Suitability Of Reduced Pressure Center-Pivots, John E. Gilley

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Selection criteria for reduced pressure center-pivot irrigation systems are developed. An analysis of the combined effects of the application rate characteristics or center-pivot irrigation systems and the Soil Conservation Service (SCS) soil intake family curves is used to determine the maximum depth of water which could be applied per irrigation for various types of soils and sprinkler packages. These irrigation depths are used to determine guidelines for proper selection of reduced pressure center-pivot systems. The results can be used as a general guide to determine if a particular system may have a runoff problem under a given situation.

Ultrastructure Of The Interface Between Stages Of Eimeria Funduli (Apicomplexa) And Hepatocytes Of The Longnose Killifish, Fundulus Similis, William E. Hawkins, John W. Fournie, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The interface between stages of Eimeria funduli and hepatocytes of the experimentally infected killifish Fundulus similis was studied ultrastructurally. Parasitophorous vacuoles (PV's) in which meronts, macrogamonts, and microgamonts developed were lined by an inner, smooth membrane and an outer, ribosome-studded membrane. The outer membrane bordered on the cytoplasm of the host cell, whereas the inner one limited the PV. The origins of these membranes have not been determined with certainty, but images were observed in which both membranes appeared to be continuous with the outer nuclear membrane of the host cell. Furthermore, the outer PV membrane was continuous with membranes …

Bioassay Of Solubilized Bacillus Thuringiensis Var. Israelensis Crystals By Attachment To Latex Beads, Danny J. Schnell, Mary Ann Pfannenstiel, Kenneth W. Nickerson

Papers in Microbiology

Solubilized crystals of Bacillus thuringiensis var. israelensis were 7,000 times less toxic to Aedes aegypti larvae than intact crystals, presumably because mosquito larvae are filter feeders and selectively concentrate particles while excluding water and soluble molecules. A procedure is described whereby soluble toxins are adsorbed to 0.8- micrometer latex beads, with retention of toxicity. The latex bead assay should make it possible to analyze the structure and mode of action of the mosquito toxin.

Bird Damage Chronology And Feeding Behavior In Two Sunflower Fields, Sacramento, California, 1982, Michael L. Avery, Richard Dehaven

Vertebrate Pest Conference Proceedings: 11th (1984)

Bird damage was assessed weekly from soon after anthesis until harvest in two sunflower fields in the Sacramento Valley, California, during 1982. Damage chronology was similar at both sites, with damage concentrated in the second to fourth weeks after anthesis when the seeds were in the doughy stage of development. Less than 10% of the total losses caused by birds occurred during the final month before harvest. Overall bird damage was quite low (0.20 and 0.26%) in each field and in one, damage by wind was 2.4 times greater than that caused by birds. Brewer's blackbirds (Euphagus cyanocephalus) …

Biological Rationale For 1080 As A Predacide, Walter E. Howard, Robert H. Schmidt

Vertebrate Pest Conference Proceedings: 11th (1984)

Compound 1080 (sodium monofluoroacetate) is a uniquely selective predacide for controlling coyotes, compared to other predacides. In addition to discussing the biological aspects of 1080, the reasons for the current emotional-political status of 1080 are also reviewed because the biological rationale concerning 1080 has been largely determined by a conspiracy orchestrated in 1972 by an individual of the Council on Environmental Quality but assisted by others from the U.S. Department of the Interior and the Environmental Protection Agency. Many of the distortions about 1080 can also be traced to environmental organizations which still use 1080 as an issue which they …

Gull Exclusion, George W.J. Laidlaw, Hans Blokpoel, Victor E.F. Solman, Margaret Mclaren

Vertebrate Pest Conference Proceedings: 11th (1984)

This paper reports on work carried out in a variety of sites and installations that have required active gull control. The methods used are a result of observations by a variety of researchers and attest to the effectiveness of a behavioral control technique with the use of thin steel spring wire or monofilament fishing line.

