Landscape heterogeneity can enhance biodiversity, but its impacts are rarely disaggregated over time. Thus, off-season effects on ecosystem service providers, service delivery and underlying (ecological) determinants often remain occluded. We assessed how landscape structure affects predator biodiversity in subtropical rice systems during winter. Furthermore, we investigated the impact of resident predator populations on the adult abundance of the overwintering generation rice stem borer Chilo suppressalis. To study these dynamics, 32,396 insect predators belonging to 52 species (19 families) were systematically surveyed in 19 fallow rice fields over a span of three years. Landscape composition and configuration jointly defined overwintering predator diversity, with the former exhibiting the strongest impacts. Rice fields with winter crop cover embedded in complex landscapes harbored the most diverse predator populations. Field size and forest proximity increased abundance and richness ..., , # Data from: Landscape composition shapes biological control by promoting off-season predator diversity

## Description
The dataset contains 3 documents
1. \"`landscape_data.csv`\" is the landscape information of each study site; each of the column refers to the following:
* Site: Study site
* Scale(m): radius of landscape sector (500m and 1000m radii)
* Dis_Forest: shortest distance of the center of each field to the edge of forest habitat
* MFS (ha): The average area of all patches in the landscape type (mean field size)
* SNH: propor...,
