Book Description
According to the European Plant Protection Organization, the pinewood nematode (PWN), Bursaphelenchus xylophilus is a quarantine organism at the top of the list of the pathogenic species. PWN may be found in North America (Canada, USA and Mexico) and in East Asia (Japan, Korea, China and Taiwan) and has a highly destructive capability towards conifers, in a relatively short time, causing serious economic damage in Japan, China and Korea. This nematode surveying is extremely important and a correct identification of nematode species associated with conifers is essential. Several conifers species are very susceptible (Pinus sylvestris, Pinus nigra and Pinus pinaster), the last one (maritime pine) is a particulary important economic specie in Portugal, and in southern Europe. In 1999, this nematode was found and identified for the first time in Portugal and in Europe. During 1999 and 2000, the Portuguese government, following an alert provided to European Community officials initiated an extensive national survey. During 2000 and 2001, research has been carried out regarding the morphobiometric as well as molecular (DNA: ITS-RFLP) characterization of the collected populations, as well as closely related species of Bursaphelenchus. The book details the Proceedings of an international workshop held at the University of Évora in 2001, covering all major aspects of the bioecology of the pinewood nematode (PWN), Bursaphelenchus xylophilus, its insect vectors and effects on the tree. Topics covered are: global issues and national surveys; morphology and molecular methods of identification of PWN; ecology and epidemiology; quarantine issues; tree physiology, resistance and histopathology; biology of PWN and relationships to its cerambycid vectors; control methods. General quarantine and political views are also presented.

Book Description
Pine forests face a global threat of pine wilt disease, which is being spread by vector beetles carrying pathogenic nematodes from dead trees to healthy ones. Among the host pines there are varying degrees of susceptibility, and nematode strains also contain a variety of virulences, both of which factors help to determine whether infected host trees will die or survive. As well, biotic and abiotic environmental factors influence the fate of infected trees. This book describes the history of the disease, pathogenic nematodes, vector beetles, the etiology and ecology of the disease, microorganisms involved, and control methods that utilize host resistance and biological control agents. Concrete, comprehensive, and the most up-to-date knowledge about this worldwide forest epidemic is presented for readers, enabling them to understand the nature and epidemic threat of pine wilt disease.

Book Description
On top of a decade of exacerbated disaster loss, exceptional global heat, retreating ice and rising sea levels, humanity and our food security face a range of new and unprecedented hazards, such as megafires, extreme weather events, desert locust swarms of magnitudes previously unseen, and the COVID-19 pandemic. Agriculture underpins the livelihoods of over 2.5 billion people – most of them in low-income developing countries – and remains a key driver of development. At no other point in history has agriculture been faced with such an array of familiar and unfamiliar risks, interacting in a hyperconnected world and a precipitously changing landscape. And agriculture continues to absorb a disproportionate share of the damage and loss wrought by disasters. Their growing frequency and intensity, along with the systemic nature of risk, are upending people’s lives, devastating livelihoods, and jeopardizing our entire food system. This report makes a powerful case for investing in resilience and disaster risk reduction – especially data gathering and analysis for evidence informed action – to ensure agriculture’s crucial role in achieving the future we want.

Book Description
The pinewood nematode is an important forest pest because it causes wilting and considerable tree mortality, particularly in Japan. It was first reported in Manitoba in 1982, although there are no cases of tree mortality in Canada. It is ranked in the first level as a potentially important pest internationally and the Scandinavian countries have restricted the importation of conifer chips and timber from countries where the pest is known to occur, a major concern of Canadian forest managers and lumber exporters. In 1985, the Forest Insect and Disease Survey began a nationwide survey to determine the distribution of the pinewood nematode. This report briefly reviews its history and biology and presents the results of the Canadian survey.
