Significant Developments In European Corn Borer Research1,2, T. A. Brindley, F.F. Dicke

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Since its identification as an introduced pest in 1917, the European corn borer, Ostrinia nubilalis (Hilbner), has been investigated under widely different environmental conditions. During the first decade, the research was directed largely toward studies on biology and the development of control measures that were cultural, biological, and mechanical in nature. The important initial objective was a delaying action to reduce popula­tions in the infested areas, thereby impeding the spread to the central Corn Belt. Legislation was enacted making it compulsory for growers to practice stipulated population-reducing measures. The spread west and south and the economics of harvesting and cultural …

Development Of Systemic Insecticides For Pests Of Animals In The United States1, R.C. Bushland, R.D. Radeleff, R.O. Drummond

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The first encouraging results in the search for systemic insecticides were obtained in 1944 by Lindquist and his co-workers (53), who found that bed bugs, Cimex lectularius Linnaeus and C. hemipterus (Fabricius), died after feeding on rabbits treated orally with DDT or pyrethrins. In 1946, Knipling and associates (48) treated rabbits with oral and intravenous dosages of insecticides,and reported that rabbits tolerated treatments of lindane and 2 -pivalyl-I,3-indandione at rates that were lethal to mosquitoes, Aedes aegypti (Linnaeus), and human body lice, Pediculus humanus humanus Linnaeus when feeding on the rabbits. These findings, made at the Orlando, Florida, laboratory of …

Some Characteristics Of A Purified Heat-Stable Aldolase, P.J. Thompson, T.L. Thompson

Papers in Microbiology

THOMPSON, P. J. (University of Nebraska, Lincoln) AND T. L. THOMPSON. Some characteristics of a purified heat-stable aldolase. J. Bacteriol. 84:694-700. 1962-Aldolase from a thermophilic strain of bacteria was obtained in a state of high purity. Heat studies of purified aldolases from cells cultivated at 45 and 65 C showed them equally stable at 70 C for 1 hr. Metal-ion and chelate studies indicated that thermal aldolase is metal ion-independent. Carboxypeptidase did not alter activity or specificity. The enzyme was specific for fructose- 1, 6-diphosphate. Hydrazine was found inhibitory in the assay procedure. The inhibition was independent of pH over …

Translocation Of Coumarin Across A Graft Union M Sweetclover, Herman J. Gorz, Francis A. Haskins

Department of Agronomy and Horticulture: Faculty Publications

Despite several recent investigations of the biosynthesis of coumarin and related compounds in sweetclover, little is known of the site or sites within the plant at which coumarin is formed. Weygand and Wendt reported coumarin formation in root cultures of Melilotus officinalis (L.) Lam. when suitable precursors were supplied. Mothes and Kala concluded that scopoletin and umbelliferone, compounds closely related to coumarin, can be synthesized by root cultures of Atropa belladonna L. The experiments cited gave no indication that the roots are the preferred site of synthesis or that synthesis takes place at all in the roots of intact plants. …

Negro College Students' Participation In Sit-Ins, Ruth Searles, J. Allen Williams Jr.

Department of Sociology: Faculty Publications

Socioeconomic and legal changes in the position of southern Negroes have been accompanied by a changing pattern of race relations and a new attitude on the part of Negro leaders. Data from a closed-answer questionnaire administered to students in three Negro colleges in North Carolina support the hypothesis that sit-in protests are less indicative of social alienation among Negroes than of their identification with or positive reference to the white middle class.

Concluding Remarks Of Appreciation With Comments On Histoplasmosis And Cryptococcosis, Philip J. Spear

Vertebrate Pest Conference Proceedings: 1st (1962)

The record of this meeting will stand as a permanent tribute to Dr. Walter Howard and his associates. It should remind them for years to come of their worthwhile contribution in conceiving, organizing, promoting, and handling the details of this first Vertebrate Pest Control Conference. Those of us privileged to attend will be grateful for the opportunity to enlarge our acquain¬tance with the workers in the vertebrate pest control field, and to share in this exchange of information. The National Pest Control Association, whose members provide among other services, control of many vertebrate pests, draw information and guidance from many …

Infectious Disease Hazards To Pest Control Operators, Paul Arnstein Dvm, Mph

Vertebrate Pest Conference Proceedings: 1st (1962)

One of the primary reasons for controlling most vertebrate pests is the role these creatures play as links in the infection chain of certain agents pathogenic to man. It is reasonable to assume that the persons engaged in the eradication or removal of pests are at some risk of contacting zoonoses - diseases transmissible from animals to man. Unfortunately, histories or epidemiological data of occupational infections among pest control operators are not available; perhaps this society may become a future assembly point for statistics in this field. The hazards therefore have to be approached theoretically: diseases known to be associated …

Meeting The Meadow Mouse Menace, William D. Fitzwater

Vertebrate Pest Conference Proceedings: 1st (1962)

