High population density of bee pollinators increasing Camelina sativa (L.) Crantz seed yield: Implications on the potential risk for insect-mediated gene flow

•Different densities of bee pollinators on camelina seed yield were assessed.•A higher densities of honey bee population increased camelina seed yield.•Principle coordinate analysis was used to identify camelina pollen origin.•Bees carrying camelina pollen raised ecological concern on insect-mediated gene flow.
