The purpose of this project is to investigate the Aedes mosquito size in natural sources and pH, The hatching rate, survival rate, life cycle and size of mosquitoes by visiting the region to investigate natural mosquito breeding areas. Set up six containers in the lab, three for each experiment, with a pH 4 to 9. Fill with ten mosquito eggs, then regulate the temperature. The mosquitoes had the longest average length in nature is pH 8. The highest incubation rate, pH 6 and pH 7. Mosquitoes at the larval stage had the longest survival rates in pH 7 and 8 and did not able to flourish at pH 9. The Aedes mosquito's life cycle at pH 7 and could not grow at all in pH 9. Furthermore, it was discovered that mosquitoes in both the larval and larval stages had the longest average lengths in pH 7. Additionally, when comparing the length of mosquitoes in the nature and a study assessing the size of insects in natural water with varying pH values agreed with each other. The size of Aedes mosquitoes is influenced by the pH of the water. The longest larvae were discovered to have the highest average length among those at pH 7. The size tends to shrink in acidic water. The average length was comparable in the larvae stage, with the adult stage at pH 7 having the longest average length, and pH 5 having the smallest average length. It was discovered that there is a continuous relationship between the two: Aedes mosquito sizes decrease when water pH approaches an acidic level.
