Eight chapters consider the latest research and thought in the study of how insects use chemical signals to communicate with each other or to interact with other species. Written by internationally recognized experts, they focus on topics such as plant defenses against insects, floral odors that attract pollinators, host finding by parasitic insects, and pheromone-mediated interactions in cockroaches, moths, spiders, and mites. The book is essential reading for researchers and graduate students of chemically mediated communication in insects.
