Vampire Bat Control: A Review And Proposed Research Programme For Latin America, Arthur M. Greenhall

Vertebrate Pest Conference Proceedings: 4th (1970)

In Latin America paralytic rabies transmitted by vampire bats is a major cause of death in cattle. This problem becomes more acute as countries attempt to increase livestock production to feed rapidly expanding human populations. Vaccination has been the principal weapon against rabies, however this offers no protection to domestic animals and poultry against daily predation of vampire bats. Established methods of vampire bat control, though limited, have proved effective and should be continued while more effective methods are being developed and tested. Existing methods are discussed in some detail. Of the approximately 200 kinds of bats found in Latin …

PROCEEDINGS: FOURTH VERTEBRATE PEST CCONFERENCE held at El Rancho Hotel, West Sacramento, California, March 3, 4 and 5, 1970. Edited By Richard H. Dana, Conference Chairman. Sponsored by the California Vertebrate Pest Committee

Opening Remarks - Fourth Vertebrate Pest Conference, Richard H. Dana

Vertebrate Pest Conference Proceedings: 4th (1970)

I am pleased to welcome you to the Fourth Vertebrate Pest Conference. This is our second Sacramento meeting. The first was in 1962 - eight years ago. It was an historic occasion. It was the first conference devoted exclusively to vertebrate pests. This conference is sponsored by the California Vertebrate Pest Committee comprised of representatives from the California Department of Agriculture, the University of California at Davis, Department of Animal Physiology and the Agricultural Extension Service; the U. S. Bureau of Sport Fisheries and Wildlife, Division of Wildlife Services and of Wildlife Research, the California Departments of Public Health, Fish …

Keynote Address --- "The Year Of Ecology", Robert I. Cushing

Vertebrate Pest Conference Proceedings: 4th (1970)

It seems to me that there are at least two things we should be concerned about. First, I believe there is a real possibility that the environmental quality bandwagon will get to playing so loud and to rolling so fast that there can be some unfavorable consequences in food production and processing-—the job I work at and that some of you work at. Second, I believe there are signs that we could lose our balance—-that we could be making decisions on emotional instead of rational grounds. Reason seems to be in danger from an epidemic of emotion. And we need …

Outlook For Rodenticides And Avicides Registration, James O. Lee

Vertebrate Pest Conference Proceedings: 4th (1970)

The history of pesticide regulations is presented. Major emphasis is on federal regulations. The evaluation of avicides and rodenticides is discussed and related to regu¬lations. Currently registered avicides and rodenticides are described along with a listing of efficacy criteria requirements. The future of registration of avicides and rodenticides is projected.

New Factors Controlling Populations Of Land Vertebrates In Great Britain, N. W. Moore

Vertebrate Pest Conference Proceedings: 4th (1970)

The vertebrate fauna of Britain is impoverished by nature. Further, virtually the whole land surface has been altered radically by Man, and all vertebrate species have been profoundly affected both unconsciously and consciously by Man. The rate of change during the last quarter of a century has been far greater than at any other time; new deleterious factors - increased habitat destruction, increased human pressure and motor traffic, myxomatosis and a vast increase in pesticide use have coincided in this period. The public's attitude to several common species (e.g., rabbit, woodpigeon, fox and birds of prey) has been equivocal and …

The Pharmacology Of Rodenticides, S. A. Peoples

Vertebrate Pest Conference Proceedings: 4th (1970)

The compounds used as rodenticides are tremendously varied in their chemical structure and mechanism of action. With a few exceptions, these agents are generally poisonous to all animals, including man, and a great deal of study has been directed to their toxicity in animals other than rodents. However, the development of new compounds as Norbormide and certain antifertility drugs which are highly selective in their action may justify the hope that the ideal rodenticide free of secondary toxic hazards will soon be available. Until this happy announcement is made, a review of the pharmacology of the older compounds is in …

Importance Of Wildlife Rabies Control, Richard L. Parker

Vertebrate Pest Conference Proceedings: 4th (1970)

ABSTRACT: Rabies in animals has been known in North America for over two centuries, and whether the disease was initially present in wild species or was introduced by dogs, it has been known in skunks for almost a century and a half. Today more rabies cases in wild animals are reported than in domestic animals, and a considerable proportion of both human and domestic animal exposures to the disease are the result of wild-animal contact. The most useful techniques for controlling wild animal rabies today are methods that reduce contact between infected individuals and susceptible individuals; these involve the manipulation …

