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.

Pine wilt disease (PWD) is unquestionably a major threat to forest ecosystems worldwide. After seriously affecting Eastern Asian countries, the challenge is now in Europe, following its detection in Portugal in 1999 and its subsequent spread. For foresters, these were really very bad news and, in order for adequate action to be taken, scientists had to teach politicians about the seriousness of the problem. That is never an easy task, but it was successfully done at that time, mainly by the continued effort of Professor Manuel Mota. The challenge of having political decisions based on good science is fundamental for the success of any program, but especially in dif?cult situations such as those arising by the introduction of harmful organisms in new ecosystems. The success of the dialogue between science and policy requires intelligent partners from each side, which is not always necessarily the case... Examples of lack of recognition of problems raised by science are unfortunately abundant throughout the history of science. The recent recognition of the efforts of the Intergovernmental Panel on Climate Change (IPCC) and Al Gore with the - bel Prize, and the continued failure in taking appropriate actions by major political players is a dramatic modern example of the dif?culty of this dialogue...

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.

Nematode interactions are important biological phenomena and of great significance in agriculture. It is a fascinating subject which is multidisciplinary by nature, and concerns any scientist involved with plant health. There have been marked advances in our knowledge of various aspects of the subject in the last two decades. This study area has been the subject of several reviews, but there was no exclusive text on the subject. This has stressed the need to document the information, developing a unifying theme which treated nematode interactions in a holistic manner. This book is about the inter action of plant-parasitic nematodes with other plant pathogens or root symbionts, the nature of their associations, their impact on the host and con sequential interactive effects on the involved organisms. Since nematodes are at the centre of the theme, the responsibility of understanding of other plant pathogens dealt with in this book is largely delegated to the reader. I have limited the book content to interactions with biotic pathogens and root symbionts only, for various reasons. The book embodies 16 chapters, and attempts to present balanced infor mation on various aspects of nematode interactions with other plant pathogens and root symbionts. Some chapters describe general aspects of the subject. Interactions of nematodes with specific groups of organisms are addressed in the remaining chapters.

Insects multiply. Destruction reigns. There is dismay, followed by outcry, and demands to Authority. Authority remembers its experts or appoints some: they ought to know. The experts advise a Cure. The Cure can be almost anything: holy water from Mecca, a Government Commis sion, a culture of bacteria, poison, prayers denunciatory or tactful, a new god, a trap, a Pied Piper. The Cures have only one thing in common: with a little patience they always work. They have never been known entirely to fail. Likewise they have never been known to prevent the next outbreak. For the cycle of abundance and scarcity has a rhythm of its own, and the Cures are applied just when the plague of insects is going to abate through its own loss of momentum. -Abridged, with insects in place of voles, from C. Elton, 1924, Voles, Mice and Lemmings, with permission of Oxford University Press This book is an enquiry into the "natural rhythms" of insect abundance in forested ecosystems and into the forces that give rise to these rhythms. Forests form unique environ ments for such studies because one can find them growing under relatively natural (pri meval) conditions as well as under the domination of human actions. Also, the slow growth and turnover rates of forested ecosystems enable us to investigate insect popula tion dynamics in a plant environment that remains relatively constant or changes only slowly, this in contrast to agricultural systems, where change is often drastic and frequent.

Wang has gathered contributions from an impressive cohort of the world’s most respected experts on longhorned beetles. Chapters review both basics of cerambycid taxonomy, mor- phology, and behavior (feeding, reproduction, and chemical ecology), as well as more applied concerns, such as laboratory rearing, pest control, and bio- security. Overall, this volume is a valuable contribution to the literature as a "one-stop shop" for readers seeking a comprehensive overview of longhorned beetles... It represents a tremendous effort on the part of Wang and the authors, and has resulted in a much-needed update to the literature. This volume is the only work of its kind available at this time, and is a valuable addition to the library of any scientist studying wood-boring beetles. - Ann M. Ray, Biology, Xavier University, Cincinnati, Ohio in The Quarterly Review of Biology, Volume 94, 2019 There are more than 36,000 described species in the family Cerambycidae in the world. With the significant increase of international trade in the recent decades, many cerambycid species have become major plant pests outside their natural distribution range, causing serious environmental problems at great cost. Cerambycid pests of field, vine, and tree crops and of forest and urban trees cost billions of dollars in production losses, damage to landscapes, and management expenditures worldwide. Cerambycidae of the World: Biology and Pest Management is the first comprehensive text dealing with all aspects of cerambycid beetles in a global context. It presents our current knowledge on the biology, classification, ecology, plant disease transmission, and biological, cultural, and chemical control tactics including biosecurity measures from across the world. Written by a team of global experts, this book provides an entrance to the scientific literature on Cerambycidae for scientists in research institutions, primary industries, and universities, and will serve as an essential reference for agricultural and quarantine professionals in governmental departments throughout the world.

The volume focuses on novel and effective biological and biotechnological methods for managing major plant parasitic nematodes in economically important agricultural crops. Nematodes develop a wide variety of interactions with soil microbes and host plants, and cause enormous losses in crop yields equivalent to around USD 173 billion annually. In view of growing concern for pesticide contamination in crops, coupled with ban on several efficacious pesticides, and increasing demand for organic foods, the biological and biotechnological approaches offer a good alternative to chemicals for managing nematode infestations in agricultural crops. The book embodies twenty-two chapters which are arranged in two groups. The first group covers different novel methods of nematode management such as biotechnological, biopesticides, microbial consortia, host resistance, omics technology, transgenics, nano-nematicides, nano-diagnosis, etc. The second groups of chapters describe important nematode problems in major crops such as cereals, vegetables, pulses, spices, wood yielding conifers, etc. Overall, the book collates the latest information on above topics and offers practical solutions to the limitations and challenges in the existing management technologies. This book is of interest and serves up-to-date and elaborated information to agriculture researchers, teachers, scientists, under-graduates, post-graduates, plant nematologists, plant pathologists, plant protectionists, agronomists, horticulturalists, helminthologists, extension workers, and NGOs.
