Book Description
Diapriids (Hymenoptera: Diapriidae) are small parasitic wasps. Though found throughout the world they are relatively unknown. A framework for advancing diapriid systematics is developed by introducing a new web-based application/database capable of storing a broad range of systematic data, and the first molecular phylogeny specifically focused at examining intrafamilial relationships. In addition to these efforts, a description of a new taxon is provided. Several advantages of digital description, including linking descriptions to an ontology of morphological terms, are highlighted. The functionality of the database is further illustrated in the production of a catalog of diapriid host associations. The hosts database currently holds over 450 association records, for over 500 named taxa (parasitoids and hosts), and over 180 references. Diapriids are found to be primarily endoparasitoids of Diptera emerging from the host pupa. Phylogenetic inference for a molecular dataset of 28S and 18S rRNA sequence data, derived from a diverse selection of diapriids, is accomplished with a new suite of tools developed for handling complex rRNA datasets. Several parsimony-based methodologies, including an alignment-free method of analyzing multiple sequences, are reviewed and applied using the new software tools. Diapriid phylogenetic relationships are shown to be broadly congruent with existing morphology-based classifications. Methods for analyzing typically excluded sequence data are shown to recover phylogenetic signal that would otherwise be lost and the alignment-free method performed remarkably well in this regard. Empirically, phylogenetic approaches that incorporate structural data were not notably different than those that did not.

Book Description
This issue celebrates the 75th birthday ofÿ Dr. Lubom?r Masner, a source of knowledge, enthusiasm, and inspiration for systematic entomologists in all fields, but especially for students of Hymenoptera. His unflagging dedication to the study of the parasitoid wasps of the superfamilies Proctotrupoidea, Platygastroidea, and Ceraphronoidea has completely transformed our understanding of the richness and evolutionaryÿ history of these insects. His zeal and innovation in collecting have not only dramatically enhanced the basis for our understanding of hymenopteran diversity, but also contributed to the development of the Canadian National Collection of Insects into one of the premiere systematic entomology research institutions in the world. Twenty-six authors have contributed to this volume in 17 papers on the systematics of the families Braconidae, Ceraphronidae, Chalcididae, Eucharitidae, Eupelmidae, Eurytomidae, Figitidae, Mymaridae, Platygastridae, Vespidae, and Xiphydriidae. Six new genera and 33 new species are described, encompassing fossil material as well as species from the Neotropical, Afrotropical, Oriental, and Australasian regions. A short biography of Dr. Masner is accompanied by a bibliography of his scientific papers, a list of taxa he has described over 55 years of research, and a list of taxa named in his honor.

Book Description
Fruit fly (Diptera: Tephritidae) pests have a profound impact on horticultural production and economy of many countries. It is fundamental to understand their biology and evaluate methods for their suppression, containment, or eradication. Area-Wide Management of Fruit Fly Pests comprises contributions from scientists from around the world on several species of tephritids working on diverse subjects with a focus on area-wide management of these pests. The first three sections of the book explore aspects of the biology, ecology, physiology, behavior, taxonomy, and morphology of fruit flies. The next two sections provide evidence on the efficacy of attractants, risk assessment, quarantine, and post-harvest control methods. The fifth and sixth sections examine biological control methods such as the Sterile Insect Technique and the use of natural enemies of fruit flies. The seventh section focuses on area-wide integrated pest management and action programs. Finally, the eighth section examines social, economic, and policy issues of action programs aimed at involving the wider community in the control of these pests and facilitate the development of control programs. Features: Presents information on the biology of tephritid flies. Provides knowledge on the use of natural enemies of fruit flies for their biological control. Includes research results on models and diets used for the Sterile Insect Technique. Reports developments on the chemical ecology of fruit flies that contribute to make control methods more specific and efficient. Reviews subjects such as Holistic Pest Management and Area-Wide Management Programs including social, economic, and policy issues in various countries.

Book Description
This publication is the result of a course on identification of Hymenoptera given three times since 1985 at the Centre for Land and Biological Resources Research. The considerable interest in these courses indicated the need for a comprehensive identification guide to all extant families of Hymenoptera. The main emphasis is on family identification using the keys, which are complemented by family sketches. The sketches include a taxonomic diagnosis to supplement the keys, a summary of the biology, the size and distribution, and important literature references.

Book Description
Plant based biotechnology has come to represent a means of mitigating the problems of global food security in the twenty-first century. Products and processes in agriculture are increasingly becoming linked to science and cutting edge technology, to enable the engineering of what are in effect, designer plants. One of the most successful , non-chemical approaches to pest management and disease control is biological control, which seeks a solution in terms of using living organisms to regulate the incidence of pests and pathogens, providing a natural control' while still maintaining the biological balance with the ecosystem. This volume, (the first of two), addresses the different types of biocontrol for different pests, namely, crop diseases, weeds and nematodes, and details the biology of both the pest and its enemies, which is vital for efficient use of biological control. The book has numerous contributors who are authorities in their fields, and would be an asset to those who have interest in sustainable agriculture and crop productivity.