Stress-Induced Angular Momentum Quenching In Mgo: Fe2+ As Observed By Mössbauer Spectroscopy, J. Chappert, A. Misetich, Richard B. Frankel, N. A. Blum

Physics

Under the influence of a suitable uniaxial stress, the quenching of the electronic angular momentum of the low-lying threefold degenerate Γ_5g level of Fe²⁺ in cubic MgO has been observed by Mössbauer spectroscopy. The result is consistent with Ham's model for the appearance of a quadrupole doublet at low temperatures. A value for the strain coefficient of Fe²⁺ in MgO has been obtained: G₁₁=585 cm^-1.

A Permanent Type Poison Station For Porcupine Control, William A. Neitro

Vertebrate Pest Conference Proceedings: 4th (1970)

A method has been devised to protect the poison strychnine-salt blocks used in controlling porcupines, Erethizon dorsatum, from the weather, killing of non-target animals and vandalism. An aluminum poison bait station has been developed which is light weight, durable, camouflaged, and safe. These structures are easily constructed and are relatively inexpensive when longevity is considered. Porcupines are controlled effectively and economically using this method

Trapping - The Oldest Profession, William D. Fitzwater

Vertebrate Pest Conference Proceedings: 4th (1970)

While trapping is probably the oldest pursuit of man, predating hunting and agriculture, it has not undergone many drastic changes since the first primitive attempts. An arbitrary classification of traps [improvised traps, snares-and nets, cage traps, spring traps and glues] is discussed and examples of each group given. As the behavioral and physical characteristics of vertebrate animals vary so much, it is impossible to discuss trapping procedures in any detail, but certain principles apply to most situations. These are: (1) need for an understanding of the target species' habit patterns, (2) selection of a trap size and design suitable for …

Studies In Microencapsulation Of Rodenticides, P. B. Cornwell

Vertebrate Pest Conference Proceedings: 4th (1970)

Warfarin, zinc phosphide, norbormide and alphachloralose have been microencapsulated by the technique of coacervation and fed to laboratory rats (R. norvegicus) and mice (M. musculus). Results are given of experiments in which the concentration of rodenticide, wall material and phase ratio have been varied separately and in combination. Experiments are also reported in which normal and encapsulated rodenticide has been fed together in the same test diet.

Chemosterilants As An Approach To Rodent Control, Rex E. Marsh, Walter E. Howard

Vertebrate Pest Conference Proceedings: 4th (1970)

Capitalizing on research directed toward oral contraceptives for humans, a wide variety of compounds are now under study for their practical value in inhibiting rodent reproduction to suppress detrimental populations. This paper discusses the specifications of ideal rodent chemosterilants and the advantages of chemosterilants over other methods of control, and compares the potential values of chemosterilants acting on females, males, and both sexes. Specific situations are detailed where chemosterilants will be most valuable in rodent control, together with proposed methods of application. Chemosterilants are not expected to become a panacea for control, but since they are based on sound biological …

A Vehicle Mounted Bait Dispenser, Richard E. Griffith Jr., James Evans

Vertebrate Pest Conference Proceedings: 4th (1970)

A 3-inch-diameter plastic tube mounted on a truck was designed for distributing bait (cut carrots or grain) for mammal control. Baits are fed into the tube by an operator standing in the truck bed. The device is light-weight and detachable and permits rapid, accurate placement of bait along a line on the ground or in a plowed furrow.

Pocket Gopher Problems And Control Practices On National Forest Lands In The Pacific Northwest Region, Paul R. Canutt

Vertebrate Pest Conference Proceedings: 4th (1970)

Pocket gophers of concern to foresters in the Pacific Northwest belong to the genus Thomomys (13). The two species believed responsible for most conifer damage are the northern pocket gopher (T. talpoides) which occurs east of the Cascade mountains in Washington, Oregon, and south into the northeastern edge of California and the nearly identical Mazama pocket gopher (j_. mazama), which ranges throughout western Oregon and into north central California (13). Pocket gopher damage is best known to agriculturalists who for many years have suffered losses to root, hay, fruit, and bulb crops, as well as damage to irrigation canals (23). …
