| Outline of Final Research Achievements |
The mechanism for the mineral and the water supply of the economically important pest, Coptotermes formosanus and Incisitermes minor was elucidated in order to establish a new termite control method. For the mineral utilization, the tolerance to copper in I. minor was supposed to be higher than that in C. formosanus by measuring the mineral content in each part of termite body and the taste response to copper ion. For the water utilization, it was found in C. formosanus that aqaporin is expressed predominantly in the salivary gland of the workers and not detected within that of soldiers, as a result of investigating the distribution of aquaporin in the digestive system of each caste. In addition, the function of the salivary gland and water-sac was completely different in β-glucosidase activity, i.e. it was active in the salivary gland but not in the water-sac, despite of the same role as water keeper.
