Pollen Collection From Alsike Clover By High And Low Alfalfa Pollen Collecting Lines And By A Commercial Line Of Honey Bees, William P. Nye
Pollen Collection From Alsike Clover By High And Low Alfalfa Pollen Collecting Lines And By A Commercial Line Of Honey Bees, William P. Nye
All PIRU Publications
The collection of alsike clover pollen by high alfalfa pollen collecting (APe) and low alfalfa pollen collecting lines of honeybees and by bees from commercial colonies were compared at Donnelly, Idaho, U.S.A., in an area where alsike clover was flowering. All three lines collected an overwhelmingly high percentage of alsike clover pollen (92-99 %), and there were no significant differences between them. A limited amount of rape pollen was collected every day by all groups, and also a small amount of dandelion pollen on one or two days. Only one (high APC) colony collected pollen from a small nearby field …

Management Of Honeybee Colonies For Pollination In Cages, William P. Nye
Management Of Honeybee Colonies For Pollination In Cages, William P. Nye
All PIRU Publications
The use of bees for pollination is extending in various directions, and each extension brings with it new problems to be solved. Infields and orchards, the main problem may be to get the bees to visit all the flowers. In a small plot, this can be ensured by enclosing the plot and a hive of bees in a cage, but special steps are then needed to ensure the well-being of the bees. In this article Mr. Nye, who is on the staff of the Entomology Research Division of the United States Department of Agriculture, describes the colony management necessary. The …
Nectar Sugar Concentration As A Measure Of Pollination Of Alfalfa (Medicago Sativa L.), William P. Nye, M. W. Pedersen
Nectar Sugar Concentration As A Measure Of Pollination Of Alfalfa (Medicago Sativa L.), William P. Nye, M. W. Pedersen
All PIRU Publications
The "visitation rate of honeybees on alfalfa may possibly be measured by determining the sugar concentration of nectar in the honey stomachs of foraging bees. This concentration is shown to be largely controlled by the relative humidity and the time available for nectar evaporation in the alfalfa blossom, which in turn depends on the rate of visitation by honeybees. An adjustment for relative humidity may be necessary in order to compare readings widely separated in time or location. Where conditions are relatively constant from day to day, it may be sufficient to measure the nectar sugar concentration and relative humidity …

Insect Pollinators Of Carrots In Utah, George E. Bohart, William P. Nye
Insect Pollinators Of Carrots In Utah, George E. Bohart, William P. Nye
All PIRU Publications
IN THE course of observation at Logan, Utah, on the occurrence and pollinating activities of insects on carrots grown for seed, 334 species representing 71 families, were collected. Most numerous in species were the hymenopterous families and superfamilies Sphecidae, Apoidea, Psammocharidae, Vespidae, and Ichneumonidae, and the dipterous families Syrphidae, Tachinidae, Bombyliidae, Stratiomyidae, and Sarcophagidae. Most numerous in individuals were the dipterous families Syrphidae, Ceratopogonidae, Chloropidae, and Piophilidae and the coleopterous family Coccinellidae. Families and superfamilies represented by the most efficient pollinators were Apoidea, Sphecidae, Syrphidae, and Stratiomyidae. Abundance times efficiency was used as a pollination index for each species. On …
Distance From The Apiary As A Factor In Alfalfa Pollination, M. D. Levin, George E. Bohart, William P. Nye
Distance From The Apiary As A Factor In Alfalfa Pollination, M. D. Levin, George E. Bohart, William P. Nye
All PIRU Publications
Experiments conducted in northern Utah indicated that the distribution of honey bees (Apis mellifera L.) on an alfalfa field is modified by various influences besides distance from the colonies. Because of these other factors, generalizations concerning the effect of distance from colonies on the distribution of foraging honey bees cannot be made on the basis of experiments herein reported. A slight negative relationship between bee populations and distance from colonies in alfalfa fields was found in some of the experiments reported. In two fields where the distance was less than 600 feet, horizontal stratification of the field population …
