Starlings In California, Charles C. Siebe Mar 1964

Starlings In California, Charles C. Siebe

Vertebrate Pest Conference Proceedings: 2nd (1964)

In 1959 Dr. Walter E. Howard, in an article printed in the Bulletin of the California Department of Agriculture, stated: "Even though the starling may be unwanted in California, it is now here and there is little chance of extirpating it". This statement is as true today as it was five years ago. At present we have in California a resident population that is increasing each year and will most probably continue to increase. Nesting starlings have been found from Imperial and San Diego Counties in the south to Modoc County in the north. To-date damage has been confined primarily …

The Control Of Vertebrate Problem Animals In The Province Of The Cape Of Good Hope, Republic Of South Africa, Douglas Hey Mar 1964

The Control Of Vertebrate Problem Animals In The Province Of The Cape Of Good Hope, Republic Of South Africa, Douglas Hey

Vertebrate Pest Conference Proceedings: 2nd (1964)

The policy of the Cape Provincial Department of Nature Conservation is based on the concept of "wise management" of wildlife resources. Where crop damage is real, control measures are essential. These, however, must be adapted to the species concerned and applied only where the damage is taking place. Blanket measures which also kill many useful species must be avoided. For this reason, the control of problem animals should be vested in the agency concerned with wildlife conservation.

Pest Control Methods And People, John E. Swift Mar 1964

Pest Control Methods And People, John E. Swift

Vertebrate Pest Conference Proceedings: 2nd (1964)

Frankly I am not sure what "Pest Control Methods and People" really means. When I asked what I should cover, I was told to give a general discussion on pesticides. I am not sure this is appropriate even though the laws and regulations that pertain to other pesticides apply equally to those materials used in vertebrate pest control; the conditions of use, the types of chemicals used, their effect upon various animal species, and the number of chemicals available are so different from the pesticides used in controlling invertebrate pests that generalizations may not cover the topic. There are, however, …

Methods Of Controlling Blackbird Damage To Field Corn In South Dakota, John W. De Grazio Mar 1964

Methods Of Controlling Blackbird Damage To Field Corn In South Dakota, John W. De Grazio

Vertebrate Pest Conference Proceedings: 2nd (1964)

One of the most widespread bird problems in the Western United States is damage to ripening cereal grain crops. Crops such as corn, rice, and sorghum, when grown close to favored roosting areas are often subject to serious damage from large flocks of feeding blackbirds. The redwinged blackbird is the most numerous species and causes most of the damage, but other blackbird species, including the yellow-headed blackbird, the common grackle, the brown-headed cowbird, and Brewer's blackbird, also contribute to damage problems. The Denver Wildlife Research Center is actively investigating methods to combat blackbird depredations to field corn in the vicinity …

Bats: Their Public Health Importance And Control With Special Reference To Trinidad, Arthur M. Greenhall Mar 1964

Bats: Their Public Health Importance And Control With Special Reference To Trinidad, Arthur M. Greenhall

Vertebrate Pest Conference Proceedings: 2nd (1964)

This brief review of the public health importance and control of bats is oriented to Trinidad, where, during the past ten years I investigated their zoomedical importance (1). Trinidad is noted for Pawan's classic epidemiological studies of bat rabies (2,3) as well as its bat control program with which I have been associated since its inception in 1934 (4). Further, Trinidad has bat problems, in addition to rabies, which occur in other countries of the world. Although various methods of bat control have been developed in Trinidad, the field is virtually unexplored. Increasingly, bat control is a matter of paramount …

Sound In Vertebrate Pest Control, Hubert Frings Mar 1964

Sound In Vertebrate Pest Control, Hubert Frings

Vertebrate Pest Conference Proceedings: 2nd (1964)

The best known vertebrate pests, as the papers presented at this meeting show, are birds and mammals. Other vertebrates, however, may become pests also: sharks, lampreys, toads (they fall into swimming pools), geckos, tortoises and snakes, for example. Without considering them, however, the depredations by birds and mammals alone are so varied that no single method of pest control can ever be all-embracing. Certainly, no one would suggest that acoustical methods would be, but, with further study, acoustical pest control should be much more widely used. I hope to point out here the possibilities and a few realities in bio-acoustics …

Hawaiian Sugar Cane Rat Control Methods And Problems, William R. Smythe Mar 1964

Hawaiian Sugar Cane Rat Control Methods And Problems, William R. Smythe

Vertebrate Pest Conference Proceedings: 2nd (1964)

The problem of rats in our Hawaiian sugar cane fields has been with us for a long time. Early records tell of heavy damage at various times on all the islands where sugar cane is grown. Many methods were tried to control these rats. Trapping was once used as a control measure, a bounty was used for a time, gangs of dogs were trained to catch the rats as the cane was harvested. Many kinds of baits and poisons were used. All of these methods were of some value as long as labor was cheap. Our present day problem started …

