Biology And Control Of Mcdaniel Mite, Tetranychus Mcdanieli Mcg., In Utah, Gerald L. Nielsen

Biology

Mites are the cause of untold damage to agriculture each year. Some of these mites, such as the clover mite, are fairly well known to the general public. They often invade our homes and injure our crops. We find many species of mites in our gardens on vegetables and ornamentals; however, they are often overlooked as the cause of the damage. This is possibly due to the small size of the mites and to the fact that they frequently assume the color of the leaves upon which they are feeding.

The Relative Influence Of The Reaction In Immune Calves On The Sexual And Asexual Stages Of Eimeria Bovis, Richard A. Heckmann

Biology

Coccidiosis has been listed as the third most important parasitic disease in cattle (13). Foster in 1949 estimated that this disease is responsible for an annual loss of ten million dollars in the cattle industry and he believed that the economic loss is at least as great as that caused by coccidiosis in poultry (17). Bovine coccidiosis kills many calves before they are six months old. Only rarely are cattle found free of coccidia (26). According to Gibbons and Baker (18) the mortality has been estimated as high as 29.3 percent in several outbreaks of bovine coccidiosis.

Continuous Low Level Treatment Of Calves With Sulfabromomethazine As A Means Of Controlling Coccidiosis, Glen W. Clark

Biology

Coccidiosis is a protozoan disease. It is produced by small, one-celled organisms of the genus Eimeria. Eleven species have been reported in cattle in this country (11). At least two species, E. bovis and E. zurnii are known to be pathogenic to cattle (21).

Insect Transmission Of The Virus Causing Little Cherry Disease, Walter H. A. Wilde

Biology

The disease known as little cherry was first reported as seriously affecting sweet cherry plantings by diminishing size, color, and taste of mature fruits in 1933 (3) at Willow Point on the West Arm of Kootenay Lake in the Kootenay District of British Columbia (figure 1). In 1937, Milbrath (13), Plant Pathologist for the state of California, surveyed the little cherry area in the Kootenays to determine the relationship, if any, that little cherry might have with known stone fruit virus diseases of the U. S. A. His report stated little cherry disease did not resemble the California "buckskin" cherry …

Immunology Of Coccidiosis Caused By Eimeria Bovis In Calves, Clyde Merle Senger

Biology

Coccidiosis is a disease which can occur in most vertebrates and certain invertebrates as a result of infection by organism classified in the Order Coccidia of the Class Sporozoa, Phylum Protozoa. Host animals become infected by ingesting the exogenous resistant stage, the oocyst (Figures 1 and 2). These oocysts may be ingested with contaminated food and water or from the bodies of other animals. In the intestine of the new host, the oocysts rupture and release a specific number of sporosoites depending upon ths genus of coccidia involved. The liberated sporesoites penetrate epithelial or other cells of the intestine and …

The Effects Of Soil Moisture Condition On Injury To Plants By Hydrogen Fluoride, Orin D. Anderson

Biology

Injury to plants associated with fluorides was first noted about 25 years ago by investigators in Germany. Since that time, and with increasing industrialization of certain areas of the world, this physiological disease has become very Important economically. Fluorides have caused considerable loss to certain crops and to livestock that eat forage containing fluorides in toxic quantities. Johnson (1952) has estimated that the annual loss due to air pollution in the United States total $1,500,000,000 or $10 per capita and that the government and industry are spending about $100,000,000 each year to combat damages. The amount of this damage that …

Some Effects Of Aldrin, Chlordane, Dieldrin And Heptachlor On The European Earwig, E. Fred Legner

Biology

During the past 15 years the European earwig (Forficula auricularia L.) has assumed the number one position as a general pest to home owners in Utah. It has spread to nearly every corner of the state where environmental conditions are suitable for its growth, and agricultural agents in certain Utah counties have received more complaints concerning earwigs than any other insect pest. This recent interest in earwigs has resulted in many suggestions and recommendations as to the most effective means of control.

A Cytological Study Of Agropyron Dasystachyum, Bert W. Winterton

Biology

This study is concerned with the meiotic chromosome behavior of Agropyron dasystachyum (Hook.) Scribn., commonly known as thickspike wheatgrass. Detailed analyses of the pollen mother cells have been made in an attempt to establish the degree of chromosome pairing, occurence of univalents and multivalents, chromosome laggards, micronuclei, and other chromosomal irregularities. These data should provide evidence regarding the type of polyploidy present in this species and indirectly in Agropyron albicans.

The Typing Of Staphylococcal Isolates From Turkey Epizootics, William R. Thornley

Biology

Utah has been confronted with the problem of turkey synovitis becoming epizootic in certain areas of the state. This is a crippling disease of turkeys causing considerable loss among birds soon after they are placed on the range. Because much of the expense of brooding and rearing has already been encountered by the growers, the loss is often severe.

A Study Of The Sequence Of The Professional Education Program For Elementary School Teachers At Utah State University, Christopher Lee Colston

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Education, like any other profession, is responsible for constant improvement. The professional teacher education institutions are constantly looking for ways of improving professional teacher education programs. The course sequence of the teacher education program is an area for continual improvement. Every teacher educator has a theory as to what is the best teacher education program and what is the best sequence for this theory program. The literature has revealed very little in the area of a sequence for the teacher education program.

The Effect Of Certain Fluoride Sprays In The Production Of Soft Suture On Peaches, N. V. Narayanamoorthy

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Pollution of the atmosphere and its potential deleterious effects on health, industry, agriculture and natural resources are causing grave concern in many parts of the world. In the past century there has developed in the fields embraced by physical and biological sciences a considerable knowledge of theoretical and applied information, serving as a versatile tool in combating such problems. Air pollution problems seem to have gained much attention with the rapid development of various industries in major parts of the world. Rural and urban areas adjoining these industrial locales are confronted with the dangerous overall problems of air pollution. Evidently, …

Chlorophyll And Productivity In A Mountain River, William J. Mcconnell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Investigation of primary production in streams and rivers has lagged behind similar investigations in marine and lacustrine environments. Recently, however, Odum (1956) has demonstrated methods that allow the estimation of productivity of most moving waters. For reasons discussed later in this paper, Odum's method is not satisfactory for shallow, very rapid rivers as typified by Logan River. The present investigation then was primarily an exploration of a method possibly applicable to measurement of productivity in shallow rapid rivers.

Investigations of phases of the ecology and distribution of the main contributors to primary production, the benthic algae, was a necessary corollary …

The Phytoplankton Of The Logan River, Utah, A Mountain Stream, William J. Clark

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The voluminous limnological literature contains few studies of mountain streams. Though there are a few papers on the benthic algae (see Budde 1928, Raabe 1951) only Pennak (1943) reports year-round quantitative data on the phytoplankton. Brinley (1950) gives some phytoplankton information in a summer study of streams in Rocky Mountain National Park.
