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 2014-10-02 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chrysoperla carnea (Stephens) plays a prominent role in suppressing pest at early stages of cotton crops. It controls the pests of different crops and recommended for biological control programmes against insect pest. The most common species, C. carnea is widely used and studied for its host preference and reproductive and predatory potential on different pest species. However, the information on survival and predatory potential of this predator the requirement of host eggs of Corcyra cephalonica for this species is lacking Intensive cultivation and use of high yielding varieties under the umbrella of chemical pesticides have increased the pest problem. In the high yield production competition the cultivator has used the weapon of pesticide application for pest control on large scale. Due to the excessive and indiscriminate use of pesticide, Several problems have been developed viz. development of resistance to insect pest, resurgence and distribution of pest, disturbance to natural enemies, environmental pollution, toxic residues etc. Bioagent is an important being ecologically safe, economically viable and also effective against pest of crops.

Download or read book Use of Parasitoids as a Biocontrol Agent in the Neotropical Region written by Yelitza Colmenarez and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The agricultural production in the Neotropical region is highly affected by the attack of pests and diseases. Due to the overuse of pesticides, sustainable methods of control are in demand, such as biological control. Integrated Pest Management (IPM) considered the use of Biological control as a method to suppress the population of pests in several field agricultural systems and in protected crops systems. Biological control is generally appreciated today as an important component of IPM, and the demand for it is likely to spread as the IPM programs develop worldwide. The tropics present an important region for the application of biological control. The Neotropical region is characterized by its rich biodiversity, resulting in a wide range of natural enemies of pests represented by parasitoids, predators, and pathogens. Parasitoids are the natural enemies most used around the world for biological control. In this chapter, we present biological control programs using parasitoids established in the Neotropical region to control key pests of economic importance. Agricultural practices that maintain and enhance the action of natural enemies in crops will be reviewed, as the challenges and potential for the establishment of Biological Control programs using parasitoids in the Neotropical region.
Download or read book Epigenetics in Plants of Agronomic Importance Fundamentals and Applications written by Raúl Alvarez-Venegas and published by Springer. This book was released on 2014-07-22 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past decades, chromatin remodelling has emerged as an important regulator of gene expression and plant defense. This book provides a detailed understanding of the epigenetic mechanisms involved in plants of agronomic importance. The information presented here is significant because it is expected to provide the knowledge needed to develop in the future treatments to manipulate and selectively activate/inhibit proteins and metabolic pathways to counter pathogens, to treat important diseases and to increase crop productivity. New approaches of this kind and the development of new technologies will certainly increase our knowledge of currently known post-translational modifications and facilitate the understanding of their roles in, for example, host-pathogen interactions and crop productivity. Furthermore, we provide important insight on how the plant epigenome changes in response to developmental or environmental stimuli, how chromatin modifications are established and maintained, to which degree they are used throughout the genome, and how chromatin modifications influence each another.

Download or read book Evolutionary Ecology of Plant Herbivore Interaction written by Juan Núñez-Farfán and published by Springer Nature. This book was released on 2020-07-30 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant-herbivore interactions are a central topic in evolutionary ecology. Historically, their study has been a cornerstone for coevolutionary theory. Starting from classic ecological studies at the phenotypic level, it has since expanded to molecular and genomic approaches. After a historical perspective, the book’s subsequent chapters cover a wide range of topics: from populations to ecosystems; plant- and herbivore-focused studies; in natural and in man-modified ecosystems; and both micro- and macro-evolutionary levels. All chapters include valuable background information and empirical evidence. Given its scope, the book will be of interest to both students and researchers, and will hopefully stimulate further research in this exciting field of evolutionary biology.

This book was released on 2002 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: This review supports the conclusion that overall the currently commercialized biotechnology-derived soybean, corn, and cotton crops yield environmental benefits. Furthermore, a critical analysis of the literature supports the idea that biotechnology-derived soybean, corn, and cotton pose no environmental concerns unique to or different from those historically associated with conventionally developed crop varieties.
Download or read book Latin America and the Caribbean LAC Report written by International Assessment of Agricultural Knowledge, Science, and Technology for Development (Project) and published by Iaastd. This book was released on 2009 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: The International Assessment of Agricultural Knowledge, Science, and Technology for Development (IAASTD) looks realistically at how we could effectively use agriculture/AKST to help us meet development and sustainability goals. An unprecedented three-year collaborative effort, the IAASTD involved more than 400 authors in 110 countries and cost more than $11 million. It reports on the advances and setbacks of the past fifty years and offers options for the next fifty years. The results of the project are contained in seven reports: a Global Report, five regional Sub-Global Assessments, and a Synthesis Report. The Global Report gives the key findings of the Assessment, and the five Sub-Global Assessments address regional challenges. The volumes present options for action. All of the reports have been extensively peer-reviewed by governments and experts and all have been approved by a panel of participating governments. The Sub-Global Assessments all utilize a similar and consistent framework: examining and reporting on the impacts of AKST on hunger, poverty, nutrition, human health, and environmental/social sustainability. The five Sub-Global Assessments cover the following regions: Central and West Asia and North Africa (CWANA) East and South Asia and the Pacific (ESAP) Latin America and the Caribbean (LAC) North America and Europe (NAE) Sub-Saharan Africa (SSA)

Available in PDF, EPUB and Kindle. Book excerpt: This book aims to address the importance of natural enemies and functional diversity for biological control in Neotropical agroecosystems. Several aspects related to the conservation of natural enemies, such as vegetation design and climate change, are discussed in Part 1 and the bioecology of several insects groups used in biological control in Latin America is presented in Part 2. Part 3 is devoted to mass production of natural enemies while Part 4 describes how these insects have been used to control of pests in major crops, forests, pasture, weeds and plant diseases. Lastly, Part 5 reports Latin-American experiences of integration of biological in pest management programs.
