Book Description
The multitrophic level approach to ecology addresses the complexity of food webs much more realistically than the traditional focus on simple systems and interactions. Only in the last few decades have ecologists become interested in the nature of more complex systems including tritrophic interactions between plants, herbivores and natural enemies. Plants may directly influence the behaviour of their herbivores' natural enemies, ecological interactions between two species are often indirectly mediated by a third species, landscape structure directly affects local tritrophic interactions and below-ground food webs are vital to above-ground organisms. The relative importance of top-down effects (control by predators) and bottom-up effects (control by resources) must also be determined. These interactions are explored in this exciting volume by expert researchers from a variety of ecological fields. This book provides a much-needed synthesis of multitrophic level interactions and serves as a guide for future research for ecologists of all descriptions.

Book Description
Combining breadth of coverage with detail, this logical and cohesive introduction to insect ecology couples concepts with a broad range of examples and practical applications. It explores cutting-edge topics in the field, drawing on and highlighting the links between theory and the latest empirical studies. The sections are structured around a series of key topics, including behavioral ecology; species interactions; population ecology; food webs, communities and ecosystems; and broad patterns in nature. Chapters progress logically from the small scale to the large; from individual species through to species interactions, populations and communities. Application sections at the end of each chapter outline the practicality of ecological concepts and show how ecological information and concepts can be useful in agriculture, horticulture and forestry. Each chapter ends with a summary, providing a brief recap, followed by a set of questions and discussion topics designed to encourage independent and creative thinking.

Book Description
This volume explores modern concepts of trophic and guild interactions among natural enemies in natural and agricultural ecosystems - a field that has become a hot topic in ecology and biological control over the past decade. It is the first book on trophic and guild interactions to make the link to biological control, and is compiled by internationally recognized scientists who have combined their expertise.

Book Description
Within a carnivore's lifecycle, there is often at least one stage that relies on plant-provided food, e.g., nectar. In fact, carnivore omnivory is far more common than first thought. Contributed by an international team of experts, this book suggests, among other ideas, that presence, or lack of, plant-provided foods for carnivores could determine the success or failure of agricultural ecosystems using Integrated Pest Management systems relying on predators as biological control agents.

Book Description
This textbook provides the first overview of plant-animal interactions for twenty years focused on the needs of students and professors. It discusses a range of topics from the basic structures of plant-animal interactions to their evolutionary implications in producing and maintaining biodiversity. It also highlights innovative aspects of plant-animal interactions that can represent highly productive research avenues, making it a valuable resource for anyone interested in a future career in ecology. Written by leading experts, and employing a variety of didactic tools, the book is useful for students and teachers involved in advanced undergraduate and graduate courses addressing areas such as herbivory, trophic relationships, plant defense, pollination and biodiversity.

Book Description
Insect parasitoids are a fascinating group of animals in many respects. Perhaps the most fascinating point is that these insects, in the course of the evolutionary time, have developed an impressive way to use chemical compounds to dialogue with the different protagonists of their environment (i.e., conspecifics, their hosts and the plants on which their hosts are living). Unravelling the evolutionary meaning of such chemical communication networks can give new insights into the ecology of these insects and especially on how to improve their use for the control of noxious pests in biological control programmes. Chemical Ecology of Insect Parasitoids is a timely publication, with organised chapters to present the most important knowledge and discoveries that have taken place over the last decade, and their potential use in pest control strategy. Specific relevant case studies are presented to enhance the reader's experience. Suited to graduate students and professional researchers and practitioners in pest management, entomology, evolutionary biology, behavioural ecology, and chemical ecology, this book is essential for anyone needing information on this important group of insects.

Book Description
The use of microbial plant protection products is growing and their importance will strongly increase due to political and public pressure. World population is growing and the amount of food needed by 2050 will be double of what is produced now whereas the area of agricultural land is decreasing. We must increase crop yield in a sustainable way. Chemical plant growth promoters must be replaced by microbiological products. Also here, the use of microbial products is growing and their importance will strongly increase. A growing area of agricultural land is salinated. Global warming will increase this process. Plants growth is inhibited by salt or even made impossible and farmers tend to disuse the most salinated lands. Microbes have been very successfully used to alleviate salt stress of plants. Chemical pollution of land can make plant growth difficult and crops grown are often polluted and not suitable for consumption. Microbes have been used to degrade these chemical pollutants.