The orchardist has many ways to lose money but one of the best is to ignore his mouse problem. This apparently insignificant, short-tailed little rodent by his unobtrusive but systematic attacks on the growing tissue of trees can be very expensive. The Indiana Extension Horticulturist has stated that mice are the number one cause for orchardists going out of business in recent years in that State. Moreover, the problem is not a recent one as a questionnaire to county agricultural agents in 1924 (Davis, 1925) showed that field mice were even then considered a problem in 40 per cent of …

Mole And Woodrat Control, Rex E. Marsh

Vertebrate Pest Conference Proceedings: 1st (1962)

MOLES: In regions where moles thrive, lawns in golf courses, parks, cemeteries and home yards are often made unsightly by dirt mounds and ridges pushed up by the active little animals. In cultivated land, moles may cause consider¬able economic loss through their burrowings. Mole control can be divided into six basic categories: exclusion, repellents, gases, toxic baits, reduction of food supply, and trapping. Un¬changed over the years, trapping is still considered the most reliable of all methods of control, however, under certain conditions or situations, the other methods of control may be extremely useful. WOOD RATS: The native wood rat …

Application Of Oscillographic Polarography To Determination Of Organic Phosphorus Pesticide Residues, Raymond J. Gajan

United States Food and Drug Administration: Publications

Some organic phosphorus pesticides have been determined successfully by polarography (1-7). However, in most cases the methods were used to determine the pesticide in commercial formulations. Little has been reported on the polarographic determination of microgram amounts of these pesticides such as those encountered in pesticide residue analysis.

Many of the methods used for the determination of these pesticides are nonspecific. They are based on cholinesterase assay (8- 12), radioactive tracer analysis (13, 14), total phosphorus (15-17), and paper chromatography (18-24).

In this paper we will discuss the polarography of Systox, Di-Syston, and· Thimet and some of their oxidation products, …

Malic Dehydrogenase Activity At 101 C Under Hydrostatic Pressure, Richard Y. Morita, Roger D. Haight

Papers in Microbiology

MORITA, RICHARD Y. (University of Nebraska, Lincoln) AND ROGER D. HAIGHT. Malic dehydrogenase activitv at 101 C under hydrostatic pressure. J. Bacteriol. 83:1341-1346. 1962.-No malic dehydrogenase activity was found to occur at 101 C at various hydrostatic pressures from 1 to 700 atm. However, activity was demonstrated with hydrostatic pressures above 700 atm, with optimal activity at 1,300 atm at the same temperature. Explanation of the data is based upon thermal denaturation of the enzyme, which involves a molecular volume increase of the enzyme. The molecular volume increase is counteracted by hydrostatic pressure. Pressures above 700 atm to 1,500 atm …

Interaction Between The Parameters Of Hydrostatic Pressure And Temperature On Aspartase Of Escherichia Coli, Roger D. Haight, Richard Y. Morita

Papers in Microbiology

HAIGHT, ROGER D. (University of Nebraska, Lincoln) AND RICHARD Y. MORITA. Interaction between the parameters of hydrostatic pressure and temperature on aspartase of Escherichia coli. J. Bacteriol. 83:112-120. 1962.-The data obtained from studies of an aspartase preparation and aspartase in cells of Escherichia coli indicate that there is an interaction between the parameters of hydrostatic pressure and temperature. Pressure was found to decrease aspartase activity at 45 C and lower in vitro and below 53 C in vivo, thereby indicating that when the enzymesubstrate complex is formed there is an increase in molecular volume which is counteracted by pressure. Above …

A Middle Miocene Rhinoceros Quarry In Morrill County, Nebraska (With Notes On Hip Disease In Diceratherium), Robert M. Stecher, C. Bertrand Schultz, Lloyd G. Tanner

Bulletin of the University of Nebraska State Museum (1924–2023)

Extensive deposits of fossil rhinoceros bones have been excavated from University of Nebraska State Museum collecting localities Mo-113, -114, -115, -116, and -118 some 8 1/2 to 9 1/2 miles north of Bridgeport, Morrill County, Nebraska. The fossils were associated with other faunal elements in the lower portion of the Marsland formation (middle Miocene) of the Hemingford group. The rhinoceros is considered to be Diceratherium niobrarensis Peterson, geologic variety. A pathologic right femur of D. niobrarensis provides evidence of hip disease in the medial Miocene rhinoceroses.

Early Records Of Some Mammals From Nebraska, J. Knox Jones Jr.

Bulletin of the University of Nebraska State Museum (1924–2023)

Ten species of Recent mammals that formerly occurred in Nebraska have been extirpated there by European man. Surprisingly few specimens of the species concerned are preserved in museum collections. Perusal of a representative segment of the historical literature pertaining to Nebraska has revealed records of occurrence of most of the extirpated species that provide a basis for estimating the former distribution of each in the State.

