Success In Rat Control In Kuwait, K.S. Al-Sanei, T.M. Zaghloul, A.M. Salit, M.T. Omar, M.M. Balba

Vertebrate Pest Conference Proceedings: 11th (1984)

The preliminary rat survey prior to the actual attack phase of Rat Control Program in Kuwait revealed an infestation rate with the Norway rat, Rattus norveqicus, in buildings ranging between 32.7% and 70.7%. The comparatively high infestation was observed in 92.5% of Kuwait buildings. Moreover the infestation reached 99% in certain districts of the country. This high infestation was associated with an increase in rat-borne diseases particularly murine typhus, salmonellosis, rat-bite fever and certain parasitic diseases.

A programme for rodent control in Kuwait was initiated through a political decision by the cabinet which gave the full responsibility of rodent …

Hazards To Golden-Mantled Ground Squirrels And Associated Secondary Hazard Potential From Strychnine For Forest Secondary Pocket Gophers, R. Michael Anthony, Gerald D. Lindsey, James Evans

Vertebrate Pest Conference Proceedings: 11th (1984)

Radio telemetry and capture-recapture techniques were used to evaluate the hazards to golden-mantled ground squirrels ( Spermophilus lateralis) from hand baiting with 0.5% strychnine-treated for western pocket gophers (Thomomys mazama) on conifer plantations in eastern Oregon. Toxicology data were collected on field-killed and caged ground squirrels and on caged mink (Mustela vison, great horned owls (Bubo virginianus), and red-tailed hawks (Buteo jamaicensis). Ground squirrel populations were reduced 50% to 75% following underground baiting for pocket gophers. Maximum amount of strychnine found in cheek pouches and carcass of a field-killed golden-mantled ground …

Commingling Of Norway And Roof Rats With Native Rodents, Rex O. Baker

Vertebrate Pest Conference Proceedings: 11th (1984)

The ecology of plague relies on the intermixing (commingling) of animal hosts and their ectoparasites. There has been a noticeable increase in commingling of rats and ground squirrels in Southern California in recent years. This paper discusses this phenomenon in Los Angeles and Orange Counties, where it occurs, how it results from man's activities, and the ecology of varying locations. The role of fleas as vectors of plague and the intermixing of fleas between hosts are discussed. Action to reduce the incidence of commingling and the threat of plague to the urban society is addressed.

Efficacy Of Three Anticoagulant Rodenticides For The Control Of Poison-Shy Rattus Rattus, Devendra Bhardwaj, Ishwar Prakash

Vertebrate Pest Conference Proceedings: 11th (1984)

House rats (Rattus rattus) which do not consume a lethal dose of zinc phosphide develop poison-shyness after a single exposure. The surviving poison-shy rats cannot be baited again with zinc phosphide for about three months. Poison-shy rats were separately given anticoagulant baits (brodifa-coum 0.005%, coumatetralyl and warfarin 0.025%) in no-choice tests. The first two anticoagulants were found to be the most efficient ones. It was observed that those R. rattus which had consumed 56.7 mg/kg or more zinc phosphide died sooner (P < 0.05 to 0.1) after anticoagulant poisoning when compared with normal rats. It is conjectured that prothrombin inhibition is accelerated in the liver of poison-shy R. rattus due to the action of phosphine present in the earlier ingested sublethal dose of …

Preliminary Investigations Of The Effectiveness Of Trimethacarb As A Bird Repellent In Developing Countries, R.L. Bruggers, P. Sultana, J.E. Brooks, L.A. Fiedler, M. Rimpel, S. Manikowski, N. Shivanarayan, N. Santhaiah, I. Okuno

Vertebrate Pest Conference Proceedings: 11th (1984)

Preliminary information on the effectiveness of trimethacarb as a bird repellent on broadcast seed and ripening crops was obtained during 1982 and 1983 from studies in Haiti, India, the Philippines, Bangladesh, Mali, and the United States. R50 and LD50 determinations for nine pest bird species to cereal crops in these countries indicated birds were not as sensitive to trimethacarb as to the avian repellent methiocarb. Rice and millet seed germination was not inhibited at 0.125 and 0.25% treatment levels. Wheat seed germinated well at treatments of ≤0.5% in Bangladesh. Sorghum seed did not germinate as well at any treatment level. …

Repellent Or Aversive Chemicals In Sheep Neck Collars Did Not Deter Coyote Attacks, Richard J. Burns, Guy E. Connolly, Richard E. Griffiths Jr.

