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.
Download or read book Sustainable Management of Invasive Pests in Africa written by Saliou Niassy and published by Springer Nature. This book was released on 2020-07-13 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invasive species, generally, affect economically important crops, thus affecting the livelihoods of millions of people along crop value chains. Typically, invasive species have high migratory capabilities and, because of plant material exchanges made during trade, they cannot be contained by one country. Usually, African countries react after a pest has invaded and established itself in the country, making the cost of mitigating the pest even more expensive. This book presents a pan-African view of the impacts of invasive insect pests on agriculture and of how invasive species impact on productivity in Africa. It not only describes their importance, but also presents a diversity of research findings in the field, ranging from the use of early warning and monitoring systems for quarantine purposes, agricultural extension, all the way to control strategies. The IPM arsenal presented in this book includes the use of botanical bioactive compounds, semiochemicals, resistant varieties, biological control agents such as entomopathogens, endophytes, predators, and natural enemies. Aspects of technology transfer strategies, regional coordination, and farmers’ perceptions have not been overlooked, because these affect the adoption of mitigation strategies. The book also presents measures that would help agricultural research services to estimate the damage and take actions for preparedness and readiness to face invasive insect pests. This starts with a basic knowledge of taxonomy to enable concerned persons to describe the insects and the vast inventory of affected crops. Physiological and ecological aspects of invasive pests are strongly highlighted to strengthen Integrated Pest Management Strategies. The threat of invasive species will remain permanent; therefore, the book encourages knowledge exchange and collaboration between researchers and scientists on the continent, while encouraging the establishment of a platform or a fund for preparedness and rapid response.

Download or read book Reforming Africa s Institutions written by Steve Kayizzi-Mugerwa and published by . This book was released on 2003 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is not a single African country that did not attempt public sector reforms in the 1990s. Governments no longer see themselves as sole suppliers of social services, frequently opting for partnerships with the private sector. Efficiency and choice have entered the language of the planning and implementation units of Africa's line ministries, while privatization is no longer the controversial subject it was a decade ago. There have also been moves towards more open and democratic governments. Reforming Africa's Institutions looks at the extent to which reforms undertaken in Sub-Saharan Africa in recent years have enhanced institutional capacities across the breadth of government. To what extent have reforms been internalized and defended by governments? The authors also look specifically at the impact of public sector reforms on these economies and pose the question whether 'ownership can be attained when countries continue to be heavily dependent on external support. The volume is presented in three parts. The first focuses on the issue of reform ownership; on the issues of governance, the political economy of reform ownership, and the contradictions inherent in using aid as an instrument for enhancing domestic reform ownership. Part two examines the nature of incentives in the African civil service and the reforms undertaken in recent years to raise public sector efficiency in Africa. The third part discusses issues related to institutional capabilities in Africa and how they have been affected by the reforms undertaken in the 1990s, including privatization and movement towards political pluralism.
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.
Download or read book Mitochondrial DNA Sequence Variation in the African Armyworm Spodoptera Exempta Lepidoptera Noctuidae written by Amna E. Elguzouli and published by . This book was released on 2013 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: The African armyworm remains problematic as a serious pest of cereals in sub-Sahara Africa. The population genetic structure of African armyworms was investigated to better understand the species' population dynamics and the extent to which the two major outbreak areas in East Africa and Southern Africa are linked by gene flow. Armyworm population dynamics in the species' northern range appears to be decoupled from its population dynamics in the south. This implies that this pest's control strategies need to be region specific. However, this study had only two sampling points. A finer scale, multipoint sampling throughout the species geographic range, preferably during multiple years, is required in order to answer this question unambiguously. This would assist in developing an outbreak early warning system and in determining if multi-region control strategy is warranted. A significant proportion of the divergence between the two sampling localities is attributable to two rare but highly divergent haplotypes. The possibility of these two haplotypes belonging to another, as yet unknown moth species, has been discussed. In addition to the above insights, this study has assessed the utility of the large number of universal mtDNA primers in the study of armyworm population genetics.
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 Made in Africa written by Carol Newman and published by Brookings Institution Press. This book was released on 2016-02-23 with total page 315 pages. Available in PDF, EPUB and Kindle. Book excerpt: Why is there so little industry in Africa? Over the past forty years, industry has moved from the developed to the developing world, yet Africa’s share of global manufacturing has fallen from about 3 percent in 1970 to less than 2 percent in 2014. Industry is important to low-income countries. It is good for economic growth, job creation, and poverty reduction. Made in Africa: Learning to Compete in Industry outlines a new strategy to help African industry compete in global markets. This book draws on case studies and econometric and qualitative research from Africa and emerging Asia to understand what drives firm-level competitiveness in low-income countries. The results show that while traditional concerns such as infrastructure, skills, and the regulatory environment are important, they alone will not be sufficient for Africa to industrialize. The book also addresses how industrialization strategies will need to adapt to the region’s growing resource abundance.
