Latest buzz on bee decline: Studies blame pesticides

WASHINGTON (AP) -- A common class of pesticide is causing problems for honeybees and bumblebees, important species already in trouble, two studies suggest. But the findings don't explain all the reasons behind a long-running bee decline, and other experts found one of the studies less than convincing. The new research suggests the chemicals used in the pesticide -- designed to attack the central nervous system of insects -- reduces the weight and number of
queens in bumblebee hives. These pesticides also cause honeybees to become disoriented and fail to return to their hives, the researchers concluded. The two studies were published online Thursday in the journal Science. Just last week activists filed a petition with more than a million signatures asking the government to ban the class of pesticides called neonicotinoids. The
U.S. Environmental Protection Agency said it is re-evaluating the chemicals and is seeking scientific help.
