Geographical distribution and intra-domiciliary capture of sylvatic triatomines in La Convención province, Cusco, Peru

Abstract

SUMMARYThe geographical distribution and intra-domiciliary capture of sylvatic triatomines in three districts of the province of La Convención, Cusco, Peru are presented. In the district of Vilcabamba, eight adults of Rhodnius pictipes and five adults of Panstrongylus geniculatus were found. In the district of Ocobamba, 19 adults, 14 nymphs, and eggs of P. rufotuberculatus were found. In the district of Echarate, six adults and 10 nymphs of Eratyrus mucronatus, an adult of R. pictipes and P. geniculatus, and a nymph of P. rufotuberculatus were also found. The geographical distribution of E. mucronatus has extended to Cusco. This is the first report in Peru of household colonization by this triatomine.

Triatominae species of Suriname (Heteroptera: Reduviidae) and their role as vectors of Chagas disease

“…Rhodniini Pinto, 1926, R. pictipes Stål, 1872 - R. pictipes is a widespread silvatic species that is frequently attracted to light and is known to enter houses on occasion (Lent & Wygodzinsky 1979, Torres & Cabrera 2010). It is the most common species collected in Suriname and was often collected in domestic habitats.…”

“…The one specimen found by the NZCS was collected in a recreational room at Brownsberg Nature Park, an ecotourist site situated at 500 m above sea level in a humid tropical forest. Its role as a vector of Chagas disease is considered insignificant (Barrett 1991), but evidence of domestic capture exists (Torres & Cabrera 2010). Distribution: districts of Paramaribo, Brokopondo (Brownsberg) and Para (Zanderij).…”

Eratyrus mucronatus Stål, 1859 (Hemiptera: Reduviidae: Triatominae): first report in the State of Acre, Brazil, and updated geographic distribution in South America

“…Furthermore, detection of infected colonies of E. mucronatus in houses and peridomiciles has been observed in Bolivia (Noireau et al 1995;Depickère et al 2012), Colombia (Guhl 2007), Peru (Torres and Cabrera 2010) and Venezuela (Rojas et al 2008) indicating the potential risk of transmission of T. cruzi to humans. Thus, it is important to record the locations where E. mucronatus has been detected in domiciles, as well as update the geographic distribution of this species and predict areas of potential occurrence.…”

“…The importance of E. mucronatus as a potential vector of T. cruzi to humans has been highlighted in Bolivia, Peru and Venezuela (Rojas et al 2008;Torres and Cabrera 2010;Depickère et al 2012). The new record of E. mucronatus in domicile in Brazil is further evidence of the synanthropic potential of this species.…”

“…The insect was sent to the Laboratory of Entomology of Rio Branco, Acre, and identified as E. mucronatus ( Figure 1 Data on the occurrence of E. mucronatus were obtained from Lent and Wygodzinsky (1979), Silveira et al (1984), Rebelo et al (1998), Soto Vivas et al (2001, Chávez (2006), Guhl et al (2007), Cortez et al (2007), Rojas et al (2008), Serrano et al (2008), Castro et al (2010), Morocoima et al (2010), Torres and Cabrera (2010), Meneguetti et al (2011), Depickère et al (2012). Records of E. mucronatus in collections of Rodolfo Carcavallo and Herman Lent at the National and International Reference Laboratory on Triatomine Taxonomy at the Oswaldo Cruz Institute, FIOCRUZ, were analyzed.…”
