This book was released on 1982 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The practice of growing varieties, lines or hybrids resistant to attack by insects, and their subsequenty effectiveness in reducing pest populations and corresponding crop losses, is well documented for several agricultural crops and pest species. The development of many of these resitant cultivars has resulted from or been facilitated by many years of study of the insect pests, the development of techniques to mass rear the insects, artificially infest the crop species, and screen the germplasm of the species (or their wild relatives) for resistance, and the successful application of appropriate breending procedures for improvement of the resistance characteristic over succeeding cycles or generations of population improvement (Guthrie, 1974, 1980). The basic components necessary to identify or developed germaplasm with resitance, or with higher levels of resistance than present cultivars utilized by farmer/producers, include: (1) A colony of the insect species, which exhibits the vigor and vitality of the damaging pest population within the geographical area that is affected. (2) The capability to efficiently mass culture the species, including the rearing facility, trained personnel, natural, meridic, or defined diets, and rearing procedures and containers. (3) Germaplasm resources that area representative of the genetic variation within the crop and/or its closely related species. (4) Methods for uniform artificial infestation. (5) Methods for assessing resultant damage, or lack of damage, to the plants subjected to deliberate infestation (rating scales to determine classes or categories of resistance or susceptibility). (6) Screening to determine whether adequate levels of resistance exist within suitable agronomic types (equivalent or better than currently grown cultivars), and effective selection/breeding scheme established to improve either the resistance levels or agronomic characteristics of the "improved" materials.

This book was released on 2018-03-18 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Artificial Diets for Mass Rearing the Corn Earworm (Heliothis Zea) Each cup was charged with 10 milliliters of diet from a prepared batch of milliliters. The cups were placed in groups of 25 in a cel-pack tray, infested with 1 day-old, processed H. Zea eggs,5 and capped. Four groups of 25 cups were placed in a bundle (four replications) and held in an environmental room at. 84° 'to 85° F. And 55 to 60 percent rela tive humidity for the duration of the egg, larval, and pupal stages. The biological criteria considered in evaluating the diets were days to pupation, days to emergence, percentage viable adults, fecund ity, percentage egg hatch, adult longevity, mating, and type of sperm complements. Forty cages per diet were used to evaluate adult performance, that is, four cages containing six pairs of adults from each of the 10 trials. The adults were held at 78° to 80° F. And 75 to 80 percent relative humidity and were fed. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book Synopsis Biological and Biotechnological Control of Insect Pests by : Jack E. Rechcigl
Download or read book Biological and Biotechnological Control of Insect Pests written by Jack E. Rechcigl and published by CRC Press. This book was released on 1999-09-24 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pest and disease management continues to challenge the agricultural community. The rise in new pest and crop problems juxtaposed with public concern over pesticide use and more stringent environmental regulations creates the need for today's agricultural producers to stay current with new technologies for producing quality crops profitably. Biological and Biotechnological Control of Insect Pests presents an overview of alternative measures to traditional pest management practices, utilizing biological control and biotechnology. The removal of some highly effective broad-spectrum chemicals, caused by concerns over environmental health and public safety, has resulted in the development of alternative, reduced risk crop protection products. These products, less toxic to the environment and easily integrated into biological control systems, target specific life stages or pest species. Predation - recognized as a suitable, long term strategy - effectively suppresses pests in biotechnological control systems. Biological and Biotechnological Control of Insect Pests covers these topics and more. It explores the current approaches in alternative solutions such as: biological control agents, parasites and predators, pathogenic microorganisms, pheromones, botanical insecticides, genetic control, genetic engineering of plants and biocontrol agents, and government regulations for biocontrol agents and recombinant DNA technology. This book will be a useful resource to entomologists, agronomists, horticulturists, and environmental scientists.
