Pharmacological Review Of Chemicals Used For The Capture Of Animals, Peter J. Savarie Mar 1976

Pharmacological Review Of Chemicals Used For The Capture Of Animals, Peter J. Savarie

Vertebrate Pest Conference Proceedings: 7th (1976)

A review of the literature reveals that over 60 chemicals have been used for the capture of wild animals, but only 30 of the most widely used chemicals are discussed in the present paper. For practical considerations these chemicals can be classified as being either (l) neuromuscular blocking agents, or (2) central nervous system (CNS) depressants. Some common neuromuscular blocking agents are d-tubocurarine, gallamine, succiny1choline, and nicotine. M99 and its derivatives, phencyclidine, and xylazine are some of the more commonly used CNS depressants. Neuromuscular blocking agents have a relatively rapid onset and short duration of action but they do not …


Operational Aspects Of Successful Ground Squirrel Control By Aerial Application Of Grain Bait, Conrad Schilling Mar 1976

Operational Aspects Of Successful Ground Squirrel Control By Aerial Application Of Grain Bait, Conrad Schilling

Vertebrate Pest Conference Proceedings: 7th (1976)

By County Ordinance the County Agricultural Commissioner has been charged with rodent suppression in Fresno County, California. For nine years personnel from the Agricultural Commissioner's Office have conducted a county operated and funded program of ground squirrel suppression through the use of aerially applied zinc phosphide treated squirrel oat groats. Planning procedures, relative costs and operational aspects of the program are outlined. This technique of ground squirrel suppression has been shown to have many advantages over hand application of rodent baits. No known hazards to non-target wildlife species have been demonstrated.

Criteria For Rodent Bait Selection, W.R. Smythe Mar 1976

Criteria For Rodent Bait Selection, W.R. Smythe

Vertebrate Pest Conference Proceedings: 7th (1976)

World food shortages become more acute each year, and all too often, rodents are present to take their unwarranted share. To counter this, we must refine our rodent control methods to make them more efficient. To this end, correct bait selection is essential. Grain baits must be selected for purity and acceptability. Grain alterations must be carefully controlled, as well as any additives. Multi-ingredient or composition baits must be checked for size, hardness, protein content and additives. The selection of trap baits is critical for the success of trapping program. In general, fresh coconut is the best bait, but on-site …


Keynote Address—The Role Of Education In Vertebrate Pest Control, Gustav A. Swanson Mar 1976

Keynote Address—The Role Of Education In Vertebrate Pest Control, Gustav A. Swanson

Vertebrate Pest Conference Proceedings: 7th (1976)

Lack of adequate information is emphasized as a major problem in attaining effective control of damage by vertebrate pests, and it is stressed that the problem is widespread in all elements of the public, including those directly involved, like producers and government officials, as well as those only indirectly involved, like the average citizen. A number of specific examples are cited to illustrate the problems of uninformed or inadequately informed publics.


Anticoagulants—A Problem Of Distribution For The Hawaiian Sugar Industry, Allen H. Teshima Mar 1976

Anticoagulants—A Problem Of Distribution For The Hawaiian Sugar Industry, Allen H. Teshima

Vertebrate Pest Conference Proceedings: 7th (1976)

Current rodent control practices for the Hawaiian sugar industry revolve around the use of single grain baits containing anticoagulants in bait stations and zinc phosphide for aerial applications. Neither type of control programs as they are now applied has been very effective against the Norway rat (Rattus norvegicus) which is becoming a major problem species for the industry. As a result, we have sought a more effective anticoagulant, to which the Norway rat is more susceptible, and an improved method of bait distribution. With knowledge of the month-to-month variation in the field rodents' gestation rate, a new control …


The Cost Of Predator Damage Control Using Trapping As The Primary Control Technique, Ronald A. Thompson Mar 1976

The Cost Of Predator Damage Control Using Trapping As The Primary Control Technique, Ronald A. Thompson

Vertebrate Pest Conference Proceedings: 7th (1976)

The justification and economics of the operational animal damage control program in California as conducted by the U.S. Fish and Wildlife Service are discussed. Emphasis is given to the necessity for use of the steel trap. Nearly 83 percent of the depredators are taken by trapping. Annual agricultural losses due to predation were estimated at $4.7 million in California for Fiscal Year 1975. The projected cost-benefit ratio was 1:3.9.


The Use Of Aircraft In Predator Control, Dale A. Wade Mar 1976

The Use Of Aircraft In Predator Control, Dale A. Wade

Vertebrate Pest Conference Proceedings: 7th (1976)

Private aerial hunting of predators for protection of livestock began before 1925 in the western United States. Apparently, it was first used in professional control programs in 1942. Inclement weather, dense vegetation and rough terrain are limiting factors and helicopters are more versatile than fixed-wing aircraft. When it can be employed, aerial hunting is unsurpassed as an immediate control method where livestock losses are severe and the need for control is urgent.

Some Of The Effects Of Domestic Sewage Discharged Into Hickman And Jessamine Creeks In Jessamine County, Kentucky, Henry H. Howell, Mike W. Jones, Robert A. Kuehne

KWRRI Research Reports

A 6-week study was made in the summer of 1971 as an initial effort to determine the extent of pollution that the three sewage disposal plants in Jessamine County, Kentucky, are contributing to its streams. With the rapid population increase in Lexington and nearby municipalities, this study should furnish a basis of comparison for future investigations. Eighteen collecting stations were established in riffle areas of Hickman and Jessamine Creeks, and coliform bacteria, macro-invertebrate populations, fish populations and chemical water quality of each riffle area were studied.

Hickman Creek's flow was augmented by approximately 3,100,000 gallons/day (11,735 -m3/day) from …

1976 Sunflower-Safflower Irrigated Variety Trial 1976-1977, G J. Parlevliet Jan 1976

1976 Sunflower-Safflower Irrigated Variety Trial 1976-1977, G J. Parlevliet

Experimental Summaries - Plant Research

In 1975/76 two varieties of sunflower, Hysun 10 and Hysun 20, as well as Safflower (Gila) were grown in a large alternative crop demonstration. Results were sufficiently good to warrant more and closer examination. This led to the present variety trial using varieties suggested by Mr. M. Poole. The aim was to evaluate six sunflower varieties and one safflower. The work was carried out in the light of reduced profitability of peas, beans and some fruit crops. This results in a number of growers having irrigation water and equipment under-employed. Other farmers are after a crop which will give them …

Studies On Disinfection And Chemical Oxidation With Ozone And Chlorine In Water Reclamation, W. R. Ross, Johannes Van Leeuwen, W. O. K. Grabow Jan 1976

Studies On Disinfection And Chemical Oxidation With Ozone And Chlorine In Water Reclamation, W. R. Ross, Johannes Van Leeuwen, W. O. K. Grabow

Johannes van Leeuwen

Laboratory studies showed that Pseudomonas aeruginosa, Aeromonas hydrophila and Acinetobacter anitratum are more resistant to chlorine and ozone than Escherichia coli. Pseudomonas aeruginosa was the most resistant of all strains tested and was selected as test organism for pilot plant studies on the efficiencies of chlorine and ozone disinfection. The disinfectants proved equally efficient for the disinfection of chlorine demand-free water but ozone was much more efficient in the case of water with a chlorine demand. This difference was confirmed to be due to the property of chlorine to react with nitrogenous substances to form chloramines which are less efficient …
