Which environmental factor is detrimental to bee health?

Pesticides are indeed a significant factor that can detrimentally affect bee health. They can disrupt the nervous system of bees, impair their foraging behavior, reduce their reproductive capabilities, and even lead to colony collapse. The use of certain pesticides, particularly neonicotinoids, has been linked to harmful effects on bee populations, including increased mortality rates and weakened immune systems. Because bees play a crucial role in pollination for many crops and wild plants, the impact of pesticides can have far-reaching consequences for both bee populations and the ecosystems they support.

While excessive moisture, high temperatures, and low humidity can pose challenges to bee survival and productivity, they typically do not have the same direct and severe impact as exposure to pesticides. Environmental stressors like moisture and temperature fluctuations can affect the bees' ability to regulate their hive environment and may lead to conditions favorable for disease, but they are often not as immediately harmful as the toxic effects of chemical pesticides.
