UC: Untreated control; TC: Treated control. Values are mean of three replicates of three trials ± standard deviation. Different superscript alphabets within the column indicate
statistical significant difference in larval mortality between concentrations at P<0.05 level by one way ANOVA followed by Tukey’s test. |
