Book Description
Excerpt from A Study in Insect Parasitism: A Consideration of the Parasites of the White-Marked Tussock Moth, With an Account of Their Habits and Interrelations, and With Descriptions of New Species Many observations are recorded which show the prominent part which parasites take in the reduction of an insect which under favor able conditions has exceeded its normal bounds in respect to numbers. Such constant struggles between species in the apparent effort to pre serve a just balance are met with by every observer in the course of nearly every season's observations. The writer has, however, always desired an opportunity to study the exact details of such a struggle upon a large scale, and this opportunity was afforded in this instance.

Book Description
Both volumes of Parasites and Pathogens of Insects provide in-depth coverage of the interface between insect parasites and pathogens and hosts, and explore the relationships between these partners. They emphasize biochemical and molecular interactions, basic biology, and the roles of hormones, receptors, and other cellular components in modulating interactions between host insects and attacking agents. These topics also are assessed in relation to biotechnology and biological control.In the short term, these volumes fill a void in current literature by emphasizing basic interactions at the biochemical and molecular levels. In the long term, these interactions may provide avenues for exploitation to enhance the rate of "beneficial" parasitism or to reduce the rates of disease transmission and infection of vertebrate hosts. - Presents the latest information on insect parasites and pathogens - Describes biochemical and molecular host-parasite and host-pathogen relationships - Covers mechanisms of insect pathogenicity and resistance - Provides exceptional breadth of coverage and authoritative reviews - Special topics - Transposable elements in insect pathogens - Co-evolution and gene transfer between hosts and invaders - Biological control

Book Description
This two-volume edited book highlights and reviews the potential of the fossil record to calibrate the origin and evolution of parasitism, and the techniques to understand the development of parasite-host associations and their relationships with environmental and ecological changes. The book deploys a broad and comprehensive approach, aimed at understanding the origins and developments of various parasite groups, in order to provide a wider evolutionary picture of parasitism as part of biodiversity. This is in contrast to most contributions by parasitologists in the literature that focus on circular lines of evidence, such as extrapolating from current host associations or distributions, to estimate constraints on the timing of the origin and evolution of various parasite groups. This approach is narrow and fails to provide the wider evolutionary picture of parasitism on, and as part of, biodiversity. Volume one focuses on identifying parasitism in the fossil record, and sheds light on the distribution and ecological importance of parasite-host interactions over time. In order to better understand the evolutionary history of parasites and their relationship with changes in the environment, emphasis is given to viruses, bacteria, protists and multicellular eukaryotes as parasites. Particular attention is given to fungi and metazoans such as bivalves, cnidarians, crustaceans, gastropods, helminths, insects, mites and ticks as parasites. Researchers, specifically evolutionary (paleo)biologists and parasitologists, interested in the evolutionary history of parasite-host interactions as well as students studying parasitism will find this book appealing.

Book Description
Written by a team of leading international specialists, Behavioral Ecology of Insect Parasitoids examines the optimal behaviors that parasitoids exhibit in order to maximize long term offspring production. It is an essential reference for research scientists and students studying these fascinating insects or for anyone involved in using parasitoids in biological control programs. Reviews topical issues, including cutting edge research on parasitoid decision making and the implications for biological control Explores applications in other fields, provides information on the latest research methods, and includes helpful case studies and statistical tools Creates a deeper understanding of the link between behavioural strategies and host mortality, resulting in more efficient selective pest management programs “Overall, this is a fascinating volume that provides a significant contribution to the literature on parasitoid insects. It goes a long way toward providing insights into numerous aspects of parasitoid behavior and will stimulate a diversity of future projects, something that should be the goal of any such text. I highly recommend Wajnberg et al. for all of those working on the biology or evolution of parasitoids.” Palaios 2009
