Abstract: | The targeted pollination strategy has shown positive results in directing honey bees to crop flowers
offering nectar along with pollen as reward. Kiwifruit is a functionally dioecious species, which relies
on bees to transport pollen from staminate to pistillate nectarless flowers. Following the targeted
pollination procedures recently validated, we first developed a mimic odor (KM) based on kiwifruit
floral volatiles for which bees showed the highest level of generalization to the natural floral scent,
although the response towards pistillate flowers was higher than towards staminate flowers. Then,
in the field, feeding colonies KM-scented sucrose solution resulted in higher amounts of kiwifruit
pollen collected by honey bees compared to control colonies fed unscented sucrose solution. Our
results support the hypothesis that olfactory conditioning bees biases their foraging preferences in a
nectarless crop, given the higher visitation to target flowers despite having provided the mimic odor
paired with a sugar reward. |
