Epa Registration Requirements For Orchard Rodenticides And The Manufacturer's Development Conslderations, D. L. Peardon

Eastern Pine and Meadow Vole Symposia

Data requirements for the registration of pesticides in the United States, and other countries, have been increasing steadily over the past 25 years. Requirements have increased fastest during the past 5 years.

The Role Of The Fish And Wildlife Service Research In Solving The Eastern Pine Vole/Orchard Problem, Richard N. Smith

Eastern Pine and Meadow Vole Symposia

Many orchardists, nurserymen and Christmas tree grcwers, State extension agents, and a few Fish and Wildlife Service people are aware of the economic problems that pine voles (microtus pinetorum) cause to orchards in the Appalachian Regions of the United States. This is expected for these people have had to deal first hand with economic losses caused by these small mammals. What is unusual and somewhat discouraging is that this problem was identified over forty years ago and that we really know little more about this animal now than we did then.

A Matter Of Survival, S. Pitchon

Eastern Pine and Meadow Vole Symposia

Session V of the program calls for "Chemical Industry Positions on Economics of Rodenticides". I will attempt to describe some of the problems that industry faces in registering pesticides and how they affect the cost and delay registration.

Some Pine Vole Movement Patterns In Several Apple Orchards In Henderson County, North Carolina, William T. Sullivan

Eastern Pine and Meadow Vole Symposia

In controlling pine voles in orchards a question often comes up about the distance the voles will move from outside into an orchard where the resident animals have been removed by a control program. There are several possible ways to study this, but at present the closest we can come to an answer is to see how far animals move in live-trapping studies. Naturalists have raised many questions about how to interpret these observations of trapped animals. For example, maybe movements are farther or more frequent into areas which have no resident animals or perhaps the animals that move in …

Pine Voles (Pitymys Pinetorum) And Orchard Damage Research: An Overview Of The N.Y. Coop Wildlife Research Program In Animal Damage, Milo Richmond, Robert Stehn, Mary Dunlay

Eastern Pine and Meadow Vole Symposia

We began our research effort in 1968 with a project aimed at determining the efficacy of endrin treatment for pine vole control. Grower concerns and a small amount of laboratory data indicated that endrin was no longer as reliable in controlling pine voles as it was in the early sixties. Our initial efforts were twofold. We sought first to determine the existing efficacy of endrin and secondly to evaluate any resistance by pine voles to this chemical control procedure. Unfortunately, this entire endrin research effort was dropped by the Cooperative Research Unit when endrin as well as other persistent chlorinated …

Control Of Microtus In Two Damage Situations, Andrew Radvanyi

Eastern Pine and Meadow Vole Symposia

In Canada the potential exists of over a million dollars girdling damage loss per year caused by small mammals to fruit trees in each of the four major orchard areas of British Columbia, Ontario, Quebec and Nova Scotia. Such annual losses continue to occur despite the existence of methods developed which could largely eliminate a large percentage of such losses at a fraction of the costs currently being spent on attempts to control small mammal populations (primarily meadow voles (Microtus pennsylvanicus) in orchard situations. In this paper I propose to outline briefly the developmental studies conducted by the …

"Mouse-Ateria" - A Bait Station For Rodents, Bruce Porterfield, Henry J. Eavis

Eastern Pine and Meadow Vole Symposia

In 1918 the first device of this kind was designed near Winchester, Virginia. In 1973 we introduced a high strength Styrene plastic version of it, copied from the hand-blown glass model.

Remarks To Be Presented At The First Eastern Pine And Meadow Vole Symposium, Merle H. Markley

Eastern Pine and Meadow Vole Symposia

A Rebuttable Presumption Against Reregistration has been issued against endrin. It is my own opinion that: First endrin should be critically examined, use by use, with respect to effectiveness and alleged hazard to non-target animals, be they pets, domestic stock or wildlife; and secondly, that a careful and complete review be made of all economic benefits against the hazards identified in the earlier review. The notice which appeared in the Federal Register emphasized the occasional harmful aspects of use and failed to give much or any credence to benefits. Certainly there must be some value to the grower and financial …

