This research examined mosquito control strategies in Krabi, Thailand, focusing on the negative environmental impacts of traditional pesticides. The study explored the role of aquatic predatory insects in controlling mosquito larvae populations and assessed the effect of distance from the dam on mosquito and predator diversity. The study area was divided into three sites: (1) Boon Siam Hotel, (2) Panurat Prachasan Temple, and (3) Kaew Korawaram Temple. Results revealed the presence of Aedes albopictus larvae at Boon Siam Hotel sites and Culex larvae in all sites, with the highest numbers found at Boon Siam Hotel. Seven types of water containers were identified: earthen jars, drainage, puddles, bromeliads, plant pots, fountains, and buckets. Pottery containers (jars, water tanks, etc.) exhibited the highest number of mosquito larvae. Five mosquito aquatic predators were identified: water striders, small water striders, fish, amphibians, gastropods, and bloodworms. A total of 107 containers were categorized based on material (0:25:26:56 metal: plastic: earthen: plant), presence of lids (2:105 with lids: without lids), container type (4:103 natural: artificial), and water levels (39:9:19:40 25:50:75:100%). Most mosquito aquatic predators were found in water with temperatures ranging from 29-32°C, pH levels of 7.0-8.2, and water salinity of 0.1-1.5. Mosquito larvae were found in water with temperatures ranging from 30-33°C, pH levels of 8.0-8.2, and water salinity of 0.4-2.5. These findings offer valuable insights into the distribution of breeding sites and water parameters near Boon Siam Hotel, highlighting potential areas for targeted vector control measures to mitigate mosquito-borne diseases.
