What is the larvicidal effect of sodium hypochlorite on juvenile Aedes aegypti mosquitoes?

Label:chem

Topic
Sodium hypochlorite is a widely used disinfectant in water treatment processes due to its strong oxidizing properties, which eliminate a broad range of waterborne pathogens. This study assesses the efficacy of sodium hypochlorite, at concentrations safe for human consumption, in reducing the survival and emergence of Aedes aegypti larvae.
Answer
Sodium hypochlorite was highly effective in reducing the survival and emergence of juvenile Aedes aegypti mosquitoes. At concentrations of 500, 1000, and 2000 μg/L free chlorine, sodium hypochlorite significantly decreased the number of larvae that survived and emerged into adult mosquitoes. The highest concentration tested (2000 μg/L) achieved an 80.65% inhibition of emergence by day 16. This suggests that sodium hypochlorite can be an effective larvicide for controlling Aedes aegypti populations in water storage containers while ensuring water safety for human consumption.
