Abstract:Objective  To understand the community structure and dynamics of nest fleas and provide supports for inhibiting plague spread. Methods  Fleas were collected and identified from the nest of Microtus fuscus in Sichuan foci from May to September of 2011 and 2012, and the flea infected rate, flea index, community structure and dynamics were investigated. Results  A total of 87 nests were digged, and collected, and 3715 fleas belonged to 8 species were identified, in which Callopsylla sparsilis and Amphipsylla tuta tuta were the dominant species. The flea infected rate was 100%. The flea index and dominant fleas index were monthly different (P<0.05). Nest flea index and dominant flea index in 2011 was significantly higher than that in 2012 (P<0.05). No significantly different of index diversity and dominance index was observed (P>0.05). Evenness index in 2011 was significantly lower than that in 2012 (t=-3.796, P<0.05) with monthly different (ANOVA: F=2.692, P<0.05), and it reached the lowest value in September of 2011 (0.712). Conclusion  Flea infected rate and flea index of the nest of Microtus fuscus were high in Sichuan Foci. The dominant species were Callopsylla sparsilis and Amphipsylla tuta. The flea index and dominant species index in 2012 were significantly lower than that in 2011. The evenness index and species richness were significantly different among years and months.
