This study primarily investigates the effects of different concentrations of pomelo peel solutions on mosquito larvae. Pomelo peels were separated into outer and inner peels, and varying concentrations were added to water. Changes in mosquito larvae's heart rate, survival rate, wriggling frequency, and breath-holding time were observed. Additionally, pH levels and dissolved oxygen levels in the mosquito larval habitat were measured to assess the impact of different concentrations of pomelo peel solutions on mosquito larvae. Results indicated that the outer peel solution affected breath-holding time and survival rate. The wriggling frequency increased more in response to the outer peel solutions than to the inner peel solutions. Outer peel solution also increased heart rate. In summary, the outer peel solution had more pronounced effects on mosquito larvae in various aspects compared to the inner peel solution. Based on the experiments, we recommend using a 0.45% concentration of pomelo outer peel solution for mosquito larvae control.
