The demand for wood as raw material for construction, pulp and paper or energy industries which is likely to increase was estimated to reach 150 million m³ per year by the year 2000, even though the production of wood up to now only ranged from 23.9 to 61.6 million m³year (Saleh et al., 1990). To overcome this situation the government of Indonesia through the Department of Forestry has implemented a Five Year Plan (Pelita IV) to increase the production by the establishment of forest plantations (Forest Timber Estate) which should reach 6.2 million ha until Pelita VII (Soemarsono, 1989).
The species established in forest timber estates consist of local and exotic species such as Tectona grandis, Pinus merkusii, Dalbergia latifolia, Acacia mangium, A. auriculiformis,Eucalyptus spp., Paraserianthes falcataria, Swietenia macrophylla, Shorea spp., etc. Since most of the forest timber estate plantations were established by a monoculture system, pests and diseases occur and require prevention and control.
A list of the forest pests and diseases attacking fruits/seeds, leaves, stems and the root system is presented in this report.
