Federal Labeling Standards For Economic Poisons, Paul M. Ochs

Bird Control Seminars Proceedings

The U.S. Department of Agriculture, Pesticide Regulation Division, has the responsibility of administering the Federal Insecticide, Fungicide and Rodenticide Act of 1947 as amended. The Act encompasses any substance or mixture of substances intended for "preventing, destroying, repelling or mitigating any insects, rodents or any other vertebrate animals, nematodes, fungi, weeds, and any other forms of plants or animal life or viruses," except viruses on or in living man or other animals. These products must be registered if they are to be marketed or shipped in interstate commerce, imported or exported, or sold in the District of Columbia or any …

Status Of Starlicide, Philip J. Spear

Bird Control Seminars Proceedings

Starlicide is described as a slow-acting avicide for the control of starlings and blackbirds around livestock and poultry operations. The active ingredient is 3 -chloro-p-toluidine hydrochloride which has been identified by the Denver Re-search Center of the U.S. Fish and Wildlife Service as DRC-1339. A casual review of information about this bird control material suggests the following paradoxes: The use of the chemical in bird control appears to be covered by a patent, but the licensor wishes to remain anonymous. The licensee, which produces and sells the commercial material, seems unwilling to discuss the product. Let me hasten to point …

Bird Control Under A State Fish And Game Permit System, James Shepard

Bird Control Seminars Proceedings

I guess the impetus for laws in our state, really was the action of the city of Boston in 1963, when the Parks and Recreation Department felt that it was time to do something about massive populations of pigeons on the Boston Commons and in the city. The Parks Department came to our agency to find out what could be done. We immediately found as a result of a reorganization and recodification of the laws some 20 years before, that it was illegal to use or apply poisons for the purpose of killing any birds or mammals in the Commonwealth …

Cooperation Between Pest Control Operators And Regulatory Authorities, Robert M. Russell

Bird Control Seminars Proceedings

When Dr. Jackson called me to speak on the rights of the individual I told him he probably had the wrong person because I am an individual and I believe my company is an organization very prone to say "what is, is and you've got to go on with it." If I'd have heard some of the talks here today before he called me, I wouldn't be here at all, because I'm not sure what individual rights there are left! So let me change this thing around a little bit and state that instead of speaking of the rights of …

Drc-1339 In Feedlots, John W. Degrazio

Bird Control Seminars Proceedings

Since 1960, the Denver Wildlife Research Center has been investigating methods of controlling starlings (Sturnus vulgaris) at livestock feedlots. One chemical developed at the Denver Center is a slow-acting avicide, DRC-1339 (3-chloro-p-toluidine); it is well accepted and highly toxic to starlings, generally less toxic to other birds, and relatively nontoxic to mammals. It possesses no secondary hazard to avian and mammalian predators. A Cooper's hawk (Accipiter cooperii), a marsh hawk (Circus cyaneus), and a sparrow hawk (Falco sparverius) subsisted on field-killed DRC-1339 starlings for 3- and 4-month periods with no ill effects. In our tests, poultry pellets (Purina Layena Checkers') …

Costs Of New Materials: The Manufacturer's Dilemma, Dan Macdougall

Bird Control Seminars Proceedings

I thought it was possible that some of you might not be acquainted with some of the frustrations which are involved in jousting with the bureaucracy in Washington. So I thought I would review that situation very briefly for you, particularly in regard to the compound Queletox. We will confess that we had some real qualms about accepting this material for control as a bird toxicant initially. And the reasons we were concerned about this were because the compound was being used in other areas as an agricultural chemical. It was registered for mosquito control, and it was being used …

New Materials For Bird Control, John W. Degrazio, Philip J. Spear

Bird Control Seminars Proceedings

A variety of methods is necessary to solve the many bird damage problems that occur in agriculture and other fields of interest. It is apparent that no one method can be used to provide answers for all damage situations; each problem and problem area is unique and requires thorough knowledge and investigation before intelligent measures of bird control can be applied. Thus, basic research in the laboratory and initial field studies are necessary to arrive at the most safe, efficient, and economical method of bird damage control possible for each situa-tion. The use of chemicals for damage control is one …

Bait And Bait Materials, Fred R. Courtsal

Bird Control Seminars Proceedings

I'm going to speak about bird baits that are produced by the rodent-control fund. In my estimation, there are about six criteria for mixing good, high quality bait materials. The first one would be a toxicant. This is the first thing people talk or think about. I would assume that you would select a toxicant that has the quality to do the intended job. The second point is the sticker. So our criteria for a sticker are as follows: good adhering qualities, good spreading qualities (by this I mean if you introduce the toxicant into a sticker as is often …

Roost Treatments Using 3-Chloro P-Toluidine Hydrochloride, Robert Schwab

Bird Control Seminars Proceedings

Pest birds cause serious damage to agricultural crops in most situations only when the number of individuals is very high. Often, large populations of avian pest species spend the hours of darkness congregated in roosts where they become vulnerable to certain control methods. Such is the case in California where certain pest species, particularity starlings and blackbirds, can often be found roosting in cattail-tule marshes. From these relatively concentrated populations the birds disperse to cause in some, but not all, cases of serious damage to certain agricultural crops. The obvious disadvantage resulting from the tendency of these birds to concentrate …

