The Phytoseiidae are among the best-known mite families, with more than 2,700 recorded species worldwide. Some of those phytoseiids are used as biocontrol agents to fight agricultural pests. But in order to study their potential, it has become urgent to first establish a reliable taxonomy of Phytoseiidae. This book presents a general review of the classification and external morphology of the family Phytoseiidae in Taiwan and neighboring islands. Between 2009 and 2019, more than 20,000 specimens were gathered over the course of 2,500 collections. This book focuses on 64 species belonging to three subfamilies and fourteen genera, among which are five novel species and eight newly-recorded species; it provides their descriptions and illustrations, as well as information on their habitat plants and food habits. 植綏蟎科（捕植蟎）是最有名的蟎類之一，全世界已經紀錄了超過 2,700 種，部分種類是小型農業害蟎（蟲）的天敵。然而為了研究其生物防治潛力，可靠的分類研究即成為急迫要進行的事。本書提供一針對臺灣產植綏蟎科完整的分類研究與其外部形態的回顧，自 2009 年至 2019 年，調查超過 2,500 筆採集紀錄，20,000 筆標本。本書包含了植綏蟎科，3亞科、14 屬、64 種，並包含先前已發表的 5 新種與 8 新紀錄種；針對所有物種提供完整重新描述與繪圖，並提供其棲息植物與其食性。

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.

Mites and ticks are everywhere and acarologists go after them – some explore their bewildering diversity, others try to understand their how and why. For the past 50 years, the International Congress of Acarology has been the forum for worldwide communication on the knowledge of Acari, helping researchers and students to look beyond their disciplines. Many mites and ticks are economic factors as they are pests of agricultural, veterinary and medical importance, and several species have become model organisms in modern biology. The 96 contributions to Trends in Acarology – reflecting fields as molecular biology, biochemistry, physiology, microbiology, pathology, ecology, evolutionary biology, systematic biology, soil biology, plant protection, pest control and epidemiology – have been reviewed and carefully edited. This volume contains a wealth of new information, that may stimulate research for many years to come.

Mites (Acari) for Pest Control is an extremely comprehensivepublication, covering in depth the 34 acarine families that containmites useful for the control of pest mites and insects, nematodesand weeds. In addition to providing information on each relevantacarine family, the book includes essential information on theintroduction, culture and establishment of acarine biocontrolagents, the effects of the host plants, agrochemicals andenvironmental factors on mites used in biological control anddiscusses commercial and economic considerations in theiruse. Mites are now used in various ways for biological control, witha growing number of species being sold commercially throughout theworld. The authors of this landmark publication, who have betweenthem a huge wealth of experience working with mites in biologicalcontrol programs, have put together a book that will for many yearsbe the standard reference on the subject. The book will be of great value to all those working in cropprotection and biological control both in research as well as incommercial operations, including acarologists, entomologists,integrated pest management specialists, agricultural and plantscientists. Libraries in all universities and researchestablishments where these subjects are studied and taught shouldall have copies on their shelves.

Reducing environmental hazard and human impact on different ecosystems, with special emphasis on rural landscapes is the main topic of different environmental policies designed in developed countries and needed in most developing countries. This book covers the bioindication approach of rural landscapes and man managed ecosystems including both urbanised and industrialised ones. The main techniques and taxa used for bioindication are considered in detail. Remediation and contamination is faced with diversity, abundance and dominance of biota, mostly invertebrates. Invertebrate Biodiversity as Bioindicators of Sustainable Landscapes provides a basic tool for students and scientists involved in landscape ecology and planning, environmental sciences, landscape remediation and pollution.

The words pronounced by Serge Kreiter during the meeting come to mind. They could record exactly the situation of Acarology in Europe and in the World: "I think that in many European countries there are very few full time acarologists. It is very rare to have new positions available . . . . And public money, from the European Community but also from national countries, is very hard to get when you want to work on mites . . . . Could two acarological associations in Europe (Eur. A. Ac. and S. I. A. L. F) work together or, better, get married?" So, the fourth symposium of the European Acarologists has not only been the occasion to have an idea on which direction the research is addressed today, but also it pointed out the difficulties of our "scientific hranch". On the basis of the presentations and invited papers we had evidences of a "new" Acarology based on modern techniques and methods of investigations but also the importance, often sheltered even if of relevant value, of the "old" Acarology made on the alpha taxonomy and basic studies. So, a "new" Acarology needs the "old" one. In this context, the hope to put together the European acarologists has been coming up. This fact, of political meaning, can surely improve the acarological movement and the discussion on this point showed clearly the importance of several other activities and efforts in this direction. We hope that the meeting in Siena will represent a significative stone for the progress of Acarology.
