Agricultural Scene, Charles P. Stone

Bird Control Seminars Proceedings

It has been suggested that our approach to agricultural bird problems is perhaps wrong, and I feel it would be valuable to ask several individuals to give their ideas as to where their programs are heading right now. I would first like to ask Jerry Besser, the Chief of the Bird Section of the Denver Wildlife Center, to give just a brief statement as to where they are now. BESSER: Most of our efforts are being channelled into the agricul- tural area on a broad scale. Many of the problems are national ones. We can put our finger on the …

Bird Damage To Tart Cherries In Michigan, 1972, Charles P. Stone

Bird Control Seminars Proceedings

Bird damage to commercial fruits has long been a problem in many coun- tries, but the true magnitude of the damage incurred is difficult to determine objectively. Often the opinions of fruit growers provide the only measure of importance. In 1972, the U.S. Fish and Wildlife Service, the Michigan Department of Agriculture, and the Statistical Reporting Service of the U.S. Department of Agriculture obtained quantitative information on bird damage to tart cherries (Prunus mahalob) in Michigan. The results of the survey are presented in this paper.

Madam Saga - An Approach To An Animal Damage Problem, William D. Fitzwater

Bird Control Seminars Proceedings

While human tinkering with the zoogeographical distribution of lower animals sometimes pays dividends, more often it opens up Pandora's box. Such is the case of the Weaver Finch family. This group of birds is characterized by its colonial habits, granivorous appetite which often counters man's best interests, and elaborate nest structures. The House Sparrow (passer domesticus) is a notable exception of the latter trait as its nests look like a Picasso interpretation of an Afro wig. Weaver Finches originated in Africa. Here they are found in their most numerous forms. The Quelea quelea in flocks of several million compete seriously …

The Monk Parakeet In New York, Douglas P. Kibbe, Noel J. Cutright

Bird Control Seminars Proceedings

Attention was focused on the Monk Parakeet (Myiopsitta monachus) in New York State in 1971 when the first successful breeding record was documented for the state although Monk Parakeets had been noticed in New York and New Jersey since 1968 (Bull, 1971). Since 1971 awareness of the bird’s potential for becoming an established species in New York has spread through several segments of the state’s populace. This awareness has been created primarily through two articles in the magazine published by the New York State Department of Environmental Conservation (DEC), The Conservationist (Trimm, 1972) (Trimm, 1973); several articles in popular magazines, …

A Field Test Of Methiocarb Efficacy In Reducing Bird Damage To Michigan Blueberries, Richard A. Dolbeer, Charles R. Ingram, Allen R. Stickley Jr.

Bird Control Seminars Proceedings

Over 20,000 acres of highbush (cultivated) blueberries are grown in the United States (Johnston et al. 1969). The major producing states are Michigan, New Jersey, North Carolina, Washington, Indiana, and Oregon. Bird damage to blueberries is widespread and sometimes severe (Vaile and Moore, 1968; Pearson, 1958; Hayne and Cardinell, 1949; and Schwartze and Alcorn, 1960). Unfortunately, accurate estimates of less from birds are lacking. Non-lethal methods of controlling bird damage are essential since much of the damage is caused by popular song birds protected by Federal law. Scare devices, including exploders and electronic broadcast alarms, are often used with variable …

Two Tests Of The Avian Repellent, Methiocarb, In Michigan Sweet Cherry Orchards, Allen R. Stickley Jr.

Bird Control Seminars Proceedings

Sweet cherries provide a major source of income to Michigan fruit growers. Annual production in Michigan during the period 1963-1971 averaged 44 million pounds, or 18 percent of the national total (Smith, et al. 1973). Bird damage to Michigan cherries is a major problem. Although no figures are available on the extent of sweet cherry damage, Stone (1973) estimated that in 1972 bird damage to Michigan tart cherries amounted to 17.4 percent of the crop. According to growers we interviewed, damage to black sweet cherries is often more severe than to tart cherries. These growers also report some damage to …

Monk Parakeet Damage To Crops In Uruguay And Its Control, Donald F. Mott

Bird Control Seminars Proceedings

The monk parakeet (Myiopsitta monachus) is considered to be a serious agricultural pest in South America. The species is resident in a sizable area from southeast Bolivia, Paraguay, and southern Brazil, through Uruguay, to central Argentina (Meyer de Schauensee, 1970: 103). Since it is hardy, adaptable, and widely sold as a cage bird, there is now concern that large enough populations may become established in the United States to cause damage to grain and fruit crops (Bump, 1971). In April 1973, I visited Uruguay under the sponsorship of the U.S. Agency for International Development (AID) to investigate patterns of agricultural …

