Herein, we describe Lutzomyia (Trichophoromyia) nautaensis n. in Lutzomyia auraensis Mangabeira captured in the southern Peruvian Amazon indicates the potential of this and other zoophilic sand flies for human disease transmission, particularly in areas undergoing urban development. In this region of Peru, cutaneous leishmaniasis is transmitted primarily by anthropophilic sand flies however, zoophilic sand flies of the subgenus Trichophoromyia may also be incriminated in disease transmission. sp., was collected in the northern Peruvian Amazon Basin.

Since the 1930s, several numbers of populations have been collected from the Peruvian Amazon and maintained as ex situ germplasm repositories in. The Peruvian Amazon harbors a large number of diverse cacao populations. USDA-ARS?s Scientific Manuscript databaseĬacao (Theobroma cacao L.) is indigenous to the Amazon region of South America. ![]() Molecular characterization of an earliest cacao (Theobroma cacao L.) collection from Peruvian Amazon using microsatllite DNA markers We highlighted some successful Y chromosome lineages expansions originated in Peru during the pre-Columbian history which involved both Andeans and Amazon Arawak people, showing that at least a part of the Amazon rainforest did not remain isolated from those exchanges. The Peruvian Amazon is home to an array of populations with differential rates of genetic exchanges with their neighbors and with the Andean people, depending on their peculiar demographic histories. The genetic structure follows the divide between the Andes and the Amazon, but we found a certain degree of gene flow between these two environments, as particularly emerged with the Y chromosome descent cluster's (DCs) analysis. We detected a high degree of genetic diversity in the Peruvian Amazon people, both for mtDNA than for Y chromosome, excepting for Cashibo people, who seem to have had no exchanges with their neighbors, in contrast with the others communities. We analyzed four Peruvian Amazon communities (Ashaninka, Huambisa, Cashibo, and Shipibo) for both Y chromosome (17 STRs and 8 SNPs) and mtDNA data (control region sequences, two diagnostic sites of the coding region, and one INDEL), and we studied their variability against the rest of South America. East of the Andes: The genetic profile of the Peruvian Amazon populations.ĭi Corcia, T Sanchez Mellado, C Davila Francia, T J Ferri, G Sarno, S Luiselli, D Rickards, OĪssuming that the differences between the Andes and the Amazon rainforest at environmental and historical levels have influenced the distribution patterns of genes, languages, and cultures, the maternal and paternal genetic reconstruction of the Peruvian Amazon populations was used to test the relationships within and between these two extreme environments. ![]()
