“…Restricted gene flow and genetic structure of An. triannulatus COI lineage G in this region support a common phylogeographic pattern in mosquitoes and in some other similarly distributed species, such as sandflies [83]. An alternative explanation is that the most extensive An.…”

BackgroundThe molecular phylogenetic relationships and population structure of the species of the Anopheles triannulatus complex: Anopheles triannulatus s.s., Anopheles halophylus and the putative species Anopheles triannulatus C were investigated.MethodsThe mitochondrial COI gene, the nuclear white gene and rDNA ITS2 of samples that include the known geographic distribution of these taxa were analyzed. Phylogenetic analyses were performed using Bayesian inference, Maximum parsimony and Maximum likelihood approaches.ResultsEach data set analyzed septely yielded a different topology but none provided evidence for the seption of An. halophylus and An. triannulatus C, consistent with the hypothesis that the two are undergoing incipient speciation. The phylogenetic analyses of the white gene found three main clades, whereas the statistical parsimony network detected only a single metapopulation of Anopheles triannulatus s.l. Seven COI lineages were detected by phylogenetic and network analysis. In contrast, the network, but not the phylogenetic analyses, strongly supported three ITS2 groups. Combined data analyses provided the best resolution of the trees, with two major clades, Amazonian (clade I) and trans-Andean + Amazon Delta (clade II). Clade I consists of multiple subclades: An. halophylus + An. triannulatus C; trans-Andean Venezuela; central Amazonia + central Bolivia; Atlantic coastal lowland; and Amazon delta. Clade II includes three subclades: Panama; cis-Andean Colombia; and cis-Venezuela. The Amazon delta specimens are in both clades, likely indicating local sympatry. Spatial and molecular variance analyses detected nine groups, corroborating some of subclades obtained in the combined data analysis.ConclusionCombination of the three molecular markers provided the best resolution for differentiation within An. triannulatus s.s. and An. halophylus and C. The latest two species seem to be very closely related and the analyses performed were not conclusive regarding species differentiation. Further studies including new molecular markers would be desirable to solve this species status question. Besides, results of the study indicate a trans-Andean origin for An. triannulatus s.l. The potential implications for malaria epidemiology remain to be investigated.

“…Recently the genetic structure of seven populations from Brazil Northeastern region was described based on polymorphism analysis of 24 RAPD-PCR loci (de Queiroz Balbino et al 2006). Although the detected levels of genetic variation were higher than those obtained with the use of isoenzyme markers, genetic distances were considered to be compatible with those found between members of a single species.…”

“…Equally interesting from the data compiled in this table is that it is only within Brazil where broadly separated Lu. longipalpis populations have been considered either a single species (Mukhopadhyay et al 1997, 1998a,b, Mutebi et al 1999, Azevedo et al 2000, Arrivillaga et al 2003, de Queiroz Balbino et al 2006 or a species complex (Ward et al 1983, 1988, Yin et al 1999, Souza et al 2002, Bauzer et al 2002a,b, Maingon et al 2003, Bottecchia et al 2004, Hamilton et al 2004, Watts et al 2005) depending on the markers used. Therefore the controversy concerning the existence of a complex is centred on data from Brazilian populations.…”

“…Genetic and/or phenetic markers have been used to study the patterns of spatial structuring among vectors of Chagas disease (Abrahan et al 2008, Pérez de Rosas et al 2008), malaria (Brochero et al 2010), dengue (Scarpassa et al 2008), leishmaniasis (de Queiroz Balbino et al 2006), and African trypanosomiasis (Bouyer et al 2007). Morphometric techniques are based on empirical evidence showing greater similarity between parental lines and their offspring than between nonrelated individuals (Dujardin et al 1997b, 2007; Dujardin and Slice 2007).…”

Microgeographic Spatial Structuring of <I>Triatoma infestans</I> (Hemiptera: Reduviidae) Populations Using Wing Geometric Morphometry in the Argentine Chaco

We investigated the occurrence of spatial structuring in Triatoma infestans (Klug) (Hemiptera: Reduviidae) populations 12 yr after the last community-wide insecticide spraying campaign in rural Pampa del Indio, in the Gran Chaco of northeastern Argentina. In total, 172 male and 149 female right wings collected at 16 georeferenced sites with at least 10 individuals of the same sex were analyzed using geometric morphometry. Mean female body length and wing centroid size (CS) were significantly larger than for males. Log-transformed CS and length were significantly and positively correlated both for males and females. Males collected in domiciles had significantly smaller CS than those collected in peridomestic structures both closed (kitchens or storerooms) or open (chicken coops), in agreement with our previous results elsewhere in the dry Argentine Chaco. Female wing CS was not significantly different between ecotopes. Wing shape analyses showed the occurrence of significant geographic structuring in males and females combined and in males only. Male wings showed a strong association between Mahalanobis distance and geographic distance. In general, Mahalanobis distances were significantly different between collection sites located >4 km apart. For collection sites located <4 km apart, the greater the geographic distance the larger the difference in wing shape variables. Among females, only a partial correspondence between geographic groups and Mahalanobis distances was recorded. The strong spatial structuring found in T. infestans populations may be useful for the identification of putative reinfestation sources after vector control interventions.
