How effective is copper sulfate pentahydrate as a larvicide against juvenile Aedes aegypti mosquitoes?

Label:chem

Topic
Copper sulfate pentahydrate is a commonly used chemical in water treatment due to its antimicrobial properties. It has been shown to be effective against both Gram-negative and Gram-positive bacteria. This study examines whether copper sulfate pentahydrate, at concentrations safe for human consumption, can reduce the survival and emergence of Aedes aegypti larvae.
Answer
Copper sulfate pentahydrate was effective in reducing the survival and emergence of juvenile Aedes aegypti mosquitoes. At concentrations of 300, 600, and 1200 μg/L, copper sulfate pentahydrate significantly decreased the number of larvae that survived and emerged into adult mosquitoes. The highest concentration tested (1200 μg/L) resulted in an 87.19% inhibition of emergence by day 16. This indicates that copper sulfate pentahydrate can be a viable option for vector control in water storage containers while maintaining water safety.
