Abstract：
[Objectives] To clarify the structure and diversity of insect communities in peanut fields in Laixi, Shandong province. [Methods] The insect community structure of peanut fields was investigated using malaise trapping from June 2014 to June 2015. [Results] A total of 89 967 insects from 13 orders and 117 families were collected throughout the year. The main orders were the Hymenoptera, Coleoptera, Diptera, Lepidoptera and Hemiptera, and the dominant families in each order were the Braconidae (Hymenoptera), Nitidulidae (Coleoptera), Lauxaniidae (Diptera), Noctuidae (Lepidoptera) and Aphididae (Hemiptera). [Conclusion] The results of diversity analysis show that diversity, evenness, and richness, indices were consistently high in peanut fields. These results indicate that the insect community structure in Laixi peanut fields has high stability.
