India has witnessed a five-fold increase in dengue incidence in the past decade. However, the nation-wide distribution of dengue vectors, and the impacts of climate change are not known. Species distribution models are a novel approach for determining the distribution of species based on biologically relevant environmental factors, and relies on known presence and absence locations of the species. The Global Biodiversity Information Facility (GBIF) contains 562 records of Aedes aegypti occurrence and 207 records of Aedes albopictus occurrence in India, most of which are derived from a large scale study that compiled the global geographic database of Aedes aegypti and Aedes albopictus locations up to 2014, based on peer reviewed literature, national entomological surveys and expert networks. However, there was a need to update the occurrence locations after 2014. To overcome this knowledge gap, we compiled data on the occurrences of Aedes aegypti and Aedes albopictus in India, based on published literature after 2014 that carried out entomological surveys in India. This dataset was combined with data from GBIF to map the present and future distributions of Aedes aegypti and Aedes albopictus in India based on different scenarios for climate change.

An extensive survey of all dengue entomological studies conducted in India after 2014 was carried out. The search terms ‘India’, ‘aegypti’ and ‘albopictus’ were used to find relevant peer reviewed literature in NCBI - PubMed (https://www.ncbi.nlm.nih.gov/pubmed), Science Direct (https://www.sciencedirect.com/) and grey literature in Google Scholar https://scholar.google.com/). Only those studies were included where the exact coordinates of the survey were clearly mentioned. In total, 128 new occurrence locations of Aedes aegypti and 127 occurrence locations of Aedes albopictus were obtained. The data was then compiled in the Darwin core format.
