| Outline of Final Research Achievements |
In this study, double-stranded RNA (dsRNA) having complementary sequence of hexamerin mRNA related to juvenile hormone transport and protection was produced in large quantities using genetic recombination technology. By RNA interference (RNAi) using feeding method, we examined decrease in hexamerin mRNA, reduction of hexamerin protein expression, and control of termite caste differentiation. Also, we examined the possibility of colony downfall of termite due to the imbalance of the proportion of workers, soldiers, and nymphs (future alates) caused by differentiation control using RNAi.
