Question 4

A colony of honey bees Affected by CCD (note the small number of adult workers relative to a large amount of unhatched brood that forms the waxy cells in the hive frame. Frames 1 and 3 are most greatly affected.
In 2007, a significant proportion of American beekeepers complained of unusually large losses of bee populations from their overwintering levels in late 2006. Loss of some colonies (approximately 10%) in early spring is normal and occurs every year. The problem was also reported by beekeepers in Europe, and researchers do not understand the specific causes of these losses.
At present, the syndrome is mysterious given that the main symptom is simply a low number of adult bees in the hive. There are no dead bodies and despite the fact that the affected colonies do co-exist with many disease organisms, no external signs of disease, pests or parasites seem to exist.
Going forward, which of the following observations and associated questions might not reasonably lead to testable scientific investigations into CCDs root cause(s)?

A
Beekeepers in 22 states, including Hawaii, reported larger than average population declines. Were the losses in 2007 within normal range?

B
The parasitic mite, Varroa destructor, infests brood (larvae) cells and lives on and is carried by adult bees. If heavy mite infections are visible to professional beekeepers, could a link be made between CCD and Varroa parasitism?

C
A certain protozoan, Nosema apis, infests the guts of adult bees and, when present in high numbers, causes dysentery (associated with diarrhea and fluid loss). If colonies, yet to experience CCD, feature Nosema infestation and are treated to eradicate the parasite, will this prevent CCD?

D
It has been noted that a variety of viruses affect adult bees. Under conditions of stress viral populations can increase and cause CCD symptoms (e.g. paralysis, trembling and an inability to fly) in adult bees. Typically, stressful triggers include poor nutrition, bad weather or parasitism. If a virus is present with a larger number of stressors (i.e. poor nutrition and hosting two parasites), will the symptoms of CCD be greater than infection by virus alone?