Utility Of Pyrotechnics In Bird Control, John R. Beck

Bird Control Seminars Proceedings

The balanced approach is essential for the proposed application of control methods for birds. The essential ingredients in a balanced approach are knowledge of the environment, both animal, plant and human; reasonable experience in the solution of biological problems; and an awareness of the possible solutions available. After these problems' qualifying ingredients have been met, the control specialist or investigator may apply the tool of choice. In most instances he will have selected alternatives available to himself. In the selection of the tool of choice and alternative methods, the cost of time, labor, materials and equipment, the need or purpose …

Chemosterilants And Bird Control, M. R. Woulfe

Bird Control Seminars Proceedings

The total scope of chemosterilants is very wide so I will comment only on the pigeon chemosterilant developed by G.D. Searle & Co. and then briefly on the role of chemosterilants, generally, in bird control. Searle's ORNITROL (SC-12937, azacosterol) is a chemosterilant which in-hibits reproduction in the pigeon and is to be used as a means of controlling pigeon populations. It is fed as a treated whole corn bait (0.1%) for a period of ten days and inhibits reproduction for about six months. We recommend treat-ment in the early spring just before the onset of the peak reproduction season to …

Birds, Encephalitis, And Ectoparasites, Margaret A. Parsons

Bird Control Seminars Proceedings

Encephalitis or "inflammation of the brain" is a general term applied to a disorder which may have many causes. Usually this disorder is caused by a virus but it may also be produced by other types of micro-organisms. Encephalitis may also occur after an initial infection with mumps, measles and other childhood diseases, or following a vaccination, or as a result of a non-infectious process such as poisoning. Since encephalitis affects the brain, which in turn controls all body functions, encephalitis from any cause can show symptoms of general illness throughout the body such as headache, nausea and vomiting, fever, …

Status Of Bio-Sonics In Pest Bird Control, Gordon W. Boudreau

Bird Control Seminars Proceedings

Bioacoustics is defined as the study of biologically significant sounds ori-ginated by animals, and the mechanisms which produce and receive these sounds. Many of these sounds are audible to the human ear but some are above the human hearing range and fall into the ultrasonics class. There are sounds used by animals which are near or below the normal human hearing range in pitch, as in certain fish. Bioacoustics comprises a broad field of investigation and is an area which has only recently been explored. Improvements in electronic audio equipment have provided the impetus which launched recent bioacoustical investigations and …

Daily And Seasonal Susceptibility Cycles Of The Starling, Robert G. Schwab

Bird Control Seminars Proceedings

I would like to review a few of the characteristics of 3-chloro-p-toluidine hydrochloride (DRC-1339) prior to discussion on the daily and seasonal suscep-tibility of starlings to this avicide. DRC-1339 was screened and developed by the Denver Research Center (U.S.D.I.) and since has been tested in various portions of the country by the Denver Center and other organizations, including the State of California. In California we are much impressed with this compound for a variety of reasons, particularly the specificity of it to birds, ease in handling, ease in formulation, and many other characteristics which make this a highly desirable avicide. …

The Role Of Fda In Environmental Contamination And Surveillance , Clifford Shane

Bird Control Seminars Proceedings

The Food & Drug Administration is concerned about birds in two areas. One is the direct contamination of foods, drugs and cosmetics by birds and the other is the possible contamination of these products by the chemicals used to control birds. Since its conception, the Food & Drug Administration has been concerned about the contamination of foodstuffs by birds. Like all animals, they have both their good and bad points. The one bad point is that they are carriers of certain diseases. In addition, the consumer of today is not ready to accept products which have been contaminated by fecal …

Sodium Fluoride In Feedlot Starling Control, James Steckel

Bird Control Seminars Proceedings

I'm going to talk about the toxicant, sodium fluoride. This, of course, is not new to anybody who's been in the pest control business. It's very common and is a material that is readily available to industry wherever you might be— sodium fluoride, NaF. Sodium fluoride was a material used in veterinary practice in its early days as a worming agent. When the first problems developed with the swine feeders, particularly with TGE (transmissible gastroenteritis), they were needing a toxicant that they could use to control the birds that were stealing feed out of the food bunkers and leaving their …

Orchard Bird Control With Decoy Traps, Bill Shake

Bird Control Seminars Proceedings

crops. With one method, we tried to see if we could reduce redwinged blackbird damage to corn. We put up the larger traps-25 x 50 or 50 x 100 feet-near corn fields that were being heavily hit or next to marshes where birds are roosting. Although we captured thousands of birds and destroyed them, we were working with such large numbers of birds that we found it was actually like pouring sand effect at all in reducing damage to corn. Also it's not an efficient method in this type of a situation; it takes a lot of time to tend …

