  1. Reported numbers represent means of 5 replicates
  2. Figures in parenthesis are percentages of egg hatching inhibition in comparison with control of distilled water
  3. Different letters in the same column indicate significant differences (P ≤ 0.05) according to Duncan’s multiple range test
  4. \( \mathsf{Egg}\ \mathsf{hatching}\ \mathsf{inhibition}\ \left(\%\right)=\frac{\mathsf{Control}-\mathsf{treatment}}{\mathsf{Control}}\times \mathsf{100} \)