Exceptions To The Rule: A Review Of The Criminal Personality, Volume I: A Profile For Change, Richard A. Dienstbier

Department of Psychology: Faculty Publications

The major purpose of the first volume of an intended three-volume series by Samuel Yochelson and Stanton E. Samenow (1976) is to provide evidence that understanding the thought processes of chronic criminals provides the major key to understanding criminal behavior. Volumes II and III will deal, respectively, with the techniques of therapy developed for the analysis and correction of criminal thought patterns, and with the special problems of therapy with criminals who are chronic drug users. This review of Volume I is divided into three parts, the first being a review of the content and major points of the book, …

Growing Degree Days Predictions For Corn And Sorghum Development And Some Applications To Crop Production In Nebraska, R. E. Neild, M. W. Seeley

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The concept of growing degree days (GDD) originated with observations by Reamur (1735) that plant development is more closely related to the temperature accumulated to a given stage than with time alone. It was not until nearly 200 years later, however, that Merriam (1894), Livingston (1916) and Klages (1942) began to use temperature accumulations in plant distribution studies and in crop geography. In the early 1950's, a system involving growing degree days became widely used in the canning industry to schedule plantings and thus control time of harvest of rapidly maturing vegetables. This system provided a more precise control of …

"Introduction" To The Great Plains: Environment And Culture, Frederick C. Luebke

Department of History: Faculty Publications

In the pages that follow I have summarized the views of certain selected scholars whose emphases seem to illustrate changing and contrasting interpretations of the interaction of environment and culture on the Great Plains. I have grouped their writings into two inclusive categories. First come those whose conceptual schemes suggest the primacy of environmental variables. I refer to these scholars, perhaps simplistically, as environmentalists, even though this term has acquired a different meaning in recent years. In the second group are several scholars, selected more arbitrarily than the first, whose writings seem to accord more importance to cultural factors. For …

G77-339 Price Spreads For Beef And Pork, Allen C. Wellman

University of Nebraska-Lincoln Extension: Historical Materials

The price spreads for beef and pork are determined by calculating the differences between prices at three marketing levels: farm (live animals), wholesale (carcass or wholesale cuts), and retail (average of retail cuts). Three price spreads, farm-wholesale, wholesale-retail, and farm-retail can be estimated from these prices. Farm-to-retail price spreads for beef and pork represent the total marketnig charges for processing and distribution from farm gate through retail counter and are discussed in this NebGuide.

G77-350 Mineral Nutrition Of Range Beef Cattle, Marvin W. Heeney

University of Nebraska-Lincoln Extension: Historical Materials

Minerals play a very important role in the well-being of the range beef herd. Minerals are essential for practically all of the metabolic functions of the beef animals. Minerals are classified as 1) major and 2) minor or trace. The major minerals include calcium, phosphorus, magnesium, sodium, potassium, chlorine and sulfur. The trace minerals include copper, cobalt, iodine, iron, manganese and zinc.

Each mineral is discussed here in terms of its function, deficiency symptoms and availability in the range beef cattle diet.

G77-355 A Guide For The Control Of Flies In Nebraska Feedlots And Dairies (Revised March 1990), John B. Campbell

University of Nebraska-Lincoln Extension: Historical Materials

Flies, especially stable and house flies, can create serious and costly problems for feedlot and dairy operations. This publication describes several methods for control.

Several species of flies may be in confined livestock facilities during summer. The stable and house fly are the most serious pests. Blow flies also may be present if molasses is in the diet. Horn flies--small blood-feeding flies--may be present in early spring. These flies overwinter as pupae in or near manure pats in range or pasture. If cattle are not present in the grassland when horn flies emerge, they will migrate to confinement cattle. Normally, …

Vibriosis In Fish, G. L. Bullock

United States Fish and Wildlife Service: Publications

Fish vibriosis is a systemic disease of marine, estuarine, and some freshwater fishes, caused by bacteria of the genus Vibrio (Ross et al. 1968, Ghittino et al. 1972). The disease has been known for centuries; outbreaks along the Italian coast were recorded as early as the 1500's. Terms such as "red pest," "red boil," "red plague," or "saltwater furunculosis" have been applied to vibrio infections, but vibriosis is a more specific term and is now used by most fishery workers. With the rapid development of mariculture, vibriosis has become a major cause of fish loss--sometimes to the extent of being …

