| Research Abstract |
Termite society contains individuals of different castes. In this reserch project, we revealed that the caste fate (nymph or worker) of Reticulitermes termites was determined by the interactions between an X-linked caste determination gene and a worker-inducing pheromone produced by reproductives. Genetic effects were detected for the sensitivities to the pheromone. Direct aggressive behavior probably has an important role in the caste ratio regulation.
