  1. LC50 and LC90: lethal concentration that kills 50 and 90% of the exposed C. pipiens larvae; UCL: upper confidence limit; LCL: lower confidence limit; X2 = Chi-square, p < 0.05, significance level, Mean value of five replicates, (SE) standard error. Control (distilled water), nil mortality. Letters indicate degree of significant based on Tukey’s HSD tests between different treatments and control. Letter (a) mean high significant, and letter (c) mean low significant, while the same letters are not significantly different
