GLOBAL OCCURRENCE PATTERNS OF AEDES MOSQUITOES BASED ON BIODIVERSITY DATABASE RECORDS

Abstract

Mosquitoes of the genus Aedes are widely distributed and play an important ecological and public health role as vectors of several arboviral diseases. Understanding their global distribution is essential for ecological assessment and vector surveillance. In this study, occurrence records of Aedes mosquitoes were obtained from the Global Biodiversity Information Facility and analyzed to evaluate global distribution patterns. After data cleaning and filtering, a total of 69,541 occurrence records from 188 countries were included in the analysis. Country-wise assessment revealed that the highest number of records originated from the United States, followed by Spain, Italy, Mexico, and Australia. Spatial visualization demonstrated a widespread global distribution, with higher concentrations in tropical and subtropical regions. The findings highlight the extensive geographic range and ecological adaptability of Aedes mosquitoes and demonstrate the usefulness of open biodiversity databases for large-scale ecological studies. This study provides a data-driven overview of Aedes distribution and supports the integration of biodiversity informatics into vector monitoring and public health research.
