| Research Abstract |
We carried out experiments and investigations to elucidate the mechanisms of nymph/worker caste differentiation in termites. Cross experiments using two Reticulitermes species strongly suggested that this genus shared a same genetic caste determination (GCD) system. This genetic effect was not detected in Parrhinotermes. Worker-inducing pheromone was probably low-volatile and effective during 1st and 2nd instars. Alate sex ratios of Reticulitermes in the field possibly affected by the GCD system. We found a sex-specific AFLP marker and examined its characteristics.
