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

Abstract

Ecological niche modelling was used to predict the potential geographical distribution 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 . Our results confirm these predictions and reinforce the idea that the identification of these species in these areas must be made with the aid of morphometric [41][42] and molecular methods 43 due to morphological similarities between these species.…”

Climatic factors influencing triatomine occurrence in Central-West Brazil

“…A greater number of synanthropic triatomine species was observed in areas with greater seasonal temperature variation. Other studies have shown temperature to be an important determinant of the distribution of triatomines on a regional or continental scale (Gorla 2002, Rodriguero & Gorla 2004, Batista & Gurgel-Gonçalves 2009, Gurgel-Gonçalves & Silva 2009, Gurgel-Gonçalves et al 2011). However, other environmental variables, such as the slope of the terrain (Leite et al 2011) and humidity (Arboleda et al 2009), have also been identified as principal determinants of the occurrence of certain species.…”

“…Apresenta-se o mapeamento geográfico das 65 espécies de triatomíneos que ocorrem no Brasil, incluindo limites da distribuição conhecida e a distribuição potencial, que pode ser predita usando a modelagem de nicho ecológico. Essa abordagem tem sido usada nos últimos anos para analisar a distribuição geográfica de triatomíneos e vem produzindo bons resultados , Gorla 2002, Lópe-z-Cárdenas et al 2005, Sandoval-Ruiz et al 2008, Gurgel-Gonçalves & Cuba 2009, Gurgel-Gonçalves & Silva, 2009, Arboleda et al 2009, Ibarra-Cerdeña et al 2009, Batista & Gurgel-Gonçalves, 2009). …”
