First record of tiger mosquito, Aedes albopictus (Diptera: Culicidae), in La Rioja: public health implications.
In 2016, an annual entomological surveillance program for the detection of Aedes albopictus in the autonomous community of La Rioja was established. In the summer of 2020, the presence of eggs was detected for the first time in an urban area, which constitutes the first record of this species in the region. The identification of this invasive mosquito implies a change in the risk of occurrence of arbovirus cases in La Rioja. Entomological surveillance is crucial for the design of control strategies that, together with epidemiological surveillance, can prevent the appearance of autochthonous arbovirus outbreaks. This work is a detailed description of the first detection of tiger mosquito in La Rioja, as well as the completed interventions, and the perspectives for the future.
