Current thinking holds that bee health is dependent upon a complex interplay of environmental factors.
Like most living creatures bees need air, water, food and shelter for basic survival. They also need to exercise the biological imperatives and pheromone responses that enable their species to function properly and to perpetuate.
Anything which interferes with these elements will affect the bees' wellbeing and health. This might include - the weather, available forage, integrity of the nest site (or hive), genetics, pests, diseases or human interference.
Combinations of these factors are now thought to have more impact on bees' health than any single disease. Examples include - viral infections secondary to Varroa infestation, cross-infection by poor apiary management, succumbing to pathogens when stressed or immune systems weakened as a result of inadequate diet. The multiplicity of problems for bees are yet to be fully researched and understood.
The role of the beekeeper should focus on ensuring the essentials (air, water, food, shelter) are adequately provisioned and that interference is kept to a minimum. Detrimental human interference might include - overly frequent hive inspections, rough handling, taking too much honey, inappropriate treatments (eg prophylactic antibiotics), cross-infection, poor land management and inappropriate use of insecticides. Lack of intervention can be equally detrimental; for example, failure to - isolate disease adequately, feed when needed, maintain hives properly, provide protection against pests.
Careful observation can reveal much about the health of the colony. Correctly informed observation will help determine whether intervention is appropriate (or desirable). We cannot control the weather, but we can apply a programme of integrated pest management to minimise the risks of disease.
Bee health is also vital for our health. We are dependent upon their activities as pollinators of our crops. There is little dispute that our over-exploitation of the environment and the honeybee has had an adverse effect on bee populations. Much of this was done in ignorance. Now we know better, we must rise to the challenge and redouble our efforts to maintain and improve the health of bees - it is in our interest to do so. |
