For large-scale agroecosystems, patterns of pest population increases (graded increases or abrupt outbreaks) and declines (graded suppression or abrupt crashes) vary considerably and are influenced by factors within crop fields and across broader landscape scales. Better understanding of pest population dynamics and the implications of spatial interactions on the function and development of pest management approaches are the main themes of this important book. The book builds from a 60+ year history of field-based pest management by focusing on the drivers of pest management in large-scale agroecosystems and the landscape-scale processes that affect these drivers and contribute to variation in pest outbreaks and suppression. These drivers include abiotic and biotic influences such as weather, spatial composition and arrangement of landscape elements, and widely applied managed inputs such as planting and crop rotation schedules, crop varietal selection, and land and soil conservation efforts. The book introduces general concepts, opportunities, and challenges of arthropod management in large-scale agroecosystems. Case studies from major field crop-based agroecosystems are used to present research approaches and improve understanding and management of pest and beneficial insects in large-scale agroecosystems. Specific research findings are provided on multi-trophic interactions within the system as influenced by climate, landscape, and other ecological, agricultural, and social/economic components of the agroecosystem. The book concludes with a synthesis of these concepts and prospectus for future research and developments in arthropod management in large-scale, plant-based agroecosystems. The book is essential reading for researchers in applied entomology and ecology and for pest management practitioners.

This collection features four peer-reviewed literature reviews on mite pests in agriculture.The first chapter offers a holistic approach to integrated mite management by reviewing the basics of mite taxonomy and morphology. It studies the key plant mite families, focussing on major plant feeding mites (Tetranychidae, Tarsonemidae, Eriophyoidea), as well as the natural predators that regulate these mite populations.The second chapter explores the cultural, biological and chemical control tactics available for controlling major plant feeding mites. These tactics include: choosing tolerant varieties and weed management. The chapter concludes with a discussion on the debate surrounding the best form of control for mite pests in agriculture.The third chapter highlights the importance of understanding the bio-ecology of Tetranychidae species affecting tomato crops, including the two-spotted spider mite, carmine spider mite and red spider mite. The chapter considers the effects of each pest on tomato plants, as well as how best to control them.The final chapter details the ecology of mite pests affecting wheat that belong to the Eriophyoidea family, such as gall mites and wheat curl mites. The chapter discusses the various forms of control for managing Eriophyid mites, as well as the development of new resistant varieties of wheat.
