After slowly learning about writing, and numerous people have helped with that. book writing and making some mistakes, we did write But we specifically mention Sam Wen Wang and Jan the book. But we were never able to complete all the Read at College Station, TX, and Rene Davis of ARS at chapters in a particular year. Manning, with little or no Weslaco, TX. help from me, wrote the chapter on livestock lice, and that chapter was in the hands of an ARS editor at the As for secretarial help, we were assisted by several time of his death. excellent and dedicated workers. Elizabeth Ann Andrus of Texas A&M University and Suzanne Thomas, Doris Although I had only the fuzziest acquaintance with lice, Ernst, and Virginia Moffitt of ARS were outstanding I undertook the task of putting that chapter into final assistants who must have privately grieved about our form—gathering up his collection of books, bulletins, bookwriting skills and deplored the slow pace at which reprints, etc., and then indexing and filing them in we worked. alphabetical order. (Manning didn't use index cards. He had an intimate acquaintance with his collection of publications and could pull any particular one out of the stack on his desk at any time.) My tasks of learning something about lice and organizing the literature certainly delayed the issuance of this book. At about the same time, it was decided that the original plan to publish a single book at this level of detail—and keep it up to date—was impractical. So we are publish- ing one group of insects at a time. This publication is the first. So now you know how I came to write with all the authority I could muster about all the crawly little critters that I had never really wanted to learn about. Inevitably, I did become interested in them, but if you find mistakes—and Tm sure that any very discerning reader will—they are my mistakes, not Manning's. All I could do was try to remain faithful to his concept of what people might want to know about lice—or per- haps it was his concept of what people ought io know about lice. This project of writing a book about livestock insects faltered and would certainly have failed except for the guidance and support of many ARS and Texas A&M University management-type people. To name only a few, there was T.W. Edminster, who first approved "Livestock Insects'' for publication by ARS. And Rex Johnston, Claude Schmidt, Bob Hoffman, and Roger Drummond provided ample support through the years. The people from ARS Information Staff labored with us from that beginning long ago. Junith Van Deusen in particular has been the patient and persevering editor on this project. I nsect taxonomists are not in complete agreement on mouthparts, Königsmann (1960) and Clay (1970) added the scientific classification of the small, wingless, their support to hlopkins' placement of all parasitic lice parasitic insects that are commonly known by the Old in a single order. However, they believed that Hopkins' English word "lice/' Apparently Packard (1887) was the suborder Mallophaga combined groups that are not first to suggest that parasitic lice are related to the free- close kin and that use of the name Mallophaga should living booklice or barklice (= psocids) (order be discontinued.

The development of the parasitic habit by Superfamily Amblycera Suborder Amblycera Mallophaga and Anoplura was explained by Osborn Superfamily Ischnocera Suborder Ischnocera (1891 ) as having been a progression from the free-living Superfamily Rhynchophthirina Suborder Rhynchophthirina state to a semiparasitic form that sometimes fed on both Suborder Anoplura Suborder Anoplura plants and vertebrate hosts to the modern parasite.
