Freshwaters of Alaska


Book Description

Alaska's great size is mirrored by the large number and diversity of its freshwater ecosystems. This volume reviews and synthesizes research on a variety of Alaskan freshwaters including lakes, rivers and wetlands. The vast range of Alaskan habitats ensures that the chapters in this book will provide valuable information for readers interested in freshwaters, particularly nutrient dynamics, biotic adaptations, recovery mechanisms of aquatic biota, stream succession and the management of human-induced changes in aquatic habitats.




Insect Pest Management


Book Description

This book explores ecologically sound and innovative techniques in insect pest management in field and protected crops. From a general overview of pest management to new biorational insecticides such as insect growth regulators, and new strategies to reduce resistance, the coverage is entirely up-to-date. Other chapters describe advances in pest management of important crops such as cotton, corn, oilseed rape and various vegetables.

Bemisia: Bionomics and Management of a Global Pest


Book Description

Bemisia tabaci (Gennedius) has distinguished itself from the more than 1,000 whitefly species in the world by its adaptability, persistence and potential to damage a wide range of agricultural and horticultural crops in all six of the world’s inhabited continents. B. tabaci inflicts plant damage through direct feeding, inducement of plant disorders, vectoring of plant viruses and excretion of honeydew. This book collates multiple aspects of the pest ranging from basic to applied science and molecular to landscape levels of investigation. Experts in multiple disciplines provide broad, but detailed summaries and discussion of taxonomy, genetics, anatomy, morphology, physiology, behavior, ecology, symbiotic relationships, virus vector associations and various tactics for integrated management of this pest insect. The book is focused primarily on progress during the last 10-15 years and is directed at workers in the field as well as the informed professional who may not necessarily specialize in whitefly research. The book is unique in providing broad coverage in relatively few chapters by recognized experts that highlight the state-of-the-art in our understanding of this fascinating but troublesome cosmopolitan pest.
















A Spatially Explicit Individual-based Model of the Population Dynamics of the Greenhouse Whitefly (Trialeurodes Vaporariorum), Encarsia Formosa and Tomato Powdery Mildew (Oidium Neolycopersici) in Tomato Crops


Book Description

The greenhouse whitefly Trialeurodes vaporariorum - Westwood is one of the most important insect pests in crops. The spatial dynamics and population grow of the insects are affected by different biotic and abiotic factors like the host plant quality, the control by natural enemies or the presence of another kind of pest such as mildew fungus. Patterns of the population behavior in tomato crops were used to develop an age-structured, spatially explicit, individual-based model with a description of the developmental biology of the whitefly individuals. The model comprises three types of entit...
