Abstract　The western corn rootworm (WCR), Diabrotica virgifera virgifera LeConte, is a significant pest affecting maize (Zea mays L.) production, causing substantial economic losses due to root damage and yield reduction. This research examines the impact of various soil insecticides on WCR management and maize yield. Studies have demonstrated that insecticide applications, including pyrethroids, neonicotinoids, and organophosphates, significantly reduce WCR larval density and root damage, leading to increased grain yield. However, the emergence of pyrethroid-resistant WCR populations has compromised the efficacy of some soil-applied insecticides, necessitating integrated pest management (IPM) strategies to mitigate resistance development. Additionally, biological control methods, such as the use of entomopathogenic nematodes and beneficial soil organisms, have shown promise in reducing WCR populations and enhancing maize yield. Crop rotation has also been identified as an effective agronomic practice to manage WCR populations without relying on insecticides, aligning with sustainable agricultural practices. This research underscores the importance of combining chemical, biological, and cultural control methods within an IPM framework to sustainably manage WCR and optimize maize production.
