The Business of Plant Breeding is the result of a study on demand-led plant variety design for markets in Africa, sharing best practices from private and public sector breeding programmes worldwide that are applicable to improving tropical crops in Africa. Beginning with an overview of the principles of demand-led plant breeding, the book then discusses aspects such as understanding the demands of clients and markets in rural and urban areas, foresight in setting product profiles and breeding targets, and determining breeding strategy and stage plans. It also covers measuring success and making the business case for future investments in breeding programmes that will deliver new varieties to meet market demands. The book: - Brings together the experience of plant breeders around the world, representing universities, national plant breeding programmes, regional and international agricultural research institutes, and private seed companies, showcasing how to respond to changing market demands; - Provides educational resource materials within each chapter; - Includes templates for use as planning tools by plant breeding programs for determining priority traits that meet market demands. An important read for professionals and students of plant breeding and genetics, this book is also a useful resource for anyone interested in developing and disseminating new, market-led technologies to increase productivity and profitability in tropical agriculture. The study was sponsored by the Australian Centre for International Agricultural Research, the Crawford Fund and the Syngenta Foundation for Sustainable Agriculture, and managed by the University of Queensland.

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
