Ecological aspects of Rhodnius nasutus Stål, 1859 (Hemiptera: Reduviidae: Triatominae) in palms of the Chapada do Araripe in Ceará, Brazil

Abstract

The aim of this work is to present aspects related to the ecology of Rhodnius nasutus

Synanthropic triatomines (Hemiptera, Reduviidae) in the state of Pernambuco, Brazil: geographical distribution and natural Trypanosoma infection rates between 2006 and 2007

“…Rhodnius nasutus predominates in the Caatinga in the northeast region in different tree species, especially palm trees [37][38] ; however, this triatomine can colonize different peridomestic ecotopes as shown by Sarquis et al 39 . Despite these differences, the co-occurrence of R. neglectus and R. nasutus in some states in the Northeast Brazil, including Pernambuco, was predicted 40 .…”

Ecological niche modelling and differentiation between Rhodnius neglectus Lent, 1954 and Rhodnius nasutus Stål, 1859 (Hemiptera: Reduviidae: Triatominae) in Brazil

“…and Syagrus olera- cea (Mart.) Becc., which have a wide distribution in the caatinga and cerrado biomes (Bento et al 1992, Dias et al 2008. Moreover, the colonisation of this triatomine in another tree species (Licania rigida Benth.)…”

“…Occurrence records for R. nasutus and R. neglectus -The distributional data for R. nasutus were obtained from Lent (1948), Lent (1954), Lucena and Lima-Borba (1977), Lent and Wygodzinsky (1979), Silveira et al (1984), Pinto and Bento (1986), Carcavallo et al (1999), Galvão et al (2003), Sarquis et al (2004), Dias et al (2008), Lima and Sarquis (2008) and Abad-Franch et al (2009). Distributional data for R. neglectus were obtained from Gurgel-Gonçalves and Cuba (2009).…”

Infestation of Palm Trees by Triatomines (Hemiptera: Reduviidae) in the State of Bahia, Brazil

“…In Brazil, high rates of palm infestation by triatomines have been reported (barretto et al 1969;MiLes et al 1983;diotaiuti & dias 1984;Pinto & bento 1986;bento et al 1992;teixeira et al 2001;gurgeL-gonçaLves et al 2004a;sarquis et al 2004;dias et al 2008;abad-Franch et al 2009;dias et al 2010). Moreover, palm trees provide shelter and food for several vertebrates; some of them often sleep and nest in the crown, which favors the maintenance of a steady blood supply for triatomines in this environment (teixeira et al 2001;gurgeL-gonçaLves & cuba 2007;dias et al 2010).…”
