Handbook of Medical Entomology

"Handbook of Medical Entomology" by William A. Riley and O. A. Johannsen is a scientific publication written in the early 20th century. The book serves as an extensive reference guide that integrates lectures from the authors' courses on the relationship between insects and the transmission of diseases. It aims to provide a comprehensive overview of how various arthropods affect human health through poison, parasitism, and disease transmission, making it valuable for medical and entomological studies. The opening of the handbook sets the stage by emphasizing an evolving understanding of insects as vectors of disease, rather than merely nuisances to humans. It highlights historical perspectives on insect-borne diseases, referencing early theories and the contributions of significant figures like Mercurialis and Beauperthuy. The authors outline the various roles arthropods can play in human health, categorizing their interactions into three main groups: direct poisoning through bites or stings, parasitism, and the ability to transmit diseases either as carriers or essential hosts for pathogens. This foundational discussion serves to prepare readers for the detailed exploration of specific insects and their impacts in the subsequent chapters. (This is an automatically generated summary.)
