Efficacy Testing Of Vertebrate Pest Control Agents, Paul Ochs

Vertebrate Pest Conference Proceedings: 5th (1972)

Justification for efficacy testing is provided under the present FIFRA, and the PR notice 70-15 requirements. In addition, the Pure Food and Drug Laws, the Delaney Amend-ment and other laws effect the requirements of registration of all economic poisons. Basic preliminary registration information such as toxicological data, chemistry data, must be provided on all chemicals proposed as economic poisons. Once the basic chemical and toxi-cological properties have been determined, the applicant must consider basic efficacy requirements. Efficacy requirements should consider the effects of particle size and shape, taste and odor, impurities, diluents, stickers and solvents, volatility, mode of action, and …

The Problem Of Anticoagulant Rodenticide Resistance In The United States, William B. Jackson, Dale E. Kaukeinen

Vertebrate Pest Conference Proceedings: 5th (1972)

Resistance of commensal rodents to anticoagulant rodenticides is not a new phenomenon. Its confirmed presence in several areas of northern Europe is wel1-documented (Jackson 1969, 1972; Bentley 1969; Lund 1969). Not until 1971 was a similar situation with the Norway rat (Rattus norvegicus) to be demonstrated in the United States (Jackson et al. 1971). Because it represents an initial occurrence, the site and background observations will be described in some detail. The rural area involved around Cleveland School in Johnson County is 25 miles SE of Raleigh, N. C. and about five miles in diameter (fig. 1). The typical farm …

House Mouse Behavior And Its Significance To Control, W. D. Klimstra

Vertebrate Pest Conference Proceedings: 5th (1972)

It seems explicitly evident that animal control practices must now, and especially in the future, emphasize fuller appreciation of the habits of each kind of animal. Further, this will require consideration be given to behavioral aspects as expressed by a population as a whole of a given species, as well as each individual animal within that population. Animals react with one another and with all characteristics of their environment; and, this in turn results in an identifiable reaction or behavior of each population as a unit of social organization. Although within broad limits some aspects of these responses, whether individual …

The Influence Of Attractants And Repellents On The Feeding Behaviour Of Rattus Norvegicus, J. O. Bull

Vertebrate Pest Conference Proceedings: 5th (1972)

Poison baits are extensively used for commensal rodent control; considerable folk lore exists regarding the use of additives to induce rodents to come to and eat poison baits. This paper describes a rational evaluation of attractants and the influence of different odours in inducing Rattus norvegicus to feed at given locations. The influence of certain repellents was also examined. Tests consisted of attempts to induce rats to feed at non-preferred sites or to repel them from preferred sites. Place preference was the dominant factor in feeding by rats, and odours failed to influence feeding activity significantly.

Rat Reduction With Indigenous Methods, P. J. Deoras

Vertebrate Pest Conference Proceedings: 5th (1972)

Mujumdar (1968) has recorded that there are 566,000 villages in India as compared to 2699 towns, and that there is 322,460,000 acres of cultivable land and probably 500 million domestic rats in India. The food production target in 1968 in India was to be 110 million tons. National rodent committee 1967 mentioned of a loss of one million ton of food grains by rats alone. Deoras (1968) has mentioned that 3 common rats in Bombay were consuming 26 gm. of food grains per day, that is, about one ounce, while the quantum of cereal rations available per man in some …

Carbon And Nitrogen As Regulators Of Algal Growth In Treated Sewage, Edward G. Foree, Charles Reece Scroggin

KWRRI Research Reports

Continuous flow algal cultures were grown under three different growth conditions using secondary sewage treatment plant effluent as the growth medium. The only variable within each run was the hydraulic residence time. The concentrations of growth regulating nutrients were varied between the runs so comparisons of the algal mass, composition, nutrient uptake, and genera could be made. The importance of CO₂ availability for algal growth was also studied. A kinetic theory which based algal growth on cellular nutrient concentration was verified. The second phase of the study was a batch culture study in which the same growth medium was …

Opening Remarks - Fifth Vertebrate Pest Conference, Rex E. Marsh

Vertebrate Pest Conference Proceedings: 5th (1972)

It is a pleasure to welcome you to the Fifth Vertebrate Pest Conference. It has been 10 years since the first Conference was held in Sacramento in February of 1962. The attendance has grown at each successive conference and, from the looks of the audience this morning, we shall surpass all previous records. It would, however, be wrong to judge the significance of this conference on attendance alone, for we are equally or more concerned with the quality of the conference and its ultimate contribution to the specialized area of wildlife management. The Conference is sponsored by the California Vertebrate …

Keynote Address - Vertebrates: A Resource Needing Management, Donald A. Spencer

Vertebrate Pest Conference Proceedings: 5th (1972)

