Available in PDF, EPUB and Kindle. Book excerpt: Wheat breeders have achieved significant results over the last fifty years in research on mankind's one of the most important crops. Classical genetic and breeding methods, far broader international cooperation than was experienced in earlier periods, and improvements in agronomic techniques have led to previously unimaginable development in the utilisation of wheat for human consumption. The contribution of wheat researchers is particularly noteworthy since these results have been achieved at a time when the world population has grown extremely dynamically. Despite this demographic explosion, of a proportion never previously experienced, thousands of millions of people have been saved from starvation, thus avoiding unpredictable social consequences and situations irreconcilable with human dignity. Despite these developments in many regions of the world food supplies are still uncertain and the increase in the world's wheat production has not kept pace with the population increase during the last decade. Due to the evils of civilisation and the pollution of the environment there is a constant decline in the per capita area of land suitable for agricultural production. Based on population estimates for 2030, the present wheat yield of around 600 million tonnes will have to be increased to almost 1000 million tonnes if food supplies are to be maintained at the present level.

Download or read book Biological Control of Insect and Mite Pests in Iran written by Javad Karimi and published by Springer Nature. This book was released on 2021-04-28 with total page 621 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book provides a reference to biological control of arthropod pests in agriculture and of public health importance in Iran. A quick glance over the literature shows a long history of biocontrol attempts in the country. Some historically important events highlighting the interest of Iranian academic, research and extension fields to the natural enemies and their applied aspects are provided. Iran, with an exception of the former USSR, was a pioneer in both basic and applied biocontrol in West Asia. The book consists of four parts: three parts for predators, parasitoids and pathogens, and last part for other approaches and analyses of the current state of biological control in Iran. The book provides the most up-to-date information on pest control and related topics of entomology in Iran. The chapters are written by scholars from major Universities and research centers in Iran.
Download or read book Prospects for Biological Control of Plant Feeding Mites and Other Harmful Organisms written by Daniel Carrillo and published by Springer. This book was released on 2015-04-30 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: The history of biological control of harmful organisms by mites is marked by outstanding achievements with a few premiere natural enemies. Early works concentrated on the use of predatory mites for the control of synanthropic flies, More recently, the focus has been mostly on mites of the family Phytoseiidae for the control of plant feeding mites. This is an important family of acarine predators of plant pest mites, which are effectively used in agriculture worldwide. Besides the vast knowledge in several species in this family, there are as well many opportunities for biological control, represented in an array of organisms and through the improvement of management techniques, which are constantly explored by researchers worldwide. This has resulted in an increasing interest in predatory mite species within the families Stigmaeidae, Ascidae, Laelapidae, Rhodacaroidea, Macrochelidae, Erythraeidae and Cheyletidae, among others. This book will compile important developments with predatory mite species within these families, which are emerging as important tools for integrated pest management. New developments with predatory insects and pathogenic organisms attacking mites will also be a subject of this book. Finally, the potential and gaps in knowledge in biological control of acarine plant pests will be addressed.
Download or read book Invasive Stink Bugs and Related Species Pentatomoidea written by J.E. McPherson and published by CRC Press. This book was released on 2018-01-17 with total page 864 pages. Available in PDF, EPUB and Kindle. Book excerpt: Key features: Presents a brief history of past classifications, a summary of present classification, and speculation on how the classification may evolve in the future Includes keys for the identification of families and subfamilies of the Pentatomoidea and for the tribes in the Pentatomidae Explains transmission of plant pathogens and concepts of pathology and heteropteran feeding for the non-specialist Provides an extensive literature review of transmission by stink bugs of viral, bacterial, fungal, and protozoan organisms that cause diseases of plants Discusses the diversity of microbial symbionts in the Pentatomidae and related species, showing how microorganisms underpin the evolution of this insect group Reviews semiochemicals (pheromones, kairomones, allomones) of the Pentatomoidea and their vital role in the life histories of pest and beneficial species and their exploitation by natural enemies of true bugs Covers past, current, and future control options for insects, with a focus on stink bugs and related heteropterans The Superfamily Pentatomoidea (stink bugs and their relatives) is comprised of 18 families with over 8,000 species, the largest of which is the family Pentatomidae (about 5,000 species). These species primarily are phytophagous, and many cause tremendous economic damage to crops worldwide. Within this superfamily are six invasive species, two that occur worldwide and four that are recent invaders in North America. Once established in new geographic regions, these species have increased their numbers and geographic distributions dramatically, causing economic damage totaling billions of dollars. Invasive Stink Bugs and Related Species (Pentatomoidea): Biology, Higher Systematics, Semiochemistry, and Management is the first book that presents comprehensive coverage of the biology of invasive pentatomoids and related true bug species and addresses issues of rapidly growing economic and environmental concerns. Containing the contributions of more than 60 stink bug specialists from 15 countries, this book provides a better understanding of the biology and economic importance of these invasive species, why they became invasive, and how their continued geographical expansion is likely to affect numerous agricultural systems and natural environments. Including over 3,500 references, this authoritative work serves as an access point to the primary literature on their life histories, higher systematics, diapause and seasonal cycles, pathogens, symbionts, semiochemistry, and pest management control strategies for pentatomoid bugs.
Download or read book Biological Control by Augmentation of Natural Enemies written by R. Ridgway and published by Springer Science & Business Media. 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.
