Excerpt: Fourty years ago, the amount of fruit produced by the cherry industry in Michigan exceeded that of all other states combined. State and federal regulatory agencies permitted no tolerance for maggots in cherries to be used as human food, and when such fruit was found to be infested, it was seized and ordered destroyed. Two species of fruit flies were known to infest cherries in Michigan, Rhagoletis congulata Loew (cherry fruit fly) and R. fausta Osten Sacken (black cherry fruit fly).
