Number of surviving nematodes showing delay in development treated with Artocarpus camansi extract. A, shows the development of L4 nematodes after exposure to the extract within 24 hours (day 1). B shows the resumption of the development of L4 nematodes progressing to young adult (48 hours/day 2) and C, to fully developed adult (72 hours/day 3) together with other nematodes of different larval stages also developing to higher stages. Each bar denotes the mean number of the developmental stages in each concentration with standard error mean. Different letters above the bars denote statistically significant differences between concentrations and contrary for the bars with the same letters.
