| Outline of Final Research Achievements |
We have identified the factors modulating insect feeding behavior in the silkworm, so far. Becaus of the data which no crucial factor capable of controlling feeding behavior havet been identified, we assumed that a hormone network should modulate the motivation of feeding behavior in insects. To address the hormone network at a molecular level, we have investigated several basic analyses during this project. As results, we have identified receptors for ITP (ion transport peptide: functional unknown peptide), and unknown peptide factors GSRYamides. In addition, brain-gut peptides can modulate feeding behavior like other animal systems via controlling intestinal metabolisms.
Now, we are generating a network graph for hormones modulating feeding behavior. That evaluation method will contribute to further understanding the hormone network-modulating feeding behavior.
