Polyembryonic Insects


Book Description

This book provides an overview of our current understanding of polyembryony in insects. The study of polyembronic insects has advanced considerably over the last several decades.The book shows the exciting potential of polyembryonic insects and their impact on life sciences. It describes the mechanisms of polyembryogenesis; tissue-compatible invasion of the host, which is the first case of compatible cellular interaction between phylogenetically distant organisms without rejection; the sex differences in defense; and the environmental regulation of caste structure. The first book devoted to polyembryony in insects, it draws on the author’s research on polyembryonic wasps from 1990 to the present day, covering various topics such as polyembryogenesis in vitro, host-parasite interaction, sex differences in soldier function/humoral toxic factor, and the transcription analysis of polyembryogenesis.It is intended not only for researchers in the field of entomology, parasitology, ontogeny, reproductive biology, developmental biology, sociobiology, and evolutionary developmental biology (Evo-Devo), but also for postgraduate students in these fields.




Parasites and Pathogens


Book Description

When Nancy Beckage and I first met in Lynn Riddiford's laboratory at the University of Washington in the mid 1970s, the fields of parasitology, behavior, and endocrinology were thriving and far-flung--disciplines in no serious danger of intersecting. There were rumors that they might have some common ground: Behavioural Aspects of Parasite Transmission (Canning and Wright, 1972) had just emerged, with exciting news not only of the way parasites themselves behave, but also of Machiavellian worms that caused intermediate hosts to shift fundamental responses to light and disturbance, becoming in the process more vulnerable to predation by the next host (Holmes and Bethel, 1972). Meanwhile, biologists such as Miriam Rothschild (see Dedication), G. B. Solomon (1969), and Lynn Riddiford herself (1975) had suggested that the endocrinological rami of parasitism might be subtle and pervasive. In general, however, para fications sites were viewed as aberrant organisms, perhaps good for a few just-so stories prior to turning our attention once again to real animals. In the decade that followed, Pauline Lawrence (1986a,b), Davy Jones (Jones et al. , 1986), Nancy Beckage (Beckage, 1985; Beckage and Templeton, 1986), and others, including many in this volume, left no doubt that the host-parasite combination in insect systems was physiologically distinct from its unparasitized counterpart in ways that went beyond gross pathology.










Field Crop Arthropod Pests of Economic Importance


Book Description

Field Crop Arthropod Pests of Economic Importance presents detailed descriptions of the biology and ecology of important arthropod pest of selected global field crops. Standard management options for insect pest control on crops include biological, non-chemical, and chemical approaches. However, because agricultural crops face a wide range of insect pests throughout the year, it can prove difficult to find a simple solution to insect pest control in many, if not most, cropping systems. A whole-farm or integrated pest management approach combines cultural, natural, and chemical controls to maintain insect pest populations below levels that cause economic damage to the crop. This practice requires accurate species identification and thorough knowledge of the biology and ecology of the target organism. Integration and effective use of various control components is often enhanced when the target organism is correctly identified, and its biology and ecology are known. This book provides a key resource toward that identification and understanding. Students and professionals in agronomy, insect detection and survey, and economic entomology will find the book a valuable learning aid and resource tool. - Includes insect synonyms, common names, and geographic distribution - Provides information on natural enemies - Is thoroughly referenced for future research







Current Topics in Developmental Biology


Book Description

Volume 35 proves to be essential reading for anyone interested in reactions between retinoid signaling pathways and the genes regulating cell proliferation/survival, developmentally-regulated changes in the nuclear envelope, the developmental roles of the EGFR, or ErbB family, the correspondence between phylogeny and life history in polyembryonic insect development, control of cadherin function by extracellular signals, the importance of the Spemann organizer for neural induction, and the study of signal transduction in Drosophila melanogaster.
