XXIIIrd International Congress of Pure and Applied Chemistry, Volume 3 documents the proceedings of the XXIIIrd International Congress of Pure and Applied Chemistry held in Boston, USA on July 26-30, 1971. This book discusses the aspects of growth and reproduction by hormones of insects, focusing on ecdysone and juvenile hormone. Ecdysone is closely related to the plant and animal sterols, while juvenile hormone to simple plant terpenes. The social behavior of insects that is controlled to a considerable degree by chemistry is also discussed. The effects range from long-term hormonal aspects, such as the production of queen bees by appropriate feeding, or the maintenance of sterile workers, to the more evanescent effects of pheromones. This compilation is valuable to chemists, entomologists, and biologists interested in insect chemistry.
