Preliminary Report On Selection And Breeding Of Honeybees For Alfalfa Pollen Collection, William P. Nye, O. Mackensen
Preliminary Report On Selection And Breeding Of Honeybees For Alfalfa Pollen Collection, William P. Nye, O. Mackensen
All PIRU Publications
Some colonies of honeybees on alfalfa collect a much higher percentage of alfalfa pollen than others. The possibility of genetic differences between colonies was investigated. Colonies collecting high and low percentages of alfalfa pollen were first selected. Daughters of queens from three 'high' and three 'low' colonies were inseminated from their brothers, and colonies headed by queens of these six lines were tested. Colonies headed by sister queens were more similar in the proportion of alfalfa pollen they collected than were those headed by unrelated queens. This suggests heritability of the factor studied. On the other hand no correlation was …

A Revisional Study Of The Bees Of The Genus Perdita F. Smith, With Special Reference To The Fauna Of The Pacific Coast (Hymenoptera, Apoidea) Part V, P. H. Timberlake
A Revisional Study Of The Bees Of The Genus Perdita F. Smith, With Special Reference To The Fauna Of The Pacific Coast (Hymenoptera, Apoidea) Part V, P. H. Timberlake
All PIRU Publications
In parts III and IV of this revision the species of the typical subgenus of Perdita belonging in the zonalis, halictoides, and octomaculata groups have been treated. This study is now extended to include the species belonging in that section of Perdita which may be called the ventralis group. In order to facilitate the study of these bees a key to the groups treated in Part III and subsequent parts is here offered. This key may afford some help in classifying the more typical members of the groups, but because of the multiplicity and extreme diversity of these …

Observations On The Behavior Of Bees In A Controlled-Environment Room, William P. Nye
Observations On The Behavior Of Bees In A Controlled-Environment Room, William P. Nye
All PIRU Publications
A detailed description is given of a controlled-environment flight room for the study of bee behaviour both in and outside the colony. Experiments demonstrated the ability of a colony to collect pollen, sugar syrup and water in the room, and to rear brood normally, increasing its strength throughout It months in spring. The behaviour of bees collecting powdered pollen from a tray 30 ft. [10 m.l from the hive was influenced by the amount and distribution of light in the room.

Alfalfa Seed Production Studies, M. W. Pedersen, William P. Nye

From a practical standpoint, the culture to use is the one that gives the greatest net return. The study indicates that planting alfalfa for seed production in 24-inch rows at a rate of 1.5 pounds of seed per acre and thinning in the fall of the year after planting is best. For example, a field planted in the spring of 1963 should be thinned in the fall of 1964. Cutting out approximately every other foot within the row seems advisable. While there appears to be considerable latitude in the extent of thinning, weed problems are encountered if the stand is …

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 …
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 …

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
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 …