A veritable storm of concern for wildlife - approaching biotechnology - is currently sweeping the nation. Some of this concern has a sound basis. But the very best of ideas and programs can be carried so far that they become irrational. We appear to be driving head-on into irrational actions with respect to environmental good housekeeping. The vegetative cover in the United States has changed markedly as the result of Man's occupancy, reducing the habitat on which some wildlife species depend and greatly enhancing that of others. Competition, a no-holds-barred struggle, continues unabated between all living things for the finite …

The Extending Of Cotton Rat Range In California - Their Life History And Control, Dell O. Clark

Vertebrate Pest Conference Proceedings: 5th (1972)

Cotton Rats (Sigmodon hispidus eremicus Mearns) are known to have reached the Imperial Valley in 1921 from the Colorado River along canal banks. Recently (1967-69) cotton rats were found distributed throughout the irrigated portion of the Imperial Valley, Imperial County, California. Limited crop damage has occurred and is described. Life history information is included. Control measures are listed.

Related Laws On Exotic And Native Wild Animals, Donald F. Stork

Vertebrate Pest Conference Proceedings: 5th (1972)

This paper is submitted in an effort to acquaint the personnel of allied State agencies with related laws which control the public and private possession of live exotic and native wild animals. The need for this common knowledge of related laws by agencies with law enforcement responsibility is readily apparent when the annual number and related problems from imported or resident wild animals in California are examined. In addition to resident wild animal populations, millions of fish and thousands of mammals, birds, and reptiles enter California each year through the utilization of most methods of transportation. Most of these imported …

Catechol Effected Dissolution Of Silicate Minerals, James Maurice Kelley

Dissertations and Theses

The chemical properties of guanidinium tris(catecholato)siliconate, [(H₂N)₂C=NH₂]₂[Si(C₆H₄O₂)₃]·XH₂O (0 < X < 1), precipitated from an ammoniacal solution of silica and catechol by adding guanidinium hydrochloride, (H₂N)₂C=NH·HC1, were studied, and infrared, nmr, x-ray powder diffraction, and analytical data were gathered.

This same compound was, upon addition of' (H₂N)₂C=NH·HC1, isolated from 0.25, M aqueous catechol solutions buffered at pH 10 and containing the silicate minerals albite, andradite, muscovite, pyrophyllite, talc, and wollastonite, and also from unbuffered catechol solutions containing wollastonite and andradite.

It is concluded from this work that the formation of an anionic catechol-silicon complex, Si(C₆H₄O₂)₃²⁻, is largely responsible for the dissolution of the minerals mentioned above. From this conclusion, it is proposed that naturally occurring members of the class of organic compounds to which catechol belongs, the aromatic v̲i̲̲c̲-diols, may play …

Obstacles To Economic Progress In Ethiopia's Red Sea Coast And Gulf Of Aden, Abraham Alemayehu

Marine Affairs Theses and Major Papers

Ethiopia is a coastal state whose overall economic progress has been and still is being affected by a number of coastal and related obstacles. This paper will attempt to discuss each and every one of these obstacles and other relevant aspects in order to justify as much as possible Ethiopia's lack of progress in economic development. By no means these are not the only obstacles responsible for affecting the country's entire economic progress. The obstacles that I would like to present here are only those which are more or less directly related to maritime, geographical and geopolitical problems on the …

Fisheries Report No 11 - The Fauna, Flora And Planned Usage Of The Dampier Archipelago, A. A. Burbidge, R. I. T. Prince

Fisheries Research Reports

The Dampier Archipelago is a group of islands off the north west coast of Australia (20 20! - 20 45'S, 116 Cast . 117°E), first discovered by William Dampier in 1699 and subsequently named after him by the Baudin expedition of 1801. This name has since been applied by some authors to include all islands from Roebourne to North West Cape, including both Barrow Island and the Monte Bello Islands, but it is more correctly applied to those islands within a 30 mile radius of the town of Dampier.

Ir. recent times, three parties have visited the Archipelago and examined …

Fisheries Report No. 10 - An Investigation Into The Status Of Introduced Trout (Salmo Spp.) In Western Australia, Dr N. M. Morrissy

Fisheries Research Reports

Both brown (Salmo trutta L.) and rainbow (S. gairdnerii trout Richardson) have been introduced into inland waters of the south-west of Western Australia to provide an amateur sport fishery on a gamefish. The large indigenous marron (Cherax tenuimanus Smith) is present in most of these waters. The only large native fish present is the cobbler (Tand- anus bostocki Whitley) which, while highly edible like the marron, has no game-fish qualities.

Hatchery production of trout for stocking waters has been centred at Pemberton in the lower south-west since 1931 when Mr. Cyril Glew, acting in a private capacity, succeeded in hatching …
