Abstract:?Agriculture holds a significant strategic position in Yangling.In crop cultivation management, the strategic use of insect natural enemies can effectively reduce the reliance on pesticides and mitigate the potential harm caused by pesticide residues. Among these natural enemies, Coccinellidae and Syrphidae are the most prevalent and valuable guilds preying on many pests including aphids, in the field. However, there was limited knowledge of the species and occurrence of Coccinellidae and Syrphidae due to a lack of systematic monitoring in Yangling farmland. In order to clarify the resources of Coccinellids and Syrphids in Yangling, we monitored these two groups using both Malaise traps and regular surveys in farmland in Yangling, Shaanxi Province from 2018 to 2022. In the past five years, a total of 914 predatory Coccinellids and 1440 Syrphids have been collected. Among Coccinellids, 22 species of Coccinellids were identified, with 16 species and 6 genera. Additionally, there were 14 species of Syrphids, with 12 species and 2 genera identified. The screening and identification of natural enemy insects were conducted by professionals to ensure data quality. This dataset provides basic data on the species, quantity, and occurrence dynamics of predatory Coccinellids and Syrphids. Moreover, it also offers a large number of natural enemy insect specimen photos, ecological photos, Malaise trap photos, specimen bottle photos, and photos of the surrounding environment. It can serve as valuable references for future endeavors aimed at the protection and utilization of predatory insects.
