Abstract

The Red Palm Weevil (RPW), Rhynchophorus ferrugineus (Olivier, 1790) is insect pest to plants of the family Palmaceae. No study has been reported on the digestive mechanism of Red Palm Weevil (RPW). Salivary glands are responsible in the feeding regulation of insect while serotonin and dopamine play a significant role in the regulation of this gland. It is great to see the morphology of the salivary gland and how dopamine and serotonin possibly play their role in this gland. Two variation of RPW, striped and spotted RPW were chosen. The morphology of the gland of both RPW variants examined by using light microscopy was found to be a tubular type. Immunohistochemical analysis conducted showed that serotonin and dopamine in both variations did not innervate the glands suggesting they are not act as neurotransmitter. However, it can be detected on few areas within the glands. This suggests that serotonin and dopamine may act as a hormone because there is no evidence on the nerve fibers. The role of these biogenic amines in the salivary gland of RPW needs further investigation. Hopefully the data would help in understanding the mechanism of salivary glands control by biogenic amines in RPW specifically and insects with sucking mouthpart generally.
