Editing Buzz pollination (section)

==Economic impacts==
Scientists can now import pollinators, such as bumblebees, where there might be a shortage of pollinators. In New Zealand, the [[red clover]] plant population was restored when bumblebees were imported from Europe to help with the pollination. Maintaining red clover population in New Zealand at the time was critical to the country's crop production rate. However, in North America, the managed honeybee industry experienced decline in the early 2000s due to [[colony collapse disorder]]. This has led to higher expenses for farmers from the east to the west coast of the United States and Canada to help pollinate almonds, cucumbers and certain seed plants.<ref name=":0">{{Cite journal|last1=Peter|first1=Kevan|last2=Truman|first2=Phillips|date=2001-04-05|title=The Economic Impacts of Pollinator Declines: An Approach to Assessing the Consequences|journal=Conservation Ecology|language=en|volume=5|issue=1|doi=10.5751/ES-00272-050108|issn=1195-5449|hdl=10535/3353|url=http://dlc.dlib.indiana.edu/dlc/bitstream/handle/10535/3353/http___www.ecologyandsociety.org_vol5_iss1_art8_.pdf?sequence=1&isAllowed=y|hdl-access=free}}</ref>

One of the most common plants that are assisted by buzz pollination is the tomato (''[[Solanum lycopersicum]]''). In greenhouses worldwide, up to 50 bumblebee colonies are used per hectare during growing season, bringing in values of approximately €13 million a year for a 40,000 hectare globally. Due to competition between producers and an increase in success rate of rearing, the total costs for the bumblebee colonies have diminished severely. This common practice has led to producers branching out and selling not only bumblebees but other insects who may have [[Mutualism (biology)|mutualistic]] relationships with plants. The total profit of this industry has been recorded to produce over €111 million a year, with €61 million coming in from bumblebees alone.<ref name="Velthuisvan Doorn2006">{{cite journal|last1=Velthuis|first1=Hayo H.W.|last2=van Doorn|first2=Adriaan|title=A century of advances in bumblebee domestication and the economic and environmental aspects of its commercialization for pollination|journal=Apidologie|volume=37|issue=4|year=2006|pages=421–451|issn=0044-8435|doi=10.1051/apido:2006019|doi-access=free}}</ref>