Roof Rat Populations In Santa Clara County, California, Dean H. Ecke Mar 1964

Roof Rat Populations In Santa Clara County, California, Dean H. Ecke

Vertebrate Pest Conference Proceedings: 2nd (1964)

Northern Santa Clara County, California, was historically an agricultural community with orchard culture dominating the economy. Prunes, apricots, walnuts, and cherries were the principal crops. Orchards were disced clean during most of the summer growing season, and a cover crop of mustard or horse beans was grown beneath the trees in winter. About the only "natural" year around cover on the valley floor was the brush and grass which volunteered along the several creek banks. Under such conditions, roof rats (Rattus rattus) were not numerous. An occasional rat colony could be found in a fruit processing shed or …

Occupational Hazards To Pest Control Operators With Special Reference To Pesticides, Irma West Mar 1964

Occupational Hazards To Pest Control Operators With Special Reference To Pesticides, Irma West

Vertebrate Pest Conference Proceedings: 2nd (1964)

With the help of one of your expert operators I have selected eight pesticides which I understand are widely used in vertebrate pest control, and with one exception, pose substantial safety problems for operators. These pesticides are the anticoagulants, zinc phosphide, 1080, strychnine, thallium sulfate, anhydrous ammonia, carbon disulfide, and methyl bromide. Except for the anticoagulants, it would be hard to assemble a more lethal group of chemicals. I wonder if the talents of chemical research should not be brought into this picture more actively, so that less hazardous materials could be developed for vertebrate pest control. Perhaps the economic …

Diseases Derived From Wildlife, Harald Norlin Johnson M.D. Mar 1964

Diseases Derived From Wildlife, Harald Norlin Johnson M.D.

Vertebrate Pest Conference Proceedings: 2nd (1964)

The specific diseases of man known to be derived from wildlife in California are: rabies, Western encephalitis, St. Louis encephalitis, Colorado tick fever, Rocky Mountain spotted fever, relapsing fever, 0. fever, plague, tularemia, murine typhus, lymphocytic choriomeningitis, psittacosis, leptospirosis, salmonellosis and toxoplasmosis. A variety of bacterial infections may be contracted from wild animals, notably those caused by Pasteurella pseudotuberculosis, Pasteurella multocida, Bacillus anthracis, Erysipelothrix rhusiopathiae, Clostridium tetani and Listerella monocyto-genes. Certain of the fungus diseases such as coccidioidomycosis and histoplasmosis are derived from exposure to wildlife habitats. California virus has been isolated from arthropods and Rio Bravo virus from bats …

Animal Population Ecology And Control Fundamentals, Kenneth E. F. Watt Mar 1964

Animal Population Ecology And Control Fundamentals, Kenneth E. F. Watt

Vertebrate Pest Conference Proceedings: 2nd (1964)

Expensive, extensive and apparently lethal control measures have been applied against many species of pest vertebrates and invertebrates for decades. In spite of this, few pests have been annihilated, and in many cases the stated goals have become progressively more modest, so that now we speak of saving foliage or a crop, rather than extermination. It is of interest to examine the reasons why animals are so difficult to exterminate, because this matter, of course, has implications for the type of control policy we pursue in the future. Also, it has implications for the problem of evaluating comparatively various resource …

The Role Of Pest Control Operators In Vertebrate Pest Control, Philip J. Spear Mar 1964

The Role Of Pest Control Operators In Vertebrate Pest Control, Philip J. Spear

Vertebrate Pest Conference Proceedings: 2nd (1964)

The National Pest Control Association, which I represent, accepts for membership those persons or firms which are actively engaged in the performance of structural pest control services for hire to the public at large and which are in sympathy with the purposes of the Association. The pest control operator in this context might be called a commercial pest control operator to distinguish him from those doing similar work but who are employed by governmental agencies or within large commercial organizations. Pest control is a growing industry with a gross annual income of 300-350 million dollars. It is estimated to contain …

Starlings In The Pacific Northwest, H. Nelson Elliott Mar 1964

Starlings In The Pacific Northwest, H. Nelson Elliott

Vertebrate Pest Conference Proceedings: 2nd (1964)

As is the case in many sections of the country today, starlings are causing increasing concern in the Pacific Northwest. When these birds were first recognized in Washington, Oregon and Idaho in the early 1940's only small numbers were seen, usually with blackbirds. During the 50's, however, the number of wintering starlings increased from a few birds, to thousands, with estimated flocks of 25,000 to 50,000 in western Oregon and along the Snake River Valley in Idaho and eastern Oregon. During the past five years winter resident populations in these areas have been estimated by the 100,000's, with some observers …

Testing And Registration Of New Control Materials, Donald A. Spencer Mar 1964

Testing And Registration Of New Control Materials, Donald A. Spencer

Vertebrate Pest Conference Proceedings: 2nd (1964)

