Mongolian Rangelands: Rodent Problems And Approaches To Alleviate Damage, Dale L. Nolte
Proceedings of the Seventeenth Vertebrate Pest Conference 1996
Rodents are a major constraint to forage production for livestock in Mongolia. A technical program to identify the magnitude of the problem and strengthen the research capabilities of Mongolian rodent specialists was initiated in 1994. The Brandt's vole is the most widespread and the most detrimental rodent to the steppes of Mongolia. Limited resources inhibit activities by the Mongolian Plant Protection Service to reduce rodent populations. Alternative means to monitor vole activity were developed. Laboratory and field trials showed that voles were susceptible to zinc phosphide treatment and indicated how bait acceptance could be improved.

Zinc Phosphide Residues In Voles: Scenarios Showing Low Risks To Domestic Cats And Dogs, Ray T. Sterner
Proceedings of the Seventeenth Vertebrate Pest Conference 1996
Zinc phosphide (Zn3P2, CAS #1314-84-7) is an acute rodenticide having numerous agricultural applications. This paper estimates the risk of mortality posed to domestic cats (Felis domesticus) and dogs (Canis familiaris) from ingestion of voles (Microtus spp.) that succumb to 2.0% Zn3P2 baits. Following a brief review of direct/indirect studies and incident reports relevant to nontarget-Zn3P2 effects and vole control, four scenarios of volecarcass ingestions needed for light and heavy cat and dog predators/scavengers to receive approximate lethal doses (ALDs = 40 mg/kg) of undigested rodenticide …

Investigations And Management Of Epizootic Plague At Ice House Reservoir, Eldorado National Forest, California, 1994 And 1995, Kenneth R. Townzen, Malcolm A. Thompson, Charles R. Smith
Proceedings of the Seventeenth Vertebrate Pest Conference 1996
The occurrence of plague (Yersinia pestic) at Ice House Reservoir in 1994 and 1995 was characteristic of widespread epizootics in high use recreational areas of California. Staff of the Vector-Borne Disease Section investigated these epizootics and found dense populations of plague susceptible California ground squirrels (Spermophilus beecheyi) with high numbers of fleas, primarily Diamanus montanus, the most important plague vector. This combination indicated a high risk of plague exposure to campground users. A non-fatal human case of plague, contracted at Mountain Camp II, was reported after the initial epizootic investigation. The patient's exposure occurred prior …
