Influence of climatic and land use factors on post-monsoon distribution of Aedes mosquito vectors in Udupi taluk.

ABSTRACT: Vector-borne diseases (VBDs) account for 17% of the global disease burden, causing approximately 700,000 deaths annually. Among these, dengue is a major public health concern in tropical and subtropical regions, transmitted primarily by Aedes aegypti and Aedes albopictus. This cross-sectional observational study was conducted in Udupi taluk, Karnataka, India, to examine the influence of climatic factors and land use/land cover (LULC) on Aedes distribution during the post-monsoon season. With a 5 km × 5 km grid sampling design, 28 locations (560 households) were surveyed between October and December 2023. Aedes larvae were detected in 71.42% of houses. Of the 425 mosquitoes identified, A. albopictus (57.64%) were more abundant than A. aegypti (23.52%), with the rest belonging to Culex and A
