Abstract
In laboratory tests, Ravinia lherminieri (Robineau-Desvoidy) larvae significantly reduced the numbers of face fly, Musca autumnalis De Geer, eggs or larvae (98% mortality), in 100 ml of bovine feces at R. lherminieri to face fly ratios down to 10:200. Face fly immature mortality due to R. lherminieri decreased from 98% to 0% as the volume of feces per larva increased from 10 ml to 80 ml. Although R. lherminieri larvae survived on feces alone, their survival increased 26% (63% vs. 89%) when face fly immatures were added to the feces.Keywords
