Do we know what has caused the colony collapse disorder?

    No one theory has been confirmed, but some common ones are pests, pesticide-carrying plants, and even cell phone radiation.

    The short answer is no, we do not yet fully understand the cause–or causes–of CCD. However, research over the past few years has found a number of plausible causes that fit the data:

    -Biotic factors, such as the Israeli Acute Paralysis Virus (this virus was found in 25 of 30 studied colonies that had experienced CCD and only 1 of 21 studied non-CCD colonies)

    -Malnutrition (one study argues that all reported cases of CCD have been preceded by periods of drought and nutritional stress)

    -Pesticides, particularly nicotine-based pesticides (scientists found that these pesticides–toxic to bees–tended to adhere to pollen; as such, one bee could collect toxic pollen, bring it back to the colony, and thus poison a great deal of the colony)
