| Outline of Final Research Achievements |
Animal feeding behavior is controlled by bioactive factors and hormones from brain and central nervous system. So far, scientists, however, have not answered the question "What to eat?" We are addressing such instinctive behavioral mechanisms using an insect, the two-spotted cricket. Infrastructure for analyses of nutrient preference behavior has been generated as well as techniques of molecular biology. We now know the fact that hormones can regulate the systems of feeding behavior and that metabolisms in the peripheral tissues such as adipose tissue can modify them. Further, we depicted the network constituted by hormones, implying that we are now ready to obtain the evaluation system for the network constituted by hormones and metabolisms. Based on the current research, we hope that the behavioral prediction counted by the evaluation system of hormone network is upcoming in the near future.