Research On Winter Roosting Blackbirds And Starlings In The Southeastern United States, Donald F. Mott

Vertebrate Pest Conference Proceedings: 11th (1984)

Each winter, more than 300 million blackbirds and starlings congregate in hundreds of roosting sites in the southeastern United States. In addition to nuisance problems involving odor and property damage from fecal material, and potential airport hazards, research studies to date suggest that the major problems with these birds and their roosts involve grain losses in feedlots, latent disease transmission to livestock, and public health concerns with histoplasmosis. Control methods development studies have shown the utility of Starlicide and nonchemical control methods in reducing starling feedlot problems. A sprinkler-irrigation delivery system for the surfactant, PA-14, has been developed that enhances …

Efficacy Of A Number Of Toxic Baits And Batting Against The Voles, Microtus Agrestis And Arvicola Terrestris , Marvo Myllymaki

Vertebrate Pest Conference Proceedings: 11th (1984)

The results from two series of control experiments against the voles, Microtus agrestis and Arvicola terrestris, are reported. In a series of field experiments in the 1970s, three acute toxicants (zinc phosphide, crimidine and difluorpropanol) were tested against Microtus. Difluorpropanol (Gliftor) was found to be the most effective, but no ready-made bait containing it was available. The performance of the crimidine bait (Kastrix) was good enough to fulfill the registration requirements, while the zinc phosphide bait (Myrax) failed to give acceptable results. In the second series (early 1980s) a brodi-facoum bait (Klerat) was found to be as efficacious …

Toxic Characteristics Of Fluorocitrate, The Toxic Metabolite Of Compound 1080 , Peter J. Savarie

Vertebrate Pest Conference Proceedings: 11th (1984)

This paper reviews toxicological research involving fluorocitrate, the toxic metabolite of sodium monofluoroacetate (fluoroacetate), which is the active ingredient in the pesticide Compound 1080. Many toxicological studies have been done with fluoroacetate and the results obtained are actually due to the fluorocitrate because it has been definitely proved that, from a biochemical perspective, fluoroacetate is not toxic but fluorocitrate is. The classical explanation of the toxic action of fluorocitrate is that it inhibits the enzyme aconitase in the tricarboxylic acid cycle. Deactivation of aconitase results in decreased energy production by cells and ultimately death of the organism. However, the more …

The Use Of Wild Carnivore Serology In Determining Patterns Of Plague Activity In Rodents In California, Charles R. Smith, Bernard C. Nelson, Allan M. Barnes

Vertebrate Pest Conference Proceedings: 11th (1984)

Carnivores obtain plague infection through ingestion of infected rodents or rabbits or via flea bite. Most are resistant to infection, show little or no symptoms, and produce antibodies to Yersinia pestis which may persist for several months. Consequently, carnivores can be used as serological plague sentinels using the specific passive or indirect hemagglutination test in the laboratory. A carnivore serology program for plague detection began in California in 1974. The program is a cooperative effort incorporating state and federal vector-borne disease units and state and federal predator animal control personnel. The program has proven to be an important tool in …

Aldehyde Volatiles For Use As Coyote Attractants, Jerry H. Scrivner, Walter E. Howard, Roy Teranishi

Vertebrate Pest Conference Proceedings: 11th (1984)

This study was designed to evaluate the attractiveness of eight aldehyde volatiles (octanal, nonanal, decanal, undecanal, dodecanal, tridecanal, tetradecanal, and hexadecanal) found in sheep liver extract and coyote (Canis latrans) estrous urine to determine their potential for use as odor attractants in predator control. The odors were presented to captive coyotes at the Hopland Field Station and the length of time coyotes responded to the odors was recorded. Octanal, nonanal, decanal, and undecanal all elicited as much sniffing and rub-rolling as did a known coyote attractant, trimethylammo-nium decanoate (TMAD). Generally male and female coyotes were equally attracted to …

A New Concept In Pocket Gopher Control, Allen D. Tunberg, Walter E. Howard, Rex E. Marsh

Vertebrate Pest Conference Proceedings: 11th (1984)

A new concept in pocket gopher control is advanced which relies on two behavioral traits common to pocket gophers: 1) gophers are quick to invade unoccupied burrow systems when the previous occupant has been killed by a rodenticide; and 2) the invading animal will use existing food stores (i.e., baits) left by the previous gopher. With long-lasting (i.e., durable) baits containing sufficient toxicant, several pocket gophers can be controlled by a single baiting. This new approach assists in improving gopher control, for control is extended beyond the initial baiting results. Pocket gophers missed in the original treatment or gophers invading …

The White-Eyes Eradication Effort In California, Valerie Van Way

Vertebrate Pest Conference Proceedings: 11th (1984)

