Values are mean percentage±standard deviation of five replications. F-values are based on one way ANOVA for individual instars. For 2nd instar the value of 200 and 250 mg/L concentrations of C. didymobotrya ethanol extract are not included for Chi-square analysis. Within the column similar alphabets are not statistically significant by LSD (P>0.05).
