[The yearly dynamics relationship between burrow track flea index and population of Citellus dauricus]
Acta Entomologica Sinica 41 (4), 396-400
Abstract: According to the fluctuation of population of Citellus dauricus and its burrow track flea index in Wuningbatu Sumu, Zhengxiangbai Banner, Inner Mongolia Autonomous Region during 1981~1993, the authors have found that there are nine flea species with Citellophilus tesquorum mongolicus (66.0%) as the most dominant member, and Frontopsylla luculenta (25.0%) the second. Neopsylla abagaitui and N. bidentatiformis are only of common occurrence whereas the other species are rather scare. The correlation between the burrow host population and its burrow track flea index is significant (P<0.03), i. e., burrow track flea index=0.2491+0.0596 host population. But the correlation between the burrow track flea index and its infecting flea rate is not significant (0.05<P<0.10) , and the diversity and evenness of flea species are influenced significantly by the proportion of C. t. mongolicus in the flea population. Furthermore, the relationship between the burrow track flea index and body flea index is significant (P< 0. 05), i.e. burrow track flea index=0.2709+0.0504 body flea index, and that between the burrow track flea index and burrow nest flea index is also significant (P<0. 07), i.e., burrow track flea index=0.2765 + 0.0035 burrow nest flea index. Finally, the correlation among the three kinds of flea index is approximately as follows: (burrow nest flea index) : (body flea index) : (burrow track flea index) =100:10:1.
