Average percentage mortality of Eudocima materna larval instars (3rd, 4th and 5th) after exposure to Heterorhabditis indica at the rate of 10, 25, 50, 100 and 200 infective juveniles (IJs) per larval concentrations. Error bars indicate standard error of mean (SEM). Different lower case letters above bars indicate statistical significance among different IJ concentrations after 24 h of treatment. Different upper case letters above bars indicate statistical significance among different IJ concentrations after 48 h of treatment (P ≤ 0.05, Duncan’s test)
