Which of the following is NOT a trait of a healthy bee colony?

A healthy bee colony exhibits several key characteristics that indicate its vitality and productivity. Active foraging is essential as it shows that the bees are actively gathering nectar and pollen, which is vital for their survival and the production of honey. Uniform brood patterns reflect the colony's reproductive health, suggesting that the queen is laying eggs effectively, and the workers are maintaining optimal conditions for brood development. A strong population of foragers indicates that the colony is robust and capable of meeting its nutritional needs while also supporting hive growth.

The presence of large numbers of disease symptoms contradicts these traits of health and productivity. When disease symptoms are prevalent, it typically indicates underlying issues such as poor colony management, pests, or inadequate living conditions. This might lead to decreased foraging activity, irregular brood patterns, and ultimately a weakening colony. Thus, the presence of disease symptoms is not consistent with a healthy bee colony, making it the correct choice in identifying what is NOT a trait of a healthy colony.
