Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

This summary of the results of chromosomal analysis of various groups of parasitic wasps will be essential reading for those working in the field. It is the second edition of a monograph that was first published in Russian, and has been substantially updated with new data, conclusions and references. The goal of this ground-breaking work is to document the author’s study of the karyotype structure and chromosomal evolution of parasitic Hymenoptera. It also interprets the results obtained, from both routine and differential chromosome staining, for systematic and phylogenetic purposes. Despite the huge importance of parasitic wasps, many problems of their taxonomy remain insufficiently studied. This is a situation that needs rectifying, as Hymenoptera are one of the largest and most taxonomically complicated groups of insects and they play a very important role in food chains as parasitoids of the overwhelming majority of insects and other arthropods. Parasitic wasps attack many pests of agriculture and forestry as well as certain beneficial insects. In addition, some secondarily phytophagous Hymenoptera damage certain cultivated plants. The renowned entomologist and author of this volume, Vladimir Gokhman, has himself developed a particular technique for obtaining chromosomal preparations from adult parasitic wasps. This allowed the inclusion of a wide range of those insects into the study. The karyotypic features of the majority of superfamilies and families as well as many lower taxa of parasitic Hymenoptera are listed, while the plesiomorphic and apomorphic character states of chromosome sets of parasitic wasps are revealed. The structural features of karyotypes used for identifying and discriminating sibling species and similar forms are shown, as are the data on chromosome sets of about 400 species of parasitic Hymenoptera (including more than 200 micrographs). Also included is a comprehensive phylogenetic and taxonomic analysis of karyotypic information. This book is unique because it demonstrates a range of karyotypic data for an insect group that seemed unattainable in this respect not so long ago. Rich in new facts, techniques and ideas, it will be of use to all those interested in karyology and Hymenoptera.

Braconidae of the Middle East (Hymenoptera): Taxonomy, Distribution, Biology, and Biocontrol Benefits of Parasitoid Wasps provides the latest and most comprehensive knowledge of parasitoid wasp species. The highest concentration of these species is native to, or found in, the Middle East. This book covers the distribution of these species across the Palearctic region and their widespread global benefits as natural biocontrol agents. Each chapter covers a braconid subfamily, providing introductory information on its biology and phylogeny, total number of species, global distribution, and how they can be used to control pests and invasive insect species. In addition, this book discusses the importance of integrated pest management, specifically how Braconidae can be used for one-time or repeated introduction to natural enemies in suppressing pest populations. Finally, each chapter offers an illustrative key for readers to visualize and identify each species.
