This book presents comprehensive information on various aspects of ecology with special reference to insects, to form a platform to design an ecologically sound insect pest management. Insects are the most dominant and diverse group of living organism on earth. Owing to their smaller size, smaller space and food requirements, more number of generation per unit time, insects serves as one of the best subject matter for studies on various ecological aspects such as chemical ecology, population dynamics, predator/parasitoid-prey interactions etc. The knowledge on various aspects of insect ecology helps in formulating an effective environmentally benign insect pest management. This book is of interest and use to the post graduate students and researchers working on various aspects of insect ecology with special emphasis on population dynamics, chemical ecology, tri tropic interactions, ecological engineering and Ecological Insect pest management.

This book provides the first monograph of Coccinellidae. Although the group finds inclusion both in Clausen's (1940) "Entomophagous Insects" and in Balduf's (1935) "Entomophagous Coleoptera", reference in these works is limited to three and twenty pages respectively. Moreover, the last thirty years since these books appeared have ~een a great deal of work on the group. The use of insecticides largely destroyed the early attempts at biological control and interest remained low for as long as insecticides appeared quite successfuL However, the problems of insecticides soon became apparent, and in the last decade there have been tremendous developments in biological control, particularly in eombin

Proceedings of the 2nd Symposium held at Zvikovske podhradi, September 2-8, 1984

This volume deals mainly with the biology of the American cockroach, Periplaneta americana (1.). Contributors were urged to emphasize recent findings, including unpublished data when possible, a goal that would not have been feasible if it were not for the two previously published books on the basic biology of cockroaches, The Biology o/the Cockroach (1968) by D. M. Guthrie and A. R. Tindall and The Cockroach, Volume 1 (1968) by P. B. Cornwell. Those topics not included in The American Cockroach, such as external morphology, are well covered in the two preceding books. In addition, these books provided a broad background upon which contributors to The American Cockroach have been able to build with recent trends, new and established concepts and integration. Although this book deals primarily with the American cockroach, many chapters offer a comparative approach in sections where the more recent and exciting research has been accomplished on other species. Most contributors place the cockroach in perspective with regard to its appropriateness or inappropriateness for various types of biological investigations. Many questions are realistically left unanswered when no acceptable or obvious solution is apparent; an invitation to new researchers to consider the cockroach as an experimental subject.

Few branches of the biological sciences have developed to such an extent as has ecology in the recent decades. The successful development of this science is directly related to need to create a sound scientific basis by which we can control our diminishing natural resources and integrate this with the control of biological systems of the component species. Studies on the bioenergetics of ecosystems, as well as on the home ostatic mechanisms functioning at the populations and biocenoses levels are of great importance in this respect. The results of these studies are very significant in forestry management which deals with multiannual tree communities - forest stands. It is particularly important in this of the necessity for the possible respect for economic planning, in view prolonged maintenance of forest biocenoses as stable systems. Neither in the present nor in the immediate future can be protection of forest ecosystems consisting of natural plant and animal communities be achieved by the cultivation of resistant forms or the intensification of chemical intervention."

Studies of insect nervous systems have made an immense contribution to our understanding of how a brain works and the way that the connections between constituent neurons are formed during development, For the first time these studies are brought together in The neurobiology of an insect brain, a personal account by a leading experimental neurobiologist and zoologist. By concentrating largely on one insect, the locust, this book unravels the mechanisms by which a brain integrates the vast array of sensory information to generate appropriate movements and behaviour. It first describes the basic structure of an insect brain and how this complex structure is formed during embryonic development. The cellular properties of the different types of neurons, and the way they are altered by neurosecretions are then analysed with respect to the integrative actions of these neurons during behaviour. Finally, the various movements that an insect performs are investigated at the cellular level to illustrate particular features of the integrative processing. Throughout, the book emphasises how knowledge of these simpler nervous systems contributes to our understanding of more complex brains, and at the same time provides the functional synthesis into which future molecular and computational studies can be woven. The neurobiology of an insect brain is an important milestone in our search for unifying principles of brain organisation and will be essential reading for students and research workers in neurobiology, behaviour, and entomology. our understanding

Lepidoptera and Coleoptera butterflies and beetles - are the most beautifully colored insects we can find. This book explores the origin of these brilliant colors from a physics perspective, beginning with the simplest question: Why Colors? The author masterfully explains at an introductory level the coloring of insects and illustrates his points with more than 240 brilliant figures. The book is a rich source for optical physicists, biologists, and teachers alike.

