. pseudomaculata is also found in hollows and under the bark of dry trees (Noireau et al 2005). It is also a species of secondary epidemiological importance, often found in peridomestic habitats associated with domestic fowl (Silveira & Rezende 1994, Borges et al 1999, Sarquis et al 2006.…”

Due to morphological similarities between Triatoma maculata and T. pseudomaculata, which comprise the "maculate complex", both had been regarded as the same species until 1964. Considering that the studies on triatomine hybridization permit hypotheses formulation concerning origin and divergence of species, enabling a quantitative analysis of taxonomic relationships between species, the present investigation was aimed at broadening further understanding related to the capacity of hybrid production by determining the degree of reproductive isolation between T. maculata and T. pseudomaculata. Our results have demonstrated that T. maculata and T. pseudomaculata showed no differences regarding reproduction patterns and they are able to cross, generating infertile hybrids.
