Sorghum is a key global crop with substantial economic importance. Implementing green pest management for sorghum is crucial for promoting ecological balance and reducing reliance on chemical pesticides. This study assesses the impact of green pest management on arthropod biodiversity and sorghum yield and quality. Over two years, using Malaise trapping and DNA metabarcoding, we found that green pest management significantly enhanced arthropod diversity, increasing species richness by 5.63% and shifting species composition, notably increasing the abundance of Hymenoptera. Although sorghum yield metrics were higher in the green group compared to the chemical control group, these differences were not statistically significant. However, the green group exhibited improved quality with lower crude fat (3.63% vs. 4.08% in the chemical control group) and higher levels of crude protein (9.18% vs. 9.13%), starch (73.69% vs. 73.41%), and amylopectin (98.53% vs. 98.34%). These findings underscore the benefits of green pest management in fostering biodiversity and enhancing sorghum quality. Future research should focus on optimizing biodiversity-driven agroecosystem resilience and scaling these strategies across diverse agricultural systems.
高粱是一种具有重要经济意义的全球关键作物。对高粱实施绿色害虫管理对于促进生态平衡和减少对化学农药的依赖至关重要。本研究评估了绿色害虫管理对节肢动物生物多样性以及高粱产量和品质的影响。在两年时间里，通过马氏网诱捕和DNA宏条形码分析，我们发现绿色害虫管理显著提高了节肢动物的多样性，物种丰富度增加了5.63%，并改变了物种组成，特别是膜翅目昆虫的数量显著增加。虽然与化学防治组相比，绿色组的高粱产量指标更高，但这些差异在统计学上并不显著。然而，绿色组的品质有所改善，粗脂肪含量更低（化学防治组为4.08%，绿色组为3.63%），粗蛋白、淀粉和支链淀粉含量更高（粗蛋白：绿色组为9.18%，化学防治组为9.13%；淀粉：绿色组为73.69%，化学防治组为73.41%；支链淀粉：绿色组为98.53%，化学防治组为98.34%）。这些发现强调了绿色害虫管理在促进生物多样性和提高高粱品质方面的益处。未来的研究应专注于优化由生物多样性驱动的农业生态系统恢复力，并在不同农业系统中推广这些策略。
