Book Description
Plant based biotechnology has come to represent a means of mitigating the problems of global food security in the twenty-first century. Products and processes in agriculture are increasingly becoming linked to science and cutting edge technology, to enable the engineering of what are in effect, designer plants. One of the most successful , non-chemical approaches to pest management and disease control is biological control, which seeks a solution in terms of using living organisms to regulate the incidence of pests and pathogens, providing a natural control' while still maintaining the biological balance with the ecosystem. This volume, (the first of two), addresses the different types of biocontrol for different pests, namely, crop diseases, weeds and nematodes, and details the biology of both the pest and its enemies, which is vital for efficient use of biological control. The book has numerous contributors who are authorities in their fields, and would be an asset to those who have interest in sustainable agriculture and crop productivity.

Book Description
Parasitic wasps represent an extraordinarily diverse group, with over 600,000 species having been described and perhaps a million or more species in existence today. If abundance equates with success, then these wasps rival the beetles in terms of animal dominance. Surprisingly, not until recently have these parasitic wasps received the attention due to them. This is not to say that the Parasitica division of the order Hymenoptera has been ignored. In fact, parasitic wasps have been the subjects of research investigations for nearly a century. However, unique facets of the biology of these parasitoids were largely unknown until the intensity of research using them as test subjects was heightened due to changes in pest control strategies in the United States and Europe. Increasing interest in integrated approaches to pest control within sustainable agricultural management programs led to studies on the basic biology of these wasps, and shed light on many aspects of their fascinating, and frequently beneficial, activities and biological features. The result has been a near revolution in terms of our understanding of natural history, biology and host-parasite interactions. Among the most dramatic areas of advancement have come in host-parasitoid maintenance and population dynamics. In particular, parasitic wasps were found to be capable of regulating their hosts, through manipulation of host behavior, physiology, and development for the benefit of developing wasp progeny. Hints of such host regulation can be found within previous literature, but it is only within the last two decades that many of the details of how the host is altered and what regulatory substances are involved have been deciphered. This paved the way for showing the role of many maternally derived secretions (e.g., polydnaviruses, calyx and ovarian fluids, virus-like particles, entomopoxvirus, and venoms), and in some cases larval fluids, in addition to the action of proteinacious venoms, either alone or synergistically, by female wasps to condition the host. Thus, these venoms are important sources of regulatory substances that are key to the success of the parasitoid using the host. Exceptionally noteworthy are the exciting array of changes in host condition that are elicited by sublethal doses of venom and its components, prompting new investigations into the utility of these bioactive compounds. Venoms from endo- and ectoparasitic wasp species exhibit various physiological and developmental effects, ranging from paralysis to molt inhibition to behavior modification, that vary depending on the host species and developmental stage attacked. Some wasps possess venom that permanently paralyze or kill the host, whereas others arrest or slow growth and development. Recently, parasitioid venom has been shown to have antimicrobial properties, and in other species, venom leads to conditioning the host for the purpose of over-wintering. These observations were largely unknown 20 years ago when Tom Piek edited his excellent treatise Venoms of the Hymenoptera (1986), and likewise, only a small portion of Donald Quicke s outstanding book Parasitic Wasps (1997) could be devoted to the subject of venoms of parasitic wasps. So few outside of the field of parasitic wasp venoms have delighted in the complexity of venom cocktails, modes of action, or physiological effects. Here, we have enlisted the help of several researchers to share their insight into the biochemistry of venoms from endo- and ectoparasitic wasp species; the modes of action these venoms and effects on insects hosts at the organismal, tissue and cellular level; and the relevant toxicity of venoms or isolated toxins toward host and pest insects. Our hope is that this book provides a comprehensive coverage of some of the most current work being conducted throughout the world on parasitic wasp venoms. Ultimately, though, our desire is to foster discussion and encourage further research with these fascinating creatures, whether for biological control purposes or out of sheer intellectual curiosity.

Book Description
There are more than 36,000 described species in the family Cerambycidae in the world. With the significant increase of international trade in the recent decades, many cerambycid species have become major plant pests outside their natural distribution range, causing serious environmental problems at great cost. Cerambycid pests of field, vine, and tree crops and of forest and urban trees cost billions of dollars in production losses, damage to landscapes, and management expenditures worldwide. Cerambycidae of the World: Biology and Pest Management is the first comprehensive text dealing with all aspects of cerambycid beetles in a global context. It presents our current knowledge on the biology, classification, ecology, plant disease transmission, and biological, cultural, and chemical control tactics including biosecurity measures from across the world. Written by a team of global experts, this book provides an entrance to the scientific literature on Cerambycidae for scientists in research institutions, primary industries, and universities, and will serve as an essential reference for agricultural and quarantine professionals in governmental departments throughout the world.

Book Description
Increasing attention has been focused on biodiversity in recent years, based on a number of arguments to justify the conservation of the world's flora and fauna. Such arguments may be economic - that species may have potential for food or medicine - or ecological - that the extinction of any species affects the overall ecological balance. Little attention, however, has been focused on which groups have the greatest impact on maintaining diversity. Hymenoptera is one of these groups. It not only forms a major component of diversity itself, but is vital in sustaining diversity in other groups. Hymenoptera species (bees, wasps, ants and sawflies) are major plant pollinators, seed dispersers and parasitoids and predators of other arthropods (and hence important in biological control). This volume therefore tackles an important subject and concentrates on three key issues: how species of Hymenoptera affect diversity in other organisms; whether Hymenoptera is a group prone to extinction; and the consequences if Hymenoptera species are differentially removed from terrestrial ecosystems. The book is essential reading for entomologists and those concerned with biodiversity and conservation.

Book Description
This issue celebrates the 75th birthday ofÿ Dr. Lubom?r Masner, a source of knowledge, enthusiasm, and inspiration for systematic entomologists in all fields, but especially for students of Hymenoptera. His unflagging dedication to the study of the parasitoid wasps of the superfamilies Proctotrupoidea, Platygastroidea, and Ceraphronoidea has completely transformed our understanding of the richness and evolutionaryÿ history of these insects. His zeal and innovation in collecting have not only dramatically enhanced the basis for our understanding of hymenopteran diversity, but also contributed to the development of the Canadian National Collection of Insects into one of the premiere systematic entomology research institutions in the world. Twenty-six authors have contributed to this volume in 17 papers on the systematics of the families Braconidae, Ceraphronidae, Chalcididae, Eucharitidae, Eupelmidae, Eurytomidae, Figitidae, Mymaridae, Platygastridae, Vespidae, and Xiphydriidae. Six new genera and 33 new species are described, encompassing fossil material as well as species from the Neotropical, Afrotropical, Oriental, and Australasian regions. A short biography of Dr. Masner is accompanied by a bibliography of his scientific papers, a list of taxa he has described over 55 years of research, and a list of taxa named in his honor.
