Abstract(s)
O mosquito Aedes albopictus, conhecido vulgarmente como Mos2017-2019quito
Tigre Asiático, é um mosquito invasor procedente da região Ásia-Pacífico.
Esta espécie é importante em saúde pública e veterinária devido
ao seu papel na transmissão de diversos agentes patogénicos, nomeadamente
os arbovírus chikungunya, dengue e Zika. Introduzido e estabelecido
ao longo da costa mediterrânica europeia, incluindo Espanha
desde 2004, este mosquito vetor tem sido responsável pelos surtos
autóctones de arbovírus que têm ocorrido na Europa desde 2007. Em
Portugal, o Ae. albopictus foi detetado pela primeira vez no âmbito da
Rede de Vigilância de Vetores (REVIVE) em dois eventos de introdução
independentes, na região norte em 2017 e no Algarve em 2018. O presente
estudo teve como objetivo caracterizar a distribuição geográfica
e atividade sazonal da espécie invasora Ae. albopictus em Portugal. A
vigilância ativa foi significativamente incrementada pela REVIVE após
estas deteções. Foram utilizadas armadilhas específicas para mosquitos
adultos (Biogents Sentinel traps) e para as fases imaturas (Ovitraps)
para determinar a sua distribuição geográfica e sazonal, abundância e
avaliar o processo de estabelecimento e dispersão da espécie a nível
regional e nacional. Estes dados são indispensáveis no planeamento
estratégico de medidas de controlo vetorial para evitar a dispersão das
populações de mosquitos vetores e prevenir surtos de doenças associadas
a Ae. albopictus.
The mosquito Aedes albopictus, also known as the Asian Tiger Mosquito, is an invasive mosquito from the Asia-Pacific region. This species is important in public and veterinary health due to its role in the transmission of several pathogens, namely the arboviruses chikungunya, dengue and Zika. Introduced and established along the European Mediterranean coast, including Spain since 2004, this vector mosquito has been responsible for the autochthonous arboviruses outbreaks that have been occurring more and more frequently in the European region since 2007. In Portugal, Ae. albopictus was detected for the first time by the Vector Surveillance Network (REVIVE) in two independent introduction events, in the northern region in 2017 and Algarve in 2018. The aim of the present study was to characterize the geographic distribution and seasonal activity of the invasive species Ae. albopictus in Portugal. Active surveillance was significantly increased by the REVIVE after these detections. Specific traps were used for adult mosquitoes (Biogents Sentinel traps) and for the immature stages (ovitraps) to determine its geographical and seasonal distribution, abundance and evaluate its way of establishment and dispersion at a regional and national level. These data are necessary in the strategic planning of vector control measures to avoid the dispersion of these populations of vectors and prevent outbreaks of vector-borne diseases.
