Chemically-defined southwestern corn borer (SWCB) diet (Biomix 9763, Bioserv, Inc., Frenchtown, N.Y., USA) was successfully used for mass rearing Sesamia inferens. The larval duration averaged 22 days on SWCB diet as against 29 days from first to last larval instar on cut stems of susceptible Rexoro rice plants. The pupal duration and the incubation period of eggs laid by diet-reared moths were comparable to that on cut stems. Last-instar larvae and pupae obtained on SWCB diet weighed more than those from rice stems. Erect, rolled wax paper cylindrical tubes served as suitable oviposition substrates and facilitated easy removal and sterilization of eggs for rearing.
