Insect Sex Pheromones is a revised and expanded edition of the book "Insect Sex Attractants" and covers greater discoveries in the field of sex pheromones. It is discovered that many sex pheromones are sexually excitatory rather than attractive. This discovery prompted the substitution of the more accurate and encompassing term "pheromones" for the term "attractants" in the title of this edition. Composed of 13 chapters, this book has chapters that cover the occurrence in female and production in male of sex pheromones in various insect species. The insect orders considered include Acarina, Orthoptera, Hemiptera, Homoptera, Diptera, Isoptera, Neuroptera, Siphonaptera, Coleoptera, Hymenoptera, Lepidoptera, Trichoptera, and Mecoptera. The following chapter discusses pheromones produced by one sex that lure to assemble for mating. This book goes on discussing the anatomy and physiology of scent glands of male and female insects; the attractant perception mechanism; and the behavioral and electrophysiological responses of insects to sex pheromones. Other chapters are devoted to the influence of several factors on the presence of chemical sex attraction or excitation in any insect. The concluding chapters deal with the collection, isolation, identification, synthesis, and analysis of sex pheromones. This book will greatly appeal to research and economic entomologists, insect physiologists, chemists, and ecologists.
