Chagas Disease And Vectors In North Central Texas, Joe C. Elkins Apr 1951

Chagas Disease And Vectors In North Central Texas, Joe C. Elkins

Field and Laboratory

All members of the large hemipterous family Reduviidae are predacious, but only members of the subfamily Triatominae feed exclusively on vertebrate blood. Readio (1927) noted that Mr. J. R. Lembert observed the common Pacific Coast species of Triatoma feeding on carrion and excrement. Lutz (1918) reported that Triatoma sanguisuga LeConte feeds on insects, including grasshoppers and potato beetles. Apparently neither of the above accounts illustrate normal feeding habits.

Ecological Studies In A Midwestern Range: The Vegetation And Effects Of Cattle On Its Composition And Distribution, J. E. Weaver, G. W. Tomanek Apr 1951

Ecological Studies In A Midwestern Range: The Vegetation And Effects Of Cattle On Its Composition And Distribution, J. E. Weaver, G. W. Tomanek

Department of Agronomy and Horticulture: Faculty Publications

There is continued need for a better understanding of range vegetation and its use by range animals. Range preservation and improvement in the midwest are largely matters of wise use and proper management of our natural grasslands. A more comprehensive understanding of the range itself is needed--its forage, soil, and water supply, and factors influencing a proper distribution of livestock. The degree of utilization of forage that will result in the maintenance of excellent or good range condition and the improvement of a range in fair condition should be ascertained. Soil conservation on range lands is accomplished primarily by improvement …


Weed Control In Lawns And Gardens, Leonard L. Schrader, Soloman Cook Mar 1951

Weed Control In Lawns And Gardens, Leonard L. Schrader, Soloman Cook

SDSU Extension Circulars

Weeds. are a problem in the city, small town and around the farm home, just as they are a problem in pastures, hay lands and tilled fields. Wherever weeds grow, they are an unsightly and expensive nuisance. In the vacant or untended lots m town, weeds become the source of seed that will spread to surrounding gardens, lawns and farm fields. Hampered vision at intersections, caused by rank-growing weeds, has contributed to many traffic accidents. In addition, they sap the soil's fertility, which probably is sent up in smoke when the weeds are burned in the fall. In gardens, they …

Hairy Vetch For Nebraska, T. H. Goodding Feb 1951

Hairy Vetch For Nebraska, T. H. Goodding

Nebraska Agricultural Experiment Station: Historical Circulars

Hairy vetch is a winter annual legume. It may be planted either in the spring or fall. Hairy vetch often succeeds on soils where sweet clover and alfalfa fail. It is more tolerant to acid (lime-deficient) soils than most leguminous crops.

Increase Of Poison-Bitterweed (Hymenoxys Odorata) On Texas Range Lands, V. L. Cory Jan 1951

Increase Of Poison-Bitterweed (Hymenoxys Odorata) On Texas Range Lands, V. L. Cory

Field and Laboratory

This paper, as read before the Texas Academy of Science, was titled "Increase of Native Weedy Forbs on Texas Range Lands." The reason for the change of title here is that, from a range standpoint, not all forbs are weeds and not all weeds are forbs. Forbs are herbaceous plants that are not grasses or grass-like plants. Some of the forbs are toxic to livestock or so unpalatable to them they feed upon them only when excessively hungry or starving. In reality some of these range forbs are forage plants and some are not.

Cinderella Furniture, Isabel Mcgibney Jan 1951

Cinderella Furniture, Isabel Mcgibney

SDSU Extension Circulars

With an elaborate gilt coach that had once been a pumpkin, and glass slippers that didn't disclose their former identity, a common colorless girl became a famous storybook beauty. With a wave of the magic legendary wand, the good fairy transformed the unattractive into the desirable, the ugly into the beautiful and the rundown into the useful. Today a woman is her own fairy. The magic wand that makes the old as good as new is imagination, ingenuity and know-how. Like the two chairs on the cover that Mrs. Homemaker proudly shows her family, the unattractive chair has completely changed …


The Utilization Of Food Elements By Growing Chicks. Xiii. The Effect Of Additions Of Dehydrated Alfalfa Meal To High Corn Chick Rations, C. W. Ackerson, R. L. Borchers, F. E. Mussehl Jan 1951

The Utilization Of Food Elements By Growing Chicks. Xiii. The Effect Of Additions Of Dehydrated Alfalfa Meal To High Corn Chick Rations, C. W. Ackerson, R. L. Borchers, F. E. Mussehl

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Feeding trials were conducted on three groups of chicks in eight lots receiving a growing mash containing dehydrated alfalfa meal at levels of 2, 3, 4, 5, 6, 9, 10, 12, and 15 per cent. Comparisons were not made simultaneously but no general trend toward growth depression was evident in comparable lots. In addition duplicate trials of four lots of newly hatched New Hampshire chicks were made on pelleted rations carrying 0, 2, 4, and 6 per cent of a good quality dehydrated alfalfa meal. The chicks were all fed accurately known amounts of the pelleted rations for six weeks. …

