Sugar dataset final.xlsx

Single source white clover (Fabaceae: Trifolium repens) pollen pellets collected by Apis mellifera purchased from Ames Farm (Watertown, Minnesota, USA; www.amesfarm.com) and single source rose (Rosaceae: Rosa spp.) pollen collected by Apis mellifera purchased from the China Health Club (Chongqing, China; www.teaherbalshop.com) were used to create artificial diets to raise C. calcarata eggs. Pollen identity and purity were based on vendor claims. Sugar samples were thawed in 50°C water bath for 3 min and then centrifuged at >2,500 rpms for 5 min. Sugar content was measured in degrees Brix by placing 20 mL of the supernatant on a handheld refractometer. Based on the weight of the original pollen ball, we determined the milligrams of sugar in each sample.
