United States. Entomology Research Division

The Entomology Research Division (ERD) existed under the Agricultural Research Service (ARS) from 1953-1971. In its entire existence, the only person to serve as director of the ERD was Edward F. Knipling, a pioneer of insect eradication techniques and principles. One of the major areas of research during the ERD years was screwworm eradication. This division was originally named the Division of Entomology when it was formed in 1863. Early heads of this division included Townend Glover and Charles Valentine Rilley. Early research included the development of insect control and eradication practices, as well as the identification of insects and their life cycles. In 1904 Division of Entomology reached bureau status, and research greatly expanded to include many more laboratories around the country and the creation of new inspection procedures to prevent insect pest infestation. In 1934 the Bureau of Entomology merged with the Bureau of Plant Quarantine to form the Bureau of Entomology and plant Quarantine. This new bureau was able to more efficiently cover more research topics. After the USDA reorganization of 1953, entomology research was placed under its own division of the ARS. This division was abolished in 1971, and its research functions were assigned to the Animal and Plant Health Inspection Service.
