| Research Abstract |
The purpose of the project was to establish the mass culture of wood-attacking anobium beetles, which are the most important pests for wooden cultural materials in Japan. In addition, we tried to develop the monitoring protocols regarding wood-attacking insects in wooden cultural buildings together with a research on biological and chemical characteristics of aged wood.
Though the mass culture of Nicobium species has not been obtained yet, but we have succeeded in establishing the laboratory mass culture of Heterobostrychus aequalis with the artificial diet of Lyctus beetles. This is the first success in Japan. Future ecological studies with mass cultured insects are strongly expected.
The aged pine timbers were surveyed for their anti-termite and anti-fungal performance in combination with the cheimical analyses. The results suggested that some extractives were converted into the oxidized forms by the aging, and they had higher anti-biodegradation activities.
