The effect of 5-hydroxytryptophan (5-HTP), a 5-HT precursor, on feeding and locomotion behaviors. (a) 5-HTP (5 mM and 25 mM) significantly reduced the body wall contractions in larvae. (b) When the larvae were fed on food mixed with 5-HTP, no significant difference was observed in feeding behavior in comparison to control animals (CS). (c) Body length significantly decreased at 25 mM 5-HTP. One-way ANOVA was used for comparison, and Bonferroni t-test was employed to compare treatments with control group. Data represented as mean ± SEM. P value < 0.05 is significant.
