Aedes mosquito distribution across urban and peri-urban areas of Kinshasa city, Democratic Republic of Congo

In the Democratic Republic of Congo (DRC) Aedes mosquitoes are principal vectors of medically important arboviruses, with major implications for yellow fever, chikungunya and dengue. However, systematic surveillance of these species remains limited, constrained by competing public health priorities such as malaria and other neglected tropical diseases. This gap in surveillance prevents the rapid detection of changes in the distribution, abundance and behaviour, particularly in rapidly urbanizing environments where breeding habitats are proliferating and ecological conditions are favourable for the establishment of these vectors. To address this gap, spatially explicit, small-scale data on Aedes populations in urban and peri-urban areas are needed to accurately assess transmission risk and develop targeted, evidence-based vector control strategies. Here, we present a geo-referenced dataset of 6,577 entomological occurrence records collected in 20224 throughout urban and peri-urban areas of Kinshasa city, DRC, using Larval dipping, Human landing catches, Prokopack aspirator, and BG-Sentinel traps. Records include Aedes albopictus (n = 2,694), Aedes aegypti (n = 1939), Aedes vittatus (n = 2), and Aedes spp. (n = 1,942), each annotated with species, sex, life stage, reproductive status, and spatial coordinates. The dataset is published as a Darwin Core archive in the Global Biodiversity Information Facility (GBIF), and represents the most detailed, spatially explicit record of Aedes mosquito occurrence in Kinshasa to data, providing a robust foundation for entomological and modelling research to support data driven arbovirus vector control strategies in DRC.

Species Composition and Distribution of Anopheles gambiae Complex Circulating in Kinshasa

Understanding the distribution of Anopheles species in a region is an important task in the planning and implementation of malaria control programmes. This study was proposed to evaluate the composition and distribution of cryptic species of the main malaria vector, Anopheles gambiae complex, circulating in different districts of Kinshasa. To study the distribution of members of the An. gambiae complex, Anopheles were sampled by CDC light trap and larva collection across the four districts of Kinshasa city between July 2021 and June 2022. After morphological identification, an equal proportion of Anopheles gambiae s.l. sampled per site were subjected to polymerase chain reaction (PCR) for identification of cryptic An. gambiae complex species. The Anopheles gambiae complex was widely identified in all sites across the city of Kinshasa, with a significant difference in mean density, captured by CDC light, inside and outside households in Kinshasa (p=0.002). Two species of this complex circulate in Kinshasa: Anopheles gambiae (82.1%) and Anopheles coluzzii (17.9%). In all study sites, Anopheles gambiae was the most prevalent species. Anopheles coluzzii was very prevalent in Tshangu district. No hybrids (Anopheles coluzzii/Anopheles gambiae) were identified. Two cryptic species of the Anopheles gambiae complex circulate in Kinshasa. Anopheles gambiae s.s., present in all districts and Anopheles coluzzii, with a limited distribution. Studies on the ecology of the larval sites are essential to better understand the factors influencing the distribution of members of the An. gambiae complex in this megalopolis.

Data from Entomological Collections of Aedes (Diptera: Culicidae) in a post-epidemic area of Chikungunya, City of Kinshasa, Democratic Republic of Congo

Arbovirus epidemics (e.g. Chikungunya, dengue, West Nile, Yellow Fever, and Zika), are a growing threat in Africa in areas where Aedes (Ae.) aegypti and A. albopictus are present. The lack of complete sampling of these two vectors limits our ability to understand their propagation dynamics in areas at risk from arboviruses. Here, we describe for the first time the geographical distribution of two arbovirus vectors (Ae. aegypti and Ae. albopictus) in a chikungunya post-epidemic zone in the provincial city of Kinshasa, Democratic Republic of Congo between 2020 and 2022. In total 6,943 observations were reported using larval capture and human capture on landing methods. These data are published in the public domain as a Darwin Core archive in the Global Biodiversity Information Facility. The results of this study potentially provide important information for further basic and advanced studies on the ecology and phenology of these vectors, as well as on vector dynamics after an epidemic period.
