Control (deionized water) – nil mortality. LC₅₀, lethal concentration that kills 50% of the exposed larvae; LC₉₀, lethal concentration that kills 90% of the exposed larvae, LCL, lower confidence limit; UCL = upper confidence limit; df, degree of freedom; χ², chi-square values are significant at P < 0.05 level. Mean value of five replicates.
