Abstract

Agricultural productivity is frequently threatened by a range of insect pests and pathogens that cause damage to crops. The use of chemical insecticides for control has raised concerns due to negative environmental effects, potential risks to animal and human health, and the emergence of insecticide resistance. Such issues pose threats to the future crop generations. To address these challenges, the application of biological control agents, particularly fungal insect pathogens, has shown promise in effectively managing crop pests and disease vectors. In recent years, significant progress has been made in harnessing the potential of entomopathogenic fungi (EF) for insect pest management. These advancements encompass the discovery and characterization of new fungal isolates, a better understanding their ecological effects in plants, integration of fungal agents within Integrated Pest Management (IPM) strategies, and improvements in their efficacy, formulation, and range of applications. Efforts to overcome limitations in the use of EF under natural conditions and for large-scale applications have also yielded substantial advancements. Here, we provide an overview of recent successes achieved using EF as biocontrol agents, while also addressing their continued limitations, identifying promising areas for further research and challenges associated with utilizing EF. Progress in enhancing the safety and effectiveness of biocontrol methods using EF has led to important breakthroughs. These advancements have the potential to improve food security and safety while reducing adverse environmental impacts associated with pests.
昆虫病原真菌作为害虫管理生物控制剂的潜力和局限性
农业生产率经常受到一系列害虫和病原体的威胁,这些害虫和病原体会对农作物造成损害。由于化学杀虫剂对环境的负面影响、对动物和人类健康的潜在风险以及杀虫剂抗药性的出现,使用化学杀虫剂进行防治已引起人们的关注。这些问题对未来的作物世代构成了威胁。为应对这些挑战,应用生物防治制剂,特别是真菌昆虫病原体,在有效控制作物害虫和病媒方面已显示出前景。近年来,在利用昆虫病原真菌(EF)的潜力进行害虫管理方面取得了重大进展。这些进展包括发现新的真菌分离物并确定其特征,更好地了解其在植物中的生态效应,将真菌制剂纳入虫害综合防治(IPM)战略,以及改进其功效、配方和应用范围。为克服在自然条件下和大规模应用中使用 EF 的局限性所做的努力也取得了重大进展。在此,我们概述了最近将 EF 用作生物控制剂所取得的成功,同时也探讨了其持续存在的局限性,确定了有希望进一步研究的领域以及与使用 EF 相关的挑战。在提高使用 EF 的生物防治方法的安全性和有效性方面取得的进展带来了重要突破。这些进展有可能改善粮食安全和食品安全,同时减少害虫对环境的不利影响。

期刊介绍: Its scope covers all aspects of basic and applied research dealing with insects and more broadly with arthropods inhabiting wild, agricultural and/or urban habitats. The journal also considers research integrating various disciplines and issues within the broad field of entomology and ecology. Entomologia Generalis publishes high quality research articles on advances in knowledge on the ecology and biology of arthropods, as well as on their importance for key ecosystems services, e.g. as biological control and pollination. The journal devotes special attention to contributions providing significant advances (i) on the fundamental knowledge and on sustainable control strategies of arthropod pests (including of stored products) and vectors of diseases, (ii) on the biology and ecology of beneficial arthropods, (iii) on the spread and impact of invasive pests, and (iv) on potential side effects of pest management methods. Entomologia Generalis welcomes review articles on significant developments in the field of entomology. These are usually invited by the editorial board, but proposals may be sent to the Editor-in-Chief for preliminary assessment by the editorial board before formal submission to the journal. The journal also considers comments on papers published in Entomologia Generalis, as well as short notes on topics that are of broader interest.
