The knowlegment of repellants substances to phoride flies is an important step to the Brazilian stinglessbee beekeeping due to the serious damage to the native bee hives they can do. The copaiba and andiroba oils, found commonly in the Amazon region, are very employed by the traditional people as insects' repellants. We observed the effect of these oils over the phoride's laying in laboratory conditions. The female phoride's eggs occurred preferentially in the pollen substrate and statistically differed from those containing andiroba and copaiba oils, which was strongly reduced (until none eggs were laid), and from the substrate containing honey. These oils showed to be quite good alternative for this plague's preventive and curative control in stingless bee hives due to its repellant effect, low cost, and availability to get it in the region.
