| Outline of Final Research Achievements |
Long-term temperature-humidity monitoring and the chemical analysis of the nest surface of a drywood termite, Incisitermes minor, were performed in order to clarify the characteristics of the nest environment. As a result, higher temperature resulted in accelerated its metabolism and increased the quantity of water transpiration from their body surface. Moreover, the cuticular hydrocarbons were detected from the wood surface of the nest, indicating the addition of water repellency to the nest surface. It is suggested that I. minor is able to survive inside the dry woods without supply of liquid water, so that I. minor might prevent dryness by keeping the humidity inside the nest higher, by transpiring moisture from the body surface and with water-shedding coating of the cuticular hydrocarbons to the nest surface inside.
