Hatching Of Sod Webworm Eggs In Relation To Low And High Temperatures, Ellis L. Matheny, E. A. Heinrichs Jan 1971

Hatching Of Sod Webworm Eggs In Relation To Low And High Temperatures, Ellis L. Matheny, E. A. Heinrichs

Department of Entomology: Faculty Publications

Eggs of 12 species of sod webworm were exposed for various periods to temperatures of 0, 10, and 45°C. Hatchability was compared with control eggs kept at 25°C. Short exposures to any temperature did not significantly affect percent hatch. Prolonged exposure resulted in a significant decrease in hatchability for several species at 0° and for all species at 45°C. There was a significant difference in hatchability between the 3 generations of Crambus teterrellus (Zincken) and of Pediasia trisecta (Walker) at extreme temperatures. Populations of Agriphila ruricolella (Zeller), collected at 2 elevations, differed significantly in hatching percentage and developmental rate.


Antigenic Relationships In Seven Strains Of Tetrahymena, W.E. Engelhard, B.W. Mccashland Jan 1971

Antigenic Relationships In Seven Strains Of Tetrahymena, W.E. Engelhard, B.W. Mccashland

Papers in Microbiology

Tetrahymena, along with other genera of the family Frontoniidae, have been the subject of many scientific investigations concerning problems in protozoan physiology. Unfortunately in many instances, difficulty arises when attempting to identify properly the form that was used in the particular study. Until rather recently, relatively little had been accomplished by way of a comprehensive study of the interrelated genera, and of these very few have dealt with taxonomic problems serologically.


Observations On Sound Production In The Anatidae, Paul A. Johnsgard Jan 1971

Observations On Sound Production In The Anatidae, Paul A. Johnsgard

Paul Johnsgard Collection

It has been known for a long time that, among non-passerine birds, the Anatidae are remarkable for the diversity of specializations in the trachea and syrinx, associated with sound production. It has also been recognised that these variations have taxonomic significance (Heinroth 1911; Johnsgard 1961), but virtually no attempts have been made to correlate the complex tracheal structures with the sounds produced. Yet the group offers many fascinating problems such as the adaptive significance of the looping of the trachea, either outside the body cavity as in the Magpie Goose Anseranas semipalmata, or inside the sternum as in the …


Morphology Of The Spores Of Myxosoma Cerebralis (Hofer, 1903) And M. Cartilaginis (Hoffman, Putz, And Dunbar, 1965)*, Glenn L. Hoffman, Jiří Lom Jan 1971

Morphology Of The Spores Of Myxosoma Cerebralis (Hofer, 1903) And M. Cartilaginis (Hoffman, Putz, And Dunbar, 1965)*, Glenn L. Hoffman, Jiří Lom

United States Fish and Wildlife Service: Publications

The spore of Myxosoma cerebralis is redescribed and compared with that of a close relative, M. cartilaginis. M. cerebralis is smaller, with greater variability in size and shape. It possesses a mucous envelope whereas M. cartilaginis does not. The surface architecture of M. cerebralis, as seen with the scanning electron microscope, differs in possessing a conspicuous circumsutural groove, prominent polar filament pores, and a mucous envelope.

The Fishes Of The Nemaha Basin, Nebraska, Larry Witt Nov 1970

The Fishes Of The Nemaha Basin, Nebraska, Larry Witt

Nebraska Game and Parks Commission: Staff Research Publications

The possible effects of proposed watershed management practices on fish resources of the Nemaha Basin were poorly understood; thus, a study was undertaken to ascertain the species of fish present and their relative abundance and distribution within the basin. Thirty-five species were collected, 34 of them from the Big Nemaha River system and 28 from the Little Nemaha River system. These data may be used as a basis for future studies of fish population changes in the Nemaha Basin and possibly as a basis for studies in other watersheds.


