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 …

Vertebrate Pest Control, Walter E. Howard

Vertebrate Pest Conference Proceedings: 1st (1962)

It is a pleasure and privilege for me to welcome all of you to this conference. And it is a conference, not a convention. No motions or resolutions will be entertained, as this conference is made up of representatives of many governmental agencies and countries; hence, not a place for resolutions. We are here to get acquainted with each other and to listen to experts from North America and Korea tell us about the best methods of controlling troublesome and pestiferous birds, mammals and snakes, and to discuss related problems concerning diseases and pesticides. Since the program is crowded, each …

The Pest Animal Problem: Keynote Speech, W. C. Jacobsen

Vertebrate Pest Conference Proceedings: 1st (1962)

There is an inscription across the top of the impressive facade of the National Archives Temple in Washington, D. 0., which reads: "What is Past is Prologue." So be it. Perhaps it applies to us here- At least the inscription furnishes a basis for me to indulge in a few com¬ments of historical significance as we undertake consideration of vertebrate pest control in its many phases. The earlier documents available to us reveal that with every expansion or westward advance into newer areas of agricultural production or livestock enterprises there also arose a variety of pest animal problems. However, it …

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 …

Ground Squirrel Control In California, Richard H. Dana

Vertebrate Pest Conference Proceedings: 1st (1962)

The control of ground squirrels in California is important in two ways. First, it is necessary to prevent destruction of agricultural crops. Second, it is important from a health standpoint where rodent-borne diseases have been demonstrated to be present. Ground squirrel control in this State is the responsibility of the county agricultural commissioners, the State Department of Agriculture and on Federal lands the Bureau of Sport Fisheries and Wildlife. Most control measures are concerned with but two of the nine species of ground squirrels found in California. These include four subspecies: Beechey ground squirrel (Citellus beecheyi beecheyi), Douglas ground squirrel …

Banquet Address: People, Pests And Some Plans, Daniel G. Aldrich Jr.

Vertebrate Pest Conference Proceedings: 1st (1962)

We can probably say that the California way of farming has made California fanners the most over-run hosts to vertebrate pests in the agricultural world. We can certainly say, too, that new pests—and here I don't mean people--are on their way. I'm told that the starlings are just exploring here now. The relatives are coming later. We'll see, and hear, a lot more of them. Our problem is: How do we keep from being such good hosts to our small vertebrate guests? I have been told by experts that right now the vertebrate pest control man is woefully underequipped for …

Control Of Pocket Gophers, Maynard W. Cummings

Vertebrate Pest Conference Proceedings: 1st (1962)

Pocket gophers occur only in North and Central America but within this vast area few other native rodent groups are more widely distributed (Anthony, 1928). None are more adaptable, either to natural extremes of habitat or to changed conditions brought about by agricultural development and other man-made environmental modifications. They occupy coastal areas, inland plains and valleys, desert and alpine meadow, from sea level to above timber line in a multitude of vegetation and soil types. This practically universal distribution has, of course, led to the recognition by naturalists of many species and subspecies. California alone contains at least 75 …

Control Methods For Snakes, Elbert M. Brock, Walter E. Howard

Vertebrate Pest Conference Proceedings: 1st (1962)

Of the various types of wildlife that home owners find undesirable, snakes are probably the leading offenders. Because of much false teaching, many persons have a great dread of even non-venomous snakes; hence control often is practiced when not needed. Nevertheless, very few people are willing to accept the presence of snakes in their gardens or their yards, especially if there is a concern for children playing in the area. For this reason snake control is often desirable about homes and suburban housing areas. Other situations where controls might be justified are recreation areas, farms, bird sanctuaries, duck nesting marshes, …

Public Health Service Drinking Water Standards

United States Public Health Resources

The Standards published herein have been promulgated as Public Health Regulations in the Federal Register. As such they became effective April 5, 1962, as the Standards to which drinking water and water supply systems used by carriers and others subject to Federal quarantine regulations must conform. The Division of Environmental Engineering and Food Protection is responsible for the application of these Standards to all carrier water supplies. These Standards supersede the Public Health Service Drinking Water Standards- 1946, as amended in 1956. The new Standards were developed with the assistance of an Advisory Committee appointed by the Public Health Service …

Purification And Sanitary Control Of Water (Potable And Waste), Paul W. Kabler

United States Public Health Resources

Although most of the streams draining inhabited regions are contaminated with human or animal feces, water-borne disease today in the United States is relatively uncommon. Pathogenic enteric microorganisms probably do not multiply in raw water sources under normal conditions. They usually disappear in a relatively short time, with the rates depending on variations in environmental conditions. Urban water supplies have played a diminishing role in the transmission of intestinal disease because of improvements in the detection and enumeration of pollution indicators, water and sewage treatment processes, and t h e sanitary control of water systems.

