      Biology and Integrated Management of Turfgrass Diseases

      by Gary W. Beehag, Nathan R. Walker, Percy T.W. Wong, Jyri Kaapro

      Cultivated turfgrass is an assemblage of mown, perennial grasses or prostrate-growing forb plants and a suite of microbes all competing with each other in a common environment. This book approaches turfgrass diseases from an ecological perspective and explains with examples how wild plants and microbes have co-evolved. It addresses the identification, biology and integrated management of both common turfgrass diseases and newly emergent diseases. It includes the common and lesser-known turfgrass species, their surrounding environment and the range of beneficial and pathogenic microbes which in combination explain why disease occurs. For disease identification purposes, fungal diseases are arranged according to their predominantly cool season and warm season occurrence. Turfgrass bacterial and viral diseases, and plant parasitic nematodes are also covered. Written by a team of international authors, it combines technical expertise and practical experience. Essential for anyone involved in managing turfgrass, this book provides the know-how to identify the early warning signs of diseases, in order to manipulate the environment and minimise the damage.

      Biology and Management of the Formosan Subterranean Termite and Related Species

      by Nan-Yao Su, Chow-Yang Lee, Lauren Davies, Thomas Chouvenc, J. Kenneth Grace, Claudia Husseneder, Shuji Itakura, Hou-Feng Li, Nathan Lo, Kok-Boon Neoh, Wakako Ohmura, Faith M. Oi, Rudolf H. Scheffrahn, Qian Sun, Gaku Tokuda, Edward L. Vargo, Chia-Chien Wu, Koichi Yamamoto

      The Formosan subterranean termite, Coptotermes formosanus, is the most destructive and invasive termite species globally. It is also the only termite species listed in the world's 100 worst invasive alien species of the Global Invasive Species Database. Annually, its infestation costs more than $4 billion in control and damage repairs in the USA alone. This book is the first comprehensive resource drawing on all the literature on C. formosanus since Tokuichi Shiraki first described the species in 1909. The book covers the worldwide distribution of this species, its biogeography, and how it has dispersed from its native range in southern China and Taiwan to different parts of the world. It describes its present taxonomic status and discusses the species' biology, ecology, foraging behavior, physiology, chemical ecology and its association with symbionts. From a practical standpoint, the authors address all of the various management options for this species, such as baits, soil termiticides, wood preservatives, inspection and detection technologies, and Integrated Pest Management (IPM) approaches. Lastly, there are chapters dedicated to another important destructive species, Coptotermes gestroi (the Asian subterranean termite), and the recently discovered C. formosanus/C. gestroi hybrids. This important book is an essential and valuable reference for researchers, graduate students, pest management professionals, chemical manufacturer personnel, building and property managers, and others. It provides readers with a comprehensive understanding of the biology and management of the Formosan subterranean termite and the Asian subterranean termite.

      Biology of Mosquitoes, Volume 2

      Sensory Reception and Behaviour

      by Alan N Clements

      Mosquitoes are important as transmitters of widespread major diseases and as nuisance insects. They are also one of the most studied and well-known group of insects, both in the laboratory and in the field. The first volume in The Biology of Mosquitoes series is a key reference work and has received excellent reviews. This second title in the three volume series focuses on the functioning of the mosquito sense organs that provide them with information about the environment and that enable the adult females to find and attack their vertebrate hosts. It also reviews knowledge of the circadian rhythms and other internal mechanisms that regulate the onset and timing of different behaviours. This integrated review of the sensory mechanisms and behaviour of mosquitoes provides a unique insight into their biology. The contents, which are fully up-to-date, include much important work from the past which is often overlooked.

      Biology of Mosquitoes, Volume 3

      Transmission of Viruses and Interactions with Bacteria

      by Alan N Clements

      The great importance of mosquitoes lies in their role as transmitters of pathogens and parasites, and in their use as experimental animals well suited to laboratory investigations into aspects of biochemistry, physiology and behaviour. The largest part of this latest volume of The Biology of Mosquitoes concerns interactions between mosquitoes and viruses and the transmission of arboviruses to their vertebrate hosts, while the remainder concerns symbiotic interactions between mosquitoes and bacteria. The introduction provides a timely review of the first major development in mosquito taxonomy for several decades. Further chapters describe the interactions between mosquitoes and the viruses that infect them, the transmission and epidemiology of seven very important arboviruses, and the biology of bacteria that are important control agents or of great biological interest. Like the earlier volumes, Volume 3 combines recent information with earlier important findings from field and laboratory to provide the broadest coverage available on the subject.

