The global drive towards sustainability and improved animal health means there is a greater need for development of novel functional ingredients for the feed industry. As the requirements for protein for livestock feed and human consumption grows, the use of insect products as animal feed has gained increasing attention. Covering global production systems of insect protein, oil and chitin, as well as co-products from this industry, this book: - Considers in-depth nutritional and safety aspects of insects for feed. - Reviews suitability of insects as feed for different animal species and life stages. - Examines current knowledge of the value of insect-rearing residues as biofertilizers for crop health. - Identifies the challenges related to regulation, legislation, consumer perception and acceptance, and commercialization of insects. - Provides interviews with established and early-stage innovative companies producing insect protein for feed. Including a focus on practices such as waste valorization, this book takes a holistic look at how insects could contribute to the sustainability of livestock production on a global scale. Providing an up-to-date reference for research scientists, nutritionists, and veterinarians, as well as prospective insect farmers, it will also be of interest to those with a broader curiosity towards climate change, sustainability, and the circular economy.

The Bees of the World (Hardcover, second edition): Charles D. Michener The Bees of the World (Hardcover, second edition)
Charles D. Michener
R4,486 Discovery Miles 44 860 Ships in 12 - 19 working days

In this extensive update of his definitive reference, Charles D. Michener reveals a diverse fauna that numbers more than 17,000 species and ranges from the common honeybee to rare bees that feed on the pollen of a single type of plant. With many new facts, reclassifications, and revisions, the second edition of The Bees of the World provides the most comprehensive treatment of the 1,200 genera and subgenera of the Apiformes. Included are hundreds of updated citations to work published since the appearance of the first edition and a new set of plates of fossil bees.

The book begins with extensive introductory sections that include bee evolution, classification of the various bee families, the coevolution of bees and flowering plants, nesting behavior, differences between solitary and social bees, and the anatomy of these amazing insects. Drawing on modern studies and evidence from the fossil record, Michener reveals what the ancestral bee -- the protobee -- might have looked like. He also cites the major literature on bee biology and describes the need for further research on the systematics and natural history of bees, including their importance as pollinators of crops and natural vegetation. The greater part of the work consists of an unprecedented treatment of bee systematics, with keys for identification to the subgenus level. For each genus and subgenus, Michener includes a brief natural history describing geographical range, number of species, and noteworthy information pertaining to nesting or floral biology.

The book is beautifully illustrated with more than 500 drawings and photographs that depict behavior, detailed morphology, and ecology. Accented with color plates ofselect bees, The Bees of the World will continue to be the world's best reference on these diverse insects.

There has been a considerable upsurge in interest in insect bio chemistry and physiology in recent years and this has been reflected in a notable expansion in the number of original papers in this field. Whereas insect physiology has tended to receive ample attention from reviewers, the same has not always been true for the more biochemical aspects of insect research. This book is a venture to help redress the balance. No attempt has been made to cover all aspects of insect biochemistry, but rather a few topics have been selected which seemed to us to merit a review at the present time. One reason for this increased interest in insect biochemistry is perhaps the growing realization that insects can be very useful organisms to act as model systems for the experimental study of general biochemical principles. One remembers, for instance, that Keilin's perceptive observations on the flight muscles of living bees and wax moths led to his discovery of the cytochromes. The fundamental unity of biochemistry has long been accepted as a dogma by the faithful and the insect kingdom provides no exception to it. The main biochemical processes in insects are being revealed as essentially the same as in other life forms but, as so often found in comparative biochemistry, there are interesting variations on the central theme."

In his preface to early editions of this book, the late Dr. A. D. Imms said that he intended it to be an elementary account of entomology as a branch of general biology. He had especiaHy in mind the needs of university students of zoology and agriculture, as weH as those intending later to specialize in entomology, and he suggested that the book might also interest teachers of advanced biology in schools. These general aims and the balance between the different aspects of the subject have changed linIe in this and in our previous revision. We have, however, tried to bring the present edition up to date on the lines of our revised tenth edition of Imms' General Textbook 0/ Entomology, published in 1977. The text has been entirely re-set and eleven illustrations have been replaced by new figures. The same orders of insects are recognized as in the last edition, but the sequence in which the Endopterygote groups appear has been changed to reflect more accurately their probable evolutionary relationships. Many small changes and some addi tions have been made in the physiological sections, the chapter on the origin and phylogeny of insects has been rewritten, and a new bibliography provides a selection of modern references for the in tending specialist. It has been our object to make these alterations without materially increasing the length of the book or its level of difficulty."

