Available in PDF, EPUB and Kindle. Book excerpt: For many years the use of chemical agents such as pesticides and herbicides has been effective in controlling the many varieties of pests that infest both agricultural crops and backyard gardens. However, these pests are gradually becoming resistant to these agents, because the agents themselves are acting as selective factors making the pests better and better able to resist and persist. As a result, the use of biological controlling agents is increasing. This book is a comprehensive and authoritative handbook of biological control.

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.

Download or read book Arthropod Venoms written by S. Bettini and published by Springer Science & Business Media. This book was released on 2013-03-13 with total page 998 pages. Available in PDF, EPUB and Kindle. Book excerpt: Arthropod venoms have received much attention and have played an important role in folklore and medicine since ancient times. Scorpion envenomation, "tarant ism," bee and wasp stings are among those subjects about which most has been speculated and written in the past. In the last 50 years or so, a great number of scientific papers have been devoted to arthropod venoms, but only a few volumes have been designed to collect this rapidly increasing material, and these are not recent. Of late, the chemistry and mode of action of several arthropod venoms have been thoroughly studied, and some of these substances will probably be used as pharmacological tools and also as therapeutic agents. The aim of the present volume is to collect in manual form new information as well as the old notions on arthropod venoms. Even though it was our intention to present a volume on arthropod venoms, and not on venomous arthropods, inevitably we were forced to include information on venom-producing organisms as well. We assumed, in fact, that those scientists for whom the present manual is primarily intended (biochemists, particularly com parative biochemists, and pharmacologists) should be familiar with the biologic elements concerning the venom-producing species; which should show them how important it is to operate in close collaboration with biologists specialized in venomous arthropod systematics and biology.
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.
