Geographic distribution and morphometric differentiation of Triatoma nitida usinger 1939 (Hemiptera: Reduviidae: Triatominae) in Guatemala

Abstract

Triatoma nitida was found in 14 (0.4%)

Environmental determinants of the distribution of Chagas disease vectors in south-eastern Guatemala

“…The former two species are considered the principal Chagas disease vectors in the country based on their distribution and vector capacity (Schofield and Dujardin, 1997;Monroy et al, 2003c). T. nitida appears to have less vector importance due to its scarce presence in domestic habitats and inefficient defecation patterns (Monroy et al, 2003b). However, an increasing number of T. nitida colonizations in domestic and peridomestic habitats in north-central Guatemala have been documented recently (Monroy et al, 2003b).…”

“…T. nitida appears to have less vector importance due to its scarce presence in domestic habitats and inefficient defecation patterns (Monroy et al, 2003b). However, an increasing number of T. nitida colonizations in domestic and peridomestic habitats in north-central Guatemala have been documented recently (Monroy et al, 2003b). Nation-wide surveys have shown that T. dimidiata is distributed in 21 of the 22 provinces in Guatemala (Monroy et al, 2003c).…”

“…R. prolixus was initially detected in 9 provinces by the Ministry of Health (MoH) of Guatemala, but the species is abundant only in the provinces of Zacapa and Chiquimula (Monroy et al, 2003c). T. nitida has been found in 9 provinces in Guatemala (Monroy et al, 2003b). The preferred microhabitats for T. dimidiata are unplastered adobe walls with cracks, and this vector species is often found under bed mattresses (Monroy et al, 1996(Monroy et al, , 1998.…”

“…thatched grass roofs) (Monroy et al, 1998) and only occasionally under bed mattresses. T. nitida has been found in adobe walls in houses and chicken coops (Monroy et al, 2003b).…”

Multivariate Discrimination Between Two Cryptic Haemagogus Species Associated with the Transmission of Yellow Fever Virus in the Americas

“…Within the morphological context, morphometry (Rohlf & Marcus 1993;Adams et al 2004) appears as an important taxonomic tool for species discrimination and species variations (Dujardin et al 1997(Dujardin et al , 1998Calle et al 2002;Jaramillo et al 2002;Monroy et al 2003;Belen et al 2004;Lehmann et al 2005;Yurtas et al 2005;Feliciangeli et al 2007). Delgado & RubioPalis (1993) examined the morphometric variation of Anopheles (Nyssorhynchus) nuneztovari Gabaldón and detected variability within Venezuelan populations.…”
