Intraspecific communication involves the activation of chemoreceptors and subsequent activation of different central areas that coordinate the responses of the entire organism—ranging from behavioral modification to modulation of hormones release. Animals emit intraspecific chemical signals, often referred to as pheromones, to advertise their presence to members of the same species and to regulate interactions aimed at establishing and regulating social and reproductive bonds. In the last two decades, scientists have developed a greater understanding of the neural processing of these chemical signals. Neurobiology of Chemical Communication explores the role of the chemical senses in mediating intraspecific communication. Providing an up-to-date outline of the most recent advances in the field, it presents data from laboratory and wild species, ranging from invertebrates to vertebrates, from insects to humans. The book examines the structure, anatomy, electrophysiology, and molecular biology of pheromones. It discusses how chemical signals work on different mammalian and non-mammalian species and includes chapters on insects, Drosophila, honey bees, amphibians, mice, tigers, and cattle. It also explores the controversial topic of human pheromones. An essential reference for students and researchers in the field of pheromones, this is also an ideal resource for those working on behavioral phenotyping of animal models and persons interested in the biology/ecology of wild and domestic species.

Phase and Caste Determination in Insects: Endocrine Aspects is a collection of papers presented at a Symposium of the Section Physiology and Biochemistry of the XV International Congress of Entomology, held in Washington, D.C. in 1976. Contributors explore the endocrine aspects of phase and caste differentiation in insects, with emphasis on the crucial roles of juvenile hormone (JH) and queen bee determinator. This book is comprised of 11 chapters and begins with a discussion on the role of JH in caste formation in honey bees, bumblebees, and termites. Subsequent chapters explore environmental, genetic, and endocrine influences in caste determination in the stingless bee; endocrine control over caste differentiation in higher termites and Myrmicine ants; the influence of external factors on hormone effects in termite caste determination; and the role of JH in the polymorphism of aphids. The final chapter deals with the regulation of aphid polymorphism by neurosecretory cells. This monograph will be a valuable resource for entomologists, endocrinologists, physiologists, and biochemists as well as insect enthusiasts.
