Water quality characteristics may influence whether mosquito larvae are present in a water body. Public parks often contain diverse water features that may differ in environmental conditions. This study aimed to compare water quality between water bodies with mosquito larvae and those without mosquito larvae at Thara Public Park, Krabi Province, Thailand. Water bodies within the park were surveyed during December and January. Mosquito larvae were collected and identified, and water quality parameters, including dissolved oxygen, pH, temperature, and salinity, were measured. The results showed differences in water quality between water bodies with and without mosquito larvae. Water bodies with mosquito larvae generally exhibited lower dissolved oxygen levels compared to those without larvae. Other water quality parameters showed overlapping ranges between the two groups. These findings suggest that water quality characteristics, particularly dissolved oxygen, may be associated with mosquito larval presence based on the variables examined in this study.
