Estrutura de populações de Rhodnius neglectus Lent e Psammolestes tertius Lent & Jurberg (Hemiptera, Reduviidae) em ninhos de pássaros (Furnariidae) presentes na palmeira Mauritia flexuosa no Distrito Federal, Brasil

Abstract: Rhodnius neglectus Lent, 1954 {Rn}e Psammolestes tertius Lent & Jurberg, 1965 {Pt} são triatomíneos que ocorrem em ninhos de aves, principalmente da família Furnariidae. O ciclo biológico dessas espécies é conhecido em condições de laboratório, sendo poucos estudos em ecótopos silvestres. Para analisar a infestação e estrutura de populações de Rn e Pt em ninhos de aves presentes na palmeira Mauritia flexuosa Linnaeus, em duas estações climáticas do Brasil Central, foram amostradas 41 palmeiras com evidênci… Show more

“…R. neglectus occurs predominantly in wild environments, inhabiting different species of palm trees in Brazil [51][52][53] . In DF it can be found in M. flexuosa palm trees 3,4,19 , and sporadic occurrence in the administrative regions of Planaltina, Sobradinho, Ceilândia, and São Sebastião may be associated with the presence of palm trees in peridomicile. The role of these peridomiciliary palm trees in the maintenance of triatomines in DF should be evaluated in future studies.…”

“…As DF is geographically placed inside the State of Goiás, T. costalimai and T. lenti may also occur in wild environments in DF. Psammolestes tertius is found in some administrative regions of DF, in nests of Phacellodomus ruber birds, which are present in the crowns of M. flexuosa palm trees 4,19 . Even though natural and experimental infection of Ps.…”

“…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.…”

“…Data on the occurrence of triatomine species in domiciliary environments between 1975-1983 were also taken into account (Silveira et al 1984), as were data from other studies (Silva & Lustosa 1993, Carcavallo et al 1999, 2002, Carcavallo & Jurberg 2000, Oliveira & Silva 2007, Almeida et al 2008, Gurgel-Gonçalves & Silva 2009, Gurgel-Gonçalves et al 2012b, Maeda et al 2012, Obara et al 2012). In addition, records of triatomines in the collections of Rodolfo Carcavallo and Herman Lent at the National and International Reference Laboratory on Triatomine Taxonomy at the Oswaldo Cruz Institute, Oswaldo Cruz Foundation, were analysed.…”

“…This palm tree is gorgeous and has a leafy canopy; thus, it is attractive to birds for nesting purposes and serves as a food source for R. neglectus. The presence of vertebrates such as mammals and birds within the palm is one of the factors for the establishment and growth of the triatomine colonies 14 . Future studies need to be performed in other seasons of the year, since the dynamics of these vertebrates is seasonal; such investigations might show associations of R. neglectus with different vertebrates present in Caçu, as reported for other regions 3,13,14 .…”
