Abstract:

Objective　To collect data on from previous practices for sustainable rodent control and monitoring of potential rodent infestation. Methods　Rodent and flea control measures were implemented for five consecutive years in urban, rural and wild locations since 2005. Bromadiolone baits were deployed in urban areas and the pests were manually captured, holes blocked, aluminium phosphide applied and isolation belts made up of bromadiolone bait sentinels built in the suburb and field areas. Rodent infestation monitoring Results before, during and after the five-year control period were compared. Results　The rodent density in the urban area dropped to 0.2% in 2009 from 9.0% five years ago, the Rattus norvegicus density to 0 from 20.0%, the flea infestation rate to 0 from 93.3%, and the index of Xenopsylla cheopis to 0 from 16.27. The previously dominant species disappeared including the vector Xe. cheopis. The rodent density hit a record low this year, since the opening of Alataw Pass with a decrease to 3.0% from 6.0% in the rural controlled area. Meanwhile, the Rhombomys opimus density decreased to 2.3/hm² from 9.0/hm² in positive field spots. Conclusion　The current rodent control strategies have effectively eliminated the potential risk of human plague at Alataw Pass. The establishment of a quintuple anti-rodent guard system is discussed for sustainable rodent control and monitoring for potential infestations.
