Responses Of The Adc Program To A Changing American Society, Bobby R. Acord

Vertebrate Pest Conference Proceedings: 15th (1992)

Changes in the Animal Damage Control (ADC) program are reviewed relative to changes in American societal background and attitudes. Many of the program changes that occurred in the past were imposed on ADC in response to external factors, while more recent program changes have been and will continue to be more self-directed. Examples of ADC's proactive approach to dealing with critical issues are provided.

Field Evaluation Of Three Anticoagulant Rodenticides Against Mus Musculus Populations In Apartmental Buildings In New York City, Ranjan Advani

Vertebrate Pest Conference Proceedings: 15th (1992)

Field efficacy studies using three anticoagulant rodenticides were conducted on House mice, Mus musculus under a variety of conditions in 35 apartment buildings scattered over four boroughs of New York metropolitan area. Percent control successes and relative efficacies of various rodenticides and their formulations were determined by recording pre and post control census for about four years.

After four monthly treatments, the control success rate of bromadialone (0.005%, meal form) was highest (94.5%) followed by brodifacoum (0.005%, pellet form, 91.23%) and diphacinone (77.72%) in the wax cake formulation. However, build up of the residual mice population was faster in the …

Efficacy Of Methyl Anthranilate As A Bird Repellent On Cherries, Blueberries And Grapes, Leonard R. Askham

Vertebrate Pest Conference Proceedings: 15th (1992)

Anthranilitic acid derivatives, used as common food additives, have been explored as bird repellent agents for a number of years. Research in this study show that methyl anthranilate, when exposed to the UV spectrum of sunlight, readily dissipates within 64 hours. The addition of surfactants and extenders did not appreciably alter the degradation curve, nor did they lessen the phytotoxic properties of the chemical.

Field trials under IR-4 guidance and support indicate that methyl anthranilate (MA) is an effective, biodegradable, nontoxic bird repellent. In formulation with a lipid molecular binding compound degradation of methyl anthranilate was extended from four to …

Exposure Of Persons To Phosphine Gas From Aluminum Phosphide Application To Rodent Burrows, Rex O. Baker

Vertebrate Pest Conference Proceedings: 15th (1992)

An industrial hygiene study was performed monitoring levels of phosphine gas workers are exposed to when applying aluminum phosphide tablets to rodent burrows. Clothing and gloves were monitored for phosphine gas from residual dust. Air in the breathing zone was monitored with short and long term monitoring equipment. No levels of phosphine exceeding the legal permissible exposure limits (PEL) was detected and although residues were detected on clothing, the levels were usually quite low and dissipated in open air to undetectable levels within 12 to 17 hours in all but a few cases. Hand application was also compared to a …

Cougar Attacks On Humans: An Update And Some Further Reflections, Paul Beier

Vertebrate Pest Conference Proceedings: 15th (1992)

I examined historical records of unprovoked attacks by cougars on humans in the U.S. and Canada during 101 years (1890-1990). There were 9 attacks resulting in 10 human deaths and at least 44 nonfatal attacks. In a recent paper, I listed these attacks and discussed them in considerable detail (Beier 1991). Although extremely rare, attacks on humans have increased markedly in the last 2 decades, during which cougar numbers and human use of cougar habitats have increased. There is no substantial evidence that habituation underlies this increase in attacks. The data provide weak support for the notion that an attacking …

The Most Dangerous Pest: "Homo Environmentals", Robert James Bidinotto

Vertebrate Pest Conference Proceedings: 15th (1992)

I speak of that insatiable predator, Homo environmentalus. This predator is a subspecies of homo sapiens, of which I observe several examples present. For the past several years, under special funding by Reader's Digest, I have made a special study of this pest, also known by his more familiar name of "environmentalist activist."

Problems With Management Of A Native Predator On A Threatened Species: Raven Predation On Desert Tortoises, William I. Boarman

Vertebrate Pest Conference Proceedings: 15th (1992)

Common ravens (Corvus corax) are a major predator on the threatened desert tortoise (Gopherus [=Xerobates] agassizii). Large numbers of juvenile tortoise shells have been found beneath known raven nests and perches; many shells that show evidence consistent with raven predation have been found sporadically throughout the range of the tortoise; significant proportional decreases in juvenile size/age class distributions have been identified; and people have observed ravens killing, carrying, and consuming juveniles. In 1988 the U. S. Bureau of Land Management initiated a process to evaluate, design, and implement a program to reduce raven predation …

Review Of Research On Control Of Bird Pests In Australia, Mary Bomford

Vertebrate Pest Conference Proceedings: 15th (1992)

