All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The alfalfa weevil, Hypera postica (Gyllenhal), was first found in the United States in Salt Lake City, Utah, during 1904 (Titus, 1910b). It spread form this point of original introduction and partially infested Cache Valley by 1912 (Titus, 1913).

Utah ranks as one of the major producers of alfalfa seed in the nation. In 1964, 6.02 million pounds of cleaned seed were produced in the state. This resulted in an income of 1.7 million dollars to Utah seed producers for that year (Agricultural Statistics, 1965).

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 …

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
The four-spotted spider mite, Tetranychus canadensis (McGregor) has been identified from parts of seventeen states, Washington, D. C., and Danada since it was first recognized as a new species by McGregor (1950) from Ontario, Canada. During this thirteen-year period it has been reported on at least twenty-eight different host plants including ornamentals and orchard, vegetable, and forage crops.

Cuterebra (Diptera: Cuterebridae) Of Utah And The Neighboring States, Charles L. Graham
Cuterebra (Diptera: Cuterebridae) Of Utah And The Neighboring States, Charles L. Graham
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Cuterebra are robust flies, which in flight resemble large black bees. Little is known about the bionomics of most of the species included in this genus. Nearly all members of this group parasitize rodents and lagomorphs. Some species have a wide host range, others seem to be specific or semi-specific to a single host. Accidental parasitism of animals other than specific host animals does occur. In such cases the larvae or the host usually die before the larvae can mature. There is a wide variation in the effect of of the parasite on its host. If the parasite is found …
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 …
