Implication

Optimizes an artificial diet to enhance rearing performance and reduce costs for Carposina sasakii, suggesting practical benefits.

Key Points

The aim was to optimize a mass-rearing system for Carposina sasakii using artificially formulated diets.
Refined rearing by transferring newly hatched larvae directly onto fresh diet.
Implemented individual rearing in separate tubes.
Established a standardized diet replacement protocol, changing diets at specified intervals.
Developed novel diet formulations: CP, FS, and CPFS.
Populations reared on CPFS diet showed a significantly higher intrinsic rate of increase (r = 0.0854 d-1).
Finite rate of increase (λ = 1.0891 d-1) was also significantly higher in CPFS compared to apple-reared cohorts.
Net reproductive rate (R0 = 38.95 eggs) was significantly improved with the refined diet system.
The optimized rearing system reduced costs by 90%, achieving a daily cost of 58.00 CNY.