A single pair of antennae (homologous with the anten nules of the Crustacea) is present and the head also bears a pair of mandibles and two pairs of maxillae, the second pair fused medially to form the labium. The thorax carries three pairs of legs and usually one or two pairs of wings. The abdomen is devoid of ambulatory appendages, and the genital opening is situated near the posterior end of the body. Postembryonic development is rarely direct and a metamorphosis usually occurs."

Covering 100 years of zoological research, the Handbook of Zoology represents a vast store of knowledge. Handbook of Zoology provides an in-depth treatment of the entire animal kingdom covering both invertebrates and vertebrates. It publishes comprehensive overviews on animal systematics and morphology and covers extensively further aspects like physiology, behavior, ecology and applied zoological research. Although our knowledge regarding many taxonomic groups has grown enormously over the last decades, it is still the objective of the Handbook of Zoology to be comprehensive in the sense that text and references together provide a solid basis for further research. Editors and authors seek a balance between describing species richness and diversity, explaining the importance of certain groups in a phylogenetic context and presenting a review of available knowledge and up-to-date references. New contributions to the series present the combined effort of an international team of editors and authors, entirely published in English and tailored to the needs of the international scientific community. Upcoming volumes and projects in progress include volumes on Annelida (Volumes 1-3), Bryozoa, Mammalia, Miscellaneous Invertebrates, Nannomecoptera, Neomecoptera and Strepsiptera and are followed later by fishes, reptiles and further volumes on mammals. Background The renowned German reference work Handbook of Zoology was founded in the 1920's by Professor Willi Kukenthal in Berlin and treated the complete animal kingdom from single cell organisms to mammals in eight thematic volumes: Volume I Protozoa, Porifera, Colenteratea, Mesozoa (1925); Volume II Vermes (1933/34); Volume III Arthropoda ex. Insecta (1927/1932); Volume IV Arthropoda: Insecta; Volume V Solenogastres, Mollusca, Echinoderma (1925); Volume VI Pisces / Amphibia (1930); Volume VII Reptilia / Aves (1931); Volume VIII Mammalia. The Volumes IV Arthropoda: Insecta and VII Mammalia continued publication into the present with the most recent contributions in English language. Adapting to the accelerating speed of scientific discovery in the past decades the Handbook of Zoology entered a next phase in 2010. In the new edition of the Handbook of Zoology, the original eight thematic volumes gave way for smaller and more flexible groupings that reflect the current state of phylogenetic knowledge. All subsequent volumes were published in print as well as e-book format. The Handbook of Zoology is additionally offered as a database, the Handbook of Zoology Online, which can easily be searched and rapidly updated. Original Handbook material (ca. 28 000 pages) has been reordered along taxonomic (instead of bibliographical) categories and forms the historical basis of this Online Reference Work. As a living Online Reference, the content is continuously updated and new content added. The material can be accessed through taxonomic and subject categories as well as free text, with a diversity of linking and search options. Faster publication times through online-first publication, reference- and cross-linking, and make the Handbook of Zoology highly attractive to both authors and users.

G. D. May 1976 Part III THEORDERSOFINSECTS THE CLASSIFICATION AND PHYLOGENY OFINSECTS The classification of insects has passed through many changes and with the growth of detailed knowledge an increasing number of orders has come to be recognized. Handlirsch (1908) and Wilson and Doner (1937) have reviewed the earlier attempts at classification, among which the schemes of Brauer (1885), Sharp (1899) and Borner (1904) did much to define the more distinctive recent orders. In 1908 Handlirsch published a more revolutionary system, incorporating recent and fossil forms, which gave the Collembola, Thysanura and Diplura the status of three independent Arthropodan classes and considered as separate orders such groups as the Sialoidea, Raphidioidea, Heteroptera and Homoptera. He also split up the old order Orthoptera, gave its components ordinal rank and regrouped them with some of the other orders into a subclass Orthopteroidea and another subclass Blattaeformia.

When Patrick A. Buxton was appointed by the London School of Hygiene and Tropical Medicine in 1926 to head their Department of Medical Entomology, he had formed the opinion that the control of the insect-borne diseases of the tropics was being impeded by lack of knowledge about the physiology of insects. He persuaded the Board of Management to agree to the selection of a lecturer who would endeavour to advance the subject of insect physiology; and at the suggestion of Sir Gowland Hopkins, under whom I had worked at Cambridge, and with the support of Sir Walter Morley Fletcher, Secretary of the Medical Research Council and a member of the Board of Management, I was appointed to this post - with opportunity for extensive travel to study medical entomology in the tropics and with abundant time for research. Some seventeen years later, during the war years, W. W. C. Topley, as Secretary of the Agricultural Research Council, was faced with the urgent need for improved methods of control of insect pests in agriculture and horticulture by insecticidal or other means. As a support for this objective he recommended the establishment of a Unit of Insect Physiology to carry out basic research which would be of potential value to agriculture; and I was invited to act as director. So once again I was able to undertake world-wide travel - to learn the elements of agricultural entomology.

