The Culex pipiens complex in continental Portugal: distribution and genetic structure.

  • Autores: Almeida AP, Donnelly MJ, Gomes B, Novo MT, Parreira R, Pinto J, Sousa CA
  • Ano de Publicação: 2012
  • Journal: Journal of the American Mosquito Control Association
  • Link: http://www.ncbi.nlm.nih.gov/pubmed/?term=The+Culex+pipiens+complex+in+continental+Portugal%3A+Distribution+and+genetic+structure.

Portugal is a southern European country that displays favorable ecological conditions for the establishment of West Nile virus (WNV) transmission cycles. Competent mosquito vector species are present throughout the country.

Aedes aegypti on Madeira Island (Portugal): genetic variation of a recently introduced dengue vector. Memórias do Instituto Oswaldo Cruz

  • Autores: Campos M, Novo MT, Pinto J, Reyes-Lugo M, Ribolla PEM, Salgueiro P, Seixas G, Silva AC, Sousa CA, Spenassatto C
  • Ano de Publicação: 2013
  • Journal: Memorias do Instituto Oswaldo Cruz
  • Link: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0074-02762013000900003

The 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 history and the genetic diversity of this insular vector population.

Following the identification of two autochthonous cases of dengue type 1 on 3 October 2012, an outbreak of dengue fever has been reported in Madeira, Portugal.

Mosquito surveys and West Nile virus screening in two different areas of southern Portugal, 2004-2007

  • Autores: Almeida AP, Alves R, Esteves A, Freitas FB, Novo MT, Rodrigues JC, Sousa CA
  • Ano de Publicação: 2010
  • Journal: Vector-Borne and Zoonotic Diseases
  • Link: http://www.ncbi.nlm.nih.gov/pubmed/?term=Mosquito+Surveys+and+West+Nile+Virus+Screening+in+two+Different+Areas+of+Southern+Portugal

Longitudinal mosquito surveys were carried out in southern Portugal from 2004 to 2007, in a wetland area (Comporta, District of Setúbal) and around the perimeter of a dam irrigation plant that created the largest artificial lake in Europe, 250 km(2) (Alqueva, Districts of Evora and Beja).

Anopheles atroparvus density modeling using MODIS NDVI in a former malarious area in Portugal.

  • Autores: Almeida AP, Lopes P, Lourenço PM, Novo MT, Seixas J, Sousa CA
  • Ano de Publicação: 2011
  • Journal: Journal of Vector Ecology
  • Link: http://www.ncbi.nlm.nih.gov/pubmed/?term=Anopheles+atroparvus+density+modeling+using+MODIS+NDVI+in+a+former+malarious+area+in+Portugal.

Malaria is dependent on environmental factors and considered as potentially re-emerging in temperate regions. Remote sensing data have been used successfully for monitoring environmental conditions that influence the patterns of such arthropod vector-borne diseases.

Species Composition and WNV Screening of Mosquitoes from Lagoons in a Wetland Area of the Algarve, Portugal.

  • Autores: de Almeida AP, Esteves A, Freitas FB, Novo MT
  • Ano de Publicação: 2011
  • Journal: Frontiers in physiology
  • Link: http://www.ncbi.nlm.nih.gov/pubmed/?term=Species+Composition+and+WNV+Screening+of+Mosquitoes+from+Lagoons+in+a+Wetland+Area+of+the+Algarve%2C+Portugal

The aim of this study was to evaluate mosquito abundance, species diversity, larval and adult population dynamics in seven lagoons integrated in the wetland coastal system of the Algarve, Portugal, in the summer of 2007, as well as the screening of these for West Nile virus (WNV).

Larvicidal Activity Against Aedes aegypti of Foeniculum vulgare Essential Oils from Portugal and Cape Verde

  • Autores: Delgado M, Figueiredo AC, Matos O, Moiteiro C, Novo MT, Rocha DK
  • Ano de Publicação: 2015
  • Journal: Natural Product Communications
  • Link: http://www.ncbi.nlm.nih.gov/pubmed/25973508

Dengue is a potentially fatal mosquito-borne infection with 50 million cases per year and 2.5 billion people vulnerable to the disease. This major public health problem has recurrent epidemics in Latin America and occurred recently in Cape Verde and Madeira Island. The lack of anti-viral treatment or vaccine makes the control of mosquito vectors a high option to prevent virus transmission.

Larvicidal, molluscicidal and nematicidal activities of essential oils and compounds from Foeniculum vulgare

  • Autores: Almeida MTM, Cunha AC, Ferreira MF, Novo MT, Rosa JS. R, Silva CA, Sousa RMOF
  • Ano de Publicação: 2014
  • Journal: Journal of Pest Science
  • Link: http://link.springer.com/article/10.1007%2Fs10340-014-0628-9

Plant-based products, namely essential oils (EOs), are environmentally friendly alternatives for the control of disease vectors, hosts and/or parasites. Here, we studied the general toxicity and biopesticidal potential of EOs and phenylpropanoids from Foeniculum vulgare var. vulgare (bitter fennel), a perennial plant well adapted to temperate climates.

Satellite-derived estimation of environmental suitability for malaria vector development in Portugal

  • Autores: Almeida APG, Benali A, Freitas FB, Lima JC, Lourenço PM, Novo MT, Nunes JP, Seixas J, Sousa CA
  • Ano de Publicação: 2014
  • Journal: Remote Sensing of Environment
  • Link: http://www.sciencedirect.com/science/article/pii/S0034425714000273

This work focused on determining the current relationships between environmental factors and the density of the former malaria vector Anopheles atroparvus in Portugal, a previously endemic country. Adult females were sampled and vector density was estimated in 22 sites in Southern Portugal between 2001 and 2010 and related with land cover and satellite-derived air temperature and vegetation indices. The relationship between vector density and local larval habitat, temperature and, in a broader sense, to environmental suitability, was assessed using a statistical modelling approach.
