Ecology or the relationship of organisms to their environment has in recent years developed into a major biological discipline embracing within its field other disciplines as well. In recent years tendency has been to emphasize the various aspects of ecology from the angle of ecosystem and much stress has been laid on the conservation of natural fauna and flora.The relationship between man and insects dates back since time immemorial. Insects are foes and friends and have always been the subject of interest to human beings. The part played by the insects in any ecosystem, the hazards caused by them and the interest in conserving the beneficial ones form the general theme of the work. Various ecological aspects by taking insects as key animals has been discussed and it is hoped that the book would attract wide attention of students, teachers, researchers and persons involved in environmental as well as integrated pest management.

Insect Ecology: An Ecosystem Approach, Fourth Edition, follows a hierarchical organization that begins with relatively easy-to-understand chapters on adaptive responses of insect populations to various environmental changes, disturbances, and anthropogenic activities, how insects find food and habitat resources, and how insects allocate available energy and nutrients. Chapters build on fundamental information to show how insect populations respond to changing environmental conditions, including spatial and temporal distribution of food and habitat. The next section integrates populations of interacting species within communities and how these interactions determine structure of communities over time and space. Other works in insect ecology stop there, essentially limiting presentation of insect ecology to evolutionary responses of insects to their environment, including the activities of other species. The unique aspect of this book is its four chapters on ecosystem structure and function, and how herbivores, pollinators, seed predators, and detritivores drive ecosystem dynamics and contribute to ecosystem stability. Provides the most advanced synthesis of insect ecology, with updated material throughout and new chapters Presents the roles of insects in delivery of ecosystem services and applications to pest management and conservation Features full coverage of ecosystem structure and function balanced with essential background on evolutionary aspects Includes case studies highlighting practical and theoretical applications for topics covered in each chapter

Insects represent the most abundant and diverse animal group on Earth. The number of described species is more than one million and up to ten million are estimated. Insects have one of the widest distributions in the world because they have adapted to extreme ranges of environments. Molecular ecology studies ecological processes based on the analysis of biomacromolecules, particularly DNA, RNA, and proteins, but also of low-molecular weight signal compounds. Molecular ecology uses the exciting opportunities offered by the tools of molecular biology. The book presents current entomological research, where molecular tools help to advance traditional ecological studies. Chapters include ones on insect–insect and insect–plant interactions, on mechanisms of environmental adaptation, or on the use of insect biotechnology in pest and vector control. The book helps to combine powerful methods in molecular biology with exciting issues in ecology to understand why insects became "masters of survival."

Entomology And Pest Management

ISBN : 9781478627708
Genre : Technology & Engineering
File Size : 72.56 MB

Pedigo and Rice expertly combine basic and applied entomology in this reader-friendly, pedagogically rich text. Assuming only a background in elementary biology, the authors present the major elements of general entomology before moving on to concepts in insect biology and ecology necessary for understanding insect pest management. Both theory and practice are emphasized as readers explore pertinent topics. The authors discuss pest-management issues—both preventive and curative—as aspects of applied ecology, with solutions considering environmental quality, profitability, and durability. Insect diagnostic boxes with detailed information on distribution, importance, appearance, and life cycles of particular species and groups appear throughout the text. Readers will come away with a comprehensive introduction to applied, sustainable pest management appropriate for whatever commodities they must handle.

Elements of Mathematical Ecology provides an introduction to classical and modern mathematical models, methods, and issues in population ecology. The first part of the book is devoted to simple, unstructured population models that ignore much of the variability found in natural populations for the sake of tractability. Topics covered include density dependence, bifurcations, demographic stochasticity, time delays, population interactions (predation, competition, and mutualism), and the application of optimal control theory to the management of renewable resources. The second part of this book is devoted to structured population models, covering spatially-structured population models (with a focus on reaction-diffusion models), age-structured models, and two-sex models. Suitable for upper level students and beginning researchers in ecology, mathematical biology and applied mathematics, the volume includes numerous clear line diagrams that clarify the mathematics, relevant problems thoughout the text that aid understanding, and supplementary mathematical and historical material that enrich the main text.

Chemical Ecology Of Insect Parasitoids

Insect parasitoids are a fascinating group of animals in many respects. Perhaps the most fascinating point is that these insects, in the course of the evolutionary time, have developed an impressive way to use chemical compounds to dialogue with the different protagonists of their environment (i.e., conspecifics, their hosts and the plants on which their hosts are living). Unravelling the evolutionary meaning of such chemical communication networks can give new insights into the ecology of these insects and especially on how to improve their use for the control of noxious pests in biological control programmes. Chemical Ecology of Insect Parasitoids is a timely publication, with organised chapters to present the most important knowledge and discoveries that have taken place over the last decade, and their potential use in pest control strategy. Specific relevant case studies are presented to enhance the reader's experience. Suited to graduate students and professional researchers and practitioners in pest management, entomology, evolutionary biology, behavioural ecology, and chemical ecology, this book is essential for anyone needing information on this important group of insects.

Insects have evolved very unique and interesting tactics using chemical signals to survive. Chemical ecology illustrates the working of the biological network by means of chemical analyses. Recent advances in analytical technology have opened the way to a better understanding of the more complicated and abyssal interactions of insects with other organisms including plants and microbes. This book covers recent research on insects and chemical communications and presents the current status about challenges faced by chemical ecologists for the management of pests in agriculture and human health.