Vertebrate Pest Conference Proceedings: 11th (1984)

Since 1974 the Fish and Wildlife Service has studied a "toxic collar" to poison coyotes that attack collared sheep and goats. The collar patent (McBride 1974) indicates that the same collar could deliver chemicals to repel coyotes, thus saving both the coyote and the livestock.

This report summarizes our experience with nonlethal tests of collars. During collar tests with 10 different toxicants, 21 coyotes received sublethal doses followed by aversive behavior or potentially aversive reactions. The subsequent predation history of these coyotes was examined for prey-avoidance. After a sublethal test, all coyotes killed lambs or kids in about 40 days, …

Vole Control In Field Crops, Jerry P. Clark

Vertebrate Pest Conference Proceedings: 11th (1984)

There are five species of meadow voles found in California. The two that are most economically important are Microtus californicus and Microtus montanus. Meadow vole populations are extremely cyclic, reaching a peak every four to six years. During these periods when the vole population is increasing in numbers, damage to crops like alfalfa, artichokes, potatoes, and sugar beets can occur. The best time to survey for vole activity is before the crop is planted. The grower or farm operator should look for vole activity in grassy borders around the crop or along roadsides and ditch bank areas. Snap-trapping may …

Performance Of Sodium Cyanide Ejectors, Guy Connnolly, Gary D. Simmons

Vertebrate Pest Conference Proceedings: 11th (1984)

Performance of three models of sodium cyanide (NaCN) ejectors was evaluated at Port O'Connor, Texas, early in 1982. M-44s, M-50s, and coyote getters were test-pulled and reset at 7-day or 21-day intervals for 42 days. Each pull was recorded as good if, in our judgment, it would have taken a coyote. Based on 402 to 430 test pulls of each ejector model, the percentages of good pulls were 40% for M-50s, 73% for M-44s, and 99% for coyote getters. M-44s with shortened plungers performed better than standard M-44s.

Most pulls of M-50s resulted in ejection failure due to corrosion between …

Nuisance Bats: Current Technology In Their Management And Control, Robert L. Corrigan

Vertebrate Pest Conference Proceedings: 11th (1984)

Managing nuisance bat colonies can be accomplished via exclusion (bat-proofing) or in limited cases via the use of repellents. Exclusion is emphasized as the first and most desirable approach providing it is also practical. New products and devices have recently become available which may significantly aid in making exclusion programs more possible and practical. Repellents such as lights, fiberglass batting and various improvised mechanical devices may all have some utilization. Controlling nuisance bats can be accomplished via the use of toxicants and trapping, although there is considerable opposition from many bat researchers towards the use of toxicants. Toxicants that have …

Woodpeckers: A Serious Suburban Problem?, Scott R. Craven

Vertebrate Pest Conference Proceedings: 11th (1984)

Damage to homes and buildings caused by woodpeckers is a widespread and locally severe problem in vertebrate pest control. This paper describes the distribution, characteristics, and impacts of woodpecker damage as determined by questionnaires, interviews, and published accounts. Woodpecker damage results from territorial behavior, feeding, or nesting activity. Some plywood and cedar are especially vulnerable. Average loss per incident is about $300, although some cases result in much greater losses. Disturbance and aggravation are also important factors. Abatement measures include scare devices, structural modification, chemical treatment of the siding, and shooting or trapping (with a permit). Success is variable. Recommendations …

Keynote Address—Politics Of Pesticides, David H. Dietz

Vertebrate Pest Conference Proceedings: 11th (1984)

The politics of pesticides is a rather humorless topic, as I'm sure most of you know. I've always been told that when you start an address or make a speech you ought to have some kind of humor, if for no other reason that you at least get your audience to listen to you for two minutes during any presen-tation. For those of you that may be members of the Audubon Society or members of the Sierra Club, I'll, in advance, make my apologies for the joke I'm about to tell. It's not really meant as a put down if …

Rat Control In Alberta, Michael J. Dorrance

Vertebrate Pest Conference Proceedings: 11th (1984)

