The Pocket Gopher As A Pest In Mexico, Desley Whisson, Beatriz Villa-C
Proceedings of the Seventeenth Vertebrate Pest Conference 1996
Pocket gophers of the genus Orthogeomys and Pappogeomys are major pests in rangeland and agricultural areas throughout Mexico. Control relies on the indiscriminate use of fumigants and poison baits. These controls are applied in a haphazard manner; do not provide long-term benefits and the non-target hazards and public safety risks are perceived to be extremely high. Studies indicate that as a result of reinvasion of treated areas or territory expansion of animals surviving the control procedure, controls relying on removal of animals may be limited unless applied at frequent (every three months or less) intervals.

Proceedings of the Seventeenth Vertebrate Pest Conference 1996
Between 1988 and 1995 populations of rats on agricultural premises were sampled to investigate the distribution of anticoagulant-resistant rats in England and Wales. In total, approximately 1,670 rats from 115 locations were tested for resistance to warfarin. Rats that were warfarin-resistant were subsequently tested for resistance to difenacoum, and since 1991 for resistance to bromadiolone. In some cases rats were also tested for resistance to brodifacoum, and in 1995 for resistance to flocoumafen. The results of these tests showed that there was a high prevalence of resistance to the first-generation anticoagulant, warfarin, in several regions of England and Wales. Rats …
