This program, in conjunction with USDA, evaluates and issues permits for individuals to move insects, plant pathogens, foreign plants, and soil into Iowa, often for research purposes. Injurious pests can not be moved, unless they are contained in special confinement settings. Other pests of a less serious nature are allowed entry for experimental purposes and for other purposes (e.g., for butterfly releases at weddings). Certain plants (for example roses, which might harbor rose viruses) are allowed entry into the US by USDA from foreign countries.
