Key Features

• Timely revision of a key reference on insect ecology

• Full coverage of ecosystem structure and function balanced with essential background on evolutionary aspects

• New chapter on applications to issues such as pest management, ecosystem restoration, invasive species and environmental changes

• Case studies highlight practical and theoretical applications for topics covered in each chapter


The third edition of Insect Ecology: An Ecosystem Approach provides a modern perspective of insect ecology that integrates two approaches traditionally used to study insect ecology: evolutionary and ecosystem. This integration substantially broadens the scope of insect ecology and contributes to prediction and resolution of the effects of current environmental changes, as these affect and are affected by insects. The third edition includes an updated and expanded synthesis of feedback and interactions between insects and their environment. This updated material and a new chapter on applications of insect ecology to social and environmental issues effectively demonstrates how evolutionary and ecosystem approaches complement each other, with the intent of stimulating further integration of these approaches in experiments that address insect roles in ecosystems. Effective management of ecosystem resources depends on evaluation of the complex, often complementary, effects of insects on ecosystem conditions, as well as insect responses to changing conditions.


Researchers and professionals working in the fields of insect ecology, plant and animal ecology, aquatic ecology, forest ecology, crop management and related disciplines; natural resource managers and environmental policy-makers; upper undergraduate /graduate students studying insect ecology.

Timothy Schowalter

Timothy D. Schowalter received his Ph.D. degree in Entomology from the University of Georgia in 1979. Since 1981, he has been a professor of entomology at Oregon State University, Corvallis, studying the effects of environmental changes, including natural and anthropogenic disturbances, on arthropod communities in temperate and tropical ecosystems, and effects of herbivores and detritivores on primary production, carbon flux, biogeochemical cycling. From 1992-93, he served as Program Director for Integrative and Theoretical Ecology at the National Science Foundation, where he was involved in developing global change and terrestrial ecosystem research initiatives at the federal level. He served as a U.S. delegate to international conventions to develop collaboration between U.S. Long Term Ecological Research (LTER) sites and long term sites in Hungary and East Asia and the Pacific.

Quotes and reviews

"…this edition of Insect Ecology, An Ecosystem Approach provides a thorough, up-to-date, and well-conceived treatment of the major topics in insect ecology, and is a useful resource for courses in this subject area."--American Entomologist, Spring 2013

Praise for the first edition:
"Insect Ecology is remarkable for its scope, breadth, and comprehensiveness...Absolutely indispensable for graduate students, faculty, and professionals in entomology and ecology" -CHOICE

"The book is well written and designed. It includes excellent overview and synthesis chapters, and each individual chapter ends with a concise summary. ...I recommend that students, professionals, and amateur entomologists read this excellent volume." -ECOLOGY

"Schowalter's 2nd edition of Insect Ecology: An Ecosystem Approach is a gem - a complete course in modern ecology from the vantage point of insects in ecological systems. Accessible and engaging, yet it treats the most complex ecological phenomena from individual behavior and population processes through landscape and regional-scale issues." - Dan Simberloff, University of Tennessee

"Schowalter provides a well-illustrated, comprehensive integration of population, community, and ecosystem ecology that demonstrates the global importance of insects in terrestrial and aquatic domains. Examples from temperate and tropical studies are related to a wide range of fundamental ecological concepts. The synthesis of current literature is thoroughly developed and will be widely appreciated by beginning students and established professionals." - Alan Covich, Institute of Ecology, University of Georgia

"This very stimulating book will interest entomologists and ecologists alike. Schowalter broadens the traditional scope of insect ecology to communities and ecosystems. He gives an excellent overview how insects shape ecosystem functioning, including their critical role in major trophic interactions such as decomposition, pollination, herbivory and biological control." - Teja Tscharntke, University of Göttingen, Germany

"Insect Ecology is notable for its broad scope and clear synthesis of the diverse and major roles insects play in ecosystems. Although this well-written, excellent book will be especially appealing to undergraduate and graduate students, professionals and anyone with a serious interest in insects and their critical role in ecosystems will also benefit from it. Summing Up: Highly recommended. Upper-division undergraduates and above."--CHOICE
