A Model of Termite Internal State for Understanding of Caste Differentiation Mechanism

摘要

Eusocial insects form colony so that they can adapt environmental fluctuations. Colony is maintained with caste differentiation, which is a self-organized task allocation. We researched termite caste differentiation. Termites have several specialized castes. The pseudergate, one of those has some differentiation possibilities. Moreover, it is suggested that Juvenile Hormone (JH) is concerned in termite caste differentiation. Our research emphasized focus on the relationship between the pseudergate caste differentiation and time evolution of JH titer so that we built the model of termite internal state through development for understanding of caste differentiation mechanism. Additionally, we built the model of the caste differentiation in termite colony. Mathematical analysis of the model with dynamical system conduced comprehensive property of the model. In addition, the model of termite internal state were evaluated with computer simulation.
