Agricultural entomology has been a focus of the INHS since its inception over 150 years ago.  The Office of the State Entomologist was established in 1867 when Benjamin D. Walsh was appointed (1867 - 1869), followed by William LeBaron (1870 - 1875), Cyrus Thomas (1875 - 1882), and Stephen A. Forbes (1882 - 1917).  Though different titles have been used over the years (State Entomologist, Chief Entomologist, Section Head for Economic Entomology) the distinction of the entomological research has not diminished and continues to this day, with researchers studying soybean aphids, western corn rootworms, and other threats to the agricultural economy of Illinois.