A rat control program, administered and coordinated by Alberta Department of Agriculture, has kept Alberta essentially free of Norway rats (Rattus norvegicus) since 1950. A control zone, 29 x 600 km, along the eastern border prevents rats from moving into Alberta from the east. Sporadic rat infestations within the interior of Alberta are reported by concerned citizens and eradicated by government personnel. Strong support for the program by citizens and local governments was developed through public education and information. The program has been successful for a variety of reasons including geography, climate, legislation, availability of warfarin, the relatively …

Opening Remarks—Eleventh Vertebrate Pest Conference, Dell O'Clark

Vertebrate Pest Conference Proceedings: 11th (1984)

On behalf of the Vertebrate Pest Council, it is my pleasure to welcome all of you to Sacramento and to the 11th Vertebrate Pest Conference. The first Vertebrate Pest Conference was held 22 years ago here in Sacramento in 1962. The conference is now over two years into its third decade of existence. In all this time, the basic goals of the Conference have not changed; that is, to provide a basis for dissemination of information on vertebrate pests and their control. Some things have changed in these 22 years, most of which have been for the good. The first …

Wetlands Forest Communities As Indicators Of Flooding Potential In Backwater Areas Of River Bottomlands, Edward E. Dale Jr.

Arkansas Water Resources Center Technical Reports

A phytosociological study was made of forest types that occur in backwater and river bottomlands of the Gulf Coastal Plain, Arkansas Valley, and Mississippi Delta Regions of Arkansas. Twenty different forest types dominated principally by a single species were identified and described. Their occurrence was then correlated with flooding conditions in their habitats and the types were arranged along decreasing moisture gradients. Those forest types tolerant of flooding or saturated soils between three months to a year or more are Taxodium distichum, Nyssa aquatica, Cephalanthus occidentalis, Salix nigra, and Planera aquatica types. Those tolerant from one to three months are …

Use Of Microcomputers To Aid Wastewater Treatment Plant Operations, David G. Parker, Sandra C. Parker

Arkansas Water Resources Center Technical Reports

This report presents the development of a microcomputer based data management system for wastewater treatment plants. The relational database model was shown to be well suited for data management applications in wastewater treatment plants. A general data management system was developed for use with a microcomputer using a commercially available relational database management system. Use of the developed system requires no special computer training. The system was tailored for use at the wastewater treatment plant at Springdale, Arkansas. The capabilities of the system were demonstrated with actual data from the Springdale plant.

Water Management Simulator Presentations, Leslie E. Mack

Arkansas Water Resources Center Technical Reports

One of the larger stumbling blocks to comprehensive water management is the lack of public understanding of the multitude of variables that operate at the same time within the hydrologic cycle. With more public understanding, there is greater public support for various water projects. Dr. John R. Amend from Montana State University developed a water management simulator which could handle a large number of variables simultaneously of natural surface and groundwater flow plus a number of water use variables on an accelerated time sequence. By using several remote control devices, participants can "control" their water use but have no control …

Evaluation Of Nitrogen And Phosphorus Enrichment Using In Situ Enclosure Bags With Temporal Indigenous Phytoplankton Populations, Richard L. Meyer, W. Reed Green

Arkansas Water Resources Center Technical Reports

An in situ experimental procedure and protocol was developed to evaluate nitrate and phosphate enrichment using isolated indigenous phytoplankton assemblages during different seasons. Results of the comparison of the parameters-temperature, pH, alkalinity, conductivity, and dissolved oxygen between the open water and enclosed systems indicated that there was no significant influence of the physicochemical factors on the isolated biological processes. Growth responses were measured by turbidity, biomass and chlorophyll-a, the most sensitive being chlorophyll-a. Additions of nitrate and phosphate were added in known concentrations and in different magnitudes of concentration based upon ambient conditions and ratio. During the fall, phosphorus influenced …

Groundwater Quality And Mineral Deposits Relationships In The Ozark Mountains, Kenneth F. Steele

Arkansas Water Resources Center Technical Reports

Ninety-nine groundwater sites were sampled in northern Arkansas in order to determine the effect of local manganese, phosphate, pyrite, lead-zinc and uranium mineralization on the groundwater chemistry. Most of this study (75 springs) was concentrated in the Batesville manganese district. Hydrogeochemical exploration for these types of manganese deposits appears possible with 44 percent of the springs within 2000 feet of mineralization having anomalous metal concentrations (especially manganese). Because only a few springs were sampled in the remaining areas, the results are not conclusive; however, only the pyrite and small lead-zinc deposit would appear worthy of additional investigation. None of the …

