vi The intent, therefore, was to provide for a fresh and original review of all relevant topics and issues in the field, following a comprehensive and coherent programme. Such an ambitious goal could only be reached thanks to the unlimited collaboration of the lecturers: They were requested to produce nothing less than "freer, broader, speculative and personal "considerations of the subjects" they had to cover ••• And so they did: their presentations unfolded a fantastic picture, a most fascinating and meaningful identification of the field, its present problems and trends. But participants at this conference contributed many valuable observations while discussing specific points. Unfortunately, more often than not, it proved impossible to identify them in the records. Accordingly, we incorporated here and there some of these "anonymous" contributions as part of the edited version of the texts. To all of the participants, I would like to express my gratitude for their actively taking part in all the scientific (and social ••• ) activities (lectures, round tables, posters, encounters) of this N.A.T.O. ASl. The result was a stimulating atmosphere, conducive to authentic scientific exchanges. Hence, the success of this meeting should be credited only to them. Finally, on behalf of all participants, I would like to thank Professor Sissini, the Mayor of Maratea, and Mr. B. Vitolo, the Chairman of its Tourist Office: their enthusiastic support greatly contributed to make of our time in their wonderful seaside resort an unforgettable one.

There are over a million different species of insects, and individually they 8 outnumber humans by more than 10 to 1. Moreover, some insects live in close association with both plants and higher animals and naturally exchange viruses with them. It has even been speculated that viruses in general may have radiated through the plant and animal kingdoms from common insect origins. Be that as it may, since insects play pivotal roles in the biosphere, both to the benefit and detriment of mankind, they and the viruses that infect them are important subjects for study. Insects are infected by a diverse medley of viruses, and this volume focuses on those insect virus families that are found primarily or exclusively in insects. All major families of insect-selective viruses are covered except for the baculo viruses, which were described in a separate volume of The Viruses series. Included in this volume are the established families of insect viruses, the newly recognized ascovirus family, and the nudiviruses, which probably represent a separate family but currently remain unclassified. The coverage of arboviruses is limited to a single chapter that focuses on their potential utility as vectors and in insect control. Omitted for practical reasons are several individual insect viruses that have been described sporadically in the literature and probably represent novel virus families.

A springboard for developing new approaches to understanding, preventing, and treating picornaviral diseases. • Examines the most current breakthroughs as well as the challenges that lie ahead in picornavirus research; encapsulates current knowledge of the molecular biology, evolution, and pathogenesis of this large family of viruses; and, examines the diseases that these viruses cause and the latest vaccines and antiviral drugs to prevent and control those diseases. • Explores the structural and mechanistic bases of picornavirus replication, highlighting new insights about the host cell interactions needed for virus growth; and, illustrates how the regular occurrence of mutations, typical of viruses with RNA as genetic material, generates the quasispecies dynamics that underlie viral fitness. • Focuses on picornaviruses that cause disease, examining pathogenicity and innate and acquired immune responses against infection as well as the latest vaccine and antiviral drug strategies.

The pathology caused by baculoviruses in insect popula­ tions was described centuries ago, notably in the larvae of insects such as the silkworm (Bombyx mori) which has been appreciated for the quality and beauty of its products. In the 1940s baculoviruses and their structure and physiolo­ gy were intensively investigated, particularly by Bergold's group in Tiibingen. The following decades saw excellent progress, laying a solid virological base for later investiga­ tions on the system. Further studies mushroomed in the 1970s with the advent of tissue culture systems for insect cells which eventually facilitated the molecular biological approach that came to the fore in the 1980 s. One of the reasons for pursuing research on the baculo­ virus system was the prospect of eventually using these vi­ ruses as insect pest control agents. While this practical as­ pect may appeal to many, molecular biologists had addi­ tional reasons to be interested in baculoviruses. Here was a large DNA viral genome, probably fraught with problems of replication and regulation that hopefully would open inroads into the molecular biology of interesting insect cell systems. In the days when genetechnology promises laurels, and after several virus systems had been skilfully exploited as highly efficient eukaryotic expression vectors, it came as no surprise that baculoviruses were also investigated in that respect. Indeed, the Autographa californica nuclear po­ lyhedrosis virus became a good vector. Insect cells also seem to collaborate in modifying and processing the gene­ technologically synthesized polypeptides.

Viruses that are pathogenic to beneficial insects and other arthropods cause millions of dollars of damage every year to industries, such as sericulture, apiculture, and aquaculture (e.g. infecting honeybees and silk worms). On the other hand, viruses that are pathogenic to insect pests can be exploited as attractive biological control agents. Another fascinating feature of these viruses is that some, e.g. baculoviruses, have been commercially exploited for use as gene expression and delivery vectors in both insect and mammalian cells. All of these factors have led to an explosion in the amount of research into insect viruses in recent years, generating impressive quantities of information on the molecular and cellular biology of these viruses. This timely book reviews the exciting new developments in the field of insect virology. Written by internationally renowned insect virologists, the chapters review the current molecular biology of all the major groups of insect pathogenic viruses and suggest future directions for research. The book is divided into three parts: 1) DNA viruses, 2) RNA viruses, and 3) current hot-topics in insect virology. The virus groups covered include: Ascoviruses, Baculoviruses, Densoviruses, Entomopoxviruses, Hytrosaviruses, Iridoviruses, Nudiviruses, Polydnaviruses, Dicistroviruses, Iflaviruses, Nodaviruses, Tetraviruses, and Cypoviruses. Special topic chapters review exciting recent developments in insect virology including RNAi, insect antiviral responses, structural comparison of insect RNA viruses, and viral ecology. The book is essential reading for every insect virologist in both the academic and private sectors. It is also strongly recommended for other virologists, particularly those interested in virus evolution, virus structure, viral vectors, biological control of insects, and insect immunity.
