Un estudio dirigido por la Universidad de Oxford ha desarrollado un complemento alimenticio manipulado que podría ayudar a invertir el alarmante declive de las poblaciones de abejas melíferas.

London

Scientists at Oxford University have developed a new superfood supplement for honeybees using the yeast Yarrowia lipolytica. This supplement is designed to mimic the nutritional profile of pollen, providing essential sterols and other nutrients that are often missing from commercial pollen substitutes. 

Initial three-month trials showed that bee colonies fed with the new supplement reared up to 15 times more larvae to the pupal stage and sustained brood production longer than those on standard diets. Large-scale field trials are planned, with commercial production targeted for 2026 in partnership with Belgian company Apex Biosciences. The supplement is expected to be more expensive than current alternatives but aims to offer complete nutrition for bees.

Un nuevo "superalimento" podría ayudar a las abejas melíferas

Los científicos afirman haber desarrollado un nuevo superalimento que podría ayudar a las abejas melíferas. El suplemento está diseñado para imitar el polen y puede mejorar significativamente la reproducción de las colonias. Cuando las abejas tienen una buena nutrición, deberían ser capaces al menos de dar lo mejor de sí mismas. contra estas enfermedades y patógenos y plagas que actualmente no tenemos herramientas para combatir. Así que realmente creemos que esta es una piedra angular en el problema de la disminución de las abejas que afortunadamente hemos sido capaces de resolver. Las abejas melíferas son polinizadoras fundamentales para más del 70% de los cultivos mundiales, pero se enfrentan a las crecientes amenazas del cambio climático, la agricultura intensiva, las plagas y los patógenos. Empezamos a comprender que había lagunas en el año en las que las abejas simplemente no disponían de suficiente alimento y esto era cada vez más importante ya que la polinización de los cultivos dependía de las abejas domesticadas. Geraldine Wright forma parte del equipo dirigido por Oxford que diseñó la levadura Yarrowia lipolytica. La tecnología que se ha desarrollado en mi laboratorio nos permite crear un alimento... que no depende del polen floral. Podemos fabricar un sustituto del polen para alimentar a las colonias de abejas... que representa su nutrición completa. El polen es un componente dietético clave para las abejas y proporciona lípidos específicos llamados esteroles que son vitales para el desarrollo de las abejas. Pero los sustitutos comerciales del polen suelen carecer de esos nutrientes, a diferencia del nuevo superalimento. El uso de esta levadura para producir estos esteroles significa que podemos hacer un sustituto del polen que puede mantener las colonias de abejas indefinidamente. Y esto es realmente un gran avance para los apicultores. En ensayos de tres meses, las colonias alimentadas con el suplemento criaron hasta 15 veces más larvas hasta la fase de pupa. en comparación con las alimentadas con dietas estándar. También mantuvieron la producción de cría durante más tiempo. Ahora se planean ensayos de campo a gran escala para confirmar los beneficios a largo plazo de este superalimento. la empresa belga Apex Biosciences se asociará con el equipo de Oxford para iniciar la producción comercial en 2026. Uno de los aspectos importantes a la hora de diseñar el sustituto del polen era que fuera asequible para los apicultores. Nuestro sustituto del polen va a ser más caro que los que hay actualmente en el mercado, pero es el alimento perfecto.
