(LC50) concentration that kills 50% of population, (LC90) concentration that kills 90% of population, (LCL) lower confidence limit, (UCL) upper confidence limit, χ2 Chi-square, The Holm-Sidak post hoc test was used to examine the data after a one-way ANOVA. The results were displayed as Mean ± SE of three replicates, with P < 0.05, n = sample size, and means in the same column denoted by distinct letters differing substantially.
