Community Structure of Chigger Mites Parasitic on Small Rodents and Insectivores in Shandong Province

Living rodents and insectivores were captured with rodent taps, the chigger mites out their bodies were numbered and identified to study the community structure of chigger mites from Shandong Province. A total 6 species of chigger mites were collected from 5 species of rodents and insectivores. The results show that Leptotrombidium scutellare parasitic on 4 species of hosts. Parasitic rate and the index of Walchia pacific on Cricetulus triton is the highest (72 73%, 52 00). L.linhuaikongense, L.palpale, L.taishanicum are commonly observed on Apodemus agrarius, C.triton. The diversity indexes of the communities of chigger mites on A.agrarius and C.triton is relatively higher, and the similar index between the two communities is the highest among the rodents. The diversity index of chigger mite's community on A.agrarius changes with the season. The community structure of chigger mites parasitic on various rodents is different, and changes with season.
