After doing more research on the Pioneer Databases, I found an article that explains more about the disappearance of the bees. An article on EBSCO said that many hives around the country are experiencing colony collapse disorder (CCD). Hackenberg, a Pennsylvanian bee keeper, had 400 gives on his site and all but 32 hives had collapsed. What was strange about this is that there were no dead bees in sight. Even the moths and beetles that usually raid the hives would not go near the dead bees old homes. They found that high levels of neonics, which are known to disrupt the nervous systems of the bees, can cause disorientation and eventually death. These chemicals have been found in large amounts in pollen, which is the bees main protein source. After doing more research on CCD, they found that more than 170 different chemicals in bees from the affected hives, including fluvalinate and coumaphos, are commonly used by beekeepers to combat varroa mites. Another source from EBSCO says that growing evidence has suggested that neonics disrupt the normal functioning of bees, making them more vulnerable to ailments that eventually lead to death. They say that more than 90 commercial crops in the U.S. rely on pollinators like bees as well.Another article on EBSCO says that Managed honey bee colonies in the United States have dropped by about half since shortly after World War II, and a parasitic mite that arrived in the late 1980s virtually eliminated feral colonies. Though normal attrition of hives over the winter was once about 5 percent, the die-off of honey bees has been around 30 percent each year from 2007 through 2010, according to Agriculture Department surveys.
