Abstract or Summary
  • Limnanthes alba, commonly known as meadowfoam is a popular commercial crop because its seed oil is composed of long carbon chains that provide it with high oxidative stability and consequently make it a desirable ingredient in cosmetic products. As a commercial pollinator, the western honey bee, Apis mellifera, may be utilized to pollinate monocultures such as L. alba. The pollen fidelity of a pollinator with regard to its intended crop determines the efficiency and overall benefit of the pollinator’s presence in the field. This research examines pollen fidelity of A. mellifera with regard to L. alba in a commercial setting. The average L. alba proportion of total trapped pollen was determined to be 88.5%. The high fidelity of A. mellifera to L. alba suggests that it was beneficial to have a supplemental pollinator present, but to definitively determine that a comparative study would need to be performed.
