Status, biology, impact, and management strategies of Phyllotreta striolata (Fabricius) (Coleoptera: Chrysomelidae): a comprehensive review of biocontrol strategies

Abstract

Abstract Background Phyllotreta striolata (F.) (Coleoptera: Chrysomelidae) is a major pest of cruciferous crops worldwide, with high resistance to chemical insecticides, resulting in severe economic losses. Conventional chemical control measures have limited efficacy, highlighting the urgent need for sustainable biocontrol strategies. Results This review evaluates various biocontrol strategies, including fungal and bacterial pathogens, nematodes, pheromone-based control methods, and emerging technologies such as RNA interference (RNAi) and gene cloning. While these approaches show potential in laboratory and field trials, their effectiveness is constrained by factors such as environmental adaptability, cost, and pest resistance. Additionally, this review highlights the crucial role of integrated pest management (IPM) in the sustainable control of P. striolata. Conclusion This review underscores the necessity of optimizing biocontrol strategies and suggests that integrating biocontrol, genetic technologies, and IPM could offer a more effective and sustainable solution for P. striolata management. Future research should focus on enhancing the stability and scalability of these technologies to promote environmentally friendly pest control.
