Book Description
This publication treats the species of Trialeurodes known from North America. In this region the genus is of particular interest because of its wide distribution, the number and diversity of its food plants, and the injuriousness of certain species. It is the largest aleyrodid genus known on the continent, and all species now known in the Nearctic Region presumably are indigenous to it or are Neotropical species whose northern limits extend into that Region. Characteristics of interest are modifications in papillae and in the vasiform orifice exhibited by some its members, and also the unusual parthenogenetic behavior of one of them.

Book Description
Excerpt from The North American Species of Whiteflies of the Genus Trialeurodes This organ is present in other aleyrodid genera, and its presence appears to be satisfactory for separating the sexes throughout the family.

Book Description
Bemisia tabaci (Gennedius) has distinguished itself from the more than 1,000 whitefly species in the world by its adaptability, persistence and potential to damage a wide range of agricultural and horticultural crops in all six of the world’s inhabited continents. B. tabaci inflicts plant damage through direct feeding, inducement of plant disorders, vectoring of plant viruses and excretion of honeydew. This book collates multiple aspects of the pest ranging from basic to applied science and molecular to landscape levels of investigation. Experts in multiple disciplines provide broad, but detailed summaries and discussion of taxonomy, genetics, anatomy, morphology, physiology, behavior, ecology, symbiotic relationships, virus vector associations and various tactics for integrated management of this pest insect. The book is focused primarily on progress during the last 10-15 years and is directed at workers in the field as well as the informed professional who may not necessarily specialize in whitefly research. The book is unique in providing broad coverage in relatively few chapters by recognized experts that highlight the state-of-the-art in our understanding of this fascinating but troublesome cosmopolitan pest.

Book Description
Written by experts in the fields of insect pest genetics, the genetics of biological control organisms, and the application of biological control, this book provides the first up-to-date summary of the genetic literature on the genetics of arthropod biological control agents. It identifies successful programs and also gaps and needs in research, research constraints, and possible research approaches in this important field of pest control. The power and applicability of new genetic and molecular biology methods have created new and exciting possibilities to greatly improve the effectiveness of traditional biological control programs. This book provides essential information about the state-of-the-art application of these new methods. It explains how biological control procedures can be improved, covers methods for selecting pesticide-resistant strains of natural enemies, and looks at methods for maintaining genetic diversity and quality control during the rearing of biological control agents in the laboratory. The book also provides information regarding the application of powerful PCR methods for taxonomic identification of strains and species of biocontrol agents.