Studies On The Helminth Fauna Of Alaska. Xlix. The Occurrence Of Diphyllobothrium Latum (Linnaeus, 1758) (Cestoda: Diphyllobothriidae) In Alaska, With Notes On Other Species, Robert L. Rausch, D. K. Hilliard Nov 1970

Studies On The Helminth Fauna Of Alaska. Xlix. The Occurrence Of Diphyllobothrium Latum (Linnaeus, 1758) (Cestoda: Diphyllobothriidae) In Alaska, With Notes On Other Species, Robert L. Rausch, D. K. Hilliard

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Cestodes representing six species of the genus Diphyllobothrium Cobbold, 1858, were collected from naturally infected terrestrial mammals in Alaska during the period 1949-1970. Additional specimens were reared in experimentally infected animals. Of the species identified, viz., D. latum (Linnaeus, 1758), D. dendriticum (Nitzsch, 1824), D. lanceolatum (Krabbe, 1865), D. ursi Rausch, 1954, D. dalliae Rausch, 1956, and D. alascense Rausch and Williamson, 1958, all but D. alascense were obtained from man after treatment with quinacrine. D. latum occurred most commonly in humans; D. ursi is reported for the first time from this host, and D. lanceolatum in humans was represented …


Raman Scattering From Localized Vibrational Modes In Gap, D. T. Hon, W. L. Faust, W. G. Spitzer, P. F. Williams Oct 1970

Raman Scattering From Localized Vibrational Modes In Gap, D. T. Hon, W. L. Faust, W. G. Spitzer, P. F. Williams

P. F. (Paul Frazer) Williams Publications

High-frequency localized vibrational modes of impurities in a III-V compound have been observed by Raman scattering. Three lines from the GaP samples closely correspond to some loccal modes previously reported in infrared studies, and depolarization measurements tend to confirm their proposed assignments. We describe several attractive features of this method for the study of semiconductor impurities.

Nonbiolog1cal Alteration Of 3-Chloro P-Toluidine Hydrochloride (Drc-1339) In An Aqueous Solution, T. R. Darden, Robert G. Schwab Sep 1970

Nonbiolog1cal Alteration Of 3-Chloro P-Toluidine Hydrochloride (Drc-1339) In An Aqueous Solution, T. R. Darden, Robert G. Schwab

Bird Control Seminars Proceedings

The effectiveness of 3-chloro p-toluidine (DRC-1339) as an avicide, particular¬ly on the European starling, has been adequately demonstrated (DeCino, Cunningham, and Schafer, 1966; Schwab, 1965, 1966, and 1967). Methods of applying the com¬pound which have proved useful range from the standard baiting technique (Besser, Royall, and DeGrazio, 1967; Royall, DeCino, and Besser, 1967; West, 1968) to pos¬sible aerial application of the compound to roosting sites (Schwab, 1967). These methods, particularly the latter, inherently lead to widespread environmental exposure. As the chemical name implies, DRC-1339 is a chlorinated hydrocarbon. It thereby carries the stigma, whether justifiable or not, of environmental persistence …


Sonic Systems For Controlling Bird Depredations, William D. Fitzwater Sep 1970

Sonic Systems For Controlling Bird Depredations, William D. Fitzwater

Bird Control Seminars Proceedings

The sounds used in controlling bird depredations can be classified into three types:

(1) AUDIBLE DISTURBING NOISES: From clapping of hands by primitive peoples to the modern exploding shotgun shells, loud noises have long been used to frighten birds from man's crops. They are still a valuable supplement to other methods or when needed for short, discontinuous periods.

(2) ULTRASONICS: Sounds over 20,000 cps are apparently beyond the limit of birds as well as humans. There is no effective use of ultrasonics in bird control as yet.

(3) BIOSONICS: While song is a more noticeable facet of bird communication, the …


The Dickcissel: A Problem In Ripening Grains In Latin America, Jerome F. Besser, John W. De Grazio, Kenneth H. Larsen Sep 1970

The Dickcissel: A Problem In Ripening Grains In Latin America, Jerome F. Besser, John W. De Grazio, Kenneth H. Larsen

Bird Control Seminars Proceedings

Bird damage to crops in Latin America--from Mexico to Venezuela and Colom¬bia-is chiefly caused by fringillids, icterids, and psittids (De Grazio and Besser, 1970). Damage to grains such as rice and grain sorghum by various fringillids-sometimes re¬ferred to as "chisguas" by local landowners-is especially troublesome. The fringillid most often implicated in major problems is the dickcissel (Spiza americana).

