Abstract

The fall armyworm, Spodoptera frugiperda, has become a significant threat to global agriculture, particularly in sub-Saharan Africa (SSA). Numerous reports indicate substantial insecticide resistance to pyrethroids and organophosphates in S. frugiperda populations. Given the existential and rampant resistance to key conventional insecticides, a new paradigm shift in insecticide resistance management (IRM) of S. frugiperda is urgently needed. This necessitates a critical review of key mechanisms underlying pest biology, ecology, and behavior alongside an evaluation of current insecticide application techniques, pest management practices, and policy frameworks. Notably, the existing literature underscores S. frugiperda's high propensity to develop resistance to various synthetic insecticides. Therefore, an in-depth understanding of the mechanisms underlying resistance is essential for developing sustainable and effective resistance management programs that aligned with the Integrated Pest Management (IPM) scheme. This review discusses the S. frugiperda resistance menace, mechanisms involved, and sustainable management techniques that will assist key stakeholders in making an informed policy formulation to safeguard the pest management subsector and enhance agricultural productivity and food security.

夜蛾抗药性机制、挑战及防治策略综述

秋粘虫（Spodoptera frugiperda）已成为全球农业的重大威胁，特别是在撒哈拉以南非洲地区（SSA）。大量的报告表明，在果叶蝉种群中对拟除虫菊酯和有机磷具有相当大的抗药性。鉴于对主要常规杀虫剂的抗药性存在且十分严重，迫切需要对果蚜进行新的抗药性管理。这需要对害虫生物学、生态学和行为背后的关键机制进行批判性审查，同时对当前的杀虫剂应用技术、害虫管理实践和政策框架进行评估。值得注意的是，现有文献强调了S. frugiperda对各种合成杀虫剂产生抗性的高倾向。因此，深入了解抗性机制对于制定与病虫害综合治理（IPM）计划相一致的可持续和有效的抗性管理计划至关重要。本文讨论了frugiperda的抗性威胁、机制和可持续管理技术，这些将有助于主要利益相关者制定明智的政策，以保护害虫管理分部门，提高农业生产力和粮食安全。

期刊介绍： The Editors of Crop Protection especially welcome papers describing an interdisciplinary approach showing how different control strategies can be integrated into practical pest management programs, covering high and low input agricultural systems worldwide. Crop Protection particularly emphasizes the practical aspects of control in the field and for protected crops, and includes work which may lead in the near future to more effective control. The journal does not duplicate the many existing excellent biological science journals, which deal mainly with the more fundamental aspects of plant pathology, applied zoology and weed science. Crop Protection covers all practical aspects of pest, disease and weed control, including the following topics: -Abiotic damage- Agronomic control methods- Assessment of pest and disease damage- Molecular methods for the detection and assessment of pests and diseases- Biological control- Biorational pesticides- Control of animal pests of world crops- Control of diseases of crop plants caused by microorganisms- Control of weeds and integrated management- Economic considerations- Effects of plant growth regulators- Environmental benefits of reduced pesticide use- Environmental effects of pesticides- Epidemiology of pests and diseases in relation to control- GM Crops, and genetic engineering applications- Importance and control of postharvest crop losses- Integrated control- Interrelationships and compatibility among different control strategies- Invasive species as they relate to implications for crop protection- Pesticide application methods- Pest management- Phytobiomes for pest and disease control- Resistance management- Sampling and monitoring schemes for diseases, nematodes, pests and weeds.
