Effects of Three Different Tillage Patterns on Ground and Below-Ground Dwelling Insect Assemblage

Tillage could significantly change the biodiversity in farmlands. As a prominent component of farm-land ecology, crops play a key role in regulating biological communities. To explore the effects of tillage patterns and planting modes, including high-disturbance tillage practices and different plant compositions, on the abundance of soil insects, we tested the responses of soil insects to no-tillage (NT), ridge tillage (RT), and fall plow (FP) treatments with different planting modes. The results illus-trated that planting modes significantly changed the distributions of ground-dwelling insect species and disturbed interactions on the farmland. Soil-dwelling insect assemblages were mainly influ-enced by tillage patterns, which reflected that soil physicochemical properties, especially pH, had the highest contribution to the determination of community composition. The no-tillage system sup-ported the highest predator species richness and lower herbivore richness with higher abundance. In the no-tillage system, most of the insects on the farmland have established relationships, forming IP: 203.8.109.20 On: Fri, 19 May 2023 15:31:03 a relatively high degree of connection between different insects.
