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.

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.

Distribution Of Army Cutworm Larvae In Wheat And Barley Fields, K. P. Pruess

Department of Entomology: Faculty Publications

Populations of the army cutworm, Chorizagrotis auxiliaris (Grote), tended to be higher in winter barley than winter wheat planted side by side in the same field. Highest populations occurred in barley within 30 feet of the adjoining wheat. Distribution of larvae in linear 1-foot samples agreed closely with the Poisson. Practical application of these results are discussed.

Effects Of Moisture On The Clover Root Borer And Red Clover Yields, K. P. Pruess, C. R. Weaver

Department of Entomology: Faculty Publications

Rainfall and populations of the clover root borer, Hylastinus obscurus (Marsham), were artificially controlled in pots of red clover grown under shelters in the field. Populations of clover root borer were higher under dry conditions. Although yield losses were high in borer-infested pots, yield reductions were no greater under dry than under wet conditions.

An Iron Fulgurite From Nebraska, C. M. Riley

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

From the time of the ancients man has been impressed with the force of lightning and its effect on the rocks at the surface of the earth. It was Saussure in 1786 who first wrote a scientific account of a true fulgurite, and a wealth of literature has been written about the subject since this time. Many unusual fulgurites have been described, some of which may not truly be the result of lightning. The iron fulgurite is a strange conical object about 3 inches high composed mainly of tiny spheres and filaments of metallic iron intermixed with a small amount …

Harry Scott Smith, Biological Control: Riverside (1883-1957): University Of California: In Memoriam, 1959, A. M. Boyce, H. Compere, R. Van Den Bosch

Department of Entomology: Faculty Publications

Harry Smith was born at Aurora, Nebraska, November 29, 1883. He was brought up as a farm boy and experienced all the rigors of life on a prairie farm in the latter part of the nineteenth century. The hours of work in the fields, from dawn to dusk, made an indelible impression. Admittedly, he escaped from “haying” and “tending hogs” by enrolling in the State University at Lincoln, where he worked his way by waiting on tables at fifteen cents an hour. There he was granted his A.B. degree in 1907 and his M.S. degree in 1908. Insects became his …

Effect Of Host Condition On The Clover Root Borer, K. P. Pruess

Department of Entomology: Faculty Publications

Oviposition by the clover root borer, Hylastinus obscurus (Marsham), is completed earlier in weakened than in vigorous plants, but development is more rapid in vigorous or lightly infested roots. High populations occurring early in the season result in plant mortality with subsequently slowed borer development.

Tests With Poison Baits Against Cockroaches, C. S. Lofgren, G. S. Burden

Entomology Papers from Other Sources

Poison baits consisting of some food material with a toxicant such as phosphorus or boric acid have been used for many years for controlling the cockroaches (Mallis 1954, pp. 181-5). Recently Keller et al. (1956) reported that a bait consisting of cornmeal (73 percent), Coca-Cola syrup (25 percent), and Dipterex (2 percent) controlled Periplaneta spp. in homes for 30-60 days.

Control Of Hog Lice And Mange, Robert Roselle

Department of Entomology: Faculty Publications

The hog louse (Haematopinus suis) is the largest species of louse found on domestic animals. It may attain a length of one-quarter of an inch. The body is oval, and the legs terminate in large, dark claws well adapted to cling to hairs. Hog lice are bluish-gray in color. They are found only on hG>gs except in very unusual cases. The eggs or "nits" are glued to the hairs and hatch in 12 to 20 days. Young lice mature in 10 to 12 days. The average life cycle is about 35 days. Lice suck blood from the host, and …

Further Tests Of Band Placement Of Insecticides For Clover Root Borer Control, C. R. Weaver, K. P. Pruess, J. L. Parsons

