Book excerpt: Their natural enemies largely determine the population size and dynamic behavior of many plant-eating insects. Any reduction in enemy number can result in an insect outbreak. Applied biological control is thus one strategy for restoring functional biodiversity in many agroecosystems. Predators and Parasitoids addresses the role of natural enemies i

This book was released on 2013-03-08 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: The protection of agricultural crops, forest, and man and his domestic animals from annoyance and damage by various kinds of pests remains a chronic problem. As we endeavor to improve pro duction processes and to develop more effective and acceptable tactics for achieving this protection, we must give high priority to all potentially useful techniques for the control and management of insects. Pest control is recognized as an acceptable and necessary part of modern agriculture. Methods employed vary greatly and tend to reflect compromises involving 3 determining factors: technological capability, economic feasibility, and social acceptability. How ever, these factors are also subject to change with time since each involves value judgments that are based on available information, cost, benefit considerations, the seriousness of the pest problem, and the political climate. Whatever method is chosen, energy resources continue to dwindle under the impact of increasing popu lation, and it is inevitable that greater reliance must be placed upon renewable resources in pest management. One alternative is the use of a pest management method that uses the energy of the pest's own biomass to fuel a self-perpetuating control system. The use of biological control agents for the control of pests has long been an integral part of the pest management strategy in crop production and forestry and in the protection of man and animals. The importance and unique advantages of the method are well recognized; numerous treatises deal with accomplishments and methodologies.

This book was released on 2017-12-11 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Insect Parasites and Predators of Insect Pests There are certain definite limitations to the possibilities of con trol of insect pests by the use of parasites. Only in exceptional cases can complete control be achieved by this means. In the great majority of cases different degrees of partial control are secured. For this reason the introduction of parasites should be considered as supplementary to the usual methods of mechanical and chemical con trol rather than as a alternative method. The reduction in numbers of the insect pest by the use of parasites renders outbreaks less fra quent, and control is then more readily accomplished by the use of sprays or other mechanical or chemical methods.

Available in PDF, EPUB and Kindle. Book excerpt: This book is about disease and death. It is an ecologist's view of Darwin's vivid evocation of Nature, red in tooth and claw. An international team of authors examines broad patterns in the population biology of natural enemies, and addresses general questions about the role of natural enemies in the population dynamics and evolution of their prey. For instance, how do large natural enemies like wolves differ from small natural enemies like bacterial diseases in their effects on prey abundance? Is it better to chase after prey, or sit and wait for it to come to you? How should prey behave in order to minimize the risk of being eaten? The answers are all in this fascinating senior undergraduate/postgraduate text.

This book was released on 2012-12-06 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the invited lectures presented in a symposium entitled "Evolutionary strategies of parasitic insects and mites" at the national meeting of the Entomological Society of America in Minneapolis, Minnesota, 2-5 December, 1974. The intent was to bring together biologists who have worked on arthropods that are either plant or animal parasites in order to foster consideration of general aspects of the parasitic way of life. There seems to be a deficiency of ecological and evolutionary concepts relating to parasitism, in contrast to the burgeoning literature on predation, and it appeared that an amalgamation of studies on plant and animal parasites might help development of some generalities. Since parasities are far more numerous than predators in the world fauna, or in any particular community, emphasis on their study is justified. I freely admit that para sitoids have been usefully regarded as predators by ecologists, and many concepts on predation have been derived from their study. Also, in whichever category one places the parasitoids, that is the one which contains the most species. However, from an evolu tionary point of view they show many characteristics that must be regarded as those of a parasite. Notably, they are small, highly specific to their host, highly coevolved with it, as a result many species can coexist, and their adaptive radiation has produced the majority of the species diversity seen on Earth today.
Download or read book Insects as Natural Enemies written by Mark Jervis and published by Springer Science & Business Media. This book was released on 2005-05-25 with total page 755 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past three decades there has been a dramatic increase in theoretical and practical studies on insect natural enemies. The appeal of insect predators, and parasitoids in particular, as research animals derives from the relative ease with which many species may be cultured and experimented with in the laboratory, the simple life cycles of most parasitoids, and the increasing demand for biological pest control. There is now a massive literature on insect natural enemies, so there is a great need for a general text that the enquiring student or research worker can use in deciding on approaches and techniques that are appropriate to the study and evaluation of such insects. This book fulfils that demand. A considerably updated and expanded version of a previous best-seller, it is an account of major aspects of the biology of predators and parasitoids, punctuated with information and advice on which experiments or observations to conduct, and how to carry them out. Guidance is provided, where necessary, on the literature that may need to be consulted on particular topics. While researchers can now refer to several books on parasitoids and predators, Insects as Natural Enemies is unique in emphasising practicalities. It is aimed at students and professional working in universities and both government and commercial institutes in the fields of pest management, agriculture, horticulture and forestry.
