Within the chilly climate of 2023–2024, 21.2% of the Dutch population of honeybee colonies died. While this mortality charge is lower than that of the previous chilly climate, it aloof represents a worryingly excessive quantity of bee colonies that did no longer continue to exist this chilly climate period.

The annual chilly climate mortality charge is definite thru a perceive conducted yearly by researchers from Wageningen College & Evaluate, in collaboration with de Nederlandse Bijenhoudersvereniging (NBV), Imkers Nederland (IN), the biodynamic beekeepers (BD-imkers) and educated beekeepers (BVNI), commissioned by the Ministry of LNV.

This year, it’s terribly the south and north of the Netherlands that skilled rather excessive chilly climate mortality amongst honeybee colonies. Notably, within the previous year, the highest chilly climate mortality was essentially seen within the east, center and western regions. Nonetheless, such regional adaptations are current as appropriate and flawed years alternate in beekeeping apply.

A total of 2,640 Dutch beekeepers participated this year within the annual COLOSS perceive (COLony LOSSes, www.COLOSS.org), which is conducted in bigger than 40 countries; 25% of Dutch beekeepers participated. The Netherlands has about 11,000 active beekeepers; bigger than 95% are hobbyists. Nearly half of the beekeepers (Forty eight.3%) reported that every person their hives survived the chilly climate, which is an boost from final year (38.7%). Nonetheless, 6.7% of beekeepers faced an fully extinct bee population.

Explanations for chilly climate mortality amongst bee colonies are diverse. For example, the loss of life of the queen for the length of chilly climate is lethal to the hive. Additionally, combinations of factors can endanger the health of bee colonies. If bees enter chilly climate already weakened, as an instance, ensuing from a combination of reduced and disease, the likelihood of hive mortality will improve. Two diversified predominant causes of unfortunate bee health are bee viruses and the parasitic mite Varroa destructor.

The extent to which the invasion of the Asian hornet within the Netherlands impacts chilly climate mortality is unknown. These hornets prey on insects to feed their very have larvae. Two hundred and twenty-eight beekeepers seen Asian hornets at their apiaries. The blueprint of this invasive species on the mortality of entire bee colonies within the Netherlands is advanced to estimate. Nonetheless, we suspect that the Asian hornet will play an increasing role within the of Dutch bee colonies.
