“…Ae. albopictus eggs can remain viable in the environment for long periods of time due to their ability to become dormant through two processes of quiescence and diapause, a characteristic which contributes to their dispersal and hinders control actions [ 6 ], making it the most important species in the transmission and maintenance of dengue fever outbreaks, along with Ae. aegypti .…”

(1) Background: Few studies to date have assessed the influences induced by climate change on the spatial distribution and population abundance of Aedes albopictus using the latest climate scenarios. In this study, we updated the current distribution of Ae. albopictus mosquitoes and evaluated the changes in their distribution under future climate conditions, as well as the risk of dengue virus emergence in Romania. (2) Methods: Under the two scenarios: High scenario (HS) when no drastic measures to reduce the effects of global warming will be taken, or they are not effective and low scenario (LS) when very stringent greenhouse control measures will be implemented. (3) Results: The results estimate an increase in temperatures in Romania of up to 2.6 °C in HS and up to 0.4 °C in LS, with an increase in the period of virus replication within the vector from June to October in HS and from May to September in LS. Moreover, in 2022, Ae. albopictus was reported in a new county, where it was not identified at the last monitoring in 2020. (4) Conclusions: The rapid spread of this invasive species and the need to implement monitoring and control programs for the Aedes population in Romania are emphasized.

Introducción. Aedes albopictus es un vector de arbovirus como dengue, Zika, chikungunya y fiebre amarilla. Los primeros reportes en el continente americano datan de 1985 y dada su capacidad de adaptación ecológica y fisiológica, se ha distribuido rápidamente en el territorio colombiano desde su primer reporte en 1998.Objetivo. Determinar la distribución de A. albopictus en las comunas de Ibagué, Colombia.Materiales y métodos. Los muestreos se realizaron entre mayo y noviembre de 2022 en zonas con abundante vegetación de las 13 comunas de Ibagué. Se emplearon aspiradores y redes entomológicas. Los mosquitos fueron transportados al Laboratorio de Investigaciones en Parasitología Tropical de la Universidad del Tolima para su determinación taxonómica.Resultados. Se identificaron 708 ejemplares de A. lbopictus, distribuidos en las comunas de Ibagué. La mayor abundancia del vector se presentó en las comunas 10, 11, 7, 8, 2 y 9. Las comunas 3, 4, 5, 6, 12 y 13 presentaron abundancias relativas cercanas al 3 %, y la comuna 1 tuvo una abundancia del 2 %.Conclusiones. Aedes albopictus está distribuido en todas las comunas de Ibagué, probablemente su dispersión se ha visto favorecida por las condiciones ambientales y sociales de esta región. Se recomienda hacer seguimiento anual a las poblaciones de este vector y realizar una caracterización molecular de los arbovirus encontrados. Además, el conocer la distribución de este mosquito en la ciudad permitirá focalizar las estrategias de control entomológico y prevenir futuros brotes de arbovirosis.
