Summary
<p>In this study, the effects of differently processed poppy (Papaver somniferum) and ladania (Cistus creticus) pollens on the midgut histology of Efe bee (Apis mellifera anatoliaca) were investigated for the first time. The worker bees kept in a total of 27 cages were fed with fresh, pre-treated, and fermented poppy, ladania, and mixed (%50 poppy+%50 ladania) pollens for 14 days, and the midgut inner and outer diameters, epithelial thickness, and digestive cell counts were evaluated. The significant increase in midgut diameter in bees fed with fermented poppy pollen compared to those fed with fresh poppy pollen suggested that fermentation supports the digestion and utilization of nutrients. In ladania pollen, the effect of fermentation was particularly evident at the cellular level, the number of digestive cells in the fermented ladania pollen decreased significantly compared to the fresh ladania pollen. This finding was associated with the disruption of the pollen wall by fermentation and the subsequent facilitation of nutrient absorption. The fact that the epithelial thickness was unaffected by the treatments in both the pollen groups, indicated that fermentation and physical pre-treatments did not cause any distinct pathological changes in the ventriculus. The effect of fermentation was demonstrated by an increase in midgut diameter in the poppy pollen and a decrease in digestive cell count in ladania pollen. Consequently, instead of feeding honeybees pollens in their fresh form, administering fermented poppy and ladania pollens is recommended, particularly to protect the digestive health of the Efe bee, accelerate colony development, and enhance bioavailability.</p>
