Pollination & Field Trials

About Pollination and Field Trial Services:

Pollinator testing capabilities include laboratory-based studies, semi-field, and field exposures.

Smithers Viscient’s Pollination and Field Trial Services Expertise:

Smithers Viscient conducts field pollinator studies throughout the United States with permanent locations on the East and West coast. Our North Carolina facility is the base of operations for pollinator health effects and residue/exposure studies. Our California facility, located in the San Joaquin valley in Fresno, California was a 2015 expansion, allowing for staff to be readily available for field studies that must be conducted in California under EPA/CDPR recommendation.

Preliminary Field:

  • Bee Matrix Residue Studies – initial assessment of risk (fits between laboratory and semi-field)
  • May be conducted in any state that allows for agricultural practices that meet study requirements. Normally California, North Carolina and one additional state
  • Nectar and Pollen can be hand sampled or collected by the appropriate pollinator species
  • Can collect matrices of leaves, soil, flowers, whole plants, fruits, nectar, pollen, bee bread, stored nectar, pollen baskets, royal jelly, and larvae, depending on study design
  • Experience with a variety of agricultural commodity crops, including cranberries, blueberries, pumpkins, cotton, cucumbers, melons, tomatoes, almonds, citrus, and apples. Full list available upon request
  • Possibility of soil, foliar, or chemigation applications
  • Analytical Chemistry can be completed in-house, even at low levels
  • Methodology must be established prior to sample analysis


Semi-Field Studies:

Colony Feeding Studies

  • OCSPP 850.SUPP
  • Colony Condition Assessments may be done visually or digitally, depending on location
  • Varroa, Nosema monitoring
  • Weight data collected continuously
