Chalcidoidea Of Iran

The superfamily Chalcidoidea (Insecta, Hymenoptera) contains in excess of 26,000 described species worldwide, but with an estimated total diversity of more than 500,000 species the vast majority of species have yet to be discovered and described. Most chalcidoid species are parasitoids of hosts in at least 12 different insect orders, attacking the egg, larval or pupal stages, though phytophagy and other life cycles and hosts are known. Iran is the 18th largest country in the world and has a rich and diverse insect fauna, including Chalcidoidea. It is extremely interesting from a biogeographic point of view, and a paradise for an entomologist. This book summarizes the results of all prior research concerning species diversity of Iranian Chalcidoidea, including host records and distribution records by province in Iran as well as world distribution by country for 1,351 species of Chalcidoidea recorded from Iran through the end of 2019.

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.

Parasitoid wasps are cosmopolitan, numerous and enormously diverse with probably one million or more species worldwide, most of which occur in the moist tropics. Their ecological importance is enormous although perhaps most evident in their major roles in the control of insect pest populations. In natural ecosystems they are integral in regulating populations of a vast number of insects, and therefore are key players in terrestrial food webs. Knowledge of their biology is still very poor because the current state of taxonomy is still in its infancy in most parts of the world.In this book, we provide an overview of the more than 30 families of parasitoid wasps that occur in the 11 countries in South East Asia. Particular emphasis is given to those most commonly encountered and reared, as well as to those used in biological control programmes. Outlines of the morphology, biology, ecology and behaviour of each family, as well as of various important subfamilies are presented. The current state of taxonomy in the region is summarised. Other chapters cover basic biology, behaviour, morphological terminology, phylogeny and methods of specimen collecting, preparation and rearing with particular relevance to the tropics. Modern molecular approaches to speeding taxonomic description of hyperdiverse taxa are considered in depth. All groups are illustrated with colour photographs. This book will be of value to professional entomologists, academics, entomology students and the growing body of amateur entomologists and insect photographers.

Pests cause economic damage to crops and stored products, while vectors are responsible for the transmission of disease-causing agents in human beings and livestock. Although the application of synthetic pesticides in agriculture has given immediate relief, it has also caused well-known side effects, leading to a general consensus among entomologists and agriculturists to shift towards other ecofriendly pest management. Insect natural enemies consisting of predators, parasitoids, and pathogens have attracted the attention of scientists across the globe. These natural enemies exist in agroecosystems and suppress the populations of pests. Parasitoids are farmers’ friends and the most successful group of natural enemies. Highly specialised in their host choice, the female parasitoid searches for a suitable host to lay eggs and larvae in, on or near the hosts. Exploiting this potency of parasitoids may yield successful results in controlling notorious pests in an ecofriendly way. This book covers information on the important biocontrol agents effective in pest suppression. It starts with insect parasitic groups followed by specific groups of parasitoids. It is hoped that the book presents a comprehensive account of beneficial parasitoirds, and will be useful to undergraduate and postgraduate students of Entomology, Biological Control, Plant Protection, Agricultural Zoology, and Zoology, besides those involved in competitive examinations and policy planning. Features: Each chapter has been written by very experienced specialists Every chapter includes Learning Objectives and Points to Remember This book offers comprehensive knowledge of parasitoids and their application in pest management in a rational way

Caterpillars are excellent model organisms for understanding how multiple selective forces shape the ecology and evolution of insects, and organisms in general. Recent research using the tools of modern molecular biology, genetics, metabolomics, microbial ecology, experiments conducted at a global level, network analysis, and statistical analyses of global data sets, combined with basic natural history, are yielding exciting new insights into caterpillar adaptations and ecology. The best way to view these research advances is within a framework of tri-trophic interactions. This is a timely topic for research given the central role of caterpillars and plants in the ecology and trophic structure of terrestrial communities. This book is unique in that it contains chapters from a team of experts on a diversity of key topics within caterpillar-plant interactions. This volume brings together contributions by researchers from around the globe, working in both tropical and temperate habitats, and in human-managed and more natural habitats. It is a significant contribution to our understanding of insect biology, and the role that insects, as represented by caterpillars, play in a world increasingly dominated by humans and one in which threats to insect biodiversity are mounting.

Ice Caves synthesizes the latest research on ice caves from around the world, bringing to light important information that was heretofore buried in various reports, journals, and archives largely outside the public view. Ice caves have become an increasingly important target for the scientific community in the past decade, as the paleoclimatic information they host offers invaluable information about both present-day and past climate conditions. Ice caves are caves that host perennial ice accumulations and are the least studied members of the cryosphere. They occur in places where peculiar cave morphology and climatic conditions combine to allow for ice to form and persist in otherwise adverse parts of the planet. The book is an informative reference for scientists interested in ice cave studies, climate scientists, geographers, glaciologists, microbiologists, and permafrost and karst scientists. Covers various aspects of ice occurrence in caves, including cave climate, ice genesis and dynamics, and cave fauna Features an overview of the paleoclimatic significance of ice caves Includes over 100 color images of ice caves around the world
