Austria: Will bees with bumblebees be able to find buckwheat and rapeseed for pollination in the face of global warming

Tridge summary

A study by the University of Salzburg in Austria has explored the impact of global warming on the fragrance production in strawberries and two key crops, buckwheat and rapeseed. Conducted at different optimum temperatures, the research aimed to understand how climate change affects the volatile organic compounds (VOCs) that play a crucial role in flower communication and pollination. The study identified various VOCs in buckwheat and found that 11 out of 12 compounds tested elicited a response in bees and bumblebees, with some compounds also showing electrophysiological activity. This research highlights the need to understand how climate change affects floral aromas and the communication between crops and pollinators.

A recent study of strawberries showed that flowers cease to produce a noticeable amount of fragrance at temperatures five degrees Celsius above the optimum, so scientists decided to test the potential effect of global warming on the smells of two marginal crops with which they attract insect pollinators Scientists from the University of Salzburg, Austria, Stefan Dötterl and The Guaraches Duran Cordeiro, published the results of a floral dialogue between pollinating insects, rapeseed and buckwheat in an article published in the journal Insects 2023 on the MDPI portal. “Population growth will require food production to increase by up to 70 percent this century. And pollinating insects, especially bees and bumblebees, can help us achieve this goal, the authors write. -Communication between flowers and bees precedes pollination, making flower signaling an important step in food production. Among the floral characters involved in this dialogue, scents play a key role, providing ...
