Abstract: The population ecology of Tetraonchus monenteron was investigated by analyzing the field-collected samples. The results show that the prevalence and infection intensity were different from different host groups with different body lengths, the mean prevalence was 45.4%, the mean infection intensity was 11.8±6.05, the prevalence was decreased but the infection intensity was increased with the increase of host body length; the mean abundance and the variance-mean ratio of Tetraonchus monenteron in the host Esox lucius Linnaeus were increased at first and then decreased with the increase of host body length, and the variance-mean ratio was higher than 1 in all the host groups with different body lengths, the over-dispersion of parasite population in host population was observed, and the degree of the aggregation increases with the increase of mean abundance.
