Abstract: The pupal parasite Nasonia vitripennis (Walker) was released for 14 weeks on field stack of soy diatillers: grains in Shanxi province for control of house fly and other filth flies. The decrease of the field: densities on the release site of house fly, stable fly, Calliphoridae species and Sarcophagidae apecies averaged 59.9%, 32.2%, 24.5% and 14.5%, respectively. Parasitism of house fly pupae averaged 41.6% on the release site and 14.2% on the check site. The strains of N. vitripennis used in this study were effective in controlling house fly populations under the conditions imposed and at the numbers released.