Upland Nesting Of American Bitterns, Marsh Hawks, And Short-Eared Owls, Harold F. Duebbert, John T. Lokemoen

United States Fish and Wildlife Service: Publications

Nests of American Bitterns (Botaurus lentiginosus), marsh hawks (Circus cyaneus), and short-eared owls (Asio flammeus) are usually found in wetland habitats. Although large marshes containing dense stands of bulrushes (Scirpus), cattails (Typha), or other wetland vegetation are favored nesting cover, these birds have also been reported to nest in stands of tall, dense shrubs and grasses on the upland (Bent 1961, 1963; Palmer 1962; Sealy 1967; Stewart 1975). During 1968-74, we regularly found upland nests of these three species while conducting duck nesting studies in planted fields of undisturbed grass-legume …

G77-363 Vitamin Requirements Of Beef Cattle, Paul Q. Guyer

University of Nebraska-Lincoln Extension: Historical Materials

Vitamins are organic substances that are required in very small quantities for various metabolic functions. Twenty-five to 30 have been identified, but cattle can synthesize all that are needed of these vitamins in the rumen except for two or three. Even though the supplemental amounts needed of these two or three vitamins (A and possibly D and E) are quite small, a deficiency can have a drastic effect on the animal. The NebGuide discusses these effects.

Inventory Of Wetland Habitat Usig Remote Sensing For The Proposed Oahe Irrigation Unit In Eastern South Dakota, Robert G. Best, Donald G. Moore

United States Fish and Wildlife Service: Publications

An inventory of wetlands for the area included in the proposed Oahe Irrigation Project was conducted to provide supplemental data for the wildlife mitigation plan. This report including the data summaries follows a report which documented the interpretation techniques as presented by Best, Moore, and Brewster for inventoryinq small, predominantly Type I wetlands in the low-relief terrain of the Lake Dakota Plain. Wetland habitat in over 310,000 acres in the Oahe irrigation district was inventoried. There were 5305 wetlands representing 7530 acres, 589 acres of natural drains, and 1545 acres of stream habitat in the area. The data were stored …

Nesting By Ferruginous Hawks And Other Raptors On High Voltage Powerline Towers, David S. Gilmer, John M. Wiehe

United States Fish and Wildlife Service: Publications

High voltage powerlines form a spider-web pattern across North Dakota as they radiate outward from electric generating sources at Garrison Dam and nearby lignite-fired power plants. In 1976 there were approximately 1100 miles of high voltage powerline in the state, which required approximately 4500 large steel or aluminum towers for support (G. R. Anderson, personal communication). Moreover, officials of power cooperatives and privately-owned utilities anticipate the construction of over 900 additional miles of high voltage lines by 1981. As North Dakota coal resources are developed the powerline network will probably continue to grow.

Our interest in powerlines was stimulated several …

G77-331 Sampling Feeds For Analyses, Bruce Anderson, Terry L. Mader, Rick Grant

University of Nebraska-Lincoln Extension: Historical Materials

Sampling is the key to accurate feed analyses and properly balancing livestock rations. Here's how to do it.

Accurate feed analyses are needed to balance livestock rations, correctly price hay, formulate least cost supplements, and efficiently allocate homegrown feeds to the proper class of livestock. Sampling is the most important factor affecting accuracy of feed analyses.

The feed value of most forages varies. Therefore, test forages routinely to determine their best and most economical use. With adequate forage testing, you can develop an accurate forage inventory which allows you to efficiently allocate higher quality forage to high-producing livestock and poorer …

Argulus, A Branchiuran Parasite Of Freshwater Fishes, G. L. Hoffman

United States Fish and Wildlife Service: Publications

"Fish lice" of the genus Argulus (suborder Branchiura) are Common parasites of freshwater fish, and may occur on frogs and salamanders. Argulids often cause severe mortality of fish in farm ponds, and sometimes in natural waters. Because information on life cycles, ecology, and host specificity is incomplete only a generalized account can be given.
