The behaviour of these bees has been adapted to some extent to meet beekeeping requirements but few advances have been made in altering their behaviour so that honey and wax production is increased. Bee pheromone research aims to identify the pheromones and make analogous synthetic chemicals thus allowing the control of the colony's activities and enhancing honey production. This book evaluates the present state of knowledge of each known pheromone, discusses the pheromones of the stingless bees and describes the effect of pheromones on the social organization and mating behaviour of bumblebees. Suggestions are made for further and different types of research into pheromones. The book should be of interest to zoologists, entomologists and general biologists.
Fruit flies (Diptera: Tephritidae) are among the most destructive agricultural pests in the world, eating their way through acres and acres of citrus and other fruits at an alarming rate and forcing food and agriculture agencies to spend millions of dollars in control and management measures. But until now, the study of fruit flies has been traditionally biased towards applied aspects (e.g., management, monitoring, and mass rearing)-understandable, given the tremendous economic impact of this species.
When Franklin published her book on cyst nematodes in 1951, the cyst nematodes were already known as serious pests of brassicas, cereals, potatoes and sugar beets. However, at that time this group of nematode, with about 12 species, was considered tobe largely temperate in distribu tion. Now a total of 105 species (including those that are considered as synonyms or species inquirende by some or all) within six genera of cyst nematodes have been described from temperate, tropical, and subtropical regions and at least five species are important constraints to crop produc tion in tropical agriculture. The previous impression of localization of cyst nematodes in the temperate region was seemingly an artifact due to a greater concentration of nematologists in the temperate regions. Based on my own experience of working in several Asian and African countries, I believe that many more undescribed species are present in the tropical countries of Asia and Africa, and probably in other tropical regions. Most growers, extension workers, and research managers in these regions are still not aware of the possible harm of presence of these nematodes in their agricultural soils. The cyst nematodes are perhaps smaller than the smallest available computer chip but they are very well programmed to survive and pro pagate despite severe hardships. These nematodes are very selective in their choice of food; about 50% of known species are parasites of plants mainly in the families Poaceae and Fabaceae."
This volume of the Subcellular Biochemistry series is the result of the long-standing research interest of the editor in the molecular mechanism underlying Alzheimer's disease and other amyloid diseases, indicated also by the earlier book in the series (Volume 38), devoted to Alzheimer's disease. The broad coverage within the present amyloidogenesis book represents an attempt to collate current knowledge relating to the proteins and peptides involved in most of the known amyloid diseases, together with some amyloid/fibril-forming proteins and peptides that are not involved in diseases. Thus, the range of topics included is comprehensive and furthermore it was thought appropriate to include both basic science and clinical presentation of the subjects under discussion.
"Handbook of Agricultural Entomology" by Helmut van Emden is a landmark publication for students and practitioners of entomology applied to agriculture and horticulture. It can be used as a reference and as a general textbook. The book opens with a general introduction to entomology and includes coverage of the major insects (and mites) that cause harm to crops, livestock and humans. The important beneficial species are also included. Organisms are described in a classification of insect Orders and Families. The emphasis is on morphological characters of major taxonomic divisions, "spot characters" for the recognition of Families, and the life histories, damage symptoms and economic importance of the various pest species. The book is beautifully illustrated in full colour with more than 400 figures showing both the organisms and the damage caused to plants with diagnostic characters indicated by arrows. Coverage is world-wide and includes much material stemming from the vast personal experience of the author.A companion website with additional resources is available at www.wiley.com/go/vanemden/agriculturalentomology
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."
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.
Groundwater Ecology and Evolution, Second Edition is designed to meet a multitude of audience needs. The state of the art in the discipline is provided by the articulation of six sections. The first three sections successively carry the reader into the basic attributes of groundwater ecosystems (section 1), the drivers and patterns of biodiversity (section 2), and the roles of organisms in groundwater ecosystems (section 3). The next two sections are devoted to evolutionary processes driving the acquisition of subterranean biological traits (section 4) and the way these traits are differently expressed among groundwater organisms (section 5). Finally, section 6 shows how knowledge acquired among multiple research fields (sections 1 to 5) is used to manage groundwater biodiversity and ecosystem services in the face of future groundwater resource use scenarios. Emphasis on the coherence and prospects of the whole book is given in the introduction and conclusion.
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.
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.
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.
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.
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.
The Frit Flies (Chloropidae, Diptera) of Fennoscandia and Denmark is written by two leading experts on this large and difficult group of small to minute flies, Dr Emilia P. Nartshuk, Zoological Institute Academy of Sciences, St Petersburg, Russia, & Dr Hugo Andersson (deceased in 2008), Zoological Institute, Lund University, Sweden. The book covers the North European fauna of frit flies that totals 209 species in 48 genera including 11 species and 1 genus described as new to science. Several species are economically important as notorial pests of cereals and fodder grasses. This is the first comprehensive treatment ever of the entire North European fauna of frit flies. It primarily facilitates species identification, but further summarizes existing knowledge about nomenclature, biology, faunistics and literature. Keys are given to subfamilies, genera and species for the adults and for the known larvae to genus or even species level. The text is supplemented with numerous illustrations of characters of diagnostic importance. Species distributions in the Nordic countries are detailed in a catalogue.
A richly illustrated natural history of ants, covering their diversity, ecology, anatomy, behavior, and more Plentiful and familiar, ants make up an estimated one-third of the world's insect biomass and can be found in virtually every part of the globe, from rain forest canopies to city sidewalks. But their importance is about more than numbers: ants are fundamental species in a range of habitats and their interactions with plants, fungi, and other animals ensure the survival of many fragile and complex ecosystems. This beautifully illustrated book explores the extraordinary diversity of ants and offers insights into their elaborate social systems, investigating the key collective and competitive behaviors that operate within their varied colony structures. Featuring exceptional close-up photographs and clearly organized thematic chapters, the book covers anatomy, evolution, life cycle, ecology, and other important topics. Each chapter also features profiles of standout genera, chosen for their fascinating characteristics, including Leafcutter Ants, who build nests containing up to 7,000 chambers; Pugnacious Ants whose colonies can destroy populations of crabs within hours; and Honeypot Ants whose worker caste store food in their stomachs for other colony members to consume. Drawing on current research, Ants offers an inviting and accessible introduction to these remarkable insects. Includes more than 200 stunning color photographs, plus infographics and diagrams Presents full profiles of 42 iconic genera from across the world Features clearly structured thematic chapters |