Department of Entomology: Faculty Publications

Weaver & Haynes (1955) described a method of placement of insecticides in bands under red clover seed that achieved control of the clover root borer, Hylastinus obscurus (Marsh.). Band placement was as effective at 0.75 pound of toxicant per acre as broadcast treatments at 1 pound or more as reported by Gyrisco et al. (1954) and App & Everly (1950). Since the 1951–53 tests were carried out in one location on small plots and applied by a farm crew experienced in experimental procedures, it was desired to test the band placement method more extensively. Tests in 1954–56 were conducted at …

Case Of Collecting Tick Amblyomma Lepidum Dönitz, 1909, In Azerbaijan, M. V. Pospelova-Shtrom, N. S. Abusalimov

United States Naval Medical Research Unit 3: Publications

First paragraph:

On 18 May 1954, (a specimen of) Burhinus oedicnemus (L.) was killed in the Lenkoransky region of Azerbaijan S.S.R.; on its head a male Amblyomma lepidum Dönitz, 1909, was found. Morphological characters of this tick, size and shape of body, characteristic light and dark ornamentation of dorsal shield, punctation, shape, and two colors of festoons, size and shape of cervical and lateral grooves, hypostome, peritreme, projection on coxae, and spherical orbited eyes correspond to those in the description of A. lepidum, given in Robinson monograph. Only on four anterior festoons a small light spot is found (in …

Medial Pleistocene Fossil Vertebrate Localities In Nebraska, C. Bertrand Schultz, Lloyd G. Tanner

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

The accurate geologic dating of Pleistocene vertebrate localities which occur outside the glaciated regions has always been difficult. Several new fossil localities in Nebraska now provide data for a better understanding of the paleoecology and faunal evidence of the medial Pleistocene of the Great Plains region.

A fossil quarry, containing the remains of both vertebrates and invertebrates, has been discovered in south-central Nebraska (11/2 miles south and west of Angus in Nuckolls County). The fossils are preserved in Sappa silts in a lime concentration zone (C horizon) of a Yarmouth paleosol. The calcium carbonate appears to have been responsible for …

Arretotherium Fricki, A New Miocene Anthracothere From Nebraska, J. R. Macdonald, C. Bertrand Schultz

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

A new species of middle Miocene (early Hemingfordian) anthraco-there, Arretotherium fricki Macdonald and Schultz is described based on a cranium from the upper Marsland deposits of Nebraska. The holotype suggests that this genus was derived from the Oligocene genus Elomeryx Marsh.

Classification Of Oligocene Sediments In Nebraska: A Guide For The Stratigraphic Collecting Of Fossil Mammals, C. Bertrand Schultz, Thompson M. Stout

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

The Chadron and Brule formations constitute the White River Group in Nebraska and adjacent states. The Brule is divided into the Orella and Whitney members. The latter members are referred to the Medial and Late Oligocene (equivalents of the European Stampian and Aquitanian), while-the Chadron is equated with the Early Oligocene (Sannoisian). Each unit in Nebraska is subdivided into three parts (Lower, Middle, and Upper; or A, B, and C for the Chadron and Whitney, and A-B, C, and D for the Orella). Key beds such as fossil soils (paleosols), Purplish White beds, and volcanic ash layers, when considered with …

Paleosols Of The Oligocene Of Nebraska, C. Bertrand Schultz, Lloyd G. Tanner, Cyril Harvey

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

Prominent paleosol ("buried" or "fossil" soil) complexes occur at the top of the middle Orella, upper Orella, lower Whitney, and upper Whitney in the Brule formation of Nebraska; and at the top of the "Lower Oreodon," "Middle Oreodon," "Upper Oreodon," and "Leptauchenia" beds in the Brule deposits of South Dakota. These paleosols have regional distribution and appear to be of value in stratigraphic correlations. Major faunal breaks seem to coincide with important buried soil zones, thus indicating that certain paleosols actually represent unconformities. Some of the soils were developed on old land surfaces where deposition was practically at a standstill …

50 Years Of Research At The North Platte Experiment Station, W. W. Burr, J. C. Adams

Nebraska Agricultural Experiment Station: Historical Circulars

The North Platte Experiment was established fifty years ago. So many changes have occurred since then that few people remember why research in dry land agriculture was started in Nebraska and other Great Plains states. In order to get a proper perspective, it may be well to consider some early history.

