Buch. Condizione: Neu. Druck auf Anfrage Neuware - Printed after ordering - 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.…

Taschenbuch. Condizione: Neu. Druck auf Anfrage Neuware - Printed after ordering - Horticultural sector presents many opportunities for economic development and improving livelihood of growers but several factors constrain production and limit the potential for trade of fruits and vegetables. Tephritid fruit flies constitute a major constraint. They cause enormous losses through direct feeding damage and loss of market opportunities through imposition of quarantine restrictions by importing countries to prevent entry and their establishment. In Africa, several native (Ceratitis and Dacus spp) and exotic (Bactrocera and Zeugodacus spp.) species inflict considerable losses to horticulture causing losses ranging from 30-90%. Over the past 10 years of R&D, extensive information has been generated on bioecology and management of several native and exotic fruit flies in Africa. While several specific reviews have addressed various aspects of the biology, ecology and management of economically important tephritid fruit flies; coverage of African native species has beenlimited largely to Bactrocera oleae and Ceratitis capitata - which are not economically important species in many Africa countries. Indeed, no book exist that have explicitly addressed economically important African fruit flies and none of the various reviews, have specifically focused on the status of the bioecology, economic impact and management of exotic and native fruit flies - including several potentially invasive Dacus species attacking vegetables - in Africa. This book consolidates this status of knowledge and socio-economic impact of various intervention techniques that are currently being applied across Africa. The timing of the book is especially pertinent due to the changing fruit fly landscape in Africa - caused by arrivals of the highly destructive alien invasives (Bactrocera dorsalis, B. zonata, and B. latifrons) - and the priorities African countries have placed recently on export of fruits and vegetables to international markets. This is an important reference material for researchers, academics and students that are keen at improving horticulture and enhancing food and nutrition security in Africa and beyond. …

Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - This work established the temperature range for development and survival of Bactrocera invadens, an alien invasive fruit fly species of Asian origin. The optimal temperature for survival was found to be 25°C while 35°C was the most lethal temperature. The insect infested fourteen plant species particularly mango and citrus and the wild plants marula plum and tropical almond. In host preference studies, mango and banana were found to be the most preferred host plants. The spatial and temporal population dynamics revealed that the relative abundance index (RAI) of mango pests was in the order B. invadens C. cosyra C. capitata and that mango fruits that fall to the ground serve as a major breeding site and may be a reservoir of non-immigrant B. invadens population in mango orchards. Interspecific competition studies demonstrated that the mechanisms contributing to the displacement of C. cosyra by B. invadens may be associated with intricate interactions between resource pre-emption and fluctuations in temperature in mango agroecosystems.…