The most significant damage inflicted by birds in Australia is to germinating cereal and to ripening sunflower and fruit crops. The main pests are several native psittacine and corvid species, silvereyes (Zosterops lateralis) and European starlings (Sturnus vulgaris). The economic cost of damage is largely unquantified. While losses to industries as a whole are often low, losses to individual growers may be severe, and losses are distributed patchily in space and time. Shooting is the most widely practiced and most ineffective bird control technique used in Australia. Despite the high numbers of birds killed, damage persists, …

A Role For Fertility Control Wildlife Management In Australia?, Mary Bomford, Peter O'Brien

Vertebrate Pest Conference Proceedings: 15th (1992)

Increasing community awareness of the moral and animal welfare issues associated with conventional pest animal control has focused interest on non-lethal alternatives, such as fertility control. In Australia, animal welfare organizations have proposed fertility control as a solution to pest problems with feral horses and kangaroos. Wildlife damage control achieved by non-lethal, non-toxic and humane means would have wide appeal and application. Importantly, assessments of effectiveness must focus on damage control, rather than fertility control, per se. Most tests of fertility control drugs and techniques examine effects on reproduction, rather than on population dynamics. Many tests and models have not …

Opening Remarks—Fifteenth Vertebrate Pest Conference, John E. Borrecco

Vertebrate Pest Conference Proceedings: 15th (1992)

Good morning. On behalf of the Vertebrate Pest Council, it is my pleasure to welcome you to the 15th Vertebrate Pest Conference. I am John Borrecco and I have the honor of representing the Council as Chair for this Conference. This meeting marks the 30-year anniversary of the Conference.

That purpose is to provide you the best, up-to-date information on vertebrate pest problems and solutions to those problems. Our objectives, quite simply, are to promote the exchange of …

Rodent Control In The Conservation Of Endangered Species, A.P. Buckle, M.G.P. Fenn

Vertebrate Pest Conference Proceedings: 15th (1992)

The commensal rodent pest species have spread from their ancestral homes in Asia to inhabit many natural ecosystems worldwide. The introduction of these exotics has often had a significant effect on endemic plant and animal species but their impact has, perhaps, been most severe on off-shore and oceanic islands where nesting birds, insects, terrestrial molluscs, reptiles and amphibians are all vulnerable. Conservationists have used a variety of control approaches either to reduce or eliminate the pressure of competition and predation exerted by introduced rodents on island populations of endangered species. Successful projects have involved a sequence of carefully-planned operations. Firstly, …

Toxicity Of Compound 1080 To Magpies And The Relationship Of Dose Rates To Residues Recovered, Richard J. Burns, Guy E. Connolly

Vertebrate Pest Conference Proceedings: 15th (1992)

The acute oral LD₅₀ of Compound 1080 to magpies was estimated at 1.78 mg/kg indoors, 1.91 mg/kg outdoors in summer, and 2.30 mg/kg outdoors in winter. Postmortem 1080 residues were detected in 75 of 76 treated birds. Higher doses yielded higher 1080 residues. Within dose levels, birds surviving longer carried lower residues. In a separate test, an average residue of 0.09 ppm was found in 8 birds treated at 1.59 mg/kg and euthanized 24 h post dosing. The adjusted dietary LC₅₀ of Compound 1080 to magpies tested indoors was estimated at 16 ppm. During LC₅₀ tests, the …

Developing A Strategy Of Predator Control For The Protection Of The California Least Tern: A Case History, Peter H. Butchko, Maynard A. Small

Vertebrate Pest Conference Proceedings: 15th (1992)

In recent years, predation has been determined to be a seriously limiting factor in the reproduction of the endangered California least tern (Sterna antillarum browni) at many of its nesting colonies. Among them is a major colony at Camp Pendleton Marine Corps Base near Oceanside, CA. Early efforts to control predation were limited in effectiveness. In 1988, the U.S. Department of Agriculture, Animal Damage Control Program was contracted to provide control of mammalian and avian predators. The development of the successful strategy that has evolved over four years is discussed, with emphasis on the development and application of …

Field Efficacy Evaluation Of Diphacinone Paraffin Bait Blocks And Strychnine Oat Groats For Control Of Forest Pocket Gophers (Thomomys Spp.), D.L. Campbell, J.P. Farley, P.L. Hegdal, R.M. Engeman, H.W. Krupa

Vertebrate Pest Conference Proceedings: 15th (1992)

The effectiveness of bait and the effectiveness of operational baiting were both evaluated for controlling forest pocket gophers (Thomomys spp. ) with strychnine oat groat bait and diphacinone paraffin block bait. Radio-telemetry monitoring and recovery of pocket gophers showed that control of individual pocket gophers 1 month after baiting was 72% for strychnine bait and 62% for diphacinone bait. Reduction in pocket gopher activity from operational baiting was based on censusing activity in sample plots. After 1 month the reduction in activity was 61% for strychnine oats and 36% for diphacinone blocks. Bait blocks implanted with radio transmitters were …