Studies Of Effectiveness Of Commercial Home Treatment Systems, William W. Trigg, Raymond D. Couser

Arkansas Water Resources Center Technical Reports

Eleven home water systems were tested representing six different types of filtering systems. Tests were made for Sulfates, Nitrates, Phosphate, Iron and Escherichia coli and Enterobacter aerogenes before and after passing through a home treatment system. All of the systems removed iron adequately but had little effect on the removal of nitrates, phosphates, sulfates or control of pH. Since none of the ground waters was contaminated by coli- forms, nothing was established regarding the effectiveness of bacterial removal by these systems.

Factors Affecting The Removal Of Suspended And Dissolved Solids In High Strength Wastewater From Vegetable Processing, William A. Sistrunk

Arkansas Water Resources Center Technical Reports

Fifty or more individual factorial experiments were designed to study the effectiveness of physical-chemical and micro-biological treatments in removal of suspended and dissolved solids in effluent from potatoes, hominy, dry beans and other vegetables. The wastewaters were obtained from local processing plants and treated with 3 to 5 inorganic salts, 13 polymers, and 3 or more pH levels during 12 months. Also, selected strains of yeast and fungi were used to assimilate the effluent. Individual inorganic salts were more effective on a certain vegetable effluent than others. Polymers (anionic and cationic) were more effective in coagulating suspended solids in combination …

Wetlands And Coal Surface Mining: A Management Handbook, Milady A. Cardamone, Jan R. Taylor, William J. Mitsch

KWRRI Research Reports

As the third phase of a three-year project, this report outlines management options for protecting wetlands during the surface mining of coal, particularly for the portion of the Eastern Interior Coal Region that is found in Kentucky, Indiana, and Illinois. It is presented in manual form for use by coal mine operators, regulatory agencies and research institutions.

The previous phases of the project produced an atlas of the most heavily-mined areas of the western Kentucky coal field, which classified and identified wetlands in these areas, and discussed some specific impacts of mining on these wetlands. The need to present information …

A Statistical Comparison Of A Direct Filtration And A Conventional Water Treatment Facility In The Intermountain Region, Susan K. Burns, V. Dean Adams

Reports

Interest in low-cost direct filtration facilities and their effectiveness in treating the potable water sources of the Intermountain Region is increasing as the need for treated water supplies increase. Direct filtration is a water treatment scheme which does not include sedimentation and in some cases flocculation. Compared to conventional treatment, direct filtration has lowered capital costs, reduced space requirement, and decreased sludge quantities. Moreover, the direct filtration process may offer large reductions in coagulant dosages and costs.

Currently information comparing a direct filtration system to a conventional water treatment system in the Intermountain area is not readily available. The specific …

Evalution Of Drainage Tile To Alleviate Salt Building In Heavy Soils Irrigated With Brackish Water And Cropped With Rice And Soybeans, T. C. Keisling, J. T. Gilmour, H. D. Scott, A. M. Sadeghi, R. E. Baser

Arkansas Water Resources Center Technical Reports

The use of tile drains for alleviating soluble salt accumulation on silt loam soil was investigated during 1984. Although the chemical analyses of the floodwater and tile drainage water were very similar suggesting that the floodwater was moving to the tile drain, the overall results so far indicate that this is not a feasible solution owing to lack of significant drainage. Application of DRAINMOD utilizing soil and weather data from Arkansas showed no significant effluent from the tile drains for our experimental site during rice production. This was attributed to the extremely slow saturated hydraulic conductivity values for this particular …

Precedings Of Arkansas Lakes Symposium Limnological Studies Of Lake Chicot, Arkansas, Joe F. Nix, Frank R. Schiebe

Arkansas Water Resources Center Technical Reports

Lake Chicot is an oxbow lake that was created more than 600 years ago by the meandering of the Mississippi River. It is located in Chicot county in southeastern Arkansas adjacent to the present Mississippi River. As the largest natural lake in Arkansas it earned an early reputation for its good fishing and recreational value. Development of a levee system forced the enlargement of the lakes watershed to its present 350 square miles. Initially this alteration affected only the volume flow through the lake, drastically reducing the water residence time. Because the watershed was located in one of the most …