The Federal Insecticide, Fungicide, and Rodenticide Act broadly encompasses, " any substance or mixture of substances intended for pre¬ venting, destroying, repelling, or mitigating...." a pest. The act includes devices as well as chemicals used in the control of pests. It is the responsibility of the manufacturer to provide authoritative evidence of the efficacy and safety of his pesticide product. Within the scope of these four brief excerpts from the act there is much about which personnel engaged in research and development of vertebrate pest control products should be informed. As stated, the coverage of the act is very complete, …

The Role Of Industry In Developing New Materials For Vertebrate Pest Control, G. Hermann, W. M. Zeck Mar 1964

The Role Of Industry In Developing New Materials For Vertebrate Pest Control, G. Hermann, W. M. Zeck

Vertebrate Pest Conference Proceedings: 2nd (1964)

In the first paper presented to you today by Dr. Spencer, an expert in the Animal Biology field and an official authority at the same time, you heard about the requirements imposed on a chemical in order to pass the different official hurdles before it ever will be accepted as a proven tool in wildlife management. Many characteristics have to be known and highly sophisticated tests have to be run. In many instances the governmental agency maintains its own screening, testing or analytical programs according to standard procedures. It would be impossible, however, for economic and time reasons to work …

The Natural Propagation Of Northern Pike In Small Drainable Ponds, D. B. Mccarraher Jan 1964

The Natural Propagation Of Northern Pike In Small Drainable Ponds, D. B. Mccarraher

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

To obtain information on the hatching success and fingerling survival of the northern pike (Esox lucius) in small drainable ponds, experiments were initiated at the State Fish Hatchery, Valentine, Nebraska, during the spring seasons of 1955 and 1956.

All the ponds used in this work were winter-fallowed, providing areas without fish populations. At no time in 1955 or 1956 were forage fish added to the ponds.

Adult spawner pike for the ponds were obtained from Mothers Lake (in Cherry County, Nebraska) in 1955 and from Big Alkali Lake (also in Cherry County) during 1956. All breeder pike were …

Breeder Reactors, Lloyd G. Alexander

United States Department of Energy: Publications

Energy from nuclear sources will contribute substantially toward meeting the world's power requirements by the end of this century and possibly will dominate by the middle of the next. While it is hoped that the fusion of hydrogen or deuterium will ultimately provide energy at negligible cost, this is not certain; and present efforts are directed mainly toward the develop­ ment of reactors wherein nuclear energy is released by the neutron-induced fission of certain isotopes of uranium and plutonium.

Waterfowl Drive-Trap Banding, Gene Goecke Jan 1964

Waterfowl Drive-Trap Banding, Gene Goecke

Other Publications in Wildlife Management

During a 3-week period in July of 1964, Game Section personnel with assistance from Biology Section and Conservation Officer personnel carried out drive-trap waterfowl banding operations on marsh areas in the northern part of Iowa. This was the fourth year that drive-trap banding operations have been carried out in the state. Several days prior to the actual banding operations were spent selecting areas to band. Areas were selected that had a good population of local birds and vegetative cover suitable for banding. Young birds can be extremely difficult to drive on heavily vegetated marshes of emergent vegetation, and marshes lacking …

Recent Limnological Studies Of The Alkaline Lakes In Nebraska And North Dakota, D. B. Mccarraher Jan 1964

Recent Limnological Studies Of The Alkaline Lakes In Nebraska And North Dakota, D. B. Mccarraher

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

Environmental relationships and biological indices have been recorded for 1,200 sandhills lakes in Nebraska since 1954. Three lakes in central and southern North Dakota were investigated during the years 1963 to 1964. Most of the Nebraska lakes were alkaline eutrophic of the sodium bicarbonate and sodium + potassium carbonate types. The North Dakota lakes range from sodium bicarbonate to sodium sulfate types. These lakes may be classified as saline eutrohpic. The ionic composition differs from that of the marine and inland sodium chloride type of water. The invertebrate fauna of permanently alkaline environments are discussed from the point of view …

Preliminary Studies In The Development Of A Gastric Battery For Fish, Earl R. Kendle, Larry A. Morris Jan 1964

Preliminary Studies In The Development Of A Gastric Battery For Fish, Earl R. Kendle, Larry A. Morris

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

In 1956 Parker S. Trefethen described an external ultrasonic tag for tracking fish. This tag was designed for use on adult king salmon, Oncorhynchus tshawytsca, and was subsequently used to track these fish above Bonneville Dam (Johnson, 1957). Although this tracking system was the best available at that time several limitations to its use were evident: the transmitter and power supply were large and thus impractical for use on small fish, and the unit was attached externally and was likely to influence movement, and the life of the battery was very short (17 hours). Succeeding transmitters were somewhat longer-lived …
