Values represent mean of five replications; mortality of the after 24 h of exposure period; LC50= lethal concentration brings out 50% mortality; LC99= lethal concentration brings out 99% mortality; different letters (a, b, c, and d) within the same row; R2 = regression; = chi-squire; df = degree of freedom; significant at p<0.05.
