[Objectives]  Understanding the ecological effects of regional landscape composition on the natural predators of maize pests during the maize seedling stage could provide a theoretical basis for the ecological control of pests in maize field. [Methods]  Research was conducted at 92 sample points in corn fields in Shandong province. Based on population dynamics, remote sensing imaging and land cover classification data, we used a mixed effects model to analyze the effects of cropland, residential industrial traffic, grassland, forest and water, on predator populations during the maize seedling. [Results]  A total number of 3 744 predatory species were identified, of which the most abundant were Erigonidium graminicolum (55.29%), Propylaea japonica (25.32%), Orius similis (6.73%), Theridion octomaculatum (4.01%), Harmonia axyridis (3.58%) and Misumenops tricuspidatus (3.47%). Forest and water habitat had a significant positive effect on the abundance of Propylaea japonica, and grassland and water habitat had a significant positive effect on the abundance of Misumenops tricuspidatus. Water and forest habitat had a significant positive effect on the overall number of predatory species. [Conclusion] Non-crop habitat plays a crucial role in maintaining populations of the natural predators of maize pests during the maize seedling stage in the north China farmland landscape.
