The Influence of Climate Change on Behavior of Bee Colonies During Collection in Sunflower
Keywords:
climate change, sunflower, bee coloniesAbstract
Climate change can have a strong impact on plant development with negative effects on the quantity and quality of secreted nectar and changes in the entire ecosystem. The paper analyzes the implications of the evolution of meteorological factors on the behavior of bee colonies during the collection of nectar and pollen in sunflower. During June and July of the analyzed period 2018-2020, a reduction of the minimum temperature was found, with some nights that registered temperatures unsuitable for nectar secretion (7.6-9.4˚C in July 2018; 8.7-9. 5˚C in July 2019; 10.3-10.4˚C in July 2020) and periods characterized by heavy rains and storms, in a period when, normally, the maximum temperatures negatively influenced the nectar secretion in this plant. The amount of honey made by bee colonies was affected, being necessary to apply supplementary feeds to ensure the reserves for wintering.
