Most poultry production issues are linked to a combination of factors related to management, stress, nutrition and exposition to pathogens. Diet supplementation with functional feed, products that provide a health benefit beyond basic nutrition, may contribute to reducing some negative effects of captive breeding. Several essential oils (EO) and their components have bioactivities on animal physiology and metabolism including antioxidants, anticholesterolemics, antimicrobials, andinsecticidal, among other. The aim of this research was to evaluate if the modification of quail diet,supplementing it with the EO components thymol or isoeugenol, could have an effect on theproduction of flies in poultry litter, a sanitary and economic poultry related issue. Manure samplesdeposited in the previous 0 to 48 hs by quail that were fed with a supplementation of 2000 mgthymol, isoeugenol per kg of feed or no supplement (control) were collected. Each 200g sample (6replicates per treatment) was incubated in a container inside an emergence cage. Cages wereinspected daily and adult flies that emerged were collected for 40 days. The effect of quail feedsupplementation on the number of emerging flies, species composition and emergence times wereassessed. Significantly less fly emerged from manure from the thymol treatment (P < 0.05) and atendency to lower emergence was observed from isoeugenol (P = 0.09). Significantly fewer Musca domestica emerged from thymol (P
