      abstract = {In the past few years, there has been a significant  decline in number of managed honey bee colonies, as well as  perhaps unmanaged colonies, in parts of the western  hemisphere. Plant pollination by honey bees is valued at  billions of dollars to world economies. Therefore, external  threats to honey bees can have serious implications on  global food supplies. Several important threats are the  parasitic bee mites, Varroa jacobsoni (Oudemans) and  Acarapis woodi (Rennie), and chemical pesticides. Some  efforts to combat these threats include breeding bees for  mite resistance, using chemical treatments for mite  control, selecting chemical pesticides less hazardous to  bees, and exploring non-chemical alternatives for pest  control.},
