Several entomological techniques were combined to create a reliable method of analyzing the foraging activities of colonies ofApis melliferaL. Returning bees were periodically sampled at the hive entrance with a sweep net. Vacuum sampling from a modified auger-hole pollen trap is proposed as a means of reducing possible sampling error. The samples of bees were quick frozen in sealed plastic bags and held for subsequent laboratory analysis.The percentage of foraging bees (pollen, nectar, and both pollen and nectar collectors combined) and of nonforaging bees remained constant at all times over all days, but the ratio of nectar to pollen-collecting bees varied; an increase in one was reflected by a decrease in the other. The ratio of bees collecting both pollen and nectar to those collecting only pollen was approximately 1:3 Statistical analysis demonstrated that duplicate samples of 10 bees produced adequate data for differentiation between the foraging activities of worker bees.