Evaluation Of Sires Available Through Planned Mating, L. Dale Van Vleck, C. R. Henderson, H. W. Carter

Department of Animal Science: Faculty Publications

There is some concern that methods of sire evaluation which utilize contemporary stablemate averages can be biased by differential genetic merit of the mates of these sires. A little reflection, however, indicates that even if the cows to which some sires are mated are more highly selected than the mates of other sires, this differential merit will not affect seriously the ranking of sires according to the evaluation of their progeny. Until the present, data have not been readily available with which to study the seriousness of this problem. The present study does not deal with the question generally, but …

Sire Evaluation From Five-Month Daughter Records, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

The chief advantages of sire evaluation based on five-month daughter records are: 1. Genetic progress is inversely proportional to the turnover rate in testing bulls so that if this interval is shortened by 10%, the rate of genetic progress will be increased by 11%. The turnover period can be shortened with the use of 5-month records from about 50 months to 45 months—a decrease of 10% in time. 2. Genetic progress is also related to how many top bulls are saved and how many poor ones are culled out of all those sampled. In other words, the more bulls tested …

Effect Of Levels Of Meat And Bone Scraps On Growth Rate And Feed Efficiency Of Growing-Finishing Swine, E. R. Peo, Jr., D. B. Hudman

Department of Animal Science: Faculty Publications

Many investigations have shown that soybean meal when properly supplemented can replace meat and bone scraps as a major source of protein in swine rations (Lepley et al., 1950; Terrill et al., 1954; Rohlf, 1954; Meade and Hanson, 1957; Meade et al., 1958; Becker et al., 1960). The importance of this finding is emphasized by the work of Bloss et al. (1953), Terrill et al. (1954), Meade and Teter (1957) and Becker and Jensen (1961) who reported a significant depression in growth rate and feed efficiency of swine fed rations containing relatively high levels …

Parameters For Milk Yield And For Percents Of Ash, Dry Matter, Fat And Protein In Sows, W. G. Pond, L. Dale Van Vleck, D. A. Hartman

Department of Animal Science: Faculty Publications

Milk was collected separately by machine from four to six glands on nine Yorkshire and Berkshire sows 2 or 3 days after farrowing and at weekly intervals throughout 6 weeks of lactation. Milk yield was measured following intramuscular injection of oxytocin, and the percent of ash, dry matter, fat and protein in the milk from each gland was determined. The average milk yield per gland, following a 1-hour period during which the pigs had been removed from the sow reached a peak of 74.6 gm. 3 weeks after farrowing. The ash content was 0.79% 2 or 3 days after farrowing, …

Studies On Parorchis Acanthus (Trematoda: Digenea) As A Biological Control For The Southern Oyster Drill, Thais Haemastoma, Nelson R. Cooley

United States Fish and Wildlife Service: Publications

Events in the attack on the southern oyster drill, Thais haemastoma, by miracidia of the digenetic trematode, Parorchis acanthus, are described.

Infection rates in wild drill populations of various Gulf Coast localities from Florida to Texas were low, but intensity of infection in individual drills was high and caused castration. Infection rates in laboratory experiments were high, but intensities were low.

Pathology of natural infections in drills is described. The infection lasts at least two years, possibly even for life.

Natural infection rates of juvenile herring gulls (Larus argentatus) , ring-billed gulls (L. delawarensis), and …

New Teacher Education Program, Howard W. Deems

Department of Agricultural Leadership, Education, and Communication: Faculty Publications

The University of Nebraska has a new training program for agricultural educators. It replaces the Department of Vocational Education established in 1922 for the purpose of training vocational agriculture and vocational homemaking teachers.

The Magnetic Pole In The Formulation Of Electricity And Magnetism, Robert Katz

Robert Katz Publications

The use of the magnetic pole in the development of the concepts of electricity and magnetism leads unambiguously to a relativistic formulation of the field vectors which is well within the grasp of the sophomore student. The development is wholly consistent with Maxwell's equations and leads to clear and understandable definitions of the field vectors both in vacuum and in the material medium, as well as to the relations defining the transformations of the field vectors.

Distributional Notes On Parasitic Mites, William F. Rapp Jr.

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Although much has been written on the systematics of mites little, to date, has been published regarding their distribution. Strandtman and Wharton (1958) have given distributional data on a large area basis i.e. United States, Mexico, etc., but have given only little specific distribution. Unfortunately much of our knowledge relative to mite distribution is limited to a knowledge of type localities. In the case of parasitic mites one cannot assume that the distribution of the parasite is the same as the host. Unfortunately at this time, we do not know what factors limit the distribution of parasitic mites.

Municipal Fair Employment Practices In Nebraska, Denis G. Stack

Nebraska Law Review

The city of Omaha recently enacted an ordinance regulating fair employment practices (FEP). By the ordinance, employers, employment agencies, and labor organizations are prohibited from discriminating against employees, job applicants, or members on the basis of race, color, creed or national origin. The ordinance was the center of much controversy: the assistant city attorney stated the city lacked the power to enact the ordinance, and the city's leading newspaper opposed the law.
