"International Symposium on Pine Wilt Disease"; Nanjing, China; 20-23 July 2009. Pine wilt disease has become a worldwide thread to forest ecology and international trade. Human activities involving the movement of wood and wood products may be considered the single most important factor in the long range spread of the causal agent, the Pinewood Nematode. Despite the dedicated and concerted actions of government agencies of all countries suffering from the disease, this disease continues to spread.  Research on systematics, diagnostics of the nematode and biology, ecology and modeling of the insect vectors, physiology and resistance of the host tree and interactions between the nematode and its associated microbe has progressed since the 2006 IUFRO Symposium on PWN in Lisbon, Portugal. The new findings and novel technology on the disease have contributed or will contribute to reduce its damage and thus protect our forest ecosystems and forest economy. The objectives of this symposium are to summarize the most recent progress on scientific research and management of the disease and to encourage information exchange internationally among the scientists and decision makers.
