Importance of bee pollination for cotton production in conventional and organic farms in Brazil

By Viviane C. Pires et al.

Cotton production is not entirely dependent on insect pollination, but can be increased by bee visits to the cotton flower. In Brazil, this bee-generated yield increase is poorly studied and, for this reason, is ignored, especially in conventional plantations. In this production system, soil preparation is mechanized and insecticide is intensively employed, especially during flowering. These practices reduce bee nesting and foraging in and around the cotton fields, and bee benefits may not be noticeable. On the other hand, in organic farms, where mechanization and insecticide use are minimized, the yield increase promoted by bees is evident and helps making this production system economically viable for smallholding.
