2P2-I22 シロアリのカースト分化モデルと環境適応(移動知)

Eusocial insects form colony, and they can adapt environmental fluctuations by the colony. Colony is maintained with caste differentiation, which is a self-organized task allocation which raise the efficiency of the colony. Termites have several specialized castes. Pseudergate, one of castes, becomes some different castes. Our purpose are building the internal model and elucidating caste differentiation mechanism. The model is based on biological knowledge. It is suggested that Juvenile Hormone (JH) is concerned in termite caste differentiation, so our research emphasized focus on the relationship between the pseudergate caste differentiation and time evolution of JH titer. The model includes growth in developmental processes and has the time variation of JH affected by the environment. Additionally this model has two interactions: trophallaxis and caste differentiation inhibition. The termite internal state model was evaluated with computer simulation.
