Climate change


Due to the acceleration of climate change, an increasing amount of plants come into bloom in the same period. This causes a huge problem.

Bees have a preference for gathering nectar; the concentration of blooming plants can therefore result in insufficient pollen storage. Pollen requires at least 14 days for fermentation through enzymes added to it by the bees. 

Adult bees can digest fresh pollen, but the brood cannot! Because their digestive system does not yet contain enzymes, they require pre-digested or fermented pollen. 

Climate change disrupts the two-week storage system normally observed by bees. Because supply sometimes stops completely due to bad weather, not all pollen gets a chance to ferment completely.  

Insufficiently digested pollen causes fat deficiency in the brood; this cannot be corrected after birth. The larval stage of the brood is of crucial importance and under normal circumstances it should grow up in an abundance of nectar and pollen. The reduced period of bloom, however, causes shortage of fermented pollen in the hives. The bees’ solution to feed the brood fresh pollen results in higher amounts of waste in the larvae’s digestive system and makes them more susceptible to various diseases.