Pest Birds And Modern Architecture, Michael W. Fall, David E. Schneider

Bird Control Seminars Proceedings

We are offering some remarks on what the entomologist would call the areas of cultural control. Our interest in this approach developed out of a series of information discussions we've had concerning regional planning pro-grams at Penn State. Our ideas on the applications of this to bird management are not well developed; we'd be happy to hear your suggestions and comments. The ideas of cultural control are not new and are only one of many approaches. But perhaps we are reaching a stage of public concern about bird problems and about environmental contamination which make the climate for long range …

Keep your city clean: Eat a Pigeon

Presession Seminar On Blackbird Problems, Tom Stockdale

Bird Control Seminars Proceedings

I'd like to open with a very brief discussion, then call on some selected people with whom I've corresponded earlier, and ask if they will discuss a particular aspect of this total bird problem. I've asked that they keep their comments from three to five minutes. Trying to break the total problem down into its several facets we came up with six arbitrary subtopics. For want of better terms I've called these: population census techniques, chemical repellants, sonic repellants, wetting agents, lethal control techni-ques, and damage evaluation. Your particular problem in your area may be slightly different than in other …

The Effect Of Thiamine And Its Antagonists On Plasma And Tissue Lactic Dehydrogenase In Rats, Dong Hwa Park

Theses and Dissertations

The lactic dehydrogenase activity in plasma and tissues was measured in the thiamine-deprived, the oxythiamine-treated and the pyrithiamine-treated rats as well as the control rats. The lactic dehydrogenase levels of brain and kidney were significantly increased by oxythiamine treatment. The enzyme activity in heart was markedly decreased only in the thiamine-deprived rats. Unlike the above tissues, the enzyme levels in liver were decreased by 29-44 per cent in all three types of thiamine deficiency, However, the enzyme activity in plasma was significantly increased only by pyrithiamine administration. The distribution patterns of lactic dehydrogenase isozymes were electrophoretically examined in these deficiencies. …

Concurrent Infections Of Schistosoma Mansoni And Trypanosoma Equiperdum In Mice, Venus Ee-Siriporn

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this investigation was to determine factors which may influence the survival time of mice infected with Trypanosoma equiperdum and the effects of T. equiperdum on mice infected with Schistosoma mansoni.

In order to maintain experimentally obtained standard hours of survival (88 hrs) in mice inoculated intraperitoneally with 150,000 T. equiperdum, it was found that trypanosomes removed from the donor rat should be kept at 25 C and all counts, dilutions of the organisms, and injection should be completed within 1 hour after removal from the donor host. Survival time of mice is increased as the …

Craniofacial Changes Resulting From Expansion Of The Midpalatal Suture In The Macaca Mulatta Monkey As Revealed By Roentgenographic Analysis, Raymond M. Sugiyama

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to determine the effects of midpalatal suture separation on the craniofacial complex by quantitative roentgenographic analysis.

Ten female Macaca mulatta monkeys were randomly grouped for experimentation. Six animals were paired in groups for two months of treatment, four months of treatment followed by two months of post retention, and six months of treatment. The four remaining monkeys were paired and served as control animals for two and six month periods. Total activation of the expansion appliances in the treated animals was completed over a three week period.

The findings of this study were based …

Masseter Muscle Position Relative To Skeletal Open Bite And Skeletal Closed Bite, Alonzo David Proctor

Loma Linda University Electronic Theses, Dissertations & Projects

Modification of cephalometric roentgenographic procedures provided a means to identify the anterior borders of the right and left masseter muscles and relate them to surrounding dentoskeletal elements. Attachment of short, stiff, wires to the cheeks in a position superficial to the anterior borders of the muscles, subsequent to palpation and prior to exposure of the roentgenographic film, was the procedure used. The bi-lateral images projected on the film were averaged and traced along with dentoskeletal elements including those associated with skeletal type. This line representing the anterior border of the musculature was used to assess muscle position in the vertical …

A Study Of Alveolar Bone Loss And Two-Hour Postprandial Blood Sugar Levels, R. Leslie Arnett

Loma Linda University Electronic Theses, Dissertations & Projects

Two-hour postprandial blood sugar determinations were carried out on 500 patients referred for periodontal care. The mean percentage of alveolar bone loss around the mandibular bicuspid teeth was established for each individual. The subjects were then grouped according to blood sugar levels and the mean alveolar bone loss was calculated. The group was separated into male and female sub-groups and data was computed for these segments as well as the total sample. The data was evaluated in a similar manner for those subjects between 40 and 49 years of age.

No Chi-square determinations were statistically significant but significance in differences …

The Identification Of The Inorganic Components In The Calcareous Corpuscles From Mesocestoides Corti, Larry M. Kegley

Dissertations and Theses

The inorganic components in calcareous corpuscles from Mesocestoides corti have been identified by use of powder x-ray diffraction and emission spectroscopy. Difference methods were compared for the isolation of the calcareous corpuscles from the residual tissue of the Mesocestoides corti. Previously reported and newly developed methods for the isolation are discussed.

Analyses by powder x-ray diffraction for in vivo samples which had been heated at various temperatures ranging from room temperature to 1000°C are reported.

The qualitative emission spectrographic analyses for in vivo and in vitro corpuscles are reported for normal systems and systems designed to study the ion …
