Spice of life for bumble bees– ScienceDaily

The yield and quality of lots of crops gain from pollination, however it isn’t simply honey bees that do this work: bumble bees likewise have a function. Nevertheless, positioning honey bee or bumble bee nests beside the field does not ensure that they will check out the preferred plants because there might be other plant types blooming at the exact same time that show more appealing. A group from the University of Göttingen, together with scientists from the University of Applied Sciences Mittweida and the Julius Kühn Institute, utilized ingenious molecular biological techniques and standard microscopy to examine the pollen gathering behaviour of honey bees and bumble bees in farming landscapes. They reveal that bumble bees take a lot more pollen from dif-ferent plant types than honey bees to please their requirement for protein. Additionally, less pollen from the target– in this case strawberry plants– is gathered when there are fields of blooming oilseed rape in the surrounding landscape. The outcomes have actually been released in the journal Molecular Ecology

The scientists put honey bee and bumble bee nests beside strawberry fields in the Göttingen and Kassel area and gathered pollen from returning honey bees and bumble bees. The bees gather the pro-tein-rich pollen generally for feeding their offspring. The pollen DNA was examined working carefully with the Department of Molecular Biology of Animals and molecular Diagnostics at the University of Göttingen, and the Department of Biochemistry/Molecular Biology of the Mittweida University of Applied Sciences. “DNA analysis informs us which plant types the bees have actually gone to and how varied their foraging behaviour is. To do this, we sequenced the DNA of the pollen and compared the series utilizing a database of local plant types,” states Dr Svenja Bänsch, post-doctoral scientist in Practical Agrobiodiversity at the Uni-versity of Göttingen.

” Our research study reveals that honey bees and bumble bees utilize really various plants to source their pollen in the landscape. In specific, the vast array of bumble bee nutrition, which they discover generally in flower-rich habi-tats, must be considered when taking actions to enhance nature preservation. Both honey bees and bumble bees, whose nests can be bought or leased, appropriate pollinators in strawberry growing. Nevertheless, naturally happening wild bees must be motivated as a top priority,” concludes Teacher Catrin Westphal, Head of Practical Agrobiodiversity at the University of Göttingen.
