Functional foods are products that provide a health benefit beyondbasic nutrition. Several essential oils (EO) have bioactivities onanimal physiology and metabolism (antioxidants, anticholes-terolemics), are antimicrobials, insecticides, among other. The aimof this research was to evaluate if the modification of quail diet(supplementing it with EO thymol and isoeugenol) could have aneffect on another sanitary and economic poultry related problem:the production of flies in poultry litter. Samples of manure depos-ited in the previous 0 to 48 hs by quail that were fed with a supple-mentation of 400 mg thymol, isoeugenol or butylated hydroxytolu-ene (control) per kg of feed were collected. Each 200g sample (6replicates per treatment) was incubated in a glass container insidean emergence cage. Cages were inspected daily and adult flies thatemerged were collected for 40 days. The effect of quail feed supple-mentation on the total number of emerging flies and on the numberof specimens from the 3 most frequent species (Ophyra aenescens,Muscina stabulans and Musca domestica) were assessed. Signifi-cantly less fly emerged from manure from the isoeugenol tre atment,suggesting that the modification of the quail diet with this compo-nent may have a moderate insecticidal effect against these insects.
