PIANO, Fiorella G. DE et al. Food supply in honeybee colonies improved kiwifruit ('Actinidia deliciosa Liang & Ferguson) (Actinidiaceae: Theales) pollination services. Rev. Soc. Entomol. Argent. [online]. 2021, vol.80, n.3, pp.31-36. ISSN 0373-5680.  http://dx.doi.org/doi.org/10.25085/rsea.800304.

The current agriculture model determines a decrease in semi-natural habitats leading to poor nutrition for honeybee colonies, which usually need to be food supplemented. Honeybees are used to transfer pollen between male and female kiwifruit (Actinidia deliciosa Liang & Ferguson) plants, increasing fruit quality and crop yield. Our main goal was to determine the effect of stimulating Apis mellifera L. colonies with standard food supplies on the collection of kiwifruit pollen. However, honey bees can also forage other flowering species in the crop site's surrounding areas. We selected kiwifruit as a model to analyze the effects of food supply on pollen collection of the target crop. The following experimental treatments (n = 5 hives each were conducted in a kiwifruit orchard in Mar del Plata, Argentina: Group J/A: supplied with sugar syrup (2:1 + liquid protein supplements ("Api-promotor®”; Group J/P: supplied with sugar syrup (2:1 + solid protein supplements ("patty”; Group J: supplied with sugar syrup (2:1; Group C: control, not supplied. Colonies supplied with J, J/P and J/A collected more kiwifruit pollen than the other two treatments, even under other flowering species in areas nearby. Although honeybees collected most pollen from other plant species of semi-natural habitats, J/P, J, and J/A treatments can significantly improve the honeybees' kiwifruit pollination service.
