摘要

To enable the artificial rearing of the main sugarcane stalk borers, Chilo sacchariphagus Bojer and Chilo infuscatellus Snellen indoors, this study presents a new suitable artificial diet and evaluates the rearing effects. We observed various indices of growth, development, and reproduction in C. sacchariphagus and C. infuscatellus, and performed statistical significance tests. The results indicated that the hatching rate, larval survival rate, pupation rate, and eclosion rate of C. sacchariphagus exceeded 80%. For C. infuscatellus, all indices except the pupation rate (72.22%) were above 80%. The total life cycle duration was 55.82 days for C. sacchariphagus and 47.67 days for C. infuscatellus. Female pupae of both species were heavier than their male counterparts. The oviposition rates of both species were higher than 85%, and female fecundity nearly 200 eggs/female. The net reproductive capacity (R0), the intrinsic rate of increase (rm), and the finite rate of increase (λ) of C. sacchariphagus were 151.8805, 0.0909, and 1.0952, respectively, while those for C. infuscatellus were 137.6163, 0.1176, and 1.1248. In conclusion, this artificial diet is well suited for the growth, development, and reproduction of the two sugarcane stalk borers and can serve as a standard diet for their indoor rearing.