Dickcissels are not known to cause serious damage problems within their breed¬ing range, which is chiefly the prairies and hay meadows of the central United States. In August, small postbreeding flocks congregate, and by September and October these coalesce into much larger …


The Chemical Senses Of Birds, Morley R. Kare Sep 1970

The Chemical Senses Of Birds, Morley R. Kare

Bird Control Seminars Proceedings

Birds are not concerned with the odors of their immediate environment. To a chicken, a starling or a cowbird, the odors of its environment are of little or no con-sequence. I am not saying that birds do not have the apparatus for olfaction, nor am I saying that no bird can smell. The kiwi of New Zealand is almost totally blind and does sniff. They do have "nostrils" on the tip of the bill. However, they are an unusual exception. If we place highly odoriferous material under one of two food choices and present them to domestic chickens or starlings, …


Bird Hazards To Aircraft, Victor E. F. Solmon Sep 1970

Bird Hazards To Aircraft, Victor E. F. Solmon

Bird Control Seminars Proceedings

When I spoke to the third Bird Control Seminar in 1966 on "Ecological Control of Bird Hazards to Aircraft", I reviewed what we had accomplished up to that time. I spoke about the extent of the problem, the bird species involved and the methods we used to make the airports less attractive to birds that created hazards to aircraft.

I wish to discuss today our accomplishments since 1966. I have presented a number of papers on the topic including one with Dr. W. W. H. Gunn, in 1967 at a meeting in the United Kingdom, and others in the United …


Mp25 The Problem Of Freight Car Supply, John Richard Felton Aug 1970

Mp25 The Problem Of Freight Car Supply, John Richard Felton

Department of Agricultural Economics: Faculty Publications

As early as 1907 the Interstate Commerce Commission held extensive hearings on freight car shortages. At frequent intervals ever since, Congress and the commission have addressed themselves to the problem of freight car supply with considerable vigor but meager results. Allegations of an inadequate supply of freight cars have been widespread in recent years. The decline in the number of freight cars is easy to document: between 1959 and 1968, the number of cars used in grain transport (boxcars and covered hopper cars) declined by 26%. If, however, consideration is given to changes in car capacity and car miles …

A Study Of The Architectural Space Necessary To Perform The Theatre Of Antonin Artaud, Larry L. Peterson Aug 1970

A Study Of The Architectural Space Necessary To Perform The Theatre Of Antonin Artaud, Larry L. Peterson

Masters in Architecture Program: Theses

Preface excerpt

The theatre of Artaud was being attempted by a few companies, notably, the Royal Shakespeare Company with Peter Brook doing "Marat/Sade;" and the Living Theatre with Judith and Julian Beck performing "The Brig."

I found the style of both performances exciting, and as a student of architectural design, I found great challenge in attempting a theatre space study which would allow the environmental qualities of the space itself to become another tool of the mise en scene.

My point of view, which developed during this study, was that the theatre should demand the entire company's complete involvement …

Studies On The Helminth Fauna Of Alaska. Xlv. Schistotaenia Srivastavai N. Sp. (Cestoda: Amabiliidae) From The Red-Necked Grebe, Podiceps Grisegena (Boddaert), Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The genus Schistotaenia Cohn, 1900, at present includes six species, all parasites of grebes (Podicipediformes). Among helminths found in a red-necked grebe, Podiceps grisegena (Boddaert), on October 18, 1966, at Anchorage, Alaska, were cestodes representing two species of Schistotaenia, of which one is described here as new. The host was an adult bird which evidently had been injured during migration.

This cestode is named in honor of Dr. H. D. Srivastava, in recognition of his significant contributions to helminthological research.

Field Manual Fm 55-8, Transportation Intelligence, 12 March 1970, Robert Bolin , Depositor

United States Department of Defense Military Intelligence

Obviously, reliable information about potential enemy transportation equipment, facilities, systems, capabilities is vital, since our forces may need to prevent an enemy from using them and we may need to use them. Transportation or mobility intelligence is such reliable information. This is a very thorough document describing the collection, production, and dissemination of transportation intelligence. The emphasis of this manual is collection of relevant information in the field.