Diseases of insects are important factors reducing the number of insects in natural populations. They are density dependent and they act especially under conditions of outbreaks and close contact of susceptible hosts. They are im portant allies of man in his effort to replace toxic chemicals with non-toxic, biological means in the conservation of the environment of mankind. The importance of diseases as reducing factors has often been disregarded in studies on insect ecology and population dynamics. Most cases of mortality in carefully watched experiments have simply been characterized as "natural mortality," neglecting the fact that there is no "natural" mortality before the insects have finished their life assignment, the deposition of their eggs. The environmental factors including the pathogens are responsible for any other than natural mortality of the larvae, pupae and young adults of the pests. It is rather difficult to distinguish the different symptoms of a disease in insects. Therefore they are not noticed and their influence on populations is overlooked. We feel that a series of photographs of different stages of a collection of insect diseases could help such workers in a general orientation and we are sure from own experience that each specialist needs some broader oriented guide for the fields bordering his own homeland."

An analysis of the particular topics in biological control programmes all over the world indicates an increased interest in the utilization of aphid parasites. Besides the so-called traditional biological control of introduced aphids, there appears a situation which could perhaps be called a renaissance of biocontrol, i. e. the utilization of biotic agents against insecticide-resistant populations of aphid pests. The rapid increase in the amount of information as well as the necessity of syntheti- cal papers are the well-known features in today's entomology. This requirement is much more topical in the groups where brief summarized information is needed for research workers in applied branches. The author has been well aware of all these difficulties and requirements owing to his own experience both in basic and applied research. Several years ago he decided to summarize our knowledge on the aphid parasites of the world by elaborating synthetical studies on the particular zoogeographical areas.These papers have been intended to represent annotated reviews of the parasite fauna, distribution, biologies and utilization in aphid pest management, with keys to genera and species, hos- parasite catalogue, and a list of references added. Naturally, these studies are only relatively updated, with respect to a certain deadline from which the research may be further continued. At present, the Far East Asian and the Mediterranean areas have been reviewed in this or at least in a similar manner.

In past years there have been several unsuccessful attempts to arrange a symposium on Trichoptera. Letters from fellow workers suggested that now might be an appropriate time, and that a symposium should be held in Lunz. Today it is clear that large congresses are losing their value because of the difficulty of attending all relevant lectures and of finding colleagues. In consequence, small symposia for specialist groups are becoming increasingly important. As I felt that the success of such a symposium must depend on the suggestions from its potential members, I sent out in April 1973, together with a first circular, a questionnaire, asking for opinions on time and length of the symposium, numbers of participants, types of communication, interests within Trichopterology, and lan guages which should be used. The majority of answers suggested the following: The number of participants should be between 20 and 50, and the duration, excluding excursions, should be three to five days; main interests were in ecology and systematics, but there were also interests in physiology, behaviour, zoogeography, morphology, cytotaxonomy and evolution. There was a clear preference for local excursions. Languages should be English, French and German, with a preference for English. The symposium should consist of both formal papers and informal progress reports, with adequate time for discussion. The arrangements have therefore been based on these results."

by Professor L. E. Eastham Formerly Professor of Zoology in the University of Sheffield Most books are written with the intention of supplying some particular need, but few end with such single purpose. Mrs. Mellanby's is no exception, for while the author planned this work to serve as a guide to the school pupil, which function it fulfils in an admirable way, it will also prove of value to the teacher, the university student and the amateur naturalist. While it may be argued that it is not the function of the Uni versities to teach Natural History in the commonly accepted sense, it will always be the aim of Zoologists to know more about animals, what they are and do, where they live and why they live in particular environments. It is unfortunate, in view of the fact that the majority of students of Zoology enter the teaching pro fession, that the increasing load of instruction in morphology, physiology, cytology, genetics, evolution and the like frequently makes a personal study of animal life in relation to environment almost impossible. The fortunate ones visit the sea for a fort night's course in Marine Ecology; the others take posts in schools without even this respite and set about converting their academic learning to a school curriculum. The result is an undesirable and often slavish imitation of university method in the school class room."

