The history of biological control of harmful organisms by mites is marked by outstanding achievements with a few premiere natural enemies. Early works concentrated on the use of predatory mites for the control of synanthropic flies, More recently, the focus has been mostly on mites of the family Phytoseiidae for the control of plant feeding mites. This is an important family of acarine predators of plant pest mites, which are effectively used in agriculture worldwide. Besides the vast knowledge in several species in this family, there are as well many opportunities for biological control, represented in an array of organisms and through the improvement of management techniques, which are constantly explored by researchers worldwide. This has resulted in an increasing interest in predatory mite species within the families Stigmaeidae, Ascidae, Laelapidae, Rhodacaroidea, Macrochelidae, Erythraeidae and Cheyletidae, among others. This book will compile important developments with predatory mite species within these families, which are emerging as important tools for integrated pest management. New developments with predatory insects and pathogenic organisms attacking mites will also be a subject of this book. Finally, the potential and gaps in knowledge in biological control of acarine plant pests will be addressed.

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.

Guava (Psidium guajava L.) is an exquisite, nutritionally and economically valuable crop of tropical and subtropical regions of the world. It outshines other tropical fruits in productivity, hardiness, adaptability, nutritional value, and ensures higher economic returns to growers. Guava is commercially grown in over 70 countries, and is gaining in popularity as a 'super fruit' due to its nutritional and health benefits. Notable recent developments include the potential to improve crop yields and quality. New research has also contributed to better understanding of the crop environment, plant growth and physiology of tree and fruit development, with implications for both breeding and cultivation. Guava is one of the few tree fruits where round-the-year harvest is possible by crop regulation. Interspecific hybridization with wild Psidium species has yielded hybrids which are resistant to wilt (a major guava disease in many countries) and are graft compatible. This book: * is the only publication available in English covering sustainable guava cultivation; * presents the current state of knowledge on the origin, history, physiology, culture and trade of guava throughout the world; and * addresses the major production and post-harvest problems. With contributions from international experts, this is a valuable resource for researchers and students in horticulture, and guava-industry support personnel.
