Microbial responses to acidic and alkaline pH are important in many areas of bacteriology. For example, the mechanisms of resistance to acidic pH are important in the understanding of the passage of human pathogens through the acid of the stomach; and an understanding of microbial degradation of alkaline industrial waste is important for the environment. Bringing together contributions from an international and interdisciplinary group of experts working on the many aspects of bacterial cellular responses to pH, this stimulating volume draws together new and innovative work in this area. It delineates both similarities and differences between mechanisms of tolerance and response, providing readers with an invaluable resource on the subject.

Exotic pests and diseases have long been an important concern in agriculture. The problem is becoming increasingly urgent and complex because agricultural trade has been liberalized worldwide, and as a consequence, the probability of spreading a disease or a pest through national borders has become a real threat, not only for the agricultural industry but also for human health and the natural environment. This edited volume’s list of international contributors reads like a Who’s Who of international agricultural research! This book includes ten interdisciplinary case studies that focus on specific pests or diseases that represent a range of threats to U.S. agriculture, wild lands and the urban landscape, and possible government responses to these threats. Each chapter combines, in an original fashion, biological foundations and implications for the public, giving powerful insights to a series of public policy issues of national and international relevance. In many instances, economic analysis of alternative policies is included. Exotic pest control is discussed in a public good general framework, and under the international regulatory laws comprised by the Sanitary and Phytosanitary Protocol of the WTO.

Biological control – utilizing a population of natural enemies to seasonally or permanently suppress pests – is not a new concept. The cottony cushion scale, which nearly destroyed the citrus industry of California, was controlled by an introduced predatory insect in the 1880s. Accelerated invasions by insects and spread of weedy non-native plants in the last century have increased the need for the use of biological control. Use of carefully chosen natural enemies has become a major tool for the protection of natural ecosystems, biodiversity and agricultural and urban environments. This book offers a multifaceted yet integrated discussion on two major applications of biological control: permanent control of invasive insects and plants at the landscape level and temporary suppression of both native and exotic pests in farms, tree plantations, and greenhouses. Written by leading international experts in the field, the text discusses control of invasive species and the role of natural enemies in pest management. This book is essential reading for courses on Invasive Species, Pest Management, and Crop Protection. It is an invaluable reference book for biocontrol professionals, restorationists, agriculturalists, and wildlife biologists.

Oilseed rape, a major crop in many parts of the world, is attacked by a wide range of insect pests, many of which are of considerable economic importance. With the increasing demand to reduce agrochemical inputs on arable crops, the Commission of the European Communities supported a three-year programme in which scientific participants reviewed the natural enemies of oilseed rape insect pests. The various outputs from this important work form the basis of this comprehensive new book. Biocontrol of Oilseed Rape Pests commences with a review of the oilseed rape crop, followed by chapters on pests, pest management strategies and parasitoids of specific pests or groups of pests. Detailed information is also included on sampling, trapping and rearing pests, their parasitoids and predators; the identification of hymenopterous parasitoids; pathogens of oilseed rape pests, predators, predator taxonomy and identification, and the impact of on-farm landscape structures and systems on predators. This book is an essential purchase for all those involved with oilseed rape and for anyone with an interest in agricultural biocontrol strategies. It is also essential reading and an invaluable source of reference for agricultural scientists, entomologists, crop protection specialists, advisers and consultants. All agrochemical companies should have multiple copies of this book on their shelves, as should all libraries in universities and research establishments where biological and agricultural sciences are studied and taught. Dr David V. Alford, based in Cambridge, UK, has many years of experience working as a government entomologist.
