Bees have a greater impact on the planet than meets the eye. From pollinating flowers to helping produce the fruits and vegetables we love, bees are the unsung heroes of the ecosystem. But did you know that a bee’s diet plays a vital role in their daily work and survival?
When it comes to their diet, it’s not just sugars and starches that matter: We’ve got news straight from the hive that might help them do their job better.
A new study reveals that a balanced honeybee’s diet directly impacts their health and work performance.
A balanced bee diet, a balanced hive
The man behind this fascinating research is Professor Shaloni Shafir of the Hebrew University of Jerusalem.
Professor Shafir’s research in the Robert H. Smith School of Agriculture, Food and the Environment delves deep into the nutritional balance of honeybees and its impact on the bees’ overall health and homeostasis.
This study paints a clear picture that a balanced diet is not just a nice-to-have for honeybees, it is a necessity for optimal bee health.
The overall work success of these hardworking creatures, especially raising the larvae, depends on nutrition. Without a balanced diet, a bee’s ability to raise their young can be hindered.
Nutrition from the honeybee diet
What does a balanced diet mean for our active friends? One important aspect is the Omega 6:3 ratio.
Professor Shafir’s research found that a 5:1 ratio of omega-6 to omega-3 was harmful to honeybees. With this unbalanced diet, it took the bees longer to start lactating, they lactated less frequently, and the needs of the larvae on their third and fourth days of life were not adequately met.
Bees don’t have access to nutritional labels like humans do, nor can they check the ratio of omega-6 to omega-3 before deciding on their diet, so who makes sure the bees’ diet is balanced?
Balanced and unbalanced diets
The researchers split day-old worker bees into two groups, one of which was fed a balanced diet and the other an unbalanced diet for seven days.
All bees were then sent to hives in a communal garden, barcode tagged, and photographed continuously over a period of six days.
The protagonists of this intriguing discovery were the bees from the group that had an unbalanced diet: they showed delayed parenting behaviour and a reduced efficiency in caring for their larvae, which was exactly what Professor Shafir had predicted.
A big step for bees
The results of this study have significant implications, especially in cultivated lands where balanced pollen sources are scarce.
“Balanced nutrition is fundamental for honeybee colonies, affecting not only the health of each individual, but also the efficiency and survival of the hive as a whole,” Professor Shafir said.
“Our study highlights the importance of maintaining a balanced ratio of omega-6 to omega-3 in honeybees’ diets to enable them to effectively fulfil their vital role within the colony.”
An elevated omega 6:3 ratio could pose serious risks to these magnificent creatures. It could affect their health, cognitive abilities and ability to maintain a colony.
But it’s not all doom and gloom: this study paves the way for a better understanding of honeybees’ nutritional needs. It calls on us to step up our efforts to conserve diverse and nutritious pollen sources for these important pollinators.
So what can we do for our bustling companions?
The role we play
Professor Shafir’s research is consistent with a broader body of research on how nutritional imbalances affect not just honeybees but a range of other species, affecting their survival, reproductive success and even the health of their offspring.
This study is more than just a footnote in the scientific literature; it is a call to action for humanity to raise awareness and support the nutritional needs of honeybees, which, after all, play a vital role in maintaining honeybee populations and providing vital pollination services.
So the next time you see bees buzzing around the flowers in your garden, remember that feeding them a balanced diet could make all the difference – and in doing so, you’ll not only be helping bees, but the planet too.
The study has been published in the journal Animal behavior.
