Abstract:
Nitric oxide is an important signaling molecule to be involved in olfaction, vision, touch, development and defensive behavior. The distribution of nitric oxide synthase (NOS) in the brain of Polyrhachis vicina was observed by using NADPH diaphorase (NADPH-d) histochemical technique. The results indicate that NOS is distributed in the mushroom bodies, the lobes, the central complex, midbrain and hind brain. According to the above mentioned results, NOS may influence the seeing, olfaction, memory and behaviors of ants.
