jean-bernard.duchemin@pasteur.fr 2026-04-09 eng Mangroves are natural and dynamic forest ecosystems that grow in tropical intertidal zone. In French Guiana, occurrences of mosquitoes (Diptera: Culicidae) in these habitats remain largely understudied. This dataset has been designed to document standardized sampling events with the relative abundance of species recorded across a variety of coastal and estuarine mangrove habitats. It compiles 21,765 mosquito occurrence records from 334 sampling events conducted between October 2023 and July 2025, and is open to updates and additional data. Its aim is to improve knowledge of mosquito species spatio-temporal distribution and assemblage composition in these coastal ecosystems.

The majority of the sampled sites were located in the region of Cayenne and its direct surroundings, extending for approximately 50 km alongshore and about 25 km inland. Approximately 100 km southeast of Cayenne, a second area was sampled in the Oyapock river mouth at the boundary with Brazil along an upstream-downstream transect about 30 km long between Trois-Palétuviers and Ouanary. However, data from new mangrove sites sampled in the future may be added to the dataset. -52.569734 -51.645382 5.09564 4.052539 2023-10-26 2025-07-11 The dataset under consideration concerns mosquitoes (Diptera: Culicidae). The identification of species is provided whenever possible. phylum Arthropoda family Culicidae class Insecta order Diptera kingdom Animalia The work done in the Cayenne region was part of the MAGELLAN Living Labs project, which is funded by the France 2030 program on Nature-based Solutions (ANR-22-EXSO-0002). The work done in the Oyapock region was part of the OYAMOUST project, led by the dataset author, and funded by the Oyapock Observatoire Hommes-Milieux (Labex DRIIHM/IRDHEI ANR-11-LABX-0010). I would like to thank the members of the Institut Pasteur de la Guyane Medical Entomology Unit of French Guiana for their help during field missions, for their contribution in identifying, and for their valuable review of this work throughout its development. I would like to extend my gratitude to Léa Ackerer from the Sepanguy association, Jonathan Simon from the National Reserve of Mont Grand Matoury, Ludovic Granjon from the CNRS and Maxime Dutour from the Institute of Research for Development, who also kindly helped me with my work in the field. The dataset may be updated to correct errors or to incorporate additional data generated as part of ongoing research activities. asNeeded Médie Collet Institut Pasteur de la Guyane, Institut de Recherche pour le Développement

mcollet@pasteur-cayenne.fr Field data were entered into a structured database linking sampling events to associated occurrence records. Taxonomic names were harmonized and unique identifiers were assigned to each event and occurrence. Data were standardized according to Darwin Core terms and formatted for publication through the GBIF IPT. The study was conducted in coastal and estuarine mangrove habitats of French Guiana, primarily around the Island of Cayenne and along the lower Oyapock River, between October 2023 and July 2025. Data from new mangrove sampling sites in the future may be added to the dataset. Mosquitoes were mainly collected during standardized sampling events conducted across different mangrove habitats. The following sampling protocol and setups were used : BG-Pro baited with BG-Sweetscent and CDC light traps were the two main sampling methods used. Usually, traps were for night trapping or day trapping, and occasionally both. At each site, traps were suspended about 1.5 m above the ground level at regular intervals along a transect from 30 m to 60 m. However, due to circumstances, not always the same setups were used at all sites, and the sampling plan was not always the same at all sites. Two larval dipping events were occasionally carried out and included in the dataset. The identification of species is provided whenever possible, or at the genus level at least, based on an examination of adult external features. In order to address the issue of uncertain identifications of Culicidae species, three legs of the right lateral side of a few specimens were carefully dissected and kept in a separate vial containing 96% ethanol and stored at -20°C for further molecular investigations. Whenever possible, they will be identified by DNA barcoding.
