Resumo: Coenosia attenuata Stein (Diptera: Muscidae) is a species that belongs to the tigrina group. It is considered as a generalist predator of agricultural pests in both larval and adult stages. In this work, rearing methods developed by other authors were adapted/ changed in order to improve mass production of this predator. There were more emergences occurring in substrates with larger number of sciarid larvae and in cages with more than five parental couples. Those collected in the field showed higher emergence rates in the next generation when compared with laboratory-reared individuals. Regarding rearing substrate optimization, the highest number of emergences was observed in the substrate constituted by a mixture of soil and coconut coir. In the absence of pests as preys, C. attenuata may attack beneficial insects. An evaluation of the consumption rates over Diglyphus isaea Walker was also made. D. isaea is a common parasitoid relevant in greenhouse systems in Portugal. Mated adult females of C. attenuata showed higher predation rates over D. isaea than other female categories tested; females captured more individuals (11 per day on average) than males (7 per day on average) and were also more voracious on prey consumption.
