Although wild pollinators are better
conserved within protected areas and natural parks, where floral diversity and
shelters are available, for agricultural production it is more convenient to
conserve pollinators within agricultural fields.
Recently, implementation of
floral margins in agricultural landscapes has been shown to increase the
abundance of pollinators in agro-ecosystems and positively affects production
of neighbouring crops. However, special attention should be focused on the selection of beneficial in sectary plants and their management in the agro-ecosystems. Therefore, this short review highlights the importance of
choosing appropriate plants to attract beneficial insects and to consider their
attractiveness to pollinators, ecology, physiology, floral phenology, and
potential weediness prior introducing them in agro-ecosystems.
