Abstract

BACKGROUND Crop pests cause substantial crop yield and economic losses, food insecurity, and negative impacts on human health and environment globally. Timely provision of pest risk alerts - that is, the optimum time to intervene against key pests before invasion or establishment - to smallholder farmers on pest management could improve farm performance. However, there is little quantitative evidence testing this hypothesis. RESULTS To address this gap, we use primary survey data from over 4000 smallholder farmers across four African countries: Ghana, Kenya, Malawi, and Zambia. Our results suggest that providing pest alerts to smallholder farmers is associated with a higher probability of adopting integrated pest management (IPM) practices by 8-32 percentage points, as well as an increase in crop yield and income by 18-26%. CONCLUSION Improving timely access to information on pest risks and management could have substantial benefits on farm productivity and income in Africa. Our findings provide a practical pathway on how pest-induced crop losses could be minimized by addressing informational barriers. © 2025 The Author(s).

在非洲，提供虫害警报与改善农场业绩有关。

作物有害生物在全球范围内造成巨大的作物产量和经济损失、粮食不安全以及对人类健康和环境的负面影响。及时向小农提供有害生物风险警报，即在入侵或建立之前对主要有害生物进行干预的最佳时间，可以提高农场绩效。然而，很少有定量证据来检验这一假设。为了解决这一差距，我们使用了来自加纳、肯尼亚、马拉维和赞比亚四个非洲国家4000多名小农的初步调查数据。我们的研究结果表明，向小农提供有害生物警报与采用综合有害生物管理（IPM）做法的可能性增加8-32个百分点相关，并使作物产量和收入增加18-26%。结论改善对有害生物风险和管理信息的及时获取，可大大提高非洲的农业生产力和收入。我们的研究结果为如何通过解决信息障碍将虫害引起的作物损失降至最低提供了一条切实可行的途径。©2025作者。由John Wiley & Sons Ltd代表化学工业协会出版的《害虫管理科学》。
