Origin and expansion of the mosquito Aedes aegypti in Madeira Island (Portugal)
Rocha Seixas, Gonçalo Filipe; Salgueiro, P; Bronzato-Badial, A.; Gonçalves, Y.; Reyes-Lugo, M.; Gordicho, Vasco; Ribolla, Paulo; Viveiros, BelaHistorically known as the yellow fever mosquito, Aedes aegypti invaded Madeira Island in 2005 and was the vector of the island's first dengue outbreak in 2012. We have studied genetic variation at 16 microsatellites and two mitochondrial DNA genes in temporal samples of Madeira Island, in order to assess the origin of the invasion and the population structure of this mosquito vector. Our results indicated at le...
Aedes aegypti on Madeira Island (Portugal): genetic variation of a recently int...
Seixas, Gonçalo; Salgueiro, Patrícia; Silva, Ana; Campos, Melina; Spenassatto , Carine; Reyes_Lugo, Matias; Novo, Maria Teresa Lourenço MarquesThe increasing population of Aedes aegypti mosquitoes on Madeira Island (Portugal) resulted in the first autochthonous dengue outbreak, which occurred in October 2012. Our study establishes the first genetic evaluation based on the mitochondrial DNA (mtDNA) genes [cytochrome oxidase subunit I (COI) and NADH dehydrogenase subunit 4 (ND4)] and knockdown resistance ( kdr ) mutations exploring the colonisation hist...
Seasonal population dynamics and the genetic structure of the mosquito vector A...
Campos, Melina; Spenassatto , Carine; Macoris, Maria; Paduan , Karina; Pinto, João Pedro Soares da Silva; Ribolla, PauloPopulation genetic studies of insect vectors can generate knowledge to improve epidemiological studies focused on the decrease of pathogen transmission. In this study, we used nine SNPs across the Aedes aegypti genome to characterize seasonal population variations of this important dengue vector. Mosquito samples were obtained by ovitraps placed over Botucatu SP from 2005 to 2010. Our data show that, regardless...
