Abstract
Field studies conducted in cherry orchards of the Willamette Valley, Oregon, indicate that diapausing pupae of the western cherry fruit fly, Rhagoletis indifferens Curran, overwinter in the soil at a depth of 1–4 in. Relatively very small numbers of pupae were collected from surface debris and soil samples taken at a depth of 6 in. and below. The number of flies emerging from different soil depths indicated that removal of the top 6 in. of soil caused a 99% reduction in adult emergence, while the removal of the top 1 in. of soil had no effect.Keywords
