Publishing their findings in the journalScientific Reports纽卡斯尔大学领导的研究小组发现,the most severe disease of honey bees, caused by theVarroamite, increased as climate temperatures increased but were reduced during heavy rainfall and wind.

Data collected from visits to over 300,000 honey bee colonies highlighted how the prevalence of six important honey bee diseases interacted in different ways with rainfall, temperature and wind.

Study lead, PhD student Ben Rowland, from Newcastle University's School of Natural and Environmental Sciences, said: "Our analysis clearly shows that the risk of a colony contracting one of the diseases we examined is influenced by the weather conditions experienced by that colony. Our work highlights some interesting contrasts; for example, rainfall can drive one disease to become more common whilst another will become rarer."

Professor Giles Budge, who leads the Modelling Evidence and Policy Group at Newcastle University and was a senior author on the paper, said: "We have long known that weather can influence the ability of honey bees to leave the hive and forage for food, but to better understand how our climate can influence honey bee disease is fascinating! This new knowledge will help us predict how honey bee disease might be influenced by future climate change."

The study also investigated the effect of weather on disease hotspots. The South West of England was at increased risk of disease caused byVarroamites. In addition, the team highlighted a hot spot for risk for the notifiable and damaging disease European foulbrood in an area comprising Powys, Shropshire, Herefordshire and Worcestershire.
