Book Description
This publication is the result of a course on identification of Hymenoptera given three times since 1985 at the Centre for Land and Biological Resources Research. The considerable interest in these courses indicated the need for a comprehensive identification guide to all extant families of Hymenoptera. The main emphasis is on family identification using the keys, which are complemented by family sketches. The sketches include a taxonomic diagnosis to supplement the keys, a summary of the biology, the size and distribution, and important literature references.

Book Description
The book provides a reference to biological control of arthropod pests in agriculture and of public health importance in Iran. A quick glance over the literature shows a long history of biocontrol attempts in the country. Some historically important events highlighting the interest of Iranian academic, research and extension fields to the natural enemies and their applied aspects are provided. Iran, with an exception of the former USSR, was a pioneer in both basic and applied biocontrol in West Asia. The book consists of four parts: three parts for predators, parasitoids and pathogens, and last part for other approaches and analyses of the current state of biological control in Iran. The book provides the most up-to-date information on pest control and related topics of entomology in Iran. The chapters are written by scholars from major Universities and research centers in Iran.

Book Description
The Monteverde Cloud Forest Reserve has captured the worldwide attention of biologists, conservationists, and ecologists and has been the setting for extensive investigation over the past 30 years. Roughly 40,000 ecotourists visit the Cloud Forest each year, and it is often considered the archetypal high-altitude rain forest.This volume brings together some of the most prominent researchers of the region to provide a broad introduction to the biology of the Monteverde, and cloud forests in general. Collecting and synthesizing vital information about the ecosystem and its biota, the book also examines the positive and negative effects of human activity on both the forest and the surrounding communities. Ecologists, tropical biologists, and natural historians will find this volume an indispensable resource, as will all those who are fascinated by the magnificent wonders of the tropical forests.

Book Description
The rapidly growing human population has increased the dependence on fossil fuel-based agrochemicals, such as fertilizers and pesticides, to produce the required agricultural and forestry products. This has exerted great pressure on non-renewable fossil fuel resources, which cannot last indefinitely. Not only do agrochemicals pollute the environment, but pests also become resistant to pesticides. Thus, present agricultural practices exploit natural resources, and damage fauna and flora and agroecosystems. One safe alternative to overcome these problems is the use of allelopathy to sustain development in agriculture and forestry and maintain a clean environment for future generations. This book is the Proceedings of the III International Congress on Allelopathy in Ecological Agriculture and Forestry, held on August 18-21, 1998, at the University of Agricultural Sciences, Dharwad, Karnataka, India, and provides an updated status of current allelopathy research in various leading countries, with the overall aim of developing new technologies for ecological agriculture and forestry in the 21st century. To date, no book on ecological agriculture has discussed these aspects, hence it is the first time that such information is available. The chapter contributors are leading specialists in their fields, and all chapters have been peer-reviewed by international referees. This book will be indispensable for agricultural scientists (agronomists, entomologists, nematologists, plant pathologists, horticulturists, plant breeders, agroforesters, foresters, soil scientists), bioscientists (biochemists, organic chemists, plant ecologists, microbiologists and limnologists), environmentalists, graduate students and farmers, as well as for organizations engaged in sustainable agriculture and organic agriculture.
