A team of researchers developed a food supplement that mimics the nutrients bees get from pollen. When tested, colonies fed this supplement produced up to 15 times more young.

Honeybees are in trouble. Their populations are declining due to poor nutrition, climate change, and other factors. A team of scientists from the University of Oxford, Royal Botanic Gardens Kew, the University of Greenwich, and the Technical University of Denmark worked together to create a food supplement that could help reverse this trend.

The researchers analyzed tissues from pupae and adult bees to figure out what they actually need. They identified six key nutrients called sterols that are crucial for bee growth and development. However, these sterols are not available naturally in quantities that could be harvested on a commercial scale, making it difficult to create a nutritionally complete feed.

To solve this problem, the team engineered yeast to produce these sterols efficiently. They added this yeast to bee diets and tested it over three months in controlled experiments. The results were dramatic - colonies receiving the enriched diet produced up to 15 times more larvae that reached the pupal stage compared with those on standard diets.

The scientists believe that this supplement could be a game-changer for honeybees. Honeybees are responsible for pollinating over 70% of major global crops, but their populations are under severe pressure. This new supplement could help strength these colonies and ensure the continued production of food.

Why It Matters

This breakthrough has significant implications for India's agricultural sector, which relies heavily on honeybees for crop pollination. By developing a nutritionally complete feed for bees, we can help ensure the continued health and productivity of these crucial pollinators.