A Study Of Bovine Noseprints, Morris W. Hirsch Jan 1951

A Study Of Bovine Noseprints, Morris W. Hirsch

Electronic Theses and Dissertations

The breed association are continuously confronted with the problem of properly identifying animals for registration. The method of identifying the broken color breeds, such as Guernseys, Holsteins, and Ayrshires, is by a sketch of the color patterns which accompanies the application for registration. This has been fairly successful, but due to the poor drawing ability of the applicant approximately twenty percent of animal markings and sketch do not resemble each other to establish identity. The solid colored breeds use brands or tattoo marks in the ear which are not entirely satisfactory since these are artificial and can be applied in …


The Affect Of Indole-3-Acetic Acid On The Fission Rate Of Paramecium Caudatum, Margherita L. Baker Jan 1951

The Affect Of Indole-3-Acetic Acid On The Fission Rate Of Paramecium Caudatum, Margherita L. Baker

Student Scholarship

This research report, authored by Margherita L. Baker in 1951, investigates the physiological effects of the plant growth hormone indole-3-acetic acid, also known as heteroauxin, on the fission rate of the protozoan Paramecium caudatum. The study is grounded in the hypothesis that if plant hormones can influence animal growth, it suggests a fundamental similarity in the growth mechanisms between the two kingdoms. The experimental procedure was divided into two distinct series to observe how varying environmental conditions and food availability influenced the hormonal impact. 

In the first series, paramecia were maintained in a nutrient-rich beef extract medium with an abundant …


The Bionomics Of The Culicidae Of The Dallas Area, Ottis L. Mccleskey Jan 1951

The Bionomics Of The Culicidae Of The Dallas Area, Ottis L. Mccleskey

Field and Laboratory

Little work has been done on Texan mosquitoes. In 1922 Dyar listed 43 species from Texas, 10 of which were recorded from near Dallas. Cushing (1934) listed the mosquitoes of Brazos County. McGregor & Eads (1934) in their work on the mosquitoes of Texas, divided the State into 17 approximately equal areas. They gave a total list of 54 species, of which 19 were reported from the area that included Dallas County. Fisk & LeVan (1941) published notes on the mosquitoes of Brownsville. The State Health Department of Texas published (1944) a booklet, "The Mosquitoes of Texas", which is the …

The Sedimentation Rate Of Potato Yellow-Dwarf Virus, M. K. Brakke, L. M. Black, Ralph W. G. Wyckoff

Department of Plant Pathology: Faculty Publications

BLACK et al. (1948) have published electron micrographs of bodies believed to represent the New York variety of potato yellow-dwarf virus (Aureogenus vastans (H) Black) (Holmes 1948). The photographs showed bodies in several different extracts of infected plants of Nicotiana rustica L., but not in corresponding preparations from healthy plants. Similar bodies were found in concentrates from plants infected with the New Jersey variety of the virus (var. agalliae Black). These bodies were larger than, and of a different character from, those of plant viruses hitherto examined in the electron microscope. The present study was undertaken to obtain evidence …


Enemies Of Aspen, Clyde M. Christensen, Ralph L. Anderson, A. C. Hodson, Paul O. Rudolf Jan 1951

Enemies Of Aspen, Clyde M. Christensen, Ralph L. Anderson, A. C. Hodson, Paul O. Rudolf

Aspen Bibliography

So long as aspen was considered primarily a weed species, there was little concern over the enemies which might injure or destroy it. Sometimes these enemies were actually considered "blessings in disguise. Now, however, that aspen not only is the most abundant "but also one of the most widely utilized tree species in the Lake States, there is increasing interest in anything that may affect its future supply. For that reason this brief summary of information on the enemies of aspen has been assembled.

Hydatid Disease (Echinococcosis) In Alaska And The Importance Of Rodent Intermediate Hosts, Robert L. Rausch, Everett L. Schiller Jan 1951

Hydatid Disease (Echinococcosis) In Alaska And The Importance Of Rodent Intermediate Hosts, Robert L. Rausch, Everett L. Schiller

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Hydatid disease, caused by the larval form of a tapeworm, Echinococcus granulosus (Batsch, 1786), is of circumpolar distribution, but has not previously been considered to be of much public health significance in North America. It is the purpose of this paper to present observations on this disease in Alaska, with special reference to its transmission to humans.


Biotic Interrelationships Of Helminth Parasitism, Robert L. Rausch Jan 1951

Biotic Interrelationships Of Helminth Parasitism, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Biotic interrelationships in Alaska have so far suffered little from man's attempts to improve upon nature. As a result of these favorable circumstances, biological investigation in Alaska offers unusual opportunity for elucidating problems which can no longer be approached in the more populated parts of North America. One is very fortunate to have the opportunity of working under these conditions, since present trends indicate that Alaska is soon to go by the way of the great wildernesses which once existed in the United States and Canada.


The Status Of Beavers In The Delta Area Of The San Joaquin River, San Joaquin County, California, 1950-1951, Delbert David Cram Jan 1951

The Status Of Beavers In The Delta Area Of The San Joaquin River, San Joaquin County, California, 1950-1951, Delbert David Cram

University of the Pacific Theses and Dissertations

The term “delta area” refers to a region roughly 40 miles long and 15 miles wide situated 65 miles east of San Francisco Bay where the San Joaquin and Sacramento Rivers join and enter Suisun Bay. The waterways in this area are fresh water from these rivers, but they are affected by the ocean tides and to some extent by the salinity of the ocean water. The rgeion ecompasses about 507,000 acres, most of which has been reclaimed for agricultural purposes by the construction of levees to contain the tides and high waters. The word “islands” is used locally to …
