Abstract: The investigation on the soil insect larvae in agricultural and forest lands in mid-west plain of Jilin Province showed that the species number and in dividuals quantity of soil insect larvae were significantly higher in mid plain than in west plain, and the difference in individuals quantity mainly manifested in the communities of Carabidae, Tipulidae, and Corylophidae. The species number and individuals quantity of soil insect larvae in farmland and residential area were obviously higher than those in protection forest land. Cultivation made soil insect larvae distribute more evenly in soil profile, and differences were observed in the responses of Coleoptera, Diptera and Lepidoptera larvae to different land use patterns.