Upon discovery in 1980 in the San Diego area of a feral population of Indian White-eyes (Zosterops palpebrosa palpebrosa), a prohibited species in California, an eradication program was begun by the California Department of Food and Agriculture (CDFA). Mist-netting and shooting proved to be the most successful of the capture methods explored. After three and one-half seasons of retrieval effort and 330 birds taken, fewer than a dozen birds now have been detected in the wild. Within the remainder of the fiscal year, CDFA is conducting intense survey and retrieval. Whether eradication is feasible and applicable to other …

History And Status Of Predator Control In Texas, Dale A. Wade, Donald W. Hawthorne, Gary L. Nunley, Milton Caroline

Vertebrate Pest Conference Proceedings: 11th (1984)

A historical review of predatory animal damage and the development of the Texas animal damage control (ADC) program is provided, including a discussion of predator species, methods of control and limitations caused by laws, regulations and policies. Recommendations are made for improvements to permit a more comprehensive program with adequate funding, personnel and control methods.

The Effects Of Mowing On The Rodent Community Of A Native Tall Grass Prairie In Eastern Nebraska, Cliff A. Lemen, Mary K. Clausen

University of Nebraska State Museum: Mammalogy Papers

Our results indicate that mowing, like burning, greatly reduces the use of an area by Microtus and increases the density of Peromyscus maniculatus until the grass can grow back. Depending on the rate of growth of the grass this process can take more than a year. If the prairie is mowed every year to maximize the production of hay, populations of Microtus cannot be maintained at high densities.

The study site, Nine Mile Prairie, is one of the few natural tallgrass prairies remaining in eastern Nebraska. It covers about 240 acres and is located 5 km north and 9 km …

Predator Management For Ducks On Waterfowl Production Areas In The Northern Plains, Alan B. Sargeant, Phillip M. Arnold

Vertebrate Pest Conference Proceedings: 11th (1984)

In 1961, Congress initiated the Accelerated Wetland Acquisition Program, which has resulted in purchase of about 2,450 scattered small Waterfowl Production Area (WPA) management units in the Prairie Pothole Region of Minnesota, Montana, North Dakota, and South Dakota. The WPAs are administered by the U.S. Fish and Wildlife Service (FWS); increased duck production is a major management objective. Duck recruitment rates in much of the four-state area are very low because of high predation, especially on nests. Principal predators responsible for the predation are six mammalian carnivores and one rodent. The actions of predators on WPAs, especially in central and …

Acute Rodenticides In The Control Of Rodent Pests In China: A Review, Zuwang Wang

Vertebrate Pest Conference Proceedings: 11th (1984)

In China, the earliest record, "The Book of Song," vividly describes that farmers complained of rodent damage and earnestly hoped rodents did not eat their crops. It will be seen from this that since the spring and autumn period (770-476 B.C.), rats, mice and voles have been among the major problems of China. It is said that there are 400 species of mammals in China and 150 species of them are rodents, of which 25-30 species of rodents are usually considered serious pests. Large amounts of grassland, forests and agricultural crops are destroyed or seriously damaged every year. There is …

Multiple Trait Evaluation Of Bulls For Calving Ease, L. Dale Van Vleck, K. M. Edlin

Department of Animal Science: Faculty Publications

Evaluation of bulls for calving difficulty of their calves by a multiple trait, mixed model procedure seems appropriate for a number of reasons. Average calving ease scores and their variances and heritabilities differ according to sex of calf and parity of mother. The multiple trait procedure automatically accounts for differences in averages, variances, and heritabilities. The procedure also allows for the magnitude of herd-year-season effects to be different for four traits as defined by calving difficulty scores when measured on: male birth by a heifer, female birth by a heifer, male birth by a cow, and female birth by a …

Prevalence Of Extreme Detergent Resistance Among The Enterobacteriaceae, Vance Kramer, Kenneth Nickerson, Nancy V. Hamlett, Caroline O'Hara

Kenneth Nickerson Papers

The detergent-resistance properties of 208 independent isolates of the Enterobacteriaceae have been examined. Of these bacterial strains, 200 were able to grow in the presence of ≥5% sodium dodecyl sulfate, including all members of the Klebsielleae tribe. This resistance does not appear to be plasmid encoded. It is proposed that detergent-resistant organisms he termed saponotolerant or saponophilic, by analogy with other microorganisms occupying harsh ecological niches. In contrast to their prevalent resistance to anionic detergents, not one of the 208 strains tested was found to grow in the presence of three different cationic detergents. This sensitivity to cationic detergents may …
