Smith) (Lepidoptera: Noctuidae), to Bacillus Thuringiensis Toxins written by Karen Ferreira da Silva and published by . This book was released on 2015 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fall armyworm, Spodoptera frugiperda, is a polyphagous insect pest affecting multiple crops. Fall armyworm is managed with insecticides and corn hybrids expressing insecticidal proteins derived from Bacillus thuringiensis. The early detection of insect resistance is important for making appropriate management decisions informs IPM and IRM recommendations. The objective of the first study was to establish baseline susceptibility of fall armyworm populations to the Cry1F Bt insecticidal protein, emphasizing collections from locations where fall armyworm overwinters in the U.S. Fall armyworm neonates were exposed to artificial diet treated with increasing Cry1F concentrations, and mortality and growth inhibition were evaluated after 7 days. Differences in Cry1F susceptibility between the most susceptible and the most tolerant field populations were 2- and 6- fold for 2012 and 2013, respectively. These results are consistent with other baseline studies of Bt toxicity in other species although reduced susceptibility in some populations may suggest resistance development. The second study was designed to identify possible sources of variability in laboratory bioassays. Efforts to standardize the laboratory methods used in bioassays of microbial products have been part of an overall attempt to minimize variation. The objective of this second project was to determine if pre-treatment conditions contribute to variation in a Spodoptera frugiperda laboratory population response when exposed to Vip3Aa19 insecticidal protein. Neonates were exposed to the LC70 of Vip3Aa19 under five pretreatment conditions: 1) larval storage time prior to exposure, 2) prior feeding on artificial diet, 3) larval storage at reduced temperature, 4) larval storage at reduced humidity, and 5). lab colony introgression with field collected individuals. Extremes of photoperiod settings used during the course of the bioassay itself were also tested. Significant effects of pre-treatment conditions were observed when neonates were fed prior to bioassay, when stored overnight at 14oC and when exposed to extreme photoperiod conditions. There was no significant difference observed in the other pretreatment conditions.
Book Synopsis Polyphagous Pests of Crops by : Omkar
Download or read book Polyphagous Pests of Crops written by Omkar and published by Springer Nature. This book was released on 2021-01-04 with total page 539 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polyphagous pests are primarily agricultural pests that feed on economically important agricultural and horticultural crops of wide taxonomic diversity across the globe. They cause immense damage across different crop varieties owing to their generalist and voracious food habits. The advent of mono-crop culture in a huge area and the massive use of pesticides post green revolution have massively increased pest outbreaks all over the world. The Middle Eastern countries, African continent and even the Indian subcontinent is increasingly facing resurgences of polyphagus pests. This book compiles an inclusive account of polyphagous pests. It covers locusts, termites, aphids, whiteflies, mealybugs, scale insects, gram pod borer, fall armyworm, thrips, mites and rodents. The book discusses mode of spread, enormity of losses caused, mechanism of action, and also means to reduce the crop losses. It brings together a unique perspective for researchers to learn effective pest management practices across all crops. This book is a reference guide to researchers and also useful for academicians and students of entomology.

Download or read book Community-based fall armyworm (Spodoptera frugiperda) monitoring, early warning and management written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2019-02-12 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fall Armyworm (FAW) (Spodoptera frugiperda) was first reported in Africa in 2016. Since then, it has become a very destructive invasive pest in sub-Saharan Africa. Its main impact is on maize crops and affects different stages of growth, from early vegetative to physiological maturity. In several countries affected by FAW attack, farmer responses have been predominantly based on the use of chemical pesticides. It is important to ensure the safe use of such pesticides by farmers, but also to promote and deploy an integrated pest management (IPM) package against FAW. Farmers need the right advice, tools and resources to sustainably manage FAW. This manual provides farmers and extension service providers easy-to-use information on how they can manage FAW in smallholder cropping systems. It provides information about modules for training trainers in FAW pest diagnostics, scouting, management and data collection. The objective of this training is to provide trainers and farmers with the knowledge and skills that will enable them to identify FAW and differentiate it from other similar pests; understand the life cycle of FAW; and, know how to monitor and manage the pest. This manual gives trainers the information they need in order to support and sustain an IPM approach for FAW management in their communities. The manual is modular and allows for updates in the future as more knowledge and solutions to manage FAW become available.