The Effects Of Fenthion On A Nesting Population Of Quelea During Experimental Control By Aerial Spraying, Jeffrey J. Jackson, Peter O. Park

Bird Control Seminars Proceedings

Quelea quelea is probably the most important avian pest of cereal crops in the sahelian areas of Africa. Its depredations reduce the cereal production of many African nations that lie within its range. To prevent this damage, bird control organizations carry out campaigns to reduce their numbers. Frequently these efforts have given poor crop protection for the cost of control because of inadequate control technology. Factors contributing to the difficulty of carrying out this kind of control are the migrations of the birds which are still incompletely understood, the inaccessability of many nesting areas, the relatively high reproductive potential of …

Where Are We? - National Scene, Richard N. Smith

Bird Control Seminars Proceedings

When the question is asked, “Where are we?”, we must compare our progress to where we were in the past or to a goal of the future. When we do this, it is apparent that much has been accomplished during the past ten years, however, the goal of alleviating bird damage to all agricultural crops has not yet been met. We have developed methods to combat crop losses (Avitrol, scaring devices), we know more about bird population dynamics, more about bird behavior and physiology. Yet, there is much more to accomplish, for we have a number of bird crop damage …

“Where Are We?”, C. Douglas Mampe

Bird Control Seminars Proceedings

The subject I have been asked to speak on is “Where Are We?” As I assess it, I think that we, those who are using bird management agents and methods, Federal, State, and other agencies representing research, extension and regulatory, and manufacturers of agents used in bird management, are standing in the middle of a busy intersection and the light has just turned yellow. Some of us have tape across our mouths and cotton stuck in our ears. I think that we have arrived at this intersection in a number of different ways. Some of us have taken separate paths, …

Decline Of A Blackbird Population During Seven Years Of Baiting With A Chemical Frightening Agent, Jerome F. Besser, John W. De Grazio, Joseph L. Guarino

Bird Control Seminars Proceedings

In the early 1960's, Sand Lake National Wildlife Refuge, Brown County, South Dakota, served as an assembling area for the largest late summer blackbird congregation known to us in the Norhtern Great Plains or the western portion of the Cornbelt. Approximately 4,000 acres of cattail (Typha) and reed (Phragmites) at the Refuge served as ideal roosting habitat for blackbirds. In August and September each year, postbreeding flocks of blackbirds from northern South Dakota, North Dakota, and Canada assembled to molt in these marshes and to feed on the abundant blackbird foods in the surrounding agricultural lands before migrating to wintering …

Crowding Among Hunter-Gatherers: The !Kung Bushmen, Patricia Draper

Department of Anthropology: Faculty Publications

Highly crowded living conditions exist among the !Kung Bushmen, hunter-gatherers who live on the edges of the Kalahari Desert in Botswana and South-West Africa. The !Kung appear to be crowded by choice, and biological indicators of stress are absent. Data indicate that residential crowding alone does not produce symptoms of pathological stress.

Polyperiod Analyses Of Investment Strategy For Nebraska Grain-Livestock Farms, Glenn A. Helmers, Gary W. Lentz

Nebraska Agricultural Experiment Station: Historical Research Bulletins

This study is directed toward investment strategies farm firms in the Great Plains may utilize to achieve their individual goals. Farm firm growth is considered important to the extent that firm growth represents movement toward meeting the behavioral goals of farm operators.

Potential Insect-Control Applications For Microwaves, Stuart Nelson

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

The idea of using radiofrequency (RF) electric energy for controlling insects is not new. Experiments in the United States to control insects with high-frequency electric fields date back at least 45 years, and reports indicate development of similar interests in Europe during the same period. Many researchers have explored the possibilities since then, and their findings have been reviewed in several publications (Thomas, 1952; Frings, 1952; Peredel'skii, 1956; van den Bruel et al., 1960; Watters, 1962; Nelson, 1966, 1967, 1972, 1973). The purposes in preparing this paper are to summarize these findings in a general way, to discuss some of …

Excavations At Korucutepe, Turkey. Part Ii: The Fortification Wall, Carol Bier

Textile Research Works

Excavations at Korucutepe have brought to light a fortification wall of a type common in Anatolia during the second millennium B.c. The wall had been exposed in places by bulldozing operations for a government farm. Excavation revealed a plan consisting of a curtain wall with a double stone foundation (see fig. 7). Square towers project at intervals where the direction of the wall changes. Adjacent to two of the towers is a passageway, one on the south side of the mound, one on the northeast, leading out from the city. There is no indication of any cross walls, or casemates, …

