Download or read book Parasitoids written by H. Charles J. Godfray and published by Princeton University Press. This book was released on 2019-12-31 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: Parasitoids lay their eggs on or in the bodies of other species of insect, and the parasitoid larvae develop by feeding on the host, causing its eventual death. Known for a long time to applied biologists for their importance in regulating the population densities of economic pests, parasitoids have recently proven to be valuable tools in testing many aspects of evolutionary theory. This book synthesizes the work of both schools of parasitoid biology and asks how a consideration of evolutionary biology can help us understand the behavior, ecology, and diversity of the approximately one to two million species of parasitoid found on earth. After a general introduction to parasitoid natural history and taxonomy, the first part of the book treats the different components of the reproductive strategy of parasitoids: searching for a host, host selection, clutch size, and the sex ratio. Subsequent chapters discuss pathogens and non-Mendelian genetic elements that affect sexual reproduction; evolutionary aspects of the physiological interactions between parasitoid and host; mating strategies; life history theory and community ecology. A special effort is made to discuss the theoretical background to the subject, but without the use of mathematics.

This book was released on 1976-06-30 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Theory and Practice of Biological Control written by C.B. Huffaker and published by Elsevier. This book was released on 2012-12-02 with total page 811 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Theory and Practice of Biological Control covers conventional biological control achievement in the major crop types and in public health problems. Composed of five sections encompassing 28 chapters, this book discusses the basic information concerning developments in other biologically based alternatives to chemical pesticides. The first two sections discuss the philosophy, theory, scope, history, and the biological and ecological bases of biological control. These sections also deal with the impact of predators and the host relationships of parasitoids and pathogens. The following section presents the methodological aspects of biological control. Discussions on the variability of natural enemies as encountered in biological control work; the fitness of individuals and populations; the ways fitness is being or can be influenced by importation procedures; and the ability of imported natural enemies to adapt to the new environment are included. The fourth section outlines the accomplishments of conventional biological control in various types of crops, forests, and public health areas. Lastly, the various components of integrated pest control other than conventional biological control that forms the essential ways used in the integrated control approach are covered in the last section of the book. This book is an ideal source for plant pathologists and researchers, microbiologists, parasitologists, and public health professionals.
