Book Description
For many agricultural crops, bees play a vital role as pollinators, and this book discusses the interplay among bees, agriculture, and the environment. Although honey bees are well recognized as pollinators, managed bumble bees and solitary bees are also critical for the successful pollination of certain crops, while wild bees provide a free service. As bees liberally pass pollen from one plant to the next, they also impact the broader ecosystem, and not always to the benefit of humankind. Bees can enhance the unintentional spread of genes from genetically engineered plants, and may increase the spread of invasive weeds. Conversely, genetically engineered plants can impact pollinators, and invasive weeds can supply new sources of food for these insects. Bees' flower-visiting activities also can be exploited to help spread biological control agents that control crop pests, and they are important for native plant reproduction. Managing bees for pollination is complex and the factors that must be taken into consideration are treated here, including bee natural history, physiology, pathology, and behavior. Furthermore, transporting bees from native ranges to new areas for pollination services can be controversial, and needs to be done only after assuring that it will not disrupt various ecosystems. Even though bees are small, unobtrusive creatures, they play large roles in the ecosystem. The connection between bees and humankind also is symbolic of a broader interconnection between humans and the natural world.

Book Description
Mass Production of Beneficial Organisms: Invertebrates and Entomopathogens, Second Edition explores the latest advancements and technologies for large-scale rearing and manipulation of natural enemies while presenting ways of improving success rate, predictability of biological control procedures, and demonstrating their safe and effective use. Organized into three sections, Parasitoids and Predators, Pathogens, and Invertebrates for Other Applications, this second edition contains important new information on production technology of predatory mites and hymenopteran parasitoids for biological control, application of insects in the food industry and production methods of insects for feed and food, and production of bumble bees for pollination.Beneficial organisms include not only insect predators and parasitoids, but also mite predators, nematodes, fungi, bacteria and viruses. In the past two decades, tremendous advances have been achieved in developing technology for producing these organisms. Despite that and the globally growing research and interest in biological control and biotechnology applications, commercialization of these technologies is still in progress. This is an essential reference and teaching tool for researchers in developed and developing countries working to produce "natural enemies in biological control and integrated pest management programs. - Highlights the most advanced and current techniques for mass production of beneficial organisms and methods of evaluation and quality assessment - Presents methods for developing artificial diets and reviews the evaluation and assurance of the quality of mass-produced arthropods - Provides an outlook of the growing industry of insects as food and feed and describes methods for mass producing the most important insect species used as animal food and food ingredients
