Available in PDF, EPUB and Kindle. Book excerpt: Experiments were conducted in the greenhouse, field and growth chambers to evaluate effects of soil type, soil moisture regimes, and porosity on selected aspects of the dynamics of the Kona coffee root-knot nematode, Meloidogyne konaensis. First, the reproduction and damage potential of M. konaensis on resistant and susceptible rootstocks of coffee in four soils under two moisture regimes representative of areas where coffee is grown in Hawaii were assessed in greenhouse experiments. M. konaensis suppressed growth of coffee in all four soils. Nematode reproduction occurred readily in all soil types. Reproduction was lowest in the Hydric Dystrandept soil where the nematode holotype was found. In contrast, root galling was greatest in this soil. Greater galling occurred under constant moisture (33kPa) than under fluctuating moisture conditions in this soil. A field experiment in Kainaliu, Hawaii was conducted to determine the influence of irrigation, plant age, cultivar and nematode on coffee growth and yield. The population densities of the nematode in the soil varied according to plant age and irrigation treatment. Soil populations under irrigated conditions were greater during the months of May to July which normally follows the greatest annual precipitation and a period of active plant growth. Nematode reproduction was greater on coffee transplanted as 6-month-old seedlings than on coffee transplanted at 12- month ofage. Soil water tension varied by season and experimental treatment. Trees from 12-month-old transplants exhibited greater water tension fluctuation with greatest water tension occurring from January to April. Trees transplanted as 6-month-old seedlings into M. konaensis infested soil and irrigated yielded greater coffee fruit than the same aged trees treatment without irrigation. Crop loss and reduction of growth and yield were also more evident from 6-month-old seedlings without supplemental irrigation treatment. In contrast, yield from plots in trea.

This book was released on 2008-09-02 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: When I conceived this book, what I had in mind was what I did not know about coffee-parasitic nematodes (CPNs). Indeed, after reading many papers and several chapters in books, I felt far from having a comprehensive understanding of the subject. Not only would it be a daunting task to retrieve the numerous articles, reports, theses and dissertations on CPNs published since 1878, but it would also be impossible to learn, on my own, from all the enormous experience acquired by nematologists and coffee growers in so many countries. Therefore, this book is dedicated to those with restless minds, who want to know more about CPNs and their importance in coffee production worldwide. This book has been diligently written by top scientists in their areas of expertise or country, and it has been meticulously edited to guarantee precision without compromising an enjoyable read. I learned a lot from this book...I’m sure you will too. Finally, I’d like to thank Zuzana Bernhart from Springer, who believed in this project and decided to publish it; Susan Casement, who revised all chapters for grammatical correctness; and all the contributors, without whom this book would never have became a reality.

Download or read book Pine Wilt Disease written by Bo Guang Zhao and published by Springer Science & Business Media. This book was released on 2008-09-27 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Colonial Dis Ease written by Anne Perez Hattori and published by University of Hawaii Press. This book was released on 2004-07-31 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: A variety of cross-cultural collisions and collusions—sometimes amusing, sometimes tragic, but always complex—resulted from the U.S. Navy’s introduction of Western health and sanitation practices to Guam’s native population. In Colonial Dis-Ease, Anne Perez Hattori examines early twentieth-century U.S. military colonialism through the lens of Western medicine and its cultural impact on the Chamorro people. In four case studies, Hattori considers the histories of Chamorro leprosy patients exiled to Culion Leper Colony in the Philippines, hookworm programs for children, the regulation of native midwives and nurses, and the creation and operation of the Susana Hospital for women and children. Changes to Guam’s traditional systems of health and hygiene placed demands not only on Chamorro bodies, but also on their cultural values, social relationships, political controls, and economic expectations. Hattori effectively demonstrates that the new health projects signified more than a benevolent interest in hygiene and the philanthropic sharing of medical knowledge. Rather the navy’s health care regime in Guam was an important vehicle through which U.S. colonial power and moral authority over Chamorros was introduced and entrenched. Medical experts, navy doctors, and health care workers asserted their scientific knowledge as well as their administrative might and in the process became active participants in the colonization of Guam.

Available in PDF, EPUB and Kindle. Book excerpt: Aquatic microbial ecology, a growing interdisciplinary field, has become increasingly compartmentalized in recent years. The aim of this volume is to propose a framework for biochemical and molecular approaches, which are employed ever more widely in studies of aquatic microbial communities and ecosystem functioning. The book presents state of the art applications of modern molecular research techniques to a range of topics in ectoenzymes microbial carbon metabolism bacterial population dynamics RNA chemotaxonomy of microbial communities plasmids and adaptation to environmental conditions. Written for limnologists, marine biologists, and all researchers interested in environmental microbiology and molecular aspects of ecology, this volume will provide a stimulating introduction to this emerging field.
