The object of this study was to provide an estimate of the financial losses caused in Michigan's apple orchards by members of the genus Miarotus, and, if possible, to discover some of the factors affecting the amount of damage. Information was collected from apple growers and from direct observation of 1,520 Michigan apple trees. Data was collected concerning the winters of 1972-73 and 1973-74. Both of these years were characterized hy relatively low populations of microtine rodents in Michigan.
