Currently, the Modular Phage-based Symbiont Target system has reached Technology Readiness Level (TRL) 4\u20135, with robust validation in controlled laboratory settings and preliminary demonstration in relevant operational environments (field trials). However, advancing the MPST platform to higher TRL stages necessitates addressing several critical challenges: (i) preventing the rapid emergence of phage resistance in host symbiotic bacteria; (ii) further reducing the production and application costs of the nano-biopesticide formulation; (iii) consistently improving control efficacy under complex and variable field conditions; (iv) systematically evaluating potential off-target effects on nontarget organisms and broader ecosystem impacts; and (v) establishing a high-throughput phage library encompassing diverse phage collections against major pest\u2013symbiont pairs.<\/strong><\/span><\/p>\n\n\n

Resolution of these challenges will depend on future multisite field trials conducted in outbreak areas of\u00a0Spodoptera frugiperda<\/em>, collaborative process optimization with biopesticide enterprises, and integration with national phage resource-sharing initiatives. From a policy standpoint, the MPST platform demonstrates strong alignment with the United Nation\u2019s Food and Agriculture Organization\u2019s global initiative for chemical pesticide reduction.<\/p>\n\n\n\n

Highlights<\/h3>\n\n\n\n

Spodoptera frugiperda<\/em>, a major global pest, is resistant to several chemical insecticides via gut symbiont detoxification metabolism. This reduces the effectiveness of traditional control and increases insecticide residues and ecological risks, thereby threatening sustainable agriculture.<\/p>\n\n\n\n

Phage SP-1 (a newly isolated phage strain deposited at the China Center for Type Culture Collection (CCTCC) under accession number CCTCC M 20241620) targets and lyses the symbiont Enterococcus casseliflavus<\/em> that mediates detoxification metabolism of insecticides, thereby restoring sensitivity to chlorantraniliprole.<\/p>\n\n\n\n

Zein-based nano-insecticide co-encapsulates SP-1 and chlorantraniliprole, withstands 60\u00b0C heat and UV.<\/p>\n\n\n\n

Compared with free chlorantraniliprole, the nano-insecticide improves Spodoptera frugiperda<\/em> control by 17%, reduces soil residues by 82.4%, and is safe for the environmental microbial community and maize.<\/p>\n\n\n\n

The Modular Phage-based Symbiont Targeting platform enables flexible component swapping, offering a sustainable solution for resistant pests.<\/p>\n\n\n\n

The Modular Phage-based Symbiont Targeting system targets gut symbionts of Spodoptera frugiperda<\/em>, rapidly reversing insecticide resistance. It reduces chemical pesticide use and residue while increasing control efficacy, offering a precise, adaptable, and eco-friendly solution for sustainable management of resistant agricultural pests.<\/p>\n\n\n\n

Abstract<\/h3>\n\n\n\n

Invasive pest Spodoptera frugiperda<\/em>, known as the fall armyworm (FAW), evolves rapid resistance to chlorantraniliprole (CAP) via symbionts, reducing traditional control efficacy and causing economic losses. To address the formidable challenge of insecticide resistance, we introduce phage therapy into pest control, enabling precise targeting and efficient lysis of symbionts that mediate resistance. We employ zein to synchronously encapsulate phages and insecticides, constructing a nano-insecticide. This nano-insecticide ensures stability, exhibits robust performance by protecting phages against temperatures up to 60\u00b0C, and enhances their survival under UV irradiation by 83-fold. It intelligently responds to the pest gut enzymes for precise and controlled release, improving FAW control by 17% and overcoming resistance. Additionally, pesticide residue is reduced by 82.4%, with minimal impact on soil and maize microbial communities, preserving seedling growth. This modular, eco-friendly framework offers a sustainable solution for resistant pests, addressing the escalating challenge of resistant pests and paving the way for advancements in sustainable agriculture.<\/p>\n","protected":false},"excerpt":{"rendered":"
