This study evaluated the parasitism capacity of three Trichogramma species (T. ostriniae, T. chilonis, and T. dendrolimi) on corn borer eggs under laboratory conditions and monitored corn borer dynamics in the Huang-Huai-Hai region (2015–2022). The laboratory results showed Trichogramma ostriniae had the greatest parasitism ability. Field experiments showed T. ostriniae achieved the highest parasitism rates (up to 90%) during peak pest periods (mid-July and mid-August), nearly double that of the chemical controls. Significant reductions in corn damage were observed in 2016 and 2021 in T. ostriniae treated fields, which also showed higher natural enemy diversity, abundance, and species evenness compared to chemical control areas. Trichogramma ostriniae provides comparable pest control efficacy to chemicals while enhancing ecological sustainability, making it a viable strategy for integrated pest management.