Book Synopsis Technical guidance on fall armyworm by : Food and Agriculture Organization of the United Nations
Download or read book Technical guidance on fall armyworm written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2022-05-27 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: Worldwide, maize is the third most important cereal after rice and wheat. It occupies 197 million hectares of planted area. Asia contributes to nearly 30 percent of global maize supplies, and area and production of the crop is rapidly increasing in the continent. Minimum support prices, swelling market demand from the animal feed and processing industries, as well as human consumption, have all led to increased maize production in zones where precipitation limits rice cultivation. However, maize production is currently threatened by the arrival in Asia (in 2018) of the fall armyworm (FAW), Spodoptera frugiperda (J. E. Smith) – a native to North America. It invaded India in 2018 and since then it has marched to most of the Asian countries. In 2019, its presence was confirmed in 13 Asian countries including Cambodia, China, India, Indonesia, Japan, the Lao People’s Democratic Republic, Malaysia, Myanmar, Nepal, the Philippines, the Republic of Korea, Sri Lanka, and Viet Nam. In 2020, it was confirmed in Australia, Timor-Leste and Papua New Guinea. In August 2021, it reached the Solomon Islands, posing a serious threat to other Pacific islands. FAW is a fast-dispersing, migratory, transboundary insect pest. While high FAW incidences have been reported on several crops in Asia, the most important economic damage caused is to maize (followed by sorghum). The FAW invasion threatens the food security of millions of family farms in Asia, with smallholder farmers being especially vulnerable. The negative economic impact of FAW is not only evident in yield loss: the pest also leads to a significant increase in insecticide applications, with associated health, environmental and cost issues. At the same time, resilience to FAW on the continent is currently weakened by the limited access to necessary tools, technologies and sustainable integrated pest management (IPM) practices for FAW. Thus, there is an urgent need to implement an effective approach to FAW management in Asia.

Book Synopsis Genetically Engineered Crops by : National Academies of Sciences, Engineering, and Medicine
Download or read book Genetically Engineered Crops written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2017-01-28 with total page 607 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genetically engineered (GE) crops were first introduced commercially in the 1990s. After two decades of production, some groups and individuals remain critical of the technology based on their concerns about possible adverse effects on human health, the environment, and ethical considerations. At the same time, others are concerned that the technology is not reaching its potential to improve human health and the environment because of stringent regulations and reduced public funding to develop products offering more benefits to society. While the debate about these and other questions related to the genetic engineering techniques of the first 20 years goes on, emerging genetic-engineering technologies are adding new complexities to the conversation. Genetically Engineered Crops builds on previous related Academies reports published between 1987 and 2010 by undertaking a retrospective examination of the purported positive and adverse effects of GE crops and to anticipate what emerging genetic-engineering technologies hold for the future. This report indicates where there are uncertainties about the economic, agronomic, health, safety, or other impacts of GE crops and food, and makes recommendations to fill gaps in safety assessments, increase regulatory clarity, and improve innovations in and access to GE technology.
Book Synopsis Pesticidal Plants by : Philip C. Stevenson
Download or read book Pesticidal Plants written by Philip C. Stevenson and published by MDPI. This book was released on 2020-05-27 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: The global biodiversity and climate emergencies demand transformative changes to human activities. For example, food production relies on synthetic, industrial and non-sustainable products for managing pests, weeds and diseases of crops. Sustainable farming requires approaches to managing these agricultural constraints that are more environmentally benign and work with rather than against nature. Increasing pressure on synthetic products has reinvigorated efforts to identify alternative pest management options, including plant-based solutions that are environmentally benign and can be tailored to different farmers’ needs, from commercial to small holder and subsistence farming. Botanical insecticides and pesticidal plants can offer a novel, effective and more sustainable alternative to synthetic products for controlling pests, diseases and weeds. This Special Issue reviews and reports the latest developments in plant-based pesticides from identification of bioactive plant chemicals, mechanisms of activity and validation of their use in horticulture and disease vector control. Other work reports applications in rice weeds, combination biopesticides and how chemistry varies spatially and influences the effectiveness of botanicals in different locations. Three reviews assess wider questions around the potential of plant-based pest management to address the global challenges of new, invasive and established crop pests and as-yet underexploited pesticidal plants.
Book Synopsis Ecologically Based Pest Management by : National Research Council
Download or read book Ecologically Based Pest Management written by National Research Council and published by National Academies Press. This book was released on 1996-03-21 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: Widespread use of broad-spectrum chemical pesticides has revolutionized pest management. But there is growing concern about environmental contamination and human health risksâ€"and continuing frustration over the ability of pests to develop resistance to pesticides. In Ecologically Based Pest Management, an expert committee advocates the sweeping adoption of ecologically based pest management (EBPM) that promotes both agricultural productivity and a balanced ecosystem. This volume offers a vision and strategies for creating a solid, comprehensive knowledge base to support a pest management system that incorporates ecosystem processes supplemented by a continuum of inputsâ€"biological organisms, products, cultivars, and cultural controls. The result will be safe, profitable, and durable pest management strategies. The book evaluates the feasibility of EBPM and examines how best to move beyond optimal examples into the mainstream of agriculture. The committee stresses the need for information, identifies research priorities in the biological as well as socioeconomic realm, and suggests institutional structures for a multidisciplinary research effort. Ecologically Based Pest Management addresses risk assessment, risk management, and public oversight of EBPM. The volume also overviews the history of pest managementâ€"from the use of sulfur compounds in 1000 B.C. to the emergence of transgenic technology. Ecologically Based Pest Management will be vitally important to the agrichemical industry; policymakers, regulators, and scientists in agriculture and forestry; biologists, researchers, and environmental advocates; and interested growers.
