The European species of Omphale are revised, including 37 species, of which 11 are new. All species are described, thoroughly illustrated, and included in gender-specific identification keys. Two new morphological character-sets are introduced for the classification, male genitalia and wing interference patterns (WIPs). Both sets are used to identify species, and the former is also useful for classification of species-groups. Hosts are known for 14 species and all are primary endoparasitoids of immature stages of gall-midges (Diptera: Cecidomyiidae). Host preferences are unique for each species, suggesting host specialization as a driving force for speciation. Several of the species are known only from females or have a strong female-biased sex-ratio, indicating thelytokous parthenogenesis. Distributional data point to a pan-European distribution for most species. New synonyms and combinations affect the nomenclature in subfamily Entedoninae.

Annotated Keys To The Genera Of Nearctic Chalcidoidea Hymenoptera written by Gary A. P. Gibson and has been published by NRC Research Press this book supported file pdf, txt, epub, kindle and other format this book has been release on 1997 with Science categories.
This publication presents illustrated keys to the 19 families and 706 described genera of Chalcidoidea known to occur in the Nearctic region (minimally America north of Mexico, but also including those areas of Mexico generally considered as having a Nearctic insect fauna). The first three chapters provide an introduction to this superfamily of wasps, most of whose members are parasites of other insects; a review of chalcidoid morphology as related to terms used in the keys & diagnoses; and an overview of the superfamily, including a 41 couplet key to families. Each of the remaining 19 chapters reviews one family & includes sections on recognition, systematics & relationships, biology, literature, an annotated key to the Nearctic genera, and for larger families an index to genera based on couplet number. Over 1,800 line drawings & electron micrographs illustrate the keys. Annotations include references to existing keys to species, estimated number of species, and known distribution & host range in the region.

The superfamily Chalcidoidea (Insecta, Hymenoptera) contains in excess of 26,000 described species worldwide, but with an estimated total diversity of more than 500,000 species the vast majority of species have yet to be discovered and described. Most chalcidoid species are parasitoids of hosts in at least 12 different insect orders, attacking the egg, larval or pupal stages, though phytophagy and other life cycles and hosts are known. Iran is the 18th largest country in the world and has a rich and diverse insect fauna, including Chalcidoidea. It is extremely interesting from a biogeographic point of view, and a paradise for an entomologist. This book summarizes the results of all prior research concerning species diversity of Iranian Chalcidoidea, including host records and distribution records by province in Iran as well as world distribution by country for 1,351 species of Chalcidoidea recorded from Iran through the end of 2019.

Chrysomelidae, along with Curculionidae and Bruchidae, are the most important phytophagous Coleoptera. At least 37,000 species of leaf beetles belonging to 19 subfamilies have now been described, and more probably remain to be discovered, especially in the tropics. Many species are familiar agricultural pests. The Colorado potato beetle, the cereal beetle, flea beetle and the corn root worms are but a few of the well known pests. Because of the economic importance and biological diversity, chrysomelids are an important taxonomic group for scientific inquiry. This book is divided into eight parts, entitled palaeontology, larvae and larval biology, trophic selection, genetics and evolution defence mechanisms, anatomy and reproduction, pathogens and natural enemies, and general studies in biology. The biologies of agricultural and forestry pests, Leptinotarsa, Plagiodera, Entomoscelis, Paropsis, Mecistomela and Aspidomorpha are dealt with in detail. Others, such as Timarcha and those in the poorly known Megalopodinae, are covered in Part VIII. In this volume the American, European, Asian and Australian fauna occupy the greatest part. This volume, together with Biology of Chrysomelidae (1988), provides a comprehensive coverage and helps to complete the picture of chrysomelid biology.

Oilseed rape is a major arable crop in both Europe and North America. It is attacked by unique complexes of insect pests still largely controlled through the application of chemical insecticides. Crop management systems for the future must combine sustainability with environmental acceptability to satisfy both social and economic demands. This book, in its 17 chapters each led by a world expert, reviews research progress towards developing integrated pest management systems for the crop that enhance conservation biocontrol. This approach is particularly timely because of the development in Europe of insecticide resistance in the pollen beetle, a major pest of the crop. The past decade has seen considerable progress in our knowledge of the parasitoids and predators that contribute to biocontrol, of their distribution patterns, and their behavioural ecology, both within and without the crop. There is potential for natural enemy conservation through modification of within-field crop husbandry practices, as well as, on the landscape scale, through habitat manipulation to encourage vegetational diversity. This book will prove invaluable as a text for researchers, university teachers, graduate scientists, extension workers and growers involved in integrated pest management.

Soft Scale Insects is intended to be a further step towards providing comprehensive information on soft scale insects. Four or five decades ago, entomologists embarking on a study on soft scale insects would have encountered a scarcity of general text books or comprehensive treatise of the family, as a starting point for their research. At the time, the available knowledge and data were either scattered among numerous articles or regional monographs or were in obsolete books. It is hoped that this volume will cover almost the entire spectrum of the knowledge on the soft scale insect family, Coccidae. This book comprises six chapters and begins by discussing the natural enemies of soft scale insects, such as pathogens like entomopathogenic fungi; predators like coccineilidae and other coleoptera; and parasitoids like encyrtidae. It then discusses issues of damage and control, including pest status of soft scale insects and coccid pests of important crops. This book will be of interest to entomologists, horticulturists, zoologists, biologists, and those involved in general agricultural research.
