Honeybees can be moved where needed and are not picky about the flower they visit to collect pollen and nectar which they feed on. Thanks to these qualities, they are the major crop pollinators relied on by humans. The honeybee equals and sometimes surpasses all other wild pollinators for this task.
In the last decade, many studies focused on honeybee health to identify the causes of unusually high colony losses. Most of this work has been performed in Europe
and North America
where bees are exploited in large scale commercial operations. Scientists observe interactions of many factors affecting honeybee health
But these results are so far not sufficiently clear to understand the causes of the declines and implement adapted mitigation measures. Scientists and beekeepers will first need to understand the reasons for deaths amongst bees before they can adjust their practices to ensure the stocks' survival.
Honeybee health status or even basic data of population sizes in the wild before the modern beekeeping area is unknown. We lack important information to evaluate the severity of the current problem. Understanding how bees deal with pests, pathogens and other environmental factors in Africa, where beekeeping has not been as intrusive, could help scientists understand more about why the bees of Europe and North America struggle.
How can African honeybees help?
The honeybee, Apis mellifera, is also present in Africa
. In contrast to the docile European honeybees, African honeybees are more aggressive
to beekeepers and are rarely confined to man-made hives. The majority of their estimated 310 million colonies strong population is wild and lives in natural cavities in trees or ground.
A lack of data on the health status of African honeybees has prompted several international teams to investigate this issue in recent years. In attempting to deal with the problem of colony losses, beekeepers and scientists throughout the world posed the following questions:
1) Is it possible that by developing beekeeping to the current industrial level, we pushed the honeybees to their biological limits? When managing these pollinators, do we place them in such unnatural situations that they are weakened?
2) Was the selective breeding used to improve desirable traits such as honey production or docility done at the expense of their defence mechanisms?
3) Does the wide scale honeybee trade result in the spread of damaging pathogens to which the honeybees are not adapted?
