Ann. appt. Biol. (1964). S3. 175-228 Printed in Great Britain*75APPLIED ENTOMOLOGY IN BRITAINThe following six papers describe various aspects of applied entomology in the United Kingdom and are published in the Annals of Applied Biology as part of the arrangements being made for the Xllth International Congress of Entomology to be held in London on 8-16 July 1964.Veterinary entomologyBY W. N. BEESLEY Ministry of Agriculture, Fisheries and Food, Central Veterinary Laboratory,Weybridge, SurreyThere are in the United Kingdom (England, Scotland, Wales and Northern Ireland) some 29-5 million sheep, 11-9 million cattle, 6-8 million pigs and 109 million poultry. By contrast there are only about 200,000 horses, and only one-quarter of these are employed in farm work. About seventy species of arthropods may infest our farm livestock and pet animals, and representative pests are listed in Table 1. Various species of mites and lice are the most common parasites, some being highly specific and restricted to one host.Table 1.

Some research on veterinary entomology is done at these institutions, and in the various zoology and agricultural departments
