摘要

Background

The Asian tiger mosquito, Aedes albopictus (Skuse, 1894), is a highly invasive species that has successfully colonized many tropical and temperate regions worldwide. Its rapid global spread is strongly associated with human activities and has created favorable conditions for the emergence of human arboviruses in new geographic areas.

Methods

Mosquito larvae were collected by community health workers from different breeding sites and reared to adults in a field insectary. Adult mosquitoes were morphologically identified to species level. Species identification was confirmed by cytochrome oxidase subunit I DNA barcoding.

Results

We report the first detection of Aedes albopictus in Angola during an Anopheles stephensi survey conducted in Soyo, Zaire Province. Phylogenetic analysis indicated that the Angolan Ae. albopictus population clusters with sequences from Central African countries, suggesting an introduction from within the continent.

Conclusions

The presence of Ae. albopictus in Angola highlights the need for enhanced vector surveillance and control measures to prevent the emergence of arboviral diseases. This finding emphasizes the relevance of collaboration between local health authorities, communities, and international organizations in monitoring the spread of invasive mosquito species.