This is the second of a series of papers on the Orthoptera of Nebraska. It is a continuation of the revision of an unpublished thesis on this subject by the author in 1934.

A Report On Drosophila Collections In Nebraska, David D. Williams, Dwight D. Miller

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

Until rather recently little has been known of the Drosophila species of Nebraska. Sturtevant (1921) lists Nebraska as one of seven states from which no Drosophila had been reported. Patterson and Wagner (1943) show that collections of Drosophila pseudoobscura had been made in the vicinities of Scottsbluff and Kearney, but no other Drosophila species are reported from Nebraska in their publication.

Insect Types In The Collections Of The University Of Nebraska State Museum, Martin H. Muma

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

In 1948 the insect collections at the University of Nebraska State Museum were placed in the care of the author. Prior to that date curatorial duties were assumed or assigned to full time teaching or research staff members. As would be expected under the latter circumstances, the organization of study material and types was neglected in many families and genera. Since 1948 type material, because of its intrinsic value, has received considerable attention. All primary and representative secondary types have been assembled in three museum cases and one slide cabinet for curatorial and study convenience.

A Graphic Résumé Of The Pleistocene Of Nebraska (With Notes On The Fossil Mammalian Remains), C. Bertrand Schultz, Gilbert C. Lueninghoener, W. D. Frankforter

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

I T SEEMS desirable at this time to present a graphic resume of the Nebraska Pleistocene, together with a summary of the stratigraphic sequences of the fossil vertebrates. This report is based on data taken from various publications' in addition to information gathered by the present writers during the past fifteen or more field seasons. Intensive work has been done in the past five years in connection with recovery of paleontological material in the areas where government dams are under construction (Schultz, Lueninghoener, and Frankforter, 1948; Schultz and Frankforter, 1948; Holder and Wike, 1949). The information in the present paper …

An Annotated List Of The Orthoptera Of Nebraska Part I The Blattidae, Mantidae And Phasmidae, Harold A. Hauke

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

This paper is the first of a series on the Orthoptera of Nebraska. In 1932, while a graduate student at the University of Nebraska, the author began a taxonomic study of the Orthoptera, the result of which was an unpublished List of the Othoptera of Nebraska. The list has been studied and revised.

Effects Of Weather, Sanitation And Chlorinated Chemical Residues On House And Stable Fly Populations On Nebraska Farms, Martin H. Muma, Ephriam Hixson

Department of Entomology: Faculty Publications

Since L. O. Howard's (1906) early report on house flies many entomologists have conducted research on these insects. Their reports range from notes on the hibernation of house flies, Musca domestica L., to lengthy papers on the biology and control of house flies and stable flies, Stomoxys calcitrans (L.). Early control studies stressed the importance of sanitatioll, screening and the use of mist type contact insecticides. These standard control measures have not, however, received much attention in the United States since Wiesmann (1943) reported on the pro-longed effectiveness of a new insecticide "Gesarol." Scores of other workers have also published …

Preliminary Geomorphological Studies Of The Lime Creek Area & Preliminary Report On The Lime Creek Sites: New Evidence Of Early Man In Southwestern Nebraska, C. Bertrand Schultz, Gilbert C. Lueninghuener, W. D. Frankforter

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

PALEONTOLOGICAL and archaeological discoveries were made near Cambridge, Nebraska, by the University of Nebraska State Museum field party in the spring of 1947 (Schultz and Frankforter, 1948, pp. 279-280) . Fossils and artifacts were found in situ at the base of a fifty-foot terrace on Lime Creek (University of Nebraska State Museum Localities Ft-41 and Ft-42) and on Medicine Creek just below the mouth of Lime Creek (Ft-50). Lime Creek is located (Fig. 1) in southwestern Nebraska in the southeastern part of Frontier County. It is a tributary of Medicine Creek which in turn is a tributary to the Republican …
