Abstract : An experiment was conducted to evaluate the effect of different artificial diets on the adult’s biological
attributes of sugarcane stalk borer (Chilo auricilius Dudgeon) and their costs. Considering the mean values of first and second generation
the maximum adult emergence (80.66 and 79.25), longer adult longevity (4.29 and 4.28), highest fecundity (233.45 and 225.98) and viability
of egg (216.25 and 208.74) was recorded on diets A and C. Also the sex-ratio on diets A (M:F::1:1.16) and C (M:F::1:1) favoured the
emergence of more number of females than males during development. On the basis of the economics also the artificial diets D, C and A
(Rs. 48.62, Rs. 48.32, Rs. 103.43, respectively) were found relatively cheaper than the natural food (Rs 166.67). Thus, the overall
performance of C. auricilius on diets A and C was found comparatively better than the other diets examined. Therefore, it can be used
as an alternate diet other than natural diet E (sugarcane) for the mass rearing of C. auricilius in the laboratory.