Floricultural crops all over the world are challenged by a number of insect and mite pests. The pest scenario is changing, and with climate change the instances of new pest incidences have become a more common problem. Like other crops, the intensive cultivation of commercial flowers has accentuated pest problems, as farmers tend to use more agricultural chemicals, which, in turn, increase the problems of pesticide resistance, pest resurgence, and residues leading to health hazards. This volume, Advances in Pest Management in Commercial Flowers, looks at the major challenges and improvements in this growing area today. It first provides an informative overview of worldwide pests of important commercial flowers. It explores a number of important issues in this area, such as the role of climate change on insect pests of commercial flowers and the synthetic chemicals and their possible harmful effects on the environment.

The third in a trilogy of global overviews of conservation of diverse and ecologically important insect groups. The first two were Beetles in Conservation (2010) and Hymenoptera and Conservation (2012). Each has different priorities and emphases that collectively summarise much of the progress and purpose of invertebrate conservation. Much of the foundation of insect conservation has been built on concerns for Lepidoptera, particularly butterflies as the most popular and best studied of all insect groups. The long-accepted worth of butterflies for conservation has led to elucidation of much of the current rationale of insect species conservation, and to definition and management of their critical resources, with attention to the intensively documented British fauna leading the world in this endeavour. In Lepidoptera and Conservation, various themes are treated through relevant examples and case histories, and sufficient background given to enable non-specialist access. Intended for not only entomologists but conservation managers and naturalists due to its readable approach to the subject.

It is now generally accepted for a variety of reasons - morphological as well as physiologica- that the visual systems of arthropods provide a suitable model for the study of information proces sing in neuronal networks. Unlike the neurophysiology of the visual pathway in the frog and the cat which is more than adequately documented, recent work on the compound eye and optical ganglia of spiders, crustaceans, and insects has scarcely been summarized. In order to fill this void so that others, especially vertebrate neurophysiologists may become familiar with the advan tages of these systems, our group at Zurich University organized here in March 1972, a European meeting to discuss the anatomical. ! neurophysiological and behavioral knowledge on the compound eye and the visual. pathway of arthropods. Systems analysis was regarded as the main theme of the conference, but systems analysis of a network of neurons cannot be done as a mere "black-box" maneuver. The conference therefore tried to reconcile neurophysiology and behavioral analysis in order to make predictions about a necessary and sufficient neural structure. The "wiring dia grams" of such a structure might then be confirmed histologically. Hence the aim of the conferen ce was not to deal only with the structure and function of the compound eye - i. e.

Jurgen Tautz, renowned German bee researcher explains how bees communicate. Exciting and surprising new insights on communication between bees. During the history of bee research, scientists have peered deep into the inner life of bee colonies and learned much about the behaviour of these insects. Above all, the bee waggle dance has become a famous and extensively discussed phenomenon. Nevertheless, recent insights reveal that while bees are social insects inside the hive they also communicate with one another outside the hive. In this book, Jurgen Tautz, renowned German bee researcher, provides an entertaining, fresh and enlightened account for lay and professional readers, not only about the fascinating dance language but also about additional remarkable phenomena concerning information exchange between bees. From the author of the bestseller "The Buzz about Bees". "The Language of Bees" assembles, for the first time, a complete overview of how bees understand one another. Although communication biology research on bees has so far concentrated largely on events within the hive, this book directs attention as well, to how bees communicate in the field outside the hive. The reader learns which steps new bee recruits take to reach the feeder a dancing forager has advertised. The book analyses the status of work on the bee dance published over the last 100 years and orders the essential findings as building blocks into a coherent new concept of how bees find their target. In addition, the historical survey of research on the "Bee Language" explains how several contradictory and incomplete hypotheses can still survive. A fresh point of view on one of the most remarkable behavioural performances in the animal kingdom. Observation from a different viewpoint leads to previously unknown insights. Such new perspectives clearly reveal both how large the gaps in our knowledge still are in relation to the language of bees and in which direction research must take to complete the picture of one of the most impressive behavioural accomplishments in animals. Prof. Dr. Jurgen Tautz is an expert on bees, sociobiologist, animal behaviourist and emeritus professor at the Biozentrum, University of Wurzburg. He is a bestseller author and recipient of many awards of excellence for his successful communication of science to a wide public.

Bees existed long before human beings, but our future is perhaps more reliant upon them than any other species. They pollinate 80 per cent of the world's crops and plants, but how much do we really know about them? Small, clever and mysterious, the honeybee in particular has long been celebrated in human culture as a sacred insect, a symbol of the sun, bridging the gap between our world and the next. They are expert communicators, skilled aviators and natural alchemists, turning fresh nectar into sweet, golden honey. They are also in trouble and need our help. This beautifully illustrated guide explores the honeybee's historic relationship with humans, the basics of beekeeping, and how we can help save the bees' dwindling population.
