Norman Criddle, born in 1875 in Addlestone, Surrey, England, died in 1933 in Winnipeg, Manitoba, Canada, was an entomologist active in the early development of control strategies for agriculturally important grasshoppers (Insecta: Orthoptera) in the prairie croplands of western North America, as well as a naturalist-artist.Bumsted, J.

Career In 1902, faced with food crop devastation from a peak in the population of grasshoppers, Criddle developed a mixture of pesticidal toxins called the "Criddle Mixture" to combat them, and was hired by the provincial government to demonstrate its use to farmers.Gibson, A., and H. G. Crawford. 1933. Norman Criddle. The Canadian Entomologist 65:193–200. In 1913 the Manitoba government hired him as an entomological field officer, and in 1919 he was appointed the provincial entomologist.Holliday, N. J. 2006.