Echinoderms are now considered as a biological and geological model that underlies researches of primary importance. The extent of the contributions made by the International Echinoderm Conferences to various fields of research is attested by the scope covered by presentation at the international conferences. These proceedings contain the complete papers or abstracts of all the presentations and posters presented at the eighth International Echinoderm Conference, held in Dijon, France in September, 1994. Coverage includes: general; extinct classes; crinoids; asteroids; ophiuroids; holothuroids; and echinoids.

The 9th International Symposium on Insect-Plant Relationships (SIP-9) was once more, following the tradition established in 1958, a forum for investigators in both basic and applied entomology interested in the important and fascinating field of interactions between plants and insects. We were pleased and honoured to organise this symposium, which took place June 24--30, 1995 in Gwatt on the shores of the Lake of Thun in Switzerland. 168 participants from 26 countries from all over the world actively took part in the symposium by contributing 12 key-note lectures and a total of 141 oral presentations and posters. The favourable response and the lively interaction of the participants in all symposium activities is the clearest indication of the success of SIP-9. The organisers appreciated the enthusiasm and the willingness to collaborate shown by all participants. The following volume contains written contributions (72) of only half of all presentations. This is due to the fact that we decided to produce not only an account of the proceedings but also to publish all contributions as a special volume of the journal Entomologia Experimentalis et Applicata. This procedure was last adopted in 1978 for SIP-4, organised by Reginald F. Chapman and Elizabeth A. Bernays, and ensures a wide distribution of the papers within the scientific community and easy access through libraries. Inevitably we had to employ the same review procedure as applicable for the manuscripts regularly submitted to Entomologia.

Drosophila is a comprehensive collection of methods and protocols for Drosophila, one of the oldest and most commonly used model organisms in modern biology. The protocols are written by the scientists who invented the methods. The text presents a diverse set of techniques that range from the basic handling of flies to more complex applications. This is the perfect reference manual for Drosophila researchers.

Recent studies have shown that genetic polymorphisms play an important role in structuring the seasonal life cycles of insects, complementing an earlier emphasis on the effects of environmental factors. This book presents current ideas and recent research on insect life--cycle polymorphism in a series of carefully prepared chapters by international experts, covering the full breadth of the subject in order to give an up-to-date view of how life cycles are controlled and how they evolve. By consolidating our view of insect life--cycle polymorphism in this way, the book provides a staging point for further enquiries. The volume will be of interest to a wide variety of entomologists and other biologists interested in the control and evolution of life cycles and in understanding the extraordinarily complex ecological strategies of insects and other organisms.

Insects and plants, whether or not they coevolved, have intimate interrelationships. This book concisely yet thoroughly describes these phenomena. In one chapter the salient facts known about carnivorous plants are described. In another, ant and plant relationships are summarized as an introduction to this vast subject. Pollination, of great interest to agriculturists and horticulturists, is briefly explained without the complexities detailed in the massive literature on this topic. Many other subjects are discussed, such as the memory of adult butterflies, which enables them to return to their host plants in the case of the polyphagous species. The book is seeded with such thought-provoking discussions as prostitution among the orchids and botanical indigestion in some plants.

This book is devoted to the ichnology of insects, and associated trace fossils, in soils and paleosols. The traces described here, mostly nests and pupation chambers, include one of the most complex architectures produced by animals. Chapters explore the walls, shapes and fillings of trace fossils followed by their classifications and ichnotaxonomy. Detailed descriptions and interpretations for different groups of insects like bees, ants, termites, dung beetles and wasps are also provided. Chapters also highlight the the paleoenvironmental significance of insect trace fossils in paleosols for paleontological reconstructions, sedimentological interpretation, and ichnofabrics analysis. Readers will discover how insect trace fossils act as physical evidence for reconstructing the evolution of behavior, phylogenies, past geographical distributions, and to know how insects achieved some of the more complex architectures. The book will appeal to researchers and graduate students in ichnology, sedimentology, paleopedology, and entomology and readers interested in insect architecture.

