Fourteen informative papers dealing with their DNA, species interactions, adventiveness, host specificity, potential as boi-contol agents of weeds, chemical control, behaviour, their role in fungal pathogen epidemiology, influence in forests and on ornamentals, collecting and mounting techniques and their interaction with crops are presented here. This is an extensive and valuable contribution to eriophyoid science and a must for present and future researchers in this field.

Introduction to the acari, Population ecology, History of chemical control and mite resistance, Principles of chemical control of plant-feeding mites, Biological enemies of mites, Mites and plant diseases, The tetranychidae donnadieu, Injurious tetranychid mites, The eriophyoidea nalepa, Injurious eriophyoid mites.

Citrus pests are a serious issue for crop growers, causing problems in yield and economic losses. This title studies mites harmful to citrus plants from various citrus growing regions around the world. It addresses methods of removal from plants, describes symptoms of damage caused by pests and discusses methods of eradication and control.

This book is a timely compilation of synthesized information on behaviourally fascinating and economically important mites.The book gives much attention to fundamental aspects of eriophyoid anatomy, behaviour, ecology and even systematics, as bases for understanding the ways of life of eriophyoid mites and their effects on host plants; in turn, this will lead to developing the most appropriate means of regulating mites as detrimental or beneficial organisms. It presents new views intended to stimulate interest in eriophyoids and their enemies, and it points to areas where further research is needed. This book is intended for extension workers, experts of acarology and plant protection as well as students, teachers and researchers. It stimulates readers to critically test the view presented and aimes ultimately toward environmentally safe, sustainable and economically efficient means of regulating detrimental and beneficial eriophyoid mites.