The manual describes organizations and personnel in the army responsible for collecting transportation related information. It identifies the national-level military intelligence production agencies as:

Opening Remarks - Fourth Vertebrate Pest Conference, Richard H. Dana

Vertebrate Pest Conference Proceedings: 4th (1970)

I am pleased to welcome you to the Fourth Vertebrate Pest Conference. This is our second Sacramento meeting. The first was in 1962 - eight years ago. It was an historic occasion. It was the first conference devoted exclusively to vertebrate pests. This conference is sponsored by the California Vertebrate Pest Committee comprised of representatives from the California Department of Agriculture, the University of California at Davis, Department of Animal Physiology and the Agricultural Extension Service; the U. S. Bureau of Sport Fisheries and Wildlife, Division of Wildlife Services and of Wildlife Research, the California Departments of Public Health, Fish …


Current Status Of Plague And Plague Control In The United States, Jack D. Poland, Allan M. Barnes Mar 1970

Current Status Of Plague And Plague Control In The United States, Jack D. Poland, Allan M. Barnes

Vertebrate Pest Conference Proceedings: 4th (1970)

During the first quarter of the 20th century massive rat-borne plague epidemics occurred in port cities of the United States in conjunction with the last world-wide pandemic which originated in China in 1893. By 1950, plague was found to be firmly established in wild rodent populations in states west of the 100th meridian. Presumably because of improved sanitation coupled with retreat of the world-wide pandemic there have been no human cases in this country associated with urban rats since 1924. However, sporadic cases, fewer than 10 per year, are reported as due to contact with wild rodents, lagomorphs, rural rats, …


Importance Of Wildlife Rabies Control, Richard L. Parker Mar 1970

Importance Of Wildlife Rabies Control, Richard L. Parker

Vertebrate Pest Conference Proceedings: 4th (1970)

ABSTRACT: Rabies in animals has been known in North America for over two centuries, and whether the disease was initially present in wild species or was introduced by dogs, it has been known in skunks for almost a century and a half. Today more rabies cases in wild animals are reported than in domestic animals, and a considerable proportion of both human and domestic animal exposures to the disease are the result of wild-animal contact. The most useful techniques for controlling wild animal rabies today are methods that reduce contact between infected individuals and susceptible individuals; these involve the manipulation …


Chemosterilants As An Approach To Rodent Control, Rex E. Marsh, Walter E. Howard Mar 1970

Chemosterilants As An Approach To Rodent Control, Rex E. Marsh, Walter E. Howard

Vertebrate Pest Conference Proceedings: 4th (1970)

Capitalizing on research directed toward oral contraceptives for humans, a wide variety of compounds are now under study for their practical value in inhibiting rodent reproduction to suppress detrimental populations. This paper discusses the specifications of ideal rodent chemosterilants and the advantages of chemosterilants over other methods of control, and compares the potential values of chemosterilants acting on females, males, and both sexes. Specific situations are detailed where chemosterilants will be most valuable in rodent control, together with proposed methods of application. Chemosterilants are not expected to become a panacea for control, but since they are based on sound biological …


Olfaction In Rodent Control, Walter E. Howard, Rex E. Marsh Mar 1970

Olfaction In Rodent Control, Walter E. Howard, Rex E. Marsh

Vertebrate Pest Conference Proceedings: 4th (1970)

A brief survey is presented of current knowledge on olfaction in rodents and the various roles that odors may play in modifying rodent behavior. Some species at least utilize olfactory cues: to locate food items; to recognize their mother and mates; to mark territory; as an involuntary population density regulator; possibly to recognize predators; as a warning cue against a repellent or toxic substance (poison-bait shyness); and probably, for many other behavioral purposes. The value of using artificial odors in rodent baits to increase bait acceptance is not yet well documented. The addition of attractive natural odors may increase detection …


Studies In Microencapsulation Of Rodenticides, P. B. Cornwell Mar 1970

Studies In Microencapsulation Of Rodenticides, P. B. Cornwell

Vertebrate Pest Conference Proceedings: 4th (1970)

Warfarin, zinc phosphide, norbormide and alphachloralose have been microencapsulated by the technique of coacervation and fed to laboratory rats (R. norvegicus) and mice (M. musculus). Results are given of experiments in which the concentration of rodenticide, wall material and phase ratio have been varied separately and in combination. Experiments are also reported in which normal and encapsulated rodenticide has been fed together in the same test diet.