      Biology and Breeding of Food Legumes

      by Geert Angenon, Ashwani K Basandrai, Judith Burstin, Steven B Cannon, S K Chaturvedi, H K Chaudhary, Percy Maruwa Chimwamurombe, Nazmul Haq, Manabu Ishitani, Shiv Kumar, Monika Lulsdorf, Michael Materne, Nobuko Ohmido, Klaus Oldach, Reid G Palmer, Marta Santalla, Jessica Schlueter, B B Singh, Mohar Singh, Carlos Roberto Spehar, Brijesh K Tiwari, Cenzig Toker, Rajeev K Varshney, Maria Wedzony, Asibuo James Yaw. Edited by Aditya Pratap, Jitendra Kumar.

      Food legumes are important constituents of human and animal nutrition, supplying high quality proteins crucial for a balanced diet. These crops also play an important role in low-input agricultural production systems by fixing atmospheric nitrogen. Despite systematic and continuous breeding efforts by legume researchers all over the world, substantial genetic gains have not been achieved. These issues require immediate attention, and overall, a paradigm shift is needed in breeding strategies to strengthen our traditional crop improvement programs. To this end, Biology and Breeding of Food Legumes provides extensive information on their history, origin, evolution and botany, as well as breeding objectives and procedures, nutritional improvement, industrial uses, post-harvest technology and recent developments made through biotechnological intervention.

      Invasion Biology

      Hypotheses and Evidence

      by Jonathan M. Jeschke, Tina Heger, Sabrina Amador-Vargas, Tim M. Blackburn, Raul Rennó Braga, Phillip Cassey, Simon Debille, Martin Enders, Felix Erhard, Alejandro G. Farji-Brener, Gordon A. Fox, Pablo García-Díaz, Lorena Gómez Aparicio, James Griesemer, Julie L. Lockwood, Christopher J. Lortie, Caroline Müller, Regina Nordheimer, Petr Pysek, Samuel M. Scheiner, Julian Starzer, Olena Torchyk, Jean Ricardo Simões Vitule

      There are many hypotheses describing the interactions involved in biological invasions, but it is largely unknown whether they are backed up by empirical evidence. This book fills that gap by developing a tool for assessing research hypotheses and applying it to twelve invasion hypotheses, using the hierarchy-of-hypotheses (HoH) approach, and mapping the connections between theory and evidence. In Part 1, an overview chapter of invasion biology is followed by an introduction to the HoH approach and short chapters by science theorists and philosophers who comment on the approach. Part 2 outlines the invasion hypotheses and their interrelationships. These include biotic resistance and island susceptibility hypotheses, disturbance hypothesis, invasional meltdown hypothesis, enemy release hypothesis, evolution of increased competitive ability and shifting defence hypotheses, tens rule, phenotypic plasticity hypothesis, Darwin's naturalization and limiting similarity hypotheses and the propagule pressure hypothesis. Part 3 provides a synthesis and suggests future directions for invasion research

      Tsetse Biology and Ecology

      Their Role in the Epidemiology and Control of Trypanosomosis

      by Stephen G A Leak

      Domestic livestock in Africa are of importance not only as a source of milk and meat but also as a source of animal traction enabling farmers to cultivate larger areas, with crops providing the staple foods. Trypanosomosis, a parasitic disease transmitted cyclically by the tsetse fly (Glossina spp.), is arguably still the main constraint to livestock production on the continent, preventing full use of the land to feed the rapidly increasing human population. Sleeping sickness, the disease caused in humans by species of Trypanosoma, is an important and neglected disease posing a threat to millions of people in tsetse-infested areas. Often wrongly thought of as a disease of the past, the prevalence of human sleeping sickness is increasing in many areas.Although alternative methods to control the disease are being investigated, such as immunological approaches, use of chemotherapy or exploitation of the trypanotolerance trait, it is only control or eradication of the tsetse fly vector which will remove the threat of the disease rather than providing a better means of ‘living’ with it. As a result of the economic impact of tsetse-transmitted Trypanosomosis, a large amount of research literature has been produced. This book provides a comprehensive review of this literature. The text is divided into four parts: tsetse biology and ecology, epidemiology, vector control and control of trypanosomosis. The book is invaluable for medical and veterinary entomologists, parasitologists and epidemiologists.