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.

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 …

The Cooperative Control Of Wildlife Damage, Clifford C. Presnall

Other Publications in Wildlife Management

To avoid careless destruction has been the constant aim of the Bureau of Sport Fisheries and Wildlife, and this is the basis of our strict regulations, inflexible accountability for control poisons and control devices, and emphasis on professional supervision at all levels. Our goal is to manage wildlife damage at a level tolerable to those sustaining it and without jeopardy to populations of animals regarded as desirable. It is our job to find ways for people and wildlife to live harmoniously together in this complex age.

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.

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 …

The Effects Of Irradiating Dormant Maize Seeds With Xrays And Thermal Neutrons, Rosalind Morris, E. F. Frolik

Nebraska Agricultural Experiment Station: Historical Research Bulletins

In 1951 a research program was started at the University of Nebraska to compare the developmental effects of thermal neutrons and X rays on different crop seeds. Three crops, barley, tomato and maize, were chosen for additional information involving induced chromosomal aberrations and seedling mutations. The maize investigations are presented in this bulletin, along with a comparison among the three crops with respect to irradiation effects.

Fm 55-8, Transportation Intelligence, 1961, Robert Bolin , Depositor

United States Department of Defense Military Intelligence

In 1961, American military intelligence was decentralized. The Army was responsible for all intelligence concerning foreign armed forces. Within the Army, the technical services – Transportation Corps, Signal Corps, Ordnance Corps, etc. – were responsible for intelligence concerning analogous organization in foreign organizations. The Transportation Corps was responsible for intelligence concerning foreign transportation equipment and services. Since there was no centralized American military intelligence organization, the Transportation Corps was tasked with supplying intelligence concerning foreign road and rail networks and waterways as well as ports and landing beaches and airfields.

This manual defines transportation intelligence and prescribes Army doctrine concerning …

The Living Network In Prairie Soils, J. E. Weaver

Department of Agronomy and Horticulture: Faculty Publications

This study treats of our midcontinental soils and of the wonderful network of roots within them of a vegetation which has clothed them for untold centuries. This vegetation has almost vanished so great has been the toll of the tractor-drawn plow, over- grazing and trampling, injudicious use of poisonous sprays, building of highways, and other causes. Virgin prairie and undisturbed soil occur in quantity only in areas where limestone underlies a shallow soil and prevents plowing or in sand so unstable that destroying the vegetation with its binding roots is almost synonymous with losing the soil. The many thousands of …

A Histological Study Of The Postnatal Development Of The Bovine Testis, R. G. Fossland, A. B. Schultze

Nebraska Agricultural Experiment Station: Historical Research Bulletins

A limited number of detailed studies on the development of the bovine testis from birth to sexual maturity have been reported. Further study of bovine testis development appears desirable to furnish additional observations and to note variations that may occur during the developmental process. Information on the process of spermatogenesis should furnish a basis for experimental work designed to promote increased spermatogenic activity in the postpubertal testis as well as for work directed toward promoting complete spermatogenesis at an earlier than usual age. This report is a study of the histological picture of the testes from 56 bulls varying from …

Oviposition Response Of The Army Cutworm, Chorizagrotis Auxiliaris, To Different Media, K. P. Pruess

Department of Entomology: Faculty Publications

Moths of the army cutworm, Chorizagrotis auxiliaris (Grote), (Lepidoptera: Noctuidae) responded ovipositionally to differences in soil color, texture, and depth. Number of eggs laid increased with amount of light reflected. A combination of loose surface over a solid substrate was required. A light-colored sand fulfilled all requirements and was preferred over soil. Soil was acceptable when a loose surface of correct depth was provided. Solid surfaces were refused.

Correspondence About "Evolutionary Relationships Among The North American Mallards", Allan R. Phillips, Paul A. Johnsgard

Papers in Ornithology

The confusing leading article of the 1961 Auk calls for comment. Despite his title, "Evolutionary Relationships among the North American Mallards," the author discusses primarily geographic distributions, population sizes, egg-white proteins( !), and certain behavioral patterns. Maps are based on ". . . the literature, personal communications, and the major United States collections," " . and from additional sight and specimen records available to me"; yet only two museums other than Cornell University are mentioned in the acknowledgments. These maps show many records of platyrhynchos far to the south; sometimes (Figure 1) the reader must search hard for any hint …