This book is a collection of comprehensive and latest information on all aspects of vaccination in fish and shellfish. It provides the basic understanding about the immune system of both fish and crustaceans, besides giving the latest information on adjuvants, vaccine delivery methods, adverse effects of vaccines and methods to assess the efficacy of vaccines. Separate chapters on the role of pattern recognition receptors and interferons in fish vaccination, biofilm vaccines and biosafety and regulatory requirements for fish vaccines are also included. Aquaculture, being the fastest growing food producing industry in the world, is looked upon for alleviating the malnutrition especially among the under privileged population. However, intensive aquaculture practices have led to increased incidences of diseases and significant production losses. Among various health management measures employed in aquaculture, vaccination has been proven to be the best approach to protect fish against pathogens. It is considered to be safe and is a key factor for sustainable aquaculture. In this background, apart from the basic understanding of fish and shellfish immune system, updated knowledge on various types of vaccines and the vaccination strategies currently employed in aquaculture are also covered. The book is designed to provide the latest and comprehensive knowledge on all these aspects as a compiled resource material which is useful to students, researchers and other professionals in the field of aquaculture.

This work was begun to provide keys to the aquatic insect species known from Brazil. The original goal was to include all genera known from South America and all species from Brazil, but for most groups, the scope was expanded to encompass all species in South America, and, in some cases, to include terrestrial species of orders comprising both terrestrial and aquatic taxa. In no case is a taxonomic rev1s10n of any group undertaken, although recommendations for such revisions are included where appropriate, and probable synonymy of nominal species still treated as valid in the literature is noted. Two different approaches will be employed according to the taxon being treated. For phylogenetic groups encompassing overwhelmingly or exclusively aquatic species, such as the orders Plecoptera and Ephemeroptera or the families Dytiscidae and Culicidae, keys are provided to distinguish all genera and species known to occur in South America. An effort has been made to include every identifiable species so that the user of the key can determine with reasonable certainty whether or not his specimen belongs to a species that has already been described or whether it is one that is not yet known to science. Where feasible, complete keys will be prepared for groups containing both aquatic and terrestrial species that do not encompass an extraordinarily large number of species. This has already been done for the order Collembola.

Updated and much expanded, the Second Edition of Parasitic Protozoa is designed to be useful to physicians, veterinarians, and research scientists concerned with diseases caused by protozoa in man, and in domestic and wild animals including fish, mollusks and insects, as well as the more commonly considered vertebrate animals. Each section contains information on disease pathogens, treatment, diagnosis, and epidemiology of the diseases caused by the various protozoans. The book is not limited to these medically-oriented subjects, but treats taxonomy, morphology, and metabolism of the organisms in such a way as to be of interest to scientists and graduate students working in the field of protozoology. The entire edition, published in ten volumes, is arranged so that subjects of common interest occupy individual volumes.

This title discusses egg formation, release, and development, variations in life history patterns, population, and fisheries aspects regarding crustaceans.

Ecology and Morphology of Copepods is organized under the following general topics: Behavior, Feeding, Genetics, Horizontal Variations, Morphology, Phylogeny, Reproduction, Seasonal Changes, Vertical Distribution, plus two special sessions on copepods of the genus Acartia and cyclopid/mosquito interactions. The Maxilliped Lecture, given by Dr. Arthur G. Humes of Boston University, clearly established the importance of copepods to the earth's organic diversity. The book consists of selected research articles from the different sections. The articles published here reflect the diverse research interests of copepodologists today, and are distinguished by their high quality. Their impact will ensure that this volume is consulted by a wide range of research biologists.

Ticks of Trinidad and Tobago: An Overview explores tick species prevalent in Trinidad and Tobago (T&T), their distribution, associated pathogens, their effects on the host, and control methods. The book also reviews the basic biology of ticks. Ticks are known to parasitize a wide range of hosts including mammals, reptiles and birds. These parasites are of veterinary and public health significance since they are responsible for the spread of a number of pathogens to humans and animals. Worldwide, ticks are responsible for billions of dollars in losses in the livestock industry annually due to the effects of these pathogens. Based on review of the literature from more than five decades, twenty-three species of both hard and soft tick have been discovered on the twin-island republic with a greater number of species in Trinidad. Tick genera observed and recorded included Argas, Ornithodoros, Amblyomma, Dermacentor, Haemaphysalis, Ixodes, and Rhipicephalus species. The tick species found in Trinidad and Tobago parasitize both wild and domestic species. Hosts include bats, fowl, equids, wild and domestic ruminants, birds, rodents, marsupials, and a variety of reptiles such as toads, tortoises, and snakes. Based on geographical location, most tick species discovered in T&T have also been recorded in other Caribbean islands in the archipelago, North, Central and South America. Both soft and hard tick species found in T&T have also been implicated in a number of blood-borne pathogens including Borrelia, Ehrlichia, Babesia, Hepatozoon, Rickettsia, and Anaplasma.
