United States. Bureau of Entomology

The Division of Entomology was formed in 1863. Early heads of this division included Townend Glover and Charles Valentine Riley. Early research included the development of insect control and eradication practices, as well as the identification of insects and their life cycles. In 1904 the 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.
