Symbiosis


Book Description

Symbiosis, Volume II: Associations of Invertebrates, Birds, Ruminants, and Other Biota focuses on associations involving insects, birds, and terrestrial vertebrates, as well as ectosymbiosis and endosymbiosis. The selection first offers information on insects and their endosymbionts and insect ectosymbiosis. Discussions focus on distribution of endosymbioses in insects; behavior of symbionts during embryogeny; physiological problems of insect symbioses; and miscellaneous insect symbioses. The manuscript also elaborates on ectosymbiosis in wood-inhabiting insects and aquatic insects. The book takes a look at avian symbiosis and intestinal microorganisms of ruminants and other vertebrates, as well as areas in which symbiosis affects birds and biochemical processes in the lower part of the alimentary tract of ruminants and in nonruminants. The selection is a dependable reference for readers interested in the relationships of insects, birds, and terrestrial vertebrates.




Morphology and Systematics (Elateroidea, Bostrichiformia, Cucujiformia partim)


Book Description

Dieses Buch ist der zweite von vier Bänden der Reihe "Handbuch der Zoologie", die die Systematik, Morphologie und Biologie der Coleoptera behandeln. Die Bände beantworten alle Fragen zu Phylogenese, Evolution und Ökologie der Coleoptera. Der zweite Band umfasst die Unterordnungen Elateroidea, Bostrichiformia und Cucujiformia zum Teil. Er informiert über weltweite Verbreitung, Biologie, Morphologie aller Lebensabschnitte (einschließlich Anatomie) und Phylogenese und liefert Erläuterungen zur Taxonomie. Die morphologischen Abhandlungen sind besonders detailliert illustriert und enthalten SEM-Bilder, Zeichnungen und Habitus-Darstellungen.




Biology of the Plant Bugs (Hemiptera: Miridae)


Book Description

Plant bugs--Miridae, the largest family of the Heteroptera, or true bugs--are globally important pests of crops such as alfalfa, apple, cocoa, cotton, sorghum, and tea. Some also are predators of crop pests and have been used successfully in biological control. Certain omnivorous plant bugs have been considered both harmful pests and beneficial natural enemies of pests on the same crop, depending on environmental conditions or the perspective of an observer.As high-yielding varieties that lack pest resistance are planted, mirids are likely to become even more important crop pests. They also threaten crops as insecticide resistance in the family increases, and as the spread of transgenic crops alters their populations. Predatory mirids are increasingly used as biocontrol agents, especially of greenhouse pests such as thrips and whiteflies. Mirids provide abundant opportunities for research on food webs, intraguild predation, and competition.Recent worldwide activity in mirid systematics and biology testifies to increasing interest in plant bugs. The first thorough review and synthesis of biological studies of mirids in more than 60 years, Biology of the Plant Bugs will serve as the basic reference for anyone studying these insects as pests, beneficial IPM predators, or as models for ecological research.







Introduction to Forest and Shade Tree Insects


Book Description

This comprehenisive text approaches the subject from an ecological/evolutionary biological perspective. The assumption is that one cannot study forest insects without understanding the dynamics of the relationship between an insect and its host plant. This relationship includes knowing what factors control forest insect populations such as food, food quality, tree vigor, host selection, and symbiotic relationships. The authors also discuss tree-injuring insects from the perspective of their influence on tree physiology and growth as well as economic and commercial effects. The book represents a "modern" approach to the topic of forest and shade tree insects; is well-illustrated; and includes a comprehensive primary reference list.







Novel aspects of the biology of Chrysomelidae


Book Description

Chrysomelidae, along with Curculionidae and Bruchidae, are the most important phytophagous Coleoptera. At least 37,000 species of leaf beetles belonging to 19 subfamilies have now been described, and more probably remain to be discovered, especially in the tropics. Many species are familiar agricultural pests. The Colorado potato beetle, the cereal beetle, flea beetle and the corn root worms are but a few of the well known pests. Because of the economic importance and biological diversity, chrysomelids are an important taxonomic group for scientific inquiry. This book is divided into eight parts, entitled palaeontology, larvae and larval biology, trophic selection, genetics and evolution defence mechanisms, anatomy and reproduction, pathogens and natural enemies, and general studies in biology. The biologies of agricultural and forestry pests, Leptinotarsa, Plagiodera, Entomoscelis, Paropsis, Mecistomela and Aspidomorpha are dealt with in detail. Others, such as Timarcha and those in the poorly known Megalopodinae, are covered in Part VIII. In this volume the American, European, Asian and Australian fauna occupy the greatest part. This volume, together with Biology of Chrysomelidae (1988), provides a comprehensive coverage and helps to complete the picture of chrysomelid biology.