On The Corpus Of Lysias, Thomas Nelson Winter

Department of Classics and Religious Studies: Faculty Publications

From CLASSICAL TIMES to the present, scholars have been rejecting Lysias' speeches. Their efforts are now complete. In the time of Dionysius of Halicarnassus the Lysian corpus included 425 speeches. Of these, Dionysius averred that "no fewer than 200" juridical orations were the work of Lysias. Including some nonjuridical speeches, he settled upon a total of 230 as genuine works. The scholarship factor and the usual accidents of transmission have left us but thirty-five. This includes two epitomes (orations 11 and 15), three extensive quotations in Dionysius' De Lysia ludicium (orations 32, 33, and 34) and the Eroticus from Plato's …

Sweetclover Weevil: Adenosine As A Feeding Stimulant, G. L. Beland, Francis A. Haskins, G. R. Manglitz, Herman J. Gorz

Department of Agronomy and Horticulture: Faculty Publications

Adult Sitona cylindricoIlis Fåhraeus responded to adenosine in bioassays for feeding-stimulant activity. The molar concentration of adenosine which elicited maximum feeding in the bioassay was less than 1/10 of the sucrose concentration required for maximum feeding. Various purines, pyrimidines, nucleosides, nucleotides, and related compounds were compared with adenosine in bioassays for weevil-feeding stimulant activity. Of all compounds tested, only adenosine triphosphate and adenosine monophosphate appeared to act as feeding stimulants; at the concentrations used, their activities were substantially lower than that of adenosine. Free adenosine was isolated from leaf extracts of weevil-susceptible Melilotus officinalis (L.) Lam. by ion-exchange and paper …

The Effects Of Soil Salinity And Meloidoflyne Javanica On Tomato, Armand R. Maggenti, Adnan Hardan

Harold W. Manter Laboratory of Parasitology: Faculty Publications

A non-sodic, non-saline sandy loam soil was salinized to anion-cation ratios similar to those naturally occurring in Iraq and California. The interactions of saline soils (conductivities 4, 8, 12 and 16 mmhos/cm) with a moderately salt-tolerant plant (Lycopersicon esculentum 'Marimond') and a plant parasitic nematode (Meloidogyne favanica) were investigated. Plant parasitic nematodes were shown to be an important modifying influence within the plant environment, either accentuating or ameliorating salinity stress effects.

Raman Spectrum Of Gadolinium Molybdate Above And Below The Ferroelectric Transition, Frank Ullman, B. J. Holden, B. N. Ganguly, John R. Hardy

John R. Hardy Papers

90 °-scattered Raman spectra of single-domain gadolinium molybdate have been obtained at room temperature and above the 159 °C ferroelectric transition on several crystal orientations. Lines in the 0-200-cm^-1 range can all be associated with Raman-active phonons and are identified by symmetry considerations, scattering-efficiency calculations, and comparison of spectra for different crystal orientations. Lines in the 200-1000-cm^-1 range can be identified with coupled vibrations of tetrahedral molybdate ions. Spectra for frequencies above 1,000 cm^-1 originate from impurity flourescence. The effect of the presence of multiple domains on the spectra was determined; the observed differences between single-domain and …

Rna Polymerase Activity Associated With Bacteriophage Φ6, James L. Van Etten, A. K. Vidaver, R. K. Koski, J. S. Semancik

Department of Plant Pathology: Faculty Publications

The Pseudomonas phaseolicola bacteriophage φ6 incorporated labeled UTP into an acid-insoluble precipitate. Incorporation was dependent on the presence of manganese acetate, ATP, GTP, CTP, and a short heat treatment of the phage; the reaction was stimulated by NH,Cl. The substitution of ¹⁴C-ATP, -CTP or -GTP for UTP, together with the appropriate unlabeled ribonucleoside triphosphates, disclosed that CMP was incorporated to the greatest extent followed by GMP, UMP, and AMP. Radioactive RNAs formed by the reaction were resistant to RNases A and T₁ in high salt but susceptible to these nucleases in low salt. The labeled RNA co-sedimented and …

Characteristics Of Deoxyribonucleic Acid Polymerase Isolated From Spores Of Rhizopus Stolonifer , Cheng-Shung Gong, Larry Dunkle, James L. Van Etten

Department of Plant Pathology: Faculty Publications

Deoxyribonucleic acid (DNA)-dependent DNA polymerase was purified several hundredfold from germinated and ungerminated spores of the fungus Rhizopus stolonifer. The partially purified enzymes from both spore stages exhibited identical characteristics; incorporation of [³H] deoxythymidine monophosphate into DNA required Mg²⁺, DNA, a reducing agent, and the simultaneous presence of deoxyguanosine triphosphate, deoxycytidine triphosphate, and deoxyadenosine triphosphate. Heat-denatured and activated DNAs were better templates than were native DNAs. The buoyant density of the radioactive product of the reaction was similar to that of the template DNA. The enzyme is probably composed of a single polypeptide chain with …
