Resumen:
Honeybees play a key role in the environment, conserving biodiversity through pollination. However, in temperate climate colonies are exposed to different stressors that affect Apis mellifera? health, leading to colony losses and depopulation of bees. Honeybee-bacteria symbiosis has been claimed as an alternative to enhance bee-health. In this study, we evaluate the effect on development, pathologies and nutritional aspects of colonies fed with a free supernatant of Lactobacillus johnsonii AJ5 cells (CFS). Particularly, we evaluate population parameters (adult bee, open and sealed brood), fat bodies and soluble proteins present in abdomens, honey reserves, Nosema ceranae load, and Varroa destructor infestation. The results showed an increase of adult bees and sealed brood, but without differences in the amount of open brood. Also, CFS supplementation did not change the fat bodies and soluble proteins levels in the abdomen. N. ceranae prevalence and intensity did not suffer changes related to the CFS treatment, however it showed a tendency to a reduction of the V. destructor infestation. Lastly, CFS produced an increase in the storage of honey. This study provides information about a product based on bacterial metabolites synthesized by L. johnsonii AJ5, which has shown to intensify the production of honey, also favoring a tendency against V. destructor proliferation.
