Citrus trees are entomophilous: the formation of their fruits is linked to fertilization by insects. Bees have a special place among the pollinating insects. They carry the pollen from the stamens to the pistil of the flowers that will turn into fruit. The importance of the surfaces cultivated in orchards requires a reinforcement of this natural work of pollination by the contribution of hives at the time of the bloom of the orchards. The orchards of certain varieties of citrus require permanent protection of their pollinating bees. Groupe SMIDCOM has created a generation of closed netting structures adapted to the specifications of the orchards as well as the requirements of the citrus growers. These protective net structures play an important role to not only protect a healthy pollination system but also against bad weather and global warming, also ensure a good productivity.