Book Synopsis Insect Resistance Management by : David W. Onstad
Download or read book Insect Resistance Management written by David W. Onstad and published by Academic Press. This book was released on 2013-10-08 with total page 561 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neither pest management nor resistance management can occur with only an understanding of pest biology. For years, entomologists have understood, with their use of economic thresholds, that at least a minimal use of economics was necessary for proper integrated pest management. IRM is even more complicated and dependent on understanding and using socioeconomic factors. The new edition of Insect Resistance Management addresses these issues and much more. Many new ideas, facts and case studies have been developed since the previous edition of Insect Resistance Management published. With a new chapter focusing on Resistance Mechanisms Related to Plant-incorporated Toxins and heavily expanded revisions of several existing chapters, this new volume will be an invaluable resource for IRM researchers, practitioners, professors and advanced students. Authors in this edition include professors at major universities, leaders in the chemical and seed industry, evolutionary biologists and active IRM practitioners. This revision also contains more information about IRM outside North America, and a modeling chapter contains a large new section on uncertainty analysis, a subject recently emphasized by the U.S. Environmental Protection Agency. The final chapter contains a section on insecticidal seed treatments. No other book has the breadth of coverage of Insect Resistance Management, 2e. It not only covers molecular to economic issues, but also transgenic crops, seed treatments and other pest management tactics such as crop rotation. Major themes continuing from the first edition include the importance of using IRM in the integrated pest management paradigm, the need to study and account for pest behavior, and the influence of human behavior and decision making in IRM. - Provides insights from the history of insect resistance management (IRM) to the latest science - Includes contributions from experts on ecological aspects of IRM, molecular and population genetics, economics, and IRM social issues - Offers biochemistry and molecular genetics of insecticides presented with an emphasis on recent research - Encourages scientists and stakeholders to implement and coordinate strategies based on local social conditions

Book Synopsis The Side Effects of Insecticides on Insects and the Adaptation Mechanisms of Insects to Insecticides by : Youhui Gong
Download or read book The Side Effects of Insecticides on Insects and the Adaptation Mechanisms of Insects to Insecticides written by Youhui Gong and published by Frontiers Media SA. This book was released on 2023-10-20 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: Insecticides have played a major role in the management of agricultural and medical insect pests since their first application in pest control. The impacts of insecticide on the environment, as well as on organisms in ecosystems, have been addressed for decades. On the one hand, the side effects of insecticides on pollinating insects, natural predators and nontarget insects, can cause imbalances/disruption in ecosystems, and resurgence of target pests, which eventually leads to agricultural production losses. On the other hand, as one of the most successful groups of animals, insects have evolved a wide range of adaptive strategies that allow them to live in almost every habitat on earth, survive and reproduce even when subjected to chemical stresses such as natural plant allelochemicals and insecticides. Outbreaks of pests following insecticide application owing to hormesis effects and evolution of insecticide resistance in insects threatens the sustainability of insecticides employed as the most effective measure for control of agricultural and medical pests.
Book Synopsis Arthropod Management and Landscape Considerations in Large-Scale Agroecosystems by : Michael J. Brewer
Download or read book Arthropod Management and Landscape Considerations in Large-Scale Agroecosystems written by Michael J. Brewer and published by CABI. This book was released on 2024-08-16 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: For large-scale agroecosystems, patterns of pest population increases (graded increases or abrupt outbreaks) and declines (graded suppression or abrupt crashes) vary considerably and are influenced by factors within crop fields and across broader landscape scales. Better understanding of pest population dynamics and the implications of spatial interactions on the function and development of pest management approaches are the main themes of this important book. The book builds from a 60+ year history of field-based pest management by focusing on the drivers of pest management in large-scale agroecosystems and the landscape-scale processes that affect these drivers and contribute to variation in pest outbreaks and suppression. These drivers include abiotic and biotic influences such as weather, spatial composition and arrangement of landscape elements, and widely applied managed inputs such as planting and crop rotation schedules, crop varietal selection, and land and soil conservation efforts. The book introduces general concepts, opportunities, and challenges of arthropod management in large-scale agroecosystems. The book is essential reading for researchers in applied entomology and ecology and for pest management practitioners.
