Download or read book Revision of the European species of Omphale Haliday Hymenoptera Chalcidoidea Eulophidae written by Christer Hansson and published by PenSoft Publishers LTD. This book was released on 2012-10-25 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Annotated Keys to the Genera of Nearctic Chalcidoidea Hymenoptera written by Gary A. P. Gibson and published by NRC Research Press. This book was released on 1997 with total page 814 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Biocontrol Based Integrated Management of Oilseed Rape Pests written by Ingrid H. Williams and published by Springer Science & Business Media. This book was released on 2010-06-16 with total page 461 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
